All applicable legal or institutional installation regulations must be complied during installation.The device contains electrical and electronic components and must not be disposed of as household refuse. All locally valid regulations and requirements must be observed.Product featuresThe HVAC performance device is comprised of three components: characterized control valve (CCV), measuring pipe with flow sensor and the actuator itself. The adjusted maximum flow (V'max) is assigned to the maximum control signal (typically 100%). The HVAC performance device can be controlled via communicative signals. The fluid is detected by the sensor in the measuring pipe and is applied as the flow value. The measured value is balanced with the setpoint. The actuator corrects the deviation by changing the valve position. The angle of rotation α varies according to the differential pressure through the control element (see flow curves).Flow measurement All flow tolerances are at 68°F [20°C] & water. Flow rate curvesControl characteristics The fluid velocity is measured in the measuring component (sensor electronics) and converted to a flow rate signal.The control signal Y corresponds to the power Q via the exchanger, the volumetric flow isregulated in the EPIV. The control signal Y is converted into a linear characteristic curve andprovided with the V'max value as the new reference variable w. The momentary controldeviation forms the control signal Y1 for the actuator.The specially configured control parameters in connection with the precise flow rate sensorensure a stable quality of control. They are however not suitable for rapid control processes, i.e.for domestic water control. U5 displays the measured flow as voltage (factory setting).Parametrizing V'max with ZTH:U5 refers to the respective V'nom, i.e. if V'max is e.g. 50% of V'nom, then Y = 10 V, U5 = 5 V.Parametrizing V'max with PC-Tool:In the PC-Tool, the maximum flow rate to which U5 refers can be set individually. If V'max ischanged (e.g. to 70% V'nom), the U5 flow range is also automatically changed to the same value(e.g. 70% V'nom: U5 = 10 V). This adjustment can be reversed by entering a value manually (U5flow range = 100%: U5 refers to V'nom).As an alternative, U5 can be used for displaying the valve opening angle.Creep flow suppressionConverter for sensorsControl signal inversionHydronic balancing Combination analogue - communicative(hybrid mode)Manual override Flow controlV'nom is the maximum possible flow.V'max is the maximum flow rate which has been set with the highest control signal DDC. V'maxcan be set between 25% and 100% of V'nom.Given the very low flow speed in the opening point, this can no longer be measured by the sensor within the required tolerance. This range is overridden electronically.Opening valveThe valve remains closed until the flow required by the control signal DDC corresponds to 1% of V'nom. The control along the flow characteristic is active after this value has been exceeded. Closing valveThe control along the flow characteristic is active up to the required flow rate of 1% of V'nom. Once the level falls below this value, the flow rate is maintained at 1% of V'nom. If the level falls below the flow rate of 0.5% of V'nom required by the control signal DDC, then the valve willclose.Connection option for a sensor (active or with switching contact). In this way, the analog sensor signal can be easily digitized and transferred to the bus systems BACnet, Modbus or MP-Bus. This can be inverted in cases of control with an analog control signal. The inversion causes the reversal of the standard behavior, i.e. at a control signal of 0%, is equal to V'max, and the valve is closed at a control signal of 100%.With the Belimo tools, the maximum flow rate (equivalent to 100% requirement) can be adjusted on-site, simply and reliably, in a few steps. If the device is integrated in the management system, then the balancing can be handled directly by the management system. With conventional control by means of an analog control signal DDC, BACnet, Modbus, or MP-Bus can be used for the communicative position feedback.Manual control with push-button possible - temporary. The gear train is disengaged and the actuator decoupled for as long as the button is pressed.AccessoriesTools Description TypeConverter Bluetooth / NFC ZIP-BT-NFCWire colors:1 = black 2 = red 3 = white 5 = orange 6 = pink 7 = greyFunctions:C1 = D- = A C2 = D+ = BElectrical installationSupply from isolating transformer.The wiring of the line for BACnet MS/TP / Modbus RTU is to be carried out in accordance with applicable RS485 regulations.Modbus / BACnet: Supply and communication are not galvanically isolated.

For the valves to function correctly in the long term, they must be kept free from particle debris (e.g. welding beads during installation work). The installation of a suitable strainer is recommended.Ball valves, rotary actuators and sensors are maintenance-free.Before any service work on the control element is carried out, it is essential to isolate the rotary actuator from the power supply (by unplugging the electrical cable if necessary). Any pumps in the part of the piping system concerned must also be switched off and the appropriate slide valves closed (allow all components to cool down first if necessary and always reduce the system pressure to ambient pressure level).The system must not be returned to service until the ball valve and the rotary actuator have been correctly reassembled in accordance with the instructions and the pipeline has been refilled by professionally trained personnel.The direction of flow, specified by an arrow on the housing, is to be complied with, since otherwise the flow rate will be measured incorrectly.Before installing the valve, the circuit must be thoroughly rinsed to remove impurities. The valve must not be subjected to excessive stress caused by pipes or fittings.Inlet sectionSplit installationBehaviour in case of sensor failureIn order to achieve the specified measuring accuracy, a flow-calming section or inflow section in the direction of the flow is to be provided upstream from the flow sensor. Its dimensions shouldbe at least 5x DN.The valve-actuator combination may be mounted separately from the flow sensor. The direction of flow of both components must be observed.General notesIn case of a flow sensor error, the EPIV will switch from flow control to position control.Once the error disappears, the EPIV will switch back to the normal control setting.DimensionsDimensional drawingsTypeWeight EP200H+ARX-E N415 lb [6.7 kg]ABCD E F26.6" [675]13.9" [353]12.0" [305]10.2" [260] 3.4" [86]3.4" [86]。

The Future of Commercial Hot Water HeatingTable of ContentsO1. Introducing Heat2O and heat pump basics2. Heat23. Cold climate performance and scalability4. System design5. Installation requirements and maintenance6. Improved installation quality7. Controls and benefits for utilities8. Applications1Commercial hot water heating for the futureDomestic hot water accounts for roughly 25% of annual energy usage in typical multifamily buildings 1 and 25% in both passive house 2 and new, multifamily construction 3. This energy expenditure is costly for building owners and comes at a significantenvironmental impact in the form of greenhouse gas emissions and climate change.Until recently, the building industry lacked an energy-efficient solution to providing high volume domestic hot water (DHW) for commercial spaces. In response to this need, we’re pleased to introduce the Heat 2O™ Hot Water Heat Pump, a revolution in sustainable water heating.Introducing Heat2OHeat 2O is an all-electric heat pump water heaterdesigned to produce high volume DHW for commercial facilities in any climate. Energy-efficient andenvironmentally friendly, Heat 2O uses a natural CO 2 refrigerant with a global warming potential (GWP) of one and an ozone depletion potential (ODP) of zero.As an engineered solution with manufacturer-level technical support, Heat 2O is fully customizable to best meet the design considerations and priorities of a broad array of application types. This technology can help multifamily buildings, offices, gyms, educational institutions and other large-scale and commercial facilities qualify for sustainability certifications or achieve zero-energy and passive house status. The system’s environmentally conscious engineering also translates to energy savings for building owners, who experience reduced operating costs while their tenants and occupants enjoy reliable hot water.These benefits can be enjoyed regardless of location. Climate zone is not a limiting factor for this innovation, as Heat 2O’s high-performance design allows the system to operate at high capacity even in cold climates.Buildings from the hot American Southwest to snowy New England can experience high performance and energy savings with Heat 2O, all while minimizing their carbon footprint.1 U.S. Energy Informational Administration2 Passive House Institute US3 Bonneville Power Administration2Heat2O™ and heatpump basicsDHW heat pump water heaters transfer ambient thermalenergy from outdoor air to potable water by cyclingrefrigerant. Natural CO2refrigerant enables Heat2Oto supply hot water up to 176° F even in low ambientconditions. The heat pump’s fan pulls outdoor air acrossan evaporator coil where liquid refrigerant absorbs heatas it changes to a low-pressure gas. With the refrigerantcarrying heat captured without burning fossil fuels, theheat pump’s compressor pressurizes the gas raising thetemperature and transfers the refrigerant to a gas cooler.The gas cooler then transfers heat from the superheatedrefrigerant gas to the incoming city water. This isaccomplished without the use of fossil fuels reducing thecarbon footprint associated with water heating.Heat2O uses a Twisted Spiral Gas Cooler unique toMitsubishi Electric. This patented technology achieveshighly efficient heat exchange with three refrigerantlines wrapped around a twisted water pipe. Therefrigerant flows in the opposite direction of the water.Running the refrigerant lines along the pipe’s groovesincreases the heat conductive area while the spiral helpscreate a vortex in the pipe, accelerating the turbulenceeffect of water and reducing pressure loss in the heatexchanger. Additionally, the copper pipes make fordouble-walled construction.An INVERTER scroll compressor further increases Heat2O’senergy efficiency by enabling the system to modulatethe refrigerant flow and heating capacity to match loads.Variable capacity gives the system greater control overenergy use than fixed-capacity hot water heat pumps.Using these methods, Heat2O offers a coefficient ofperformance (COP) of up to 4.52, meaning it can provideover four times more energy as heat than it consumes inelectricity. Compared to electric-resistance water heaters,Heat2O offers energy savings of 60 to 70% for buildingowners and tenants. Combined with incentives fromutilities, energy savings can ultimately offset first costs.3Cold-climateperformance and scalabilityFlash injection circuitHeat 2O continues to deliver 100% heating capacity at ambient temperatures of 36° F and can supply 176° F hot water at temperatures as low as -13° F . This performance is achieved through flash-injection technology. In extreme cold, Heat 2O’s compressor operates at speeds much higher than usual tomaintain discharge pressure and keep the evaporator’s refrigerant cool enough to capture ambient heat. The injection circuit supplies a small amount of mixed-phase refrigerant to the compressor through a specially designed port, ensuring stable operation at highspeeds. With Heat 2O, even building owners in climate zones 5 and 6 can increase sustainability while reducing energy costs for high-volume DHW. Performance:• 100% water heating capacity of 40 kW at ambient temperatures as low as 36° F• 50% water heating capacity at ambient temperatures as low as -13° F (176° F water temperature)ScalabilityHeat 2O can provide highly efficient DHW for most commercial buildings, including large-scale facilities. Using Mitsubishi Electric’s unique Mitsubishi Network (M-NET) communication protocol, the system can be scaled, connecting up to 16 Heat 2O units together. While nominal system capacity is 40 kW (136,484 BTU/H), M-NET allows all units to communicate with one another, enabling cascade operation and acombined total capacity of 2,183,770 BTU/H (640 kW). Units run at the same compressor frequency to achieve a stable leaving water temperature set point. Thislevel of performance is ideal for applications requiring high volumes of hot water on-demand, including universities, hotels and other large facilities.64,83051,180OUTDOOR TEMPERATURECAPACITY (BTU/H)Heating CapacitySystem designOptimal performance and cost benefits for all-electric heat pumps require proper design, installation and commissioning. This starts with cooperation and information exchange among project team members, including the developer or building owner who will decide whether the facility will participate in utility demand-response programs. Designers must understand the building’s demand profile, inclusive of the gallons per hour, duration and timing associated with peak loads and off-peak loads. The system’s storage capacity is based on how often the system will run. Additionally, designers account for climate and may make provisions for snow, rain, wind and marine salt.The Heat2O project team typically includes plumbingengineers, electrical engineers and control engineers. Each trade and discipline should be involved in the earliest stages of the project. The team will also include Trane®/Mitsubishi Electric employees responsible for thestartup and commissioning of each Heat2O system.Design for hot waterrecirculationHeat2O designs account for hot water recirculationby separating DHW loads. The heat pump waterheater handles the difference between the inlet citywater temperature and the leaving temperature. Therecommended inlet temperature range is 41° F to145° F, but a high Delta T between inlet and outlettemperatures provides optimal efficiency.The building’s recirculated water is warmer than inletcity water and is often outside the optimal temperaturerange recommended for the heat pump. To avoidderating and ensure the availability of hot water, Heat2Odesigns include a primary storage tank and a swingtank. Heat2O conditions the cool incoming city waterat the bottom of the primary storage tank while thehot water moves to the top, maintaining temperaturestratification. During hot water production, the systemcan feed high-temperature water to the swing tank,which also mixes with warm recirculation water. Waterwithin the swing tank is maintained within a specifiedtemperature range, for example 125° F to 150° F. TheHeat2O swing tank includes a control panel with threeelectric heating elements for temperature maintenance.Typical Systems SchematicTANK PUMP HOT WATER RECIRCULATING PUMP45Heat 2O is typically installed outdoors with common considerations for airflow, space, structural support, acoustics and service access common to heat pumps. Each Heat 2O unit must be individually wired to its own dedicated power supply and have one-foot minimum clearance for air intakes. Installation of cold-water inlet and hot-water outlet piping is straightforward.MaintenanceMaintenance primarily consists of maintainingcleanliness. Install a strainer near the Heat 2O unit to keep foreign materials from entering the water-side heat exchanger. Clean the external heat exchanger, clean strainers periodically and ensure the internal heat exchanger and secondary heat exchanger are free ofscaling and debris.Heat 2O at a glance• Height: 72.5"• Width: 48"• Depth: 30"• Weight: 882 lbs • Electrical: 208/230V • Sound: 60 dB(A), no louderthan a conversationInstallation requirements and maintenance6Improved installation qualityAs a custom solution, Heat 2O includes a complement of parts designed and selected to ensure optimal performance of the heat pump. Using pre-approved parts help control the quality of installations and streamlines the work with pre-assembled and pre-plumbed components.Hot water storage tanksPrimary storage tank: Includes 6 thermistor locations for more precise measurement of water temperatures compared to most storage tanks, which typically have one thermistor.• Sizes: 175 gallons, 285 gallons, 500 gallonsSwing tank: Includes electric-resistance elements for the ability to maintain specific temperatures in the swing tank and can provide up to 100% backup capacity for the heat pump.• Sizes: 150 gallons (with 45 kW electric-resistance element) and 200 gallons (54 kW electric-resistance element)Secondary heat exchanger: Creates a closed loop to protect Heat 2O from scaling and corrosion from city water, reducing maintenance requirements.Variable-speed secondary circuit pumps: Varies capacity on secondary circuit according to demand. The speed is controlled using a 0 to 10V signal from the Heat 2O units.Heat 2O Components and TanksEXTERNAL COMPRESSORSTORAGE TANKS SWING TANK HEAT EXCHANGER7Controls and benefitsfor utilitiesComprehensive control for efficient operationA pre-engineered controls package is available to further enhance Heat 2O’s operation and efficiency. This package seamlessly integrates the heat pumps, tanks, pumps, valves and sensors to monitor and control the system. No additional programming or licenses are required to add the controls to the hardware. An interactive setup guide makes the startup and commissioning process intuitive and easy to follow. Local users can monitor and control operation, modes, set points and tank capacities with the touch screen display through the site local area network or through BACnet ® integration to a building management system (BMS). The built-in Energy Monitoring Capabilities and Demand Response Rebate Program (CTA-2045) enables Heat 2O to react to demand-response signals from grid operators. Internet access and increased capabilities are available through connection to the Building Connect + cloud-based controls platform.Building Connect + features:• On/Off mode, temperature mode control and tank temperature set point • Start-up wizard • Maintenance tool data • Flow diagram • Energy use dashboard • Data trending • Alarm managementDemand response and utility benefitsDuring demand-response events, utilities shift energy use to prevent electricity grids from overloadingduring peak usage times. Building owners can qualify for utility incentives by participating in demand-response programs. Able to send and receive messages defined by the CTA-2045 specification, Heat 2O can simplify participation with a utility virtual end node integrated into the system’s control panel.Heat 2O units operate at 40 kW in normal mode. In advance of demand-response events, the system can run at 60 kW in capacity mode to fully pre-load tanks with hot water. Once the tanks are depleted, Heat 2O can reactivate so building occupants have uninterrupted access to hot water. Primary thermal storage tanks with swing tanks for recirculated water enable the system to handle a higher peak demand.8HEAT 2OSEALED HOT WATER STORAGE TANKS X 3HOT WATERRECIRCULATION PUMPMIXING VALVESECONDARY HEAT EXCHANGERSECONDARY PUMPSWING TANKApplicationsMultifamily (Hot Water Recirculation - Swing Tank Required)Fitness Center (No Hot Water Recirculation - No Swing Tank)HEAT 2OCITY WATER CONNECTIONSTORAGE TANKOutlet hot water piping Inlet water pipingSECONDARY HEAT EXCHANGERSTOutlet hot water pipingInlet water pipingSpecificationsQAHV-N136TAU-HPB-(-BS)Notes: Unit converter*1.Under Normal heating conditions at the outdoor temp, 16°CDB/12°CWB(60.8°FDB/53.6°FWB), the outlet water temperature 65°C(149°F), and the inlet water temperature 17°C(62.6°F)*Do not use steel pipes as water pipes.*Keep the water circulated at all times.

热浇道系统简介现时常见的热浇道系统，主要由分流板、热咀和温度控制器三大部份组成。
热浇道系统是透过精密的温控手段，将熔融塑料通过精密设计的分流板和热嘴，直接输送至模腔里，其好处包括：有效减低浇道的压力；熔体的流动性得到提高；材料密度均匀；产品的内应力减少，使产品获得较小的变形、较好的产品表面质量和力学性能。
热浇道系统的另一特点，是热嘴直接将熔融塑料注入模腔内，在脱模的过程中，浇口自然断开，消除了传统注塑工艺带来的浇道废料，除免去处理浇道废料的后加工工序外，更消除了废料所带来的附加热量，缩短冷却时间，获得更快的生产周期。
热浇道技术已成熟要获得理想的注塑效果，热浇道需要确保其内的塑料熔体在注射、保压和冷却阶段保持正确的温度。
最早期的热浇道系统，在温度控制上未臻完善，随着后期的逐步改良，现时的热浇道技术已相当成熟。
本文会简介热浇道的发展简史和其基本结构，希望加深读者对这方面的认识。
绝缘式浇道系统绝缘式浇道系统是最早期的热浇道系统，其工作原理是昨用塑料本身极低的热传递系防止热量散于失于模板中，以保持塑料的熔融状态。
在浇道的设计上，口径尽量加大，以使浇道中央的塑料在首次充填后，借着塑化材料不断地流通而保持熔融。
至于浇道最外层接触模板的塑料，会因遇冷而凝结成固化层，在固化层中间就是不断流通的塑料通道。
一旦形成固化层，在熔融塑料与模板间会产生不错的绝热效果，足以确保熔融塑料在快速连续地生产下不致发生浇道全面凝结。
但是只要有任何短暂的生产停顿，还是不能避免整条浇道的固化。
绝缘式浇道难于控制熔融塑料温度这种原始的热浇道系统难于控制熔融塑料的温度，导致浇道冷凝与浇口阻塞的现象不断发生。
为了解决此问题，就有了热探捧的出现，即在浇口前的通道中，加装一支管形加热器，藉此控制熔融塑料的温度，同时，浇口的控制、成品的顶出均获得改善。
事实上，早期的绝热式浇道系统只适用于低黏度塑料，随着高黏度及成型性较差的工程塑料的不断出现，对流动通道中熔融塑料的温度控制也越重要，所以又衍生出歧管式浇道系统。
热流道的原理及应用图解1. 热流道的定义热流道（Hot Runner）是一种塑料模具的加热系统，它通过将热能传输给模具中的塑料来加热塑料，使其融化成型。
相比于传统的冷流道（Cold Runner）系统，热流道系统具有更高的生产效率和更好的产品质量，被广泛应用于塑料制品的生产过程中。
2. 热流道的工作原理热流道系统由一套加热系统和流道系统组成，其工作原理如下：2.1 加热系统热流道的加热系统一般由加热器、热流道管和热流道控制器组成。
加热器通过加热元件将电能转化为热能，使热流道管内的热媒介（通常是热油）被加热。
热流道控制器可以实现对热流道的温度、流量等参数进行精确控制。
2.2 流道系统流道系统是热流道的关键组成部分，它负责将加热过的热媒介传递给模具中的塑料。
流道系统通常由主流道、分流道和喷嘴组成。
•主流道：主流道是热流道中最重要的一部分，它负责将加热过的热媒介传递给分流道和喷嘴。
主流道的尺寸和布置对于塑料的流动和充填起着重要作用。
•分流道：分流道将主流道中的热媒介分流到各个喷嘴上，使得每个喷嘴都能独立地控制塑料的温度和流量。
•喷嘴：喷嘴是塑料的最后成型部分，它负责将加热的塑料注入到模具腔中。
3. 热流道的优势和应用相比于冷流道系统，热流道系统具有以下优势：3.1 提高生产效率由于热流道系统中的热媒介可以保持在适宜的温度，使得塑料在注射过程中保持良好的流动性，从而减少了注射时间和冷却时间，提高了生产效率。
3.2 降低生产成本热流道系统减少了冷却时间和废品产生，降低了生产成本。
同时，由于去除了冷道系统，可以减少注塑机的锁模力，降低了设备的投资成本。
3.3 改善产品质量热流道系统可以精确控制塑料的温度和流量，保证了每个喷嘴注入的塑料质量一致，减少了产品的热变形和缺陷。
热流道系统在以下领域有广泛的应用：•医疗器械：热流道系统被广泛应用于制造医疗器械，如注射器、输液器等。
由于产品的精度和质量要求较高，热流道系统能够满足其生产需求。
返回上页1、客户加工阶段(如下图所示)※1 G和d4应保持同心※2 d4和W应保持垂直※3 d1和d4之间应保持同心（非常重要）※4 为防止漏胶，d4的尺寸大小十分重要，应保持与热喷咀高质量配合※5 对浇口部位进行精密的加工处理，要保持精度和光洁度※6 热咀开框时要加上膨胀量E（E=L*注塑温度*0.0000132）※7 要正确设计浇口冷却系统，当浇口冷却不充分时，会使加工周期变长，有时会产生流涎现象。
一般冷却水孔距封胶位最小8mm，对一些表面要求较严格的产品可采用运水套的冷却形式。
2、当对热咀进行安装时应注意※1 热喷咀应小心安装※2 防止划伤或碰伤已磨削的表面※3 用溶剂清除防锈油※4 小心将热喷咀放入安装孔中,轻轻压入到位※5 在安装完毕前,将导线放入线槽中,不要用导线拉动或转动热喷咀,安装时要确保加热丝和热电偶的导线不会被过分折弯或被破坏※6 在一模多腔情况下,检查确保所有热喷咀的W面在同一平面(平面度误差为+/-0.02) ※7如图所示,保证热喷咀与模具在接触时维持最小接触面积※8 检查所有热喷咀安装高度，确保正确后热分流板方可被装入模具中，一切就绪后再安装O型金属密封圈。
※9 当加热到设定温度后,用一条软线(如保险丝线)检查热喷咀在热状态后咀尖与浇口之间的间隙,周围的间隙必须保证均匀,如果没有间隙或者间隙太小(小于0.2mm),请检查浇口规格和E值计算结果是否正确.※10 安装后都要对电路控制系统进行检查，以确保能正常运行。
（用万用表检测）3、安装热分流板按以下程序正确计算热喷咀和热分流板的膨胀量，是防止漏胶的重要条件：※1 测量热分流板、钢垫块、钛合金垫块、L的总高度。
※2 然后测量整个为安装热喷咀及热分流板所制作的空间，使尺寸完全达到要求，如测量从W面到定模固定板（底板）的高度等等。
※3 在工作温度下,热分流板钛合金垫块与定模固定板(底板)之间有0.05mm的过盈量，这个距离通过磨削钢垫块进行调整。

第四节热流道浇口的类型和结构一、开放式浇口：开模时，浇口中的部分材料留在产品上，从而造成了一个难看的浇口痕迹（通常是锥形的）。
浇口残痕的大小和形状取决于浇口的形状及注塑参数（温度，压力，时间），也取决于模具的设计，同样或甚至更多地取决于模具装配。
在下一次循环时，塑料料流将模塞（上一啤浇口处冻结的料）挤入型腔，浇口又打开，料流又可以填充模具，通常情况下模塞可以熔化，与注入塑料混合；在浇口对面做一弧形缩窝，有利于模塞的隐藏，有利于填充。
适用于没有或几乎没有“拉丝”倾向的塑料，还适用于PP种PE料。
开式浇口有三种基本类型：圆形浇口，环形浇口，边缘浇口。
1.1）圆形浇口：缺点：浇口L段的断开点不确定，可能会在L方向上的任一点断，并在产品上留下一很长的突起。
优点：这种浇口较易于加工制造。
此时，将浇口形状修改成下面的形状，则断点一致，在高于产品的锥形突起部位断开，虽然，在断点上还会有一个小锥形突起，但总的突起部分或多或少可以预测。
于控制热损失的开式浇口设计1.2）环形浇口：实质是一个在其中心部加入加热探的开式浇口，以防止过早冻结。
需要注意的是浇口形状与注嘴梢部的开状密切相关。
下图是在浇口中心有一个加热探头的环形浇口，由于注嘴梢位于浇口内而形成了一个环形通道，进入模具腔的塑料就像一个挤出的管子。
塑料充满了注嘴和其周围（冷却的）模腔之间的不导体，几乎不会有什么热量穿过这层塑料隔热罩。
在成型热稳定性差的塑料时，需要成型一个或机加工一个耐高温的塑料隔热罩，现一般是用杜邦Vespel 全芳香族聚酰亚胺(PI)塑料制作。
Vespel 的特点：1. 耐热性：连续使用耐热温度可达288°C ，短时间使用更可高达480°C 。
2. 耐磨耗性：Vespel 的无润滑限界PV 值是一般工程塑料的10倍以上，对冲击磨耗和摇动磨耗都有很强的耐性。
3. 蠕变(Creep)：在260°C 、186kg/cm2条件下的蠕变，1000小时只有0.6%。

Type of fluidsPlease consult with SMC when using the product in applications other than compressed air.2. Large amount of condensateCompressed air containing a large amount of condensate can cause malfunction of pneumatic equipment. An air dryer or water droplet separator should be installed upstream from filters.3. Draining controlIf condensate in the drain bowl is not emptied on a regular basis, the condensate will overflow and enter the compressed air lines. This will cause a malfunction of pneumatic equipment. If the drain bowl is difficult to check or remove, installation of a drain bowl with an auto drain option is recommended.4. Use clean air.Do not use compressed air that contains chemicals, synthetic oils, including organic solvents, salt or corrosive gases, etc., as it can cause damage or malfunction.For detailed information regarding the quality of the compressed air described above, refer to SMC's "Air Cleaning Systems".1. If ultra dry air is used as a fluid, the lubrication characteristics of the equipment will deteriorate and this can affect the reliability (life) of the product. Contact SMC beforehand, if using ultra dry air.2. Install air filters.Install air filters close to valves on the upstream side.It is strongly recommended to use a filter with a filtration rating of 0.01 μm or less. Be careful to prevent the supply pressure to the valve from decreasing.3. Take appropriate measures to ensure air quality, such as by providing an after cooler, air dryer, or water separator.Compressed air that contains excessive drainage may cause malfunction of valves and other pneumatic equipment. Therefore, take appropriate measures to ensure air quality, such as by providing an after cooler or water separator.4. If excessive carbon powder is seen, install a mist separator on the upstream side of the valve.When the amount of carbon particles generated from the compressor is excessive, they will stick inside of the valve, and may cause malfunction or internal leakage.Refer to SMC’s Best Pneumatics catalog for further details on compressed air quality.Operating environment1. Do not use in an environment where corrosive gases, chemicals, sea water, water or steam are present.2. Do not use in an atmosphere containing flammable or explosive gases.

安装流程：
1) 检查模具尺寸与设计图纸相符后依次将喷嘴封胶面与喷嘴安装基准托面喷上红丹，轻轻装入模具。
确认热流道喷嘴装到位后，再将喷嘴取出，看喷嘴封胶面与托位面的配合是否到位。
如配合不好或不到位找出原因，如配合完好再依次将喷嘴装入模具并确认装到位，然后用深度尺测量喷嘴高出模具 A 板的高度（一般的标准是10cm）
2) 插入中心定位销、止转定位销、中心垫块，然后将密封圈放入热流道的上端面“O”型环槽内。
3) 安装分流板、﹙用螺丝锁紧分流板﹚、上承压垫块、热流道分流板热电偶。
4) 为了便于配线，将各电源引出线、热流道热电偶引出线，用号码管进行编号。
5) 装配完毕后用深度尺测量分流板上承压垫块是否与分流板垫板的高度相同（一般的标准是上垫块高出模具垫板10～20 司），确认高度后盖好模具盖板并锁紧盖板螺丝。
6) 配线：把电源线放入出线槽并用压线板固定，确认后剪掉多余的线，嵌入φ2-3 接线头。
确认接插件：HUIGER的标准为电源线接公芯接插件，热流道热电偶接母芯接插件。
7) 现场接线一般有两种情况：一种按照HUIGER的接线方式接入接插件。
另一种按照客户提供的接线方式接入接插件。
8) 配线完毕后再将接插件装入接线盒并固定在模具上。
9) 装配完毕后用万用表检测（热流道加热器与热电偶）的电阻值与绝缘值是否正常。
注意事项：
1.摆好模具，放平上模，用风枪清理所有孔位及模板。
2.检查各孔位尺寸，重点检查深度。
清除模板上的毛刺。
同时查看锁分流板的螺孔，及

这个地方第一次做热流道模具的师傅经常会漏做。
3.将热咀封胶位和上台阶位这两个与模具配合的部位扫红丹。
4.将热咀试装，然后拆出检查封胶位是否擦到红丹，台阶位是否碰到模具。
如果没有，停止安装，检查误差原因进行调整。
确保配合紧密不漏料。
此过程注意不要碰伤咀尖。
5.将热咀全部装好，同时装好中心垫、中心销、防转销。
并在其平面上扫红丹。
6.检查咀平面及中心垫高度，误差控制在0.05mm以内。
7.试装分流板。
注意正式装分流板时不要漏装热咀密封圈。
8.检查分流板与热咀的配合，保证全部碰到红丹，确保不漏胶。
9.整理热咀走线，做到整齐美观，并将线路每组按顺序编号。
将线接入插痤。
10。
将分流板正式装入，锁紧分流板固定螺丝(注意一定要锁平衡，保持分流板的四角高度一致)，控制分流板介子高于周边模框平面0.10-0.15mm，然后在分流板介子上扫红丹。
11.将码模板试装，检查平面是否碰到介子红丹，确保模板压住分流板介子。
12.锁紧模具，将模具立起，从分型面检查浇口与咀尖的配合是否达到要求。
做到咀尖低于浇口面0.1-0.2mm，咀尖不能偏心。
用万用表仔细检测每组电路，做到无短路、断路、漏电等，各组线路对应无误，确保所有电路正常。
接好温控器进行试加温，第一次加温应在100度以内保持十分钟进行预热除湿，保护加热器。
然后加温到需要的温度，正常的话即可安排吊装模具试模。
