涡轮分子泵电源说明书

Features:The Turbo™ 90 is designed to operate directly from a 1000RPM PTO shaft without attachments. Peak performance at slower rotation means longer life of the seals. The Turbo 90 can pump suspended materials without accumulation unlike a conventional turbine pump. This is possible because of Pressure Relief Passages from the seal cavities to the inlet port. The sus-pension circulates, and therefore is cleaned from the inner cavi-ties. It can be used for large quantity liquid transfer, from truck to tanks, for instance. It is well suited to high volume sprayer pumping applications.The impeller is made of low moisture absorption, corrosion-resist, engineering grade thermoplastic. It has been designed to increase pump life and smooth operation because of less rotation weight. Seals available are either face seals or lip seals. Specify face seals for severe service (such as abrasives). Face seals feature hard, wear-resistant phenolic rings pressing against ceramic seats.Bearings are isolated by drain cavities. 1 1/2” inlet and outlet ports permit unrestricted high volume flow. Because of the high capacity of the Turbo 90, sufficient bypass flow is available to main -tain maximum agitation. Shaft is made of stainless steel and has a 15/16” diameter with 1/4” keyway.Severe Service model: A Turbo 90 pump is available with a stain-less steel impeller and long life face seals for severe service. The stainless steel impeller will not swell or absorb chemicals because of its steel construction; is tough, durable and virtually indestructible; and is corrosion resistant.Caution: Failure to use a suction strainer, as specified, may void the product warranty.Note: A high capacity strainer with a 20-mesh screen must be used on the inlet side. Note: A 1000 RPM PTO coupler must be used. The capacity or flow of the Turbo 90 pump used with a 540 RPM PTO coupler is about zero.1000 RPM Quick Couplers: Quick couplers provide quick and simple on-off installation. The body is steel and the collar is Super T ough Nylon, color-coded International Orange for 35979, 1 3/8” PTO Coupler, and International Yellow for 35992, 1 3/4” PTO Cou-pler, according to safety standards.Collar Coupler: This coupler reduces the chances of vibration be-cause it clamps a full 360º on a 15/16” pump shaft, and on either 1 3/8” or 1 3/4” tractor PTO, like a collet. This provides better center-ing of the pump shaft to the tractor PTO. Both ends of the coupler must be wrench tightened onto the PTO shaft and the pump shaft prior to operation.Note: Do not force coupler onto the PTO spline too far. 1/4” to 3/8” of PTO spline should be visible after coupler is in position.Torque Bar and Chain: This part is needed to anchor a pump mounted directly on a PTO to keep it from turning with the PTO shaft.Turbo 90 Repair Kits: 28455-1 repair kit for 26556-11 cast iron pump with face seals includes one gasket, two seal rings, for O-rings, two ceramic seats, two seat rings, two springs, and two seal supports. P/N 28455-2 repair kit for 26556-4 cast iron pump with lip seals includes one gasket and two lip seals.Warning: When using PTO-driven equipment, leave shields in place. Do not wear loose-fitting clothing near rotating PTO shafts.Turbo™ 90 Flow Rates — Gallons per minutePump G ALLONS PER MINUTE (GPM) AT POUNDS PER SQUARE INCH AT THE GAUGE (PSIG) Speed (RPM) 0 10 20 30 40 50 60 70 80 90 100 600 45 30 19 8 — — — — — — — 800 60 47 37 27 19 11 3 — — — — 1000 75 65 55 46 37 30 24 18 12 6 —12009080736557494236312520Figure 1. Plumbing for Pump InstallationWhen using a quick coupler, line up key in thequick coupler with keyway on pump shaft and slide coupler into place, also lining up other set screw with spot on shaft. Tighten the set screw over the spot on the shaft first, then the keyway set screw.When using quick couplers, pull collar back andslide onto the PTO shaft until it locks into place, release collar.When using a Collar Coupler, slide onto pumpshaft, then PTO shaft, leaving 1/4” to 3/8” of PTO spline visible. Tighten both ends of the coupler witha wrench.Position pump below liquid level in tank to assurepriming.On other than PTO installations, check pumprotation. An arrow on the pump shows direction of rotation.To keep pump from rotating with PTO shaft, usea torque bar and chain assembly 33680 (Fig. 3). Bolt bar to pump, using two adjacent flange bolts. Snap one end of chain to the torque bar and the other end to a stationary part of the tractor. Mount the torque bar so the counter force will raise up onPump Installation1. 2. 3. 4. 5. 6.7. 8.9.10.11.the pump and help relieve the side pressure due to weight of the pump and hose. Do not fasten pump rigidly to the tractor.With the pump in position, connect the inlet hose to the IN port. Use a 1 1/2” I.D. hose if you need maximum flow rates (Fig. 1).A high capacity strainer with a 20-mesh screen must be used on the inlet side (Fig. 1). For in-line protection of nozzles, use a 40-mesh strainer in the boom feed line. Use a 3/4” or 1” Y-type strainer (Fig. 1).To regulate pressure, install either a 1 1/4” ballvalve or 1” pressure regulating valve downstream from the pump discharge (Fig. 1). Do not use a spring-loaded valve.Check all hose connections. Loose connections can permit air to be drawn in and the pump may not prime properly.Note: Support hoses where necessary to keep weight off the pump.Caution: Failure to use a suction strainer, as specified, may void the product warranty.Pump MaintenanceBearings require no lubrication. Drain. If pump remains installed on tractor,remove drain plug to drain pump. If pump hasbeen removed from tractor, use IN and OUTports for draining.Flush. After use, thoroughly flush pump with clearwater. If available, use a solution of one cup ofammonia in 10 gallons of water. This will dissolvemost residue remaining in the pump. Drain, let dry,then flush pump with light lubricating oil. Store.Caution: Gasoline, kerosene or fuel oil can attack materials in pump. Do not use as storing solution. If pump is to be stored, follow flush with a 50 percent permanent antifreeze solution. Plug ports.Maximum Recommended Pressure:100 PSIG (7 Bars)Maximum Recommended Temperature:120º F (50º C)Maximum Recommended PTO Speed:1250 RPMBefore starting, make sure all air is removed frompump and lines.Do not use rusty supply barrels or sandy water.Caution: Running pump dry can cause exces -sive heat and damage seals.Do not start pump before priming. The pump is NOT self-priming. Be sure suction line and pump are filled with liquid. Open the pressure regulating and boom regulating valves to be sure there is no back pressure on pump. Do not close the discharge line of the pump unless a means of bypassing the liquid relief valve has been installed. Pump can then be started and should prime. To assure ease in prime and the bleeding of air in pumping system, install pump so that ports are upright.Caution: Operating above maximum limits candamage pump.Do not operate pump at a PTO speed in excess of1250 RPM, or a pressure higher than 100 psi (7 bars), or a temperature higher than 120º F (50º C).Pump Operation1. 2. 3. 4. 1.2.3.4.Figure 2.

nEXT TURBOMOLECULAR PUMPSEDWARDS THE PARTNER OF CHOICEEdwards is a world leader in the design, technology and manufacture of vacuum pumps with over 95 years’ history and more than 75 years’ manufacturing experience.We believe in delivering results that bring value to our customers by using our breadth of industry experience to identify and apply solutions to your problems. Using the most innovative and up-to-date modelling techniques and know-how, we can optimise the pumping configuration to achieve the maximum performance in the most reliable and cost-effective way.ApplicationsResearch & Development»Chamber evacuation, coating systems,turbomolecular pump systemsHigh Energy Physics»Beam Lines, accelerators, mobile pump carts, Electron Microscopy»TEM, SEM, EPMA, sample prep benches Industrial»Glove boxes, coating systems, XRD/XRF systems, lamp evacuationnEXT240 nEXT300 nEXT400 The pump name refers to the true peak pumping speed for nitrogen gas.BOOST TECHNOLOGYFor our Analytica Instrument OEMs the “T” variants of nEXT employ a unique viscous pumping stage which can be used to ‘boost’ the performance of the backing pump. This offers a much simplified vacuum solution with greatly improved pumping speeds and system power reduction. The example in the image below shows how the boost ports can be used to replace a primary pump on a differentially pumped system.Customers in general laboratory and R&D applications will also benefit from the improved compression achieved with the "T" variant. To take maximum advantage of boost technology, please contact Edwards.END USER SERVICEABLITYNew technologies employed in nEXT have enabled the pumps to be serviced by the end user in the field. An interim oil lubrication cartridge change can be performed, where access allows, typically in less than 5 minutes and a full bearing change can also be performed by the end user in around 10 minutes both with the minimum of specialist tooling. These simple interventions will, in many cases, mean that the pump never requires a full return to base service during its lifetime.nEXT turbomolecular pumps will advise the user when aservice is due and what level of intervention is required.The user is alerted to a service request by a simple flashingLED sequence on the pumps and by serial comms notification.Flexibility is again key as these simple services can beperformed either by the end user, on site by an EdwardsField Service Technician, or the pump can be returned to anEdwards service hub.Using remote diagnostics, a user can interrogate the pumpto determine how long it is to the next service so that aproactive approach to preventative maintenance can beplanned.systems for maximum system rationalisationnEXT300 turbomolecular pump sectional viewintegration* a smaller backing pump may be used depending on application.Controllers and AccessoriesThe TIC (Turbo and Instrument Controller) automatically recognisesand supports one turbomolecular pump from the nEXT range, plusthree Edwards active gauges. Cooling and vent valve support is provideddirectly from the controller. Backing pump power is provided for acompact 24V diaphragm pump (on 200W versions only), or where greaterpumping speeds are required, mains backing pumps (up to RV12) may becontrolled via an optional relay box.nXDS and large XDS pumps can be controlled directly via the backingpump connector on a TIC 200. The relay box can also be used to controla mains heater band and backing line isolation valve. Time delays andnormal speed signals may be used to control events such as turbo startand there is a comprehensive selection of protection and safety interlockfeatures. The TIC turbo controller may be either rack or bench mountedand provides a useful hub for the flexible operation of a wide range ofvacuum system configurations.The TAG (Turbo and Active Gauge) controller is a small,compact, low cost pumping system controller, which issuitable for a wide range of vacuum applications. It is a 24Vcontroller that is compatible with all Edwards DX and nEXTturbomolecular pumps. It contains no power source andtherefore you either need to supply your own power or buythe optional power supply. In addition to a turbomolecularpump it can control a backing pump, a vent valve, an aircooler and an Edwards active gauge. The TAG Controlleris controlled by an easy to use interface. A large clear LEDdisplay shows the pump speed or vacuum pressure. Thecompact size of the controller is ideal for use on bench-topsor suitable mobile platforms.nEXT Turbomolecular PumpsEDWARDSnEXT240 nEXT300 nEXT400EMEAUK+44 1444 253 000(localrate************ Belgium+32 2 300 0730 France+33 1 4121 1256 Germany 0800 000 1456 Italy+ 39 02 48 4471 Israel+ 972 8 681 0633ASIA PACIFICChina+86 400 111 9618 India+91 20 4075 2222 Japan+81 47 458 8836 Korea+82 31 716 7070 Singapore+65 6546 8408 Taiwan +886 3758 1000 AMERICASUSA+1 800 848 9800 Brazil+55 11 3952 5000Publication Number: 3601 0096 01© Edwards Limited 2016.

1概述1.1 分类与特点本说明书所列分子泵，按口径不同，从100mm到400mm（对应抽速从110l/s到3500l/s）共5个系列，12种泵。

分子泵一般有两种结构形式，一种是由动静叶列组成的涡轮分子泵，一种是由涡轮级加牵引级构成的复合型分子泵。

复合型分子泵的特点是使得分子泵高压强区的抽速有所提高，另一特点是使得出口耐压得到提高，因此可以适当减小前级泵的规格，可使用户节省投资。

根据分子泵轴承润滑方式不同，分子泵有油润滑、脂润滑两种。

一般情况下，油润滑分子泵需竖直安装（F-100/110可以水平安装），脂润滑分子泵可以任意角度安装。

6.安装6.1 注意事项分子泵不能用于抽除液体或者带有粉尘、固体颗粒的气体；除了耐腐蚀型泵以外，其他任何分子泵不能用于抽除腐蚀性气体，耐腐蚀型泵在抽除腐蚀性气体时，必须给分子泵的保护气体入口连续通惰性保护气体如氮气等，且泵油使用我公司提供的专用耐腐蚀分子泵油。

确认分子泵与电源相配套。

每种泵都只能使用本说明书中规定的与之匹配的电源供电，否则造成的损失，本公司概不负责。

确认安装环境必须满足如下条件：1)泵体表面径向和轴向磁场强度均不得大于3mT(30Gs)；2)环境放射性强度<105rad；3)环境温度为5~40℃；4)空气相对湿度：≤85%；5)电压：220±22V，频率：50±1Hz；6)海拔：≤3000米。

安装前应检查分子泵运输中是否被损坏：打开泵高真空端法兰盖板，戴好手套，拨动涡轮转子，应转动灵活，无异常现象。

若存在异常现象，应及时通知我公司，不得自行处理，否则由此带来损失我公司概不负责。

不允许将分子泵长期置于大气状态下存放，在打开进气口和排气口盲板时，应注意真空卫生要求，严禁杂物、灰尘等落入泵内。

安装环境应符合技术要求和真空卫生要求。

6.2 连接安装6.2.1真空联接分子泵的进气口和排气口法兰采用国际标准见表4分子泵技术数据表,尺寸见分子泵安装简图和分子泵排气口简图。

注意：法兰密封面不得有划痕、刀口不得磕碰。

泵的联接可利用进气口法兰吊装或将泵置于基座平面上，但F-400/4200不建议吊装，若一定要吊装必须用活套法兰（订货时单独订购）固定。

分子泵的进气口法兰通过金属波纹管与系统联接时，分子泵必须固定。

为保护分子泵转子，防止外界物质落入泵内，可在泵口装上防护网，但装入此网后，抽速约降低15％左右。

前级泵与分子泵的联接应采用具有减震效应的金属波纹管，管路上应装有隔断放气阀，作为停机时对前级机械泵放气。

放气阀可选用手动阀或电磁阀。

放气过程的操作请参照停机部分。

为保护泵体真空卫生，防止潮湿，放气时，可通氮气或干燥空气。
