Summary：This high and low pressure thin oil lubritory is used for the principal axletree of the ball mill. Each ball mill equips such a lubritory. The high and low pressure oil lubritory is made up of high and low pressure oil supply systems. The high-pressure oil supply system provides static pressure support to the principal axletree at both ends of the ball mill separately while the low one is split in two after effusing the oil to provide the dynamic pressure lubrication.The high pressure oil supply system: the ball mill has to transport the high pressure oil before starting or stopping so that the principal axletree of it floats and the oil film at a certain thickness is formed between the principal axletree and the spherical tile. With the aim to debase the starting moment, otherwise the tile kilning accident, caused by the direct tangency of the principal axletree and the spherical tile, will occur when the ball mill stops if the rotate speed of it is too low to form the required oil filmThe low pressure oil supply system: when the ball mill runs normally, the dynamic pressure lubrication will form between the principal axletree and the spherical tile, which debases the wearing, reduces the power consumption, carries away the generating heat, refrigerates the principal axletree and lengthens the service life of the equipments.The operating environment of this lubritory requires indoor, dry air, no damp, lustration, no noxious gases, no explosivity gases, no aggressive gases wrecking metal and insulation, no conducting dust, no more than 1500 meters altitude and around the 5-40 Celsius degrees.2.

Operation Principle：The high and low pressure thin oil lubritory is mainly made of oil tank, high-pressure oil pump, high-pressure relief valve, high backpressure valve, electromagnetical diversion valve, high-pressure valve; low-pressure oil pump, low-pressure safety valve, low backpressure valve, oil filter, cooler; pressure controller, humidity controller, electrical crunode thermometer, pressure instrument, pipeline, low-pressure valve and so on.The low-pressure oil pump electromotor has to be started first when the ball mill starts or stops. Then the low-pressure oil pump will draw out the dubbing from the oil tank through diversion valve, oil filter, cooler, low-pressure valve, intermediate piping and flow control device sending to the oil site of the principal axletree at both ends of the ball mill. At the same time, the dubbing drawn out is sent to the input port of the high-pressure oil pump. After the low oil pressure achieves the normal value, the high-pressure oil pump electromotor has to be started. Then the high-pressure oil pump will draw out the high-pressure dubbing changed from the low-pressure one through high backpressure valve and high-pressure valve to the principal axletree of the ball mill. Effusing from the oil site, the lubrication will pass through the oil return port at the principal axletree of the ball mill, the intermediate piping, the oil return filter setted in the oil tank and reflow the oil tank after filtration.This cycle process will ensure the lubricating system work normally.The over-oil-pressure protection to the high and low pressure of the system isfinished by the relief valve and safety valve. When the oil pressure exceeds the setup oil pressure value at the working condition, the relief valve and safety valve will automatically open to step down the pressure in order to realize the overload protection.The operating pressure value of the low pressure system depends on the factors of the opening level of the oil site, the difference of elevation between the lubritory outlet and the oil site, the length of pipeline, the quantity of elbow, and the valve opening and so on.The operating pressure value of the high pressure system is mainly determined by the load and depends on the weight of the ball mill itself and the load, the clearance between the spherical tile and the journal of the principal axletree. The other influential factors are the same as that of the low pressure system.The drain contamination valve on the lubritory is used for quickly eliminating the waste oil which reaches the renewal date and can’t be used ever in the oil tank.Two high-pressure gauges are used for directly observing the oil pressure of the high pressure system. Four high-pressure controllers are used for controlling the oil pressure of the high pressure system. Two low-pressure gauges are used for directly observing the maximum oil temperature warning of low-pressure oilout.One electrical crunode thermometer is used for high oil temperature warning in the oil tank. Two temperature controllers are used for controlling the operation of the electrical heater and electromagnetical gate valve.The oil tank of the lubritory is enclosed type. The supercharged air cleanser setted on it will meet the working condition that the altitude difference from the oilout to the oil site is less than 6.0 meters.If some accident occurs and the oil supply has to be stopped to fix, the main generating room or the designing institute don’t allow the U type of pipeline for connection when doing the design of tubing and the users’construction. The connected caliber should be greater than or equal to that of oilout. The valve on one side of the oil tank must be closed when fixing in order to ensure the maintenance work under no oil condition.4. Structural Features：4.1 The lubritory has three high-pressure oil pumps, the two of which work at thesame time and supply the oil to one principal axletree of the ball mill separately while the rest one is for standby. It also has two low-pressure oil pumps, one of which is for working and the other one is for standby too.4.2 The oil filter of the low pressure system is setted on the front of columnwisecooler. The filtration effects will be good if filtrating first and then cooling. (The oil’s through capacity represented in the oil filter has something to do with the viscosity temperature characteristic. When the temperature is high, the oil viscosity is low and the through capacity is great. Contrariwise, the through capacity is low.)4.3 The oil filter of the low pressure system adopts twin-cylinder network-pattern oilfilter and one filter element is for working while the other one is for standby.When the working filter element is jammed and warning, we should let the standby one to work by moving the switching hand onto it. The jammed filter element can be taken out to cleanout or replacement when doing the normal maintaining but not to stop the host.4.4 The oil filter of the low pressure system adopts the GLC type of shell-and tube oilcooler, which adopts finned tube. The water side channel adopts double monitor framework, which puts up the advanced technology and distinct heat exchange effect.4.5 The oil return magnetism filter is setted at the back of the oil return port in the oiltank, which will adsorb the scrap iron from the oil return and filter the oil return.4.6 The meter is to be setted on the pipeline at the observed-tend position, whichlooks beautiful.4.7 A by-path valve connected to the oil return tank is setted at the outlet piping on thelow pressure system, which is used for the low-pressure oilout distributary and filtering circularly.4.8 The lubritory has the electric cabinet which can be ordered with the lubritory bythe users if required. And the electric cabinet has its individual operating specification.5. Main Control Function：5.1 Oil Pressure ControlEach high-pressure oilout has two pressure controllers and four ones in total. The pressure controller is used for monitoring the oil pressure and separately controlling the standby oil pump electromotor whether to be electrified, over high-pressure warning and the starting of the ball mill.The first group of the second high-pressure oilout port：After the high-pressure oil pump works, when the oil pressure achieves to the first setting value (the setting value is determined by the actual oil pressure when the ball mill is lifted.) of the pressure controller (the range of it is 2.5-25MPa), the system will enter the normal operating condition. The indicator light shows the high pressure normally. After the pressure stabilizes, the ball mill can be started.When the oil pressure can’t achieve the setting value, the sound-light warning signature will represent that the high-pressure oil-pressure is low, which is used the switching difference of the pressure controller. The electromagnetical diversion valve will be electrified first and then will the standby high-pressure oil pump after 1-2s. The operating high-pressure pump electromotor is cut. When the oil pressure is achieving or over the normal value, the ball mill can be started. If the oil pressure can’t achieve the normal value yet, the electronic control cabinet will send the sound-light warning signature representing that the high pressure is failure and the ball mill can’t be started.When the oil pressure achieves the second setting value (the range of it is4.0-40MPa) of the pressure controller, the electronic control cabinet will send thesound-light warning signature representing that high-pressure oil-pressure is high or the ball mill is forced to stop.The second group of the first high-pressure oilout port：After the high-pressure oil pump works, when the oil pressure achieves to the first setting value (the setting value is determined by the actual oil pressure when the ball mill is lifted.) of the pressure controller (the range of it is 2.5-25MPa), the system will enter the normal operating condition. The indicator light shows the high pressure normally. After the pressure stabilizes, the ball mill can be started. When the oil pressure can’t achieve the setting value, the indicator light will send the sound-light warning signature representing that high-pressure oil-pressure is low, which is used the switching difference of the pressure controller. The electromagnetical diversion valve will be cut first and then the standby high-pressure oil pump will be electrified after 1-2s. The operating high-pressure pump electromotor is cut. When the oil pressure is achieving or over the normal value, the ball mill can be started. If the oil pressure can’t achieve the normal value yet, the electronic control cabinet will send the sound-light warning signature representing that the high pressure is failure and the ball mill can’t be started.When the oil pressure achieves the second setting value (the range of it is 4.0-40MPa) of the pressure controller, the electronic control cabinet will send the sound-light warning signature representing that high-pressure oil-pressure is high or the ball mill is forced to stop.When the ball mill is started normally and after a period of time delay, the high pressure system will stop automatically.When the ball mill stops, the high-pressure oil supply system will start automatically at the same time. When the temperature of the principal axletree of the ball mill falls to the room temperature or achieves to the appropriate one, the high-pressure oil supply system should stop first and then will the low-pressure oil supply system.When the ball mill is in the slow-drive operation, high and low pressure oil supply system should always be in the normal operation until achieving the meet of the operator. The high-pressure oil supply system will be stopped first and then will the low-pressure oil supply system.Generally, in the normal stop situation, the high and low pressure system should last working for another 15-30min and then stop supplying oil.The low-pressure oil supply system has two pressure controllers which are used for monitoring the oil pressure of the oilout. The oil pressure of the oilout reduces to the first setting value (the recommendation value is 0.08-0.15MPa) of the pressure controller (the range of it is 0.02-0.2MPa) in the operation, the sound-light warning signature will represent that the low-pressure oil-pressure is low and the standby oil pump at the same time will be started and the operating one will be stopped. When the pressure of the system renews the normal value, that sound-light warning signature should be cancelled by use of the switching difference of the pressure controller. As the standby oil pump is in the operationand the oil pressure still can’t achieve the required value, the sound-light warning signature will represent that low-pressure oil-pressure is failure and the ball mill will be stopped at the same time.When the pressure is achieving or over the setting value (the recommendation value is 0.6MPa) of the other pressure controller (the range of it is 0.05-0.8MPa), the sound-light warning signature will represent that low pressure is high or the ball mill will be stopped.5.2 Flow ControlOn the oil supply pipeline close to the principal axletree at both ends in the low-pressure oil supply system, each flow switch is set actinically which is used for monitoring the flow change in the pipeline. When the flow in the pipeline reduces to its setting value, the sound-light warning signature will represent that the oil flow is cut or the ball mill will be stopped.5.3 Oil Temperature ControlThe oil tank has two temperature controllers and one electrical crunode thermometer which are used for monitoring the temperature change in the oil tank and controlling the electrical heater and oil valve. When the oil temperature in the oil tank is under the setting value (the recommendation value is 10 Celsius degrees) of the first temperature controller (the range of it is 10-40 Celsius degrees), the electrical heater will be electrified automatically and take the operation of heating dubbing, while the oil pump for operating can’t be started.When the oil temperature is higher the setting value (above the 10 Celsius degrees and the switching difference is 3-5 Celsius degrees), the electrical heater will be cut automatically and the oil pump for operating will be allowed to start.The electrical heater can be also controlled electrified and cut manually on the control cabinet.The other temperature controller’s temperature probe is set nearby the high-pressure oil pump. When the oil temperature here achieves to the setting value, the electromagnetical gate valve used for controlling the water intake of the cooler will be electrified and opened automatically. The cooling water enters into the cooler. When the oil temperature here is under the setting value, the electromagnetical gate valve will be cut and closed automatically. The cooling water can’t enter into the cooler.The one electrical crunode thermometer on the oil tank is used for monitoring the oil temperature in the oil tank. When the temperature in the oil tank achieves to the maximum setting value, the sound-light warning signature will represent that the oil temperature is high in the oil tank and the corresponding indicator light on the control cabinet will show it.An electrical crunode thermometer is set on the low-pressure oilout. When the oil temperature achieves to the maximum setting value, the sound-light warning signature will represent that the oil temperature is over-high or the ball mill is forced to stop.5.4 Liquid Level ControlThe oil tank has a liquid level controller which is used for monitoring the liquid level in the oil tank. When the liquid level reaches to the maximum level, there isa light represented it. When the liquid reaches to the minimum level, thesound-light warning signature will represent that the liquid level in the oil tank is low.5.5 The Control to the Differential Pressure of Oil FilterThere are two differential-pressure switches on the twin-cylinder network-pattern oil filter. When the differential pressure between the filter’s oilin and oilout is over the setting value, the sound-light warning signature will represent that the filter element is jammed. We should let the standby one to work manually. The jammed filter element should be cleaned out or replaced in time.6. Debug and Operating Regulations：The debug to the lubricating system should be affirmed by the engineering departments such as civil engineering, machinery, electricity, heat, instrument and safetyguard that the qualifications of the trial run is prepared and then can be carried. Make sure that the connection to the electricity and heat instrument is absolutely right. The system to supply cooling water can work normally. The connection to the intermediate piping between the ball mill and the lubritory should be finished, cleaned out and achieve the standard requirement.Debug is to regulate the operating oil-pressure to the normal operation range and to adjust out the setting values of every control elements.6.1 The Operation before DebugCharging up the lubrication：The ordered lubrication will be filled by the oil filter vehicle from the lubrication hole on the oil tank into the oil tank at the maximum liquid level. The oil filter vehicle can repeat filtering the lubrication and examine the cleanliness of the lubrication. Indeed, the oil filter vehicle can keep on filtering for 60min, so there will be no solid pollutant viewed on the oil filter and the oil filter vehicle will examine whether the cleanliness of the dubbing has reached the standard requirement.Open the stopcock on the cover board of the oil tank. Let the top of the oil tank connect to the atmosphere. When opening the lubritory for the first time and there is lubrication flowed from the oil site to the oil tank, and then the lubritory can be closed. The liquid level in the oil tank will fall down after starting the lubritory at the first time, so the oil should be added to the required maximum level in time 6.2 The Debug to the Oil Pressure Control Value：The high and low pressure oil pumps are operating normally. The high and low pressure oil-pressure should operate in the normal range by regulating the relief valve and safety valve which are adjusted well before leaving the factory.According to the operating pressure, the setting value of the pressure controllerwill be adjusted on the appropriate position. The detailed elements are as below：There are two setting value of the high-pressure pressure controller (the range of it is 2.5-25MPa). Generally, it is the actual oil-pressure value when the ball mill is lifted.There are two setting value of the high-pressure pressure controller (the range of it is 4.0-40MPa).The setting value of the low-pressure pressure controller (the range of it is0.02-0.2MPa) is 0.2MPa. (It is generally a little lower the normal operatingpressure.)The setting value of the low-pressure pressure controller (the range of it is0.05-0.8MPa) is 0.6MPa.6.3 The Debug to the Temperature Control Value：The setting value of the temperature controller and the electrical crunode thermometer should be adjusted on the appropriate position. The detailed setting values are as below：The setting value of the temperature controller (the range of it is 10-40 Celsius degrees) is 10 Celsius degrees. The differential value of it is 3-5 Celsius degrees.The setting value of the temperature controller (the range of it is 40-80 Celsius degrees) is 10 Celsius degrees. The differential value of it is 3-5 Celsius degrees.The setting value of the electrical crunode thermometer on the oil tank：The minimum value is 10 Celsius degrees and the maximum one is 55 Celsius degrees.The setting value of the electrical crunode thermometer on the low-pressure oilout：The minimum value is 10 Celsius degrees and the maximum one is 60 Celsius degrees.6.4 Adjustment Method：The adjustment to the electrical crunode thermometer：Insert the small key or screwdriver on the electrical crunode thermometer to the dial hole in the middle.Dial the driving lever in the meter to make the upper or lower pointer at the required value.The adjustment to the temperature controller：Unbolt the lock nut on the regulating lever of the setting value at the left-upside. Use screwdriver to rotate the regulating lever. Make the pointer at the temperature setting value required to be controlled. Then screw down the lock nut. Rotate the switching differential knob to make some value between one and three aiming at the red dot in the middle, which is to get the required switching differential value.Notice：Don’t allow to rotate the switching differential knob. The lock nut on the regulating lever of the setting value at the left-upside must be screwed down, because any looseness will cause the setting value changed and affect the control function.The adjustment to the low-pressure pressure controller：Connect one end of the wire to the plug, while the other end is connected to the multimeter. Open the oil pump electromotor and keep the oil pressure at 0.15/0.6MPa. Loose the lock nutof the pressure controller. Use the 5mm socket head screw spanner to rotate clockwise the setting value in order to adjust the hexagon groove. The setting value is from small to big until the contact is switch here. Screw down the lock screw. The oil pressure of the system will change around there values. Examine whether the switching difference of the contact will be at some value when the oil pressure reduces. The value is to be set.The adjustment to the high-pressure pressure controller：Connect one end of the wire to the plug, while the other end is connected to the multimeter. Open the oil pump electromotor and keep the oil pressure at ……. Loose the lock nut of the pressure controller. Use the 5mm socket head screw spanner to rotate clockwise the setting value in order to adjust the hexagon groove. The setting value is from small to big until the contact is switch here.

The value is to be set.Notice：Don’t be allowed to loose the lock screw which is screwed down, because any looseness will cause the setting value changed and affect the control function.6.5 The debug process should be followed as below：The oil pressure should be kept above 10 Celsius degrees. Switch the reversing handle of the twin-cylinder network-pattern oil filter to one of the filter elements.Debug the low-pressure system：Shut the discharge hole and oilout valve. Open the switches of the other valves and pressure gauge. Turn each shaft coupling set on the electromotor pump manually separately. No emphraxis feeling. Inch examination. The turning of the electromotor should be right.Open two low-pressure oil pump electromotor separately. Shut the by-path valve on the exit piping slowly. Observe the two pressure gauges that represent the oil pressure climbing slowly. When the valve is shut totally, the oil pressure should be kept at the 0.6MPa which is adjusted by safety valve. Run for 10min and the low-pressure oil pump electromotor should be with no exceptional sound. No oil leaks and other phenomenon on each jointing and interface.Open the oilout valve. The dubbing through the intermediate piping flows into each oil site of the ball mill and back to the oil tank. Observe the two pressure gauges that represent the oil pressure falling correspondingly and keep at a certain value which is the normal operating oil-pressure (Generally, it is 0.2-0.4MPa.).The low-pressure system enters into the normal operating situation at this time.Debug the high-pressure system：(Now the low-pressure should be in the normal operating situation, otherwise the high-pressure oil pump will be broken.)Shut the oilout valve.

No one and two high-pressure oil pump electromotor is electrified. Observe the two high-pressure pressure gauge. The oil pressure will ascend and fall back at a steady value which is the normal operating oil-pressure (Generally, it is at the range of 6.0-20.2MPa.). Run for 10min and use the meter to measure the lifted value of the principal axletree at the ball mill. The high-pressure system enters into the normal operating situation at this time.Debug the standby high-pressure oil pump：(Now the low-pressure should be in the normal operating situation, otherwise the high-pressure oil pump will be broken.)No. 3 high-pressure oil pump electromotor is electrified while No. 1 is cut.

1．用途XYZ200-L立式稀油站是北京电力设备总厂设计制造的，为ZGM95型磨煤机用SXJ140型立式螺伞-行星减速机配套的专用润滑装置，用于润滑减速机中的齿轮和轴承，起到润滑、冷却和清洗的作用。

2．工作原理稀油站在正常工作时，电机螺杆泵将润滑油从磨煤机减速机下箱内吸出，送入加热器，经管路进入双室过滤器的一个滤筒，再沿管路进入冷却器，然后被送到各个润滑点，润滑油经过润滑部位后汇集于减速机下箱，再经电机螺杆泵吸出，如此循环往复，使润滑油在系统中循环，确保系统各部位的正常润滑。

3．结构特点XYZ200-L立式稀油站由电机螺杆泵、电加热器、双室过滤器、冷却器以及阀门、管道、仪表和底座等组成。

所有零部件均安装在底座上组成整体式结构，稀油站无自带油箱，减速机下箱体就作为稀油站的油箱。

各部分的结构特征如下：3.1电机及三螺杆泵：立式，配双速电机，带安全阀。

驱动采用YD160M-8/4 V1型双速电动机，其功率为5.0/7.5kW，对应转速为720/1450 r/min。

若稀油站启动时油温<25℃时，先令电机720r/min运转，直到油温达到28℃时，再改用1450r/min运转。

油泵上装有对油泵和系统起过载保护作用的安全阀，阀的调节压力为0.63MPa，可保证安全运行。

3.2电加热器：带纵向折流。

纵向折流板将加热管分隔为三个区间，油和加热管间的相对流速增加，可避免因油流死角导致的油温过高区；加热管温度均衡减少了结炭现象；同时采用了能放尽空气的放气结构，保证油加热管温度最高的上部能浸入油液中；这些都提高了加热效率和延长了加热管的使用寿命，同时也减少了顶罩部分的温升，并且油液不易氧化变质，延长了油液的使用寿命。

3.3双室过滤器：采用纵向导流和上下磁过滤结构，带三位六通换向阀。

油液由换向阀进入过滤器中部后，由导向套引入下部，先均匀地经过下部磁过滤装置并由下而上均衡地通过滤网，再同样均衡地流过上部磁过滤装置，最后经换向阀进入下一个循环装置。
