4． 主要结构及工作原理 The main structure and working principle 

电动润滑泵主要由储油器、带连接法兰的泵元件、减速电机、螺旋压油机构及储油容量指示器组成。

A electric lubricating pump is form by grease reservoir, pump flange components, reduction motor, Spiral press grease institutions and grease storage indicator.

 图  4    Drawing 4

减速电机及泵元件固定于连接法兰上，电机驱动偏心轴带动滑叉作直线往复运动，同时带动螺旋压油板及刮油板作顺时针旋转（润滑介质为润滑油时无此结构），经搅动变软的润滑脂均匀地被压到泵元件的吸油口周围。

Reduction motor and pump component fixed in connecting flange, motor driver partiality axis drive slippery fork make linear reciprocating motion, and causes spiral oil board and scrape oil board rotate clockwise(under the condition lubrication medium is oil without the structure ). After stirring the grease is soft ,and be pressed around the grease suction opening.

泵体内有二组活塞，每组由一个主活塞和一个副活塞组成，当一组活塞完成吸油过程时另一组活塞完成压油过程。如图4所示，滑叉到达右极限位置，上组活塞完成吸油过程，下组活塞完成压油过程。滑叉开始向左移动，下组活塞中副活塞在弹簧的作用下关闭出油口，主活塞和副活塞之间形成真空。在移动过程中，当主活塞超过吸油口时，润滑脂在大气压力作用下进入主、副活塞间的空腔内。滑叉移动到左极限位置，下组活塞完成吸油过程。运动过程的同时，上活塞组中的主活塞关闭吸油口，副活塞在压力作用下打开出油口，已吸入油脂在主活塞的作用下从出油口排出，上活塞组完成压油过程。滑叉右移，完成与之相反的另半个工作周期。如此周而复始的循环，二组活塞交替的将润滑剂压出，压出的润滑剂经泵元件连接法兰上的过滤器过滤后供送到系统中。

There are two groups of piston in the pump body, each group have a master piston and a deputy piston. When a group of piston complete suck grease process, another group of piston complete press grease process. See drawing 4, slippery fork to limit position of right ,the above piston group finished the suck grease process, the piston group below finished the press grease process. Slippery start moving to the left, deputy piston of below piston group closed outlet under the action of the spring .It’s vacuum between master piston and deputy piston. In the process of moving, When the master piston over grease suction mouth, grease flow into cavity between master piston and deputy piston under atmospheric pressure. Slippery fork moves to the left limit position ，the piston group below finished the suck grease process, master piston of above piston group closed the grease suction mouth, deputy piston open the outlet, the grease has been inhaled flow out by the action of the master piston, the above group of pistons finished pressing grease . Slippery fork began to move right, complete the opposite half working cycle .Like this, two groups of pistons press the grease alternately, inject into the lubrication system .

5． 安装、调试和使用 Installation, commissioning and use

5.1 润滑泵应垂直安装，布置在环境温度合适，灰尘少，便于调整、检查、维修及补脂的地方。

Pump should be installed vertically , set in the place where environmental temperature is appropriate, dust less ,convenient to adjustment, inspection, maintenance and add grease.

5.2 须使用清洁的润滑剂，含有杂质的润滑剂将会造成润滑泵故障甚至损坏。建议使用加油泵从补脂口加脂，补脂时要防止被污染。保持油脂干净对润滑泵的正常运行，延长润滑泵的使用寿命是至关重要的！

Must use clean lubricant , lubricant Containing impurities will cause lubrication pump failure or even damage , suggest using add-grease pump replenish grease from fat liquoring mouth, prevent polluted. Keep grease clean is very important for lubrication pump normal operation and extension the service life!

5.3 泵在shou次充填润滑脂前，zui好先加注适量的润滑油，以利排除空气。如果条件不允许，也可以直接注入润滑脂，但泵在运行至空气排出后才会有润滑脂排出。

At the first time for the pump filling grease, it’s better filling a moderate amount of lubricating oil , to ruled out air . If the condition is not allowed ，can also injected grease directly ,but the grease will flow out only there is no air.

5.4 调压阀的设定压力可以在0～40MPa范围内调节，调节螺钉旋入，压力升高，旋出则压力降低，使用时不允许超过泵的公称压力（40MPa）。出厂时压力已调定为40MPa。

Setting pressure of governing valve is 0～40MPa,can regulate. Adjustment screws twist into , pressure increases , opposite direction the pressure reducing . It doesn't allow higher than nominal pressure of the pump（40MPa）.

5.5 由于某种原因，泵压力达到50MPa时，安全阀中的保险片会破裂，润滑脂从弯管中溢出，泵压力降为零。更换新的保险片前要查明原因，排除故障。保险片在安装时应凸面向上，只能放置一片。如凸面向下或放置两片，泵会因为压力超过允许值而损坏。

For some reason , pump pressure up to 50 MPa , rupture disc in relief valve wii rupture, the grease flow out from the bend pipe, pump pressure drops to zero .Fond the reason before replacement rupture disc, troubleshooting. Raised face up when install the rupture disc, you must only put one piece. If raised face down or put two piece, pump will over pressure and damage.

5.6 泵出油口处的过滤网应定期清洗，以防止堵塞。

Mesh nearby outlet should be clean regularly, to avoid block .

5.7 减速电机初用三个月时应从减速机排气孔中注入适量的二硫化钼润滑脂，以后每四个月补充一次。

At  the first three months, should inject  molybdenum disulphide grease，every four months a supplement after .

5.8 该系列润滑泵为室内使用型，在室外或环境恶劣的条件下使用时需采取必要的防护措施。

This series of lubrication pumps for indoor use, using outdoor or in harsh environment conditions should be necessary protective measures.

6． 故障的判断及排除方法  Fault judgment and elimination

7． 维修 Maintenance

7.1 调压阀维修（参见图6） Maintenance governing valve (see drawing 6)

拧下调压阀外壳，旋出调压阀芯，清洗干净，观察活塞及活塞孔，如果外表光滑，活塞在孔中滑动自如，则说明调压阀芯没有损坏。如果有明显的划伤，活塞在孔中不能自如滑动，则须更换新的调压阀芯。安装时要注意：O形圈不能有任何损伤，如有损伤要立即更换，安装过程中，注意O形圈不要脱落。

Back off governing valve housing , take out governing valve core , clean it, observe the piston and the piston hole ,if the surface is smooth , piston in the hole sliding freely, governing valve core is not damage. If there is a marked scar, piston in the hole not sliding freely, must replace the governing valve core . When installation should pay attention : O-ring can't have any damage, or replaced immediately , installation process , be sure O-ring not fall off .

7.2 螺旋压油机构维修 Spiral press grease institutions servicing

首先要判断压油机构是否存在故障，判断方法为：停止润滑泵，打开储油桶盖，用手扳动垂直刮油板，如果顺时针可以转动，逆时针不能转动，则说明压油机构没有故障。润滑泵启动时刮油板不转可能是储油器内油脂太少所致，否则说明压油机构有故障。

Determine if the spiral press grease institutions is out of order. Judgment method :stop the pump ,open the cover of the barrel, move vertical grease board by hand, If clockwise rotation, don’t rotation counterclockwise, mean spiral press grease institutions is well. At the time starting pump, scrape oil board not rotation may be the grease is too little , otherwise pressure grease institutions have a fault.

取下储油桶，将压油机构拆下，检查各零部件是否有损坏，转动部分是否卡死。重新安装时，须使泵元件上的柱形销处于离合器摆杆槽内（参见图五）。判断方法同上。

Remove the oil storage tank, remove the oil pressure mechanism, check whether the parts are damaged or not, and whether the rotating part is jammed. When reinstalling, the cylinder pin on the pump element must be in the clutch swing bar (see Figure five). Ditto the method of judgment.

7.3 泵元件维修 Pump components maintenance

松开四只M6×50内六角螺钉（GB70-85），将泵元件整体取下，注意定位销、销套及O形圈不要脱落。清洗干净，检查各零件是否有损坏。如果活塞、活塞孔有划伤或严重磨损，则须更换新的泵元件。安装时注意：1）活塞与活塞孔是选配的，不能搞错；2）滑块带油槽的两面与滑叉槽配合；3）定位销、销套及O形圈不要脱落；4）四只螺钉的紧固力要均匀；5）柱形销须装入离合器摆杆的槽内。

Loosen all four M6 x 50 hex screws （GB70-85），take off the  whole pump components, notice positioning pin, pin set and o-ring don't fall off. Clean them, check the parts for damage. If the piston, piston hole have wounds or serious wear , must replace the pump components. When installation, attention : 1）the piston and piston hole is matching , don’t be mistake , 2) The two sides of slider with oil groove, cooperates with slide fork groove .3）positioning pin, pin set and o-ring not fall off ,4) Four screws stress evenly, 5) Cylindrical pin must be put in the swinging rod slot of clutch.
