郑州巴特熔体泵，齿轮泵的拆卸 Disassembly

　　如果对泵作定期维护，应通读并理解本说明，要确保正确的拆卸，应遵守下述要点：

　　1.拆卸时要注意所有部件的位置和方向，以保证组装时正确归位，存放零件的场地应干净整洁。

　　2拆卸时要使用软口台钳夹持泵体。进行维护时，要小心拿放部件，避免坠落及碰撞。因为轻微的划痕或毛刺都会使装配困难，并引起对泵的损坏。

　　3.小心取出密封组件，注意不要损坏密封沟槽和轴，否则泵工作时，可能会导致物料泄漏。然后检查冷却水进出口，确认无堵塞。密封组件是有两个部件并通过紧固螺钉组合在一起的。如有堵塞，可将其拆开，用机械或化学方法进行清洁。

　　4.将端盖板上所有的螺栓松开一圈，然后全部旋松并取出。取下端盖板，并将其放在安全的地方，以防损坏。这时要记住每个轴承上的沟槽对应于泵进口的方位。组装时必须按照原方位装回，否则，当启动时泵会被严重损坏。

　　5.将齿轮轴与轴承从中板中取出，由于泵内留有残余物料黏度，它们有时很难被取出。因此取出时要特别注意，不要敲打或损坏齿或轴承的边角，可用塑料或软铜锤，轻轻敲打，将其取出，不要用铁锤。

　　6.将轴承从齿轮轴上取下，注意不要损坏齿，轴承边角及轴。如果不易拆开，（由于有残留物料黏度），可用塑料或软铜锤敲打轴承使其松动，不可用铁锤。不要用螺丝刀或其它工具将其撬开，因为这容易将齿损坏。要记住所拆下的轴承来自于哪根轴，然后将其放在一旁安全的地方。

　　7.泵被解体以后，所有部件都应仔细检查，确认是否有磨损，裂纹，毛刺及划痕等。端盖板，D型轴承可用600#砂纸打磨，如有毛刺，划痕或其它尖角出现，可用磨石轻轻打磨。计量齿轮，中板及D型轴承之间的关系对保证计量性能是非常重要的，因而打磨时要特别小心，只需将表面抛磨干净，而不能去除金属。在任何情况下，都不能对这些部件进行磨削。

　　If you want to do regular maintenance for the pump, you should read and understand the instruction and ensure the correct disassembly. Observe the following points:

　　1.Notice the position and direction of all parts during disassembly, so as to return the correct position during assembly. Place the parts in a clean and tidy place.

　　2. Hold the pump with soft mouth clamp during disassembly. Take and put the parts carefully during maintenance, avoid falling and colliding. The slightest nick or burr will cause trouble for assembly and damage the pump.

　　3. Remove the seal components carefully, don’t damage seal grooves and axis, otherwise that will cause the material leakage when the pump is working. Check the inlet and outlet of cooling water, ensure there is no jam. Seal components are assembled by two parts through tightening bolts. If there is jam, you can unpack them and clean them by mechanical or chemical method.

　　4. Loosen one circle of all bolts on the cover, then loosen and remove all of them. Remove bottom cover; place it in a safe location. Remember each bearing on the groove corresponds to the inlet direction of the pump. Reinstall them in original location; otherwise the pump will be damaged seriously when you start it.

　　5. Remove the gear axis and bearing from middle plate. It will be difficult for you to remove them owing to the remnants of viscous materials. Don’t knock or damage gear or bearing angel. You can remove them by using plastic or soft copper hammer, but iron hammer is not allowed to be used here.

　　6. Remove the bearing from gear axis; take care of gear, bearing angel and axis. If it’s hard to remove （dueling to the remnants of viscous materials）， you can loosen the bearing by using plastic or soft copper hammer, also iron hammer is forbidden. Don’t pry it with screwdriver or other tools, because that will damage the bearing. Remember which axis do the bearings come from, and then place them in a safe location.

　　7.After breaking up the pump, check all parts and see if there is abrasion, crack, burr, and nick or not. The cover and D shaped bearing can be burnished by 600# sandpaper. If there is burr, nick or other sharp angle, you can burnish them with grindstone. The relationship among metering gear, middle plate and D shaped bearing is important to assure the metering performance, so you should be careful when burnishing them. You should only burnish the surface clean, don’t remove the metal. You can’t grind these parts under any conditions
