Lubrication
Lubrication of bearings
Lubrication position and time intervals see Table 5.1. The lubrication for main bearing should be done during normal operation of centrifuge, fill lubricate until it overflows from lubricate discharge. The reasonable amount of lubricate is to 1/3 of lubricate tank, in case of lacking lubricate, the bearing might be burnt, while in case of over lubricate might cause abnormal heating up.
Lubricating holes of impeller big and small end bearings are respectively on the big and small end covers, and the lubricating work should be done during the centrifuge is stopped. Open the upper cover of collection box and screw off the jack screw, and respectively inject 25g and 86g lubricate into small end and big end with grease gun. When injecting lubricate, symmetry jack screws should be screwed off in order to allowing existing lubricate to discharge.
Lubrication of gear box
After 300 hours of first time running of a new gearbox, lubricate must be changed. Before filling in the new lubricate, the inner chamber of differential mechanism must be clearly drained. Re-lubricate with new lubricant after every 1000-1500 hours operation per above mentioned instructions. Use mesh 100 filter when lubricating. Obstacles like iron scraps adsorbed on the magnetic plug must be cleaned every time when lubricating or re-lubricating. Check the lubricate amount per figure 5.2. Adjust the lubricate hole to 30 degrees to horizontal, when the lubricant is just to overflow, it means lubricating is enough. (Not to fill it totally full).
Lubrication or Feeding Pumps (see operation manual of centrifuge feeding pump)
Before delivered from factory, bearings are already well lubricated, and also differential mechanism and couplings, and passed the 4 hour unload commissioning test. When you start to use of decanter centrifuge or re-start it after a time, please check all the lubricating points and check if there is oil leaking on differential mechanism and couplings. Re-lubricate per conditions.
