Screw pump For the repair of oil pumping problems, the following repair methods are available for the oil drainage problems found during use:
Severe vibration of oil pump
Perhaps the rotor of the motor is out of balance, or the connection is poor, resulting in wear and bending of the bearing; It can also loosen and crack some parts; It may be due to unstable pipe support and other reasons. It can be solved through adjustment, repair, reinforcement, replacement, etc.
Oil or gas leakage of pipeline
When installing IMO screw pump If the screw cap is not tightened firmly, if there is no big leakage, you can use oil sludge or oil sludge mixed with asphalt oil at the place of air leakage or oil leakage. For temporary repair, you can use wet mud or soft soap. If there is oil leakage on the joint, you can tighten the screw cap by hand. If there is a big leak, it must be reinstalled.

Packing overheating
The main reason is that the sealing gasket of the screw pump is too tight, which causes the cooling oil cannot enter the sealing ring, or the shaft surface is damaged. Appropriate loose packing can be selected to clear the blockage of sealed pipe. Must be replaced with new packing. Before installing the screw pump, first soak the oil, then install it circle by circle, and stagger the cuts to reduce oil leakage. When the last ring of packing is loaded, it shall be fixed and its tightness shall be adjusted during operation.
Oil pump does not suck or drain oil
The main reasons for this are: the bottom valve is stuck, the oil filter is blocked, the oil suction is too large, the oil suction is too large, the oil pump leaks air, or the impeller is blocked due to improper direction. After checking one by one, the following measures can be taken: repair the bottom valve, remove the sludge, correct the steering, and clean the impeller.
