How does the screw pump pump oil repair? Today the diaphragm metering pump manufacturer Koo machinery introduces the following repair methods for you.

1. severe vibration of oil pump

Perhaps the electric rotor is unbalance, or the coupling is bad, the bearing is worn and bent; it may also turn some parts loose and broken; maybe because the pipe support is not strong. It can be adjusted, repaired, reinforced and replaced separately.

2. pipe leaking or leakage

The nut can not be screwed tightly when it is installed. If leakage is not serious, smear oil sludge or oil slurry mixed with asphalt oil in the areas where air leakage or oil leakage is possible. Temporary repairs can be coated with wet mud or soft soap. If oil is leaking at the joint, the nut can be tightened with the hand. The oil leakage must be reassembled.

3. filler overheating

Because the packing is too tight, the cooling oil will not enter the packing, or the shaft surface will be damaged. Appropriate measures should be taken to relax the stuffing and seal the pipe. The wear and tear of the packing must be replaced. Before installation, the oil is soaked and loaded in a circle. The incision should be staggered, so that oil leakage can be reduced. After packing the packing in the last lap, press the lid tightly and adjust the tightness when running.

4. oil pump does not suck oil or do not drain oil

The reasons are mostly stuck at the bottom valve, partly silted up in the oil filter, too high oil absorption height or oil absorption and leakage. After checking one by one, they can be treated by repairing the bottom valve, removing the silt, correcting the steering and cleaning the impeller.
