First, the purpose of pump maintenance.
Ensure that the pump running status or standby status is always good.
Second, the pump maintenance project.
1. Check the stuffing box
Pumps using packing box seal, we must pay attention to the packing tight, too loose leakage too much impact on performance, in normal times, the amount of leakage should be about sixty drops per minute, dripping for normal, dripping too much for abnormal.
2. Check the mechanical seal
Mechanical seal dripping water is not exposed, if you find the pump seal out of the dripping phenomenon, please replace the mechanical seal.
3.Lubricate the bearings
Check whether the oil discolouration, impurities, if any should be replaced as soon as possible. If you find the bearing sound abnormal, need to replace the bearing
4.Check the oil tank
Check whether the oil tank is short of oil, if short of oil add to the appropriate position.
5.Check the impeller cleaning
The impeller of the water pump flows into the foreign matter, need to check and clean up, keep the impeller impeller smooth. If the impeller is worn out, it will affect the flow and head efficiency, and need to replace the impeller.
6.Check wearing parts
Regular inspection of wearing parts, even if the replacement, so as not to affect the efficiency of the pump.
7. Coupling bolts and rubber gaskets of the coupling should be replaced if they are damaged.
