Horizontal double-suction pump _ how to do a good job of regular maintenance of the pump?
First, the purpose of pump maintenance.
Ensure that the pump running status or standby status is always good.
Second, the pump maintenance program.
1. Check the stuffing box
Pumps using packing box seal, be sure to pay attention to the tightness of the packing, too loose leakage is too much impact on performance, in normal times, the leakage should be about sixty drops per minute, drip for normal, drip too much for abnormal.
2. Check the mechanical seal
Mechanical seal dripping water is not exposed, such as found in the pump seal out of the phenomenon of dripping, please replace the mechanical seal.
3.Lubricate the bearings
Check whether the oil is discolored, there are impurities, such as 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 lack of oil, if lack of oil to add to the appropriate position.
5.Check impeller cleaning
Water pump impeller inflow of foreign matter, need to check and clean, 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 the 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 should be replaced if damaged.
8. Tighten the machine screws and do rust treatment.
Third, the maintenance of the motor
1, the appearance of the inspection should be clean, intact nameplate, grounding wire is well connected.
2, remove the motor junction box wire connection piece, with 500V megohm meter test motor winding phase and phase, relative to the ground insulation resistance value should not be less than 0.5 megohm.
3, motor junction box three-phase wires and connecting pieces should be firm and tight.
