Failure Friday pump power consumption is too big reasons: 1. packing too tight and heat flow position 2. 3. Turn excessive grazing and the casing has a pump bearing wear 4. 5. shaft bending Solution: 1. 2. appropriate to relax the pressure off a small filler valve opening degree rotation and the casing trim 3. Location 4. Replace the bearings 5. Replace or correcting faults pump vibration increased six reasons: 1 partial clogging impeller impeller breakage 3. 2. Flow too small and the motor shaft misalignment 4. 5. 6. mixed with air bearing damage Cavitation occurs Solution: 1. Removing the impeller 3. Remove foreign 2. Replace slightly open the outlet valve 4. 5. Change the suction point alignment position Improving the suction pipe start, run, stop (a) start: WARNING: To the operator's safety, do not go beyond the pump nameplate operating conditions MD46-30X5 mining multi-stage pump, in order to avoid endangering the safety equipment and operating personnel. To ensure smooth operation and maintenance of pumps and other actions, please refer to the instructions. 1, the pump should be preceded starter plate moving rotor MD46-30X4 mining multi-stage pump, check the rotor is flexible. 2. Check the motor rotation is consistent with the steering pump. 3, close the pump outlet valve, pressure gauge cocks, liquid or vacuum conveying system to exclude air pump suction pipe and in vivo (non-empty start running). 4. Check the tightness of the security situation in the pump and motor bolts and around the pump, the pump is ready to start in the state MD46-30X7 multistage centrifugal pumps, mining multi-stage pump, wear multi-stage centrifugal pumps from the Anguo City-yuan Pump Limited.
