(10) multi-stage pump to stop the use of multi-stage centrifugal pump, turn off the valve, pressure gauge, and then stop the motor. (11) multi-stage pump in the first month of work, replacement of oil after 100 hours, after every 500 hours and oil change once. (12) regularly adjusted packing gland, packing the room to ensure the normal drip (with a drip out appropriate). (13) periodically check the wear sleeve, wear large should be promptly replaced. (14) multi-stage pump used in the winter season, parking multistage centrifugal cdlf412, the lower pump drain plug unscrew the media put the net. Prevent cracking. (15) multi-stage multi-stage centrifugal pump blocking long-term disabled, you need to pump all apart, dry water, the moving parts and the junction coated with grease installed, properly preserved. 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 D6-25x8 horizontal multistage centrifugal pump wear mine D6-25 * 8 centrifugal pump manufacturers by Anguo City Pump Co., Ltd.
