Find slurry pump manufacturer on MIZZTECH, real professional slurry pump research and production enterprises, slurry pump model complete, welcome to inquire procurement!
Now summarized as follows:
First, the slurry pump does not suck water
Occurrence of reasons:
1. suction pipe or packing leakage
2. Steering is not right or impeller damage
3. Suction pipe blockage
Solution:
1. Plug the air leakage part
2. Check the steering and replace the impeller with a new one.
3. Exclude the blockage
Second, the slurry pump shaft power is too large
Occurrence causes:
1. packing gland is too tight, packing heat
2. Pump friction
3. Bearing damage
4. Drive device belt is too tight
5. Pump flow is large
6. High speed and high ratio
7. Motor shaft and pump shaft are not centered or not parallel
Solution:
1. Loosen packing gland bolts
2. Eliminate friction
3. Replace the bearing
4. Adjust the belt
5. Adjust the operating conditions of the pump
6. Adjust the speed
7. Adjust the motor shaft and pump shaft
Third, the pump bearing overheating
Causes:
1. Bearing grease (oil), too much or too little
2. Grease (oil) has debris
3. Bearing damage
Solution:
1. Adjust the grease (oil), to be appropriate
2. Change new grease (oil)
3. Change new bearings
Fourth, the pump bearing life is short
Generate causes:
1. Motor shaft and pump shaft is not centered, or not parallel
2. Shaft bending
3. Friction in the pump or impeller out of balance
4. The bearing enters the foreign matter or the grease quantity is not proper.
5. Bearing assembly is not reasonable
Solution:
1. Adjust the motor shaft and pump shaft
2. Change the shaft
3. Eliminate friction, change new impeller
4. Clean the bearings
5. Reassemble the bearings
Five, the pump packing at the serious leakage
Causes
1. Serious packing wear
2. Serious wear of shaft sleeve
3. Seal water is not clean
Solution:
1. Change new packing
2. Replace the shaft sleeve
3. Clean sealing water
Six, the pump vibration noise
Causes:
1. Bearing damage
2. Impeller imbalance
3. Suction pipe air intake, clogging
4. Uneven flow, pump pumping
Solution:
1. Replace the new bearing
2. Replace the new impeller
3. Eliminate air intake, clean up the blockage
4. Improve the pump feed
