We will mainly beSlurry pumpsThe problems often encountered in the process of use are summarized, and the corresponding solutions are compared with the larger convenient users to query the common faults and solutions of the slurry pump.
It is summarized as follows:
1. The slurry pump does not absorb water.
Cause: Air leakage in the suction pipe or packing area;Misdirection or damage to the impeller;Blockage of suction tubes.
Solution: Block the leaking part;Check the steering and replace the impeller with a new one;Eliminate blockages.
Second, the shaft power is too large.
Causes: The packing gland is too tight, and the packing is hot;Friction is generated in the pump;The bearings are bad;The drive belt is too tight;The pump flow rate is on the high side;The rotational speed is on the high side, and the specific gravity is large;The motor shaft is misaligned or not parallel to the pump shaft.
Solution: Loosen the packing gland bolts;Eliminate friction;Replacement of bearings;Adjust the belt;Adjust the operating condition of the pump;Adjust the rotational speed;Adjust the motor shaft and pump shaft.
3. The bearing is overheated.
Causes: Bearing grease (oil), too much or too little;Grease (oil) has impurities;Bearing damage.
Solution: Adjust the grease (oil) to be appropriate;Change the grease (oil) with a new one;Replace the bearings with new ones.
Fourth, the bearing life is short.
Cause: The motor shaft and the pump shaft are not aligned, or not parallel;Shaft bending;There is friction in the pump or the impeller is out of balance;Foreign matter or improper amount of grease entering the bearing;The bearing assembly is unreasonable.
Solution: Adjust the motor shaft and pump shaft;Shaft change;Eliminate friction and replace the impeller;Cleaning the bearings;Reassemble the bearings.
Fifth, the leakage of the packing is serious.
Cause: Severe wear of the filler;Severe wear of the bushing;The seal water is not clean.
Solution: Replace the filler;Shaft sleeve change;Replace with clean seal water.
6. The pump vibrates and makes noise.
Cause: Bearing damage;The impeller is unbalanced;Suction tube intake, blocked;The flow is uneven and the pump is evacuated.
Solution: Replace the bearing;Replace the impeller;Eliminate air intake and clean up blockages;Improved pump feeding.
