In daily industrial production, the slurry pump is an indispensable industrial equipment. The slurry pump is widely used. However, during the on-site use of the slurry pump, various faults are inevitable.
For example, when the slurry pump cannot absorb water, how can we solve it? I believe that most users may feel helpless. The following Panshi Pump Industry slurry pump manufacturer teaches you how to troubleshoot and solve the problem. We can follow the steps below to troubleshoot and solve the problem:
Suction pipe or packing seal: Check whether the suction pipe or slurry pump packing seal is leaking. If there is a leak, the leaking part should be blocked to ensure the sealing of the suction pipe and packing.
Joint: Check the connections of the suction pipe, tighten the loose bolts, and eliminate the leak.
Inside the pump body: Check whether there is any abnormal sound inside the slurry pump, which may be caused by air infiltration or impeller damage or impurities. At this time, it is necessary to adjust the pump pool liquid level, check and replace the damaged impeller, and clean the debris in the pump body and impeller.
Suction pipe: Check whether the suction pipe is blocked. The pipe may be blocked due to unclean material discharge during parking or too concentrated medium during startup. At this time, the machine should be stopped and the pipe should be cleaned before starting.
Impeller hole: Check whether the impeller hole is blocked. Long-term pump shutdown or large particles entering the pump may block the water wheel hole, resulting in insufficient centrifugal force. At this time, it is necessary to remove the water wheel inlet pipe and the rear guard plate of the water pump to clean the blocked water wheel hole.
Steering and impeller: Check whether the steering of the slurry pump is correct and whether the impeller is damaged. If the steering is wrong, the motor wiring should be adjusted; if the impeller is damaged, a new impeller should be replaced.
Vibration: If the slurry pump vibrates severely, it may be caused by cavitation, eccentricity of the pump shaft and the motor movement trajectory, or loosening of the foot bolts. At this time, the outlet valve should be adjusted to make the pump operate within the specified performance parameter range, and check whether the foot bolts are loose and tighten them.
Packing gland: If the packing gland is too tight, it may cause the packing to heat up and affect the performance of the pump. At this time, the packing gland bolts should be loosened appropriately to reduce the packing pressure.
Bearing: Check whether the bearing is damaged and whether the grease (oil) is appropriate and clean. If the bearing is damaged, a new bearing should be replaced; if the grease (oil) is insufficient or excessive, or there are debris, the amount should be adjusted or replaced with a new, clean lubricant (oil).
Drive device: Check whether the tightness of the drive belt is appropriate. If it is too tight or too loose, it should be adjusted to the appropriate tension.
To avoid the occurrence of failures such as the slurry pump being unable to absorb water, daily maintenance work must be done in place. Regularly check the operating status of the slurry pump and deal with abnormalities in a timely manner. At the same time, keep the pump body and pipeline clean to avoid clogging by debris.
In summary, solving the problem of the slurry pump being unable to absorb water requires investigation and treatment from multiple aspects. If the above methods cannot solve the problem, it is recommended to contact professional maintenance personnel or manufacturers for further inspection and maintenance.
