What should I do if a sudden malfunction occurs while the mud pump is working?

1. Reason for pump not absorbing water

(1) Insufficient water injection and inability to discharge air from the pump

(2) Air leakage from the suction pipe

(3) Large clearance between the front lining plate and the impeller, etc.

Solution:

(1) Continue to inject water for diversion

(2) Check for air leakage in the pipeline

(3) Adjusting the clearance between the impeller and the front lining plate

2. Reasons for slow water feeding on the pump

(1) Large clearance between front lining plate and impeller

(2) The water outlet pipeline cannot seal the air or empty it completely.

Solution:

By adjusting the gap, adjusting the water outlet pipeline, and installing a vacuum pumping device

3. Reasons for low effluent flow

(1) There is air inside the pump

(2) Large clearance between impeller and front lining plate

(3) Clutch not closing tightly

(4) Worn impeller or lining plate

Solution:

(1) Empty the gas inside the pump

(2) Adjusting the clearance

(3) Adjusting the clearance of the clutch friction plate

(4) Replace the impeller or lining plate

4. Causes of water pump vibration

(1) The pump shaft is not concentric with the diesel engine

(2) Impeller imbalance

(3) Bearing damage

Solution

(1) Adjusting concentricity

(2) Impeller balance test

(2) Replacing bearings

5. Pump wear is fast

(1) Poor construction environment

(2) Large particle size

(3) Long conveying distance

(4) Long inlet pipeline

Solution

(1) Replace the battlefield

(2) Adding an afterburner unit

(3) Shorten the length of the inlet pipe to reduce cavitation
