Mud pumps are generally used in rural areas as river mud, feces, river water, slurry feed, suction and irrigation, instead of shouldering people, and for drainage and drought resistance, they can also be used for vehicle head, river mud, and fertilizer production. It can also be used as a simple mobile fire-fighting water pump in rural areas, as a clearing pond for fish farming, aeration of fish ponds, etc. It can also be used in municipal, chemical, printing and dyeing, medicine, shipbuilding, casting, food and other industries to pump thick liquid, dirty liquid, paste, flowing sand and flowing sludge in urban rivers, etc. can be used as a coal mine to remove small gravel Fluid. If combined with a high-pressure water pump and a water gun to form a hydraulic mechanical earthwork unit, it can be used as an excavator and transporter for land leveling, rivers, ponds, air defense, underground and other projects. Mud pump failure reasons and troubleshooting
Mud pump failure 1: pump does not absorb water
Reasons: Insufficient water for priming, unable to discharge air in pump, air leakage in suction pipe, large gap between front lining and impeller
Solution: continue pouring water, check the pipeline for air leakage, adjust the gap between the impeller and the front lining
Mud pump failure 2: slow pumping
Cause: The gap between the front lining and the impeller is large, the water outlet pipe cannot seal the air, and the emptying is full
Solution: adjust the gap, adjust the water outlet pipeline, install the vacuum pump
Mud pump failure 3: low outlet pressure and low flow
Reasons: There is air in the pump, the gap between the impeller and the front lining is large, the clutch is not tightly closed, and the impeller or the lining is worn
Solution: empty the pump gas, adjust the gap, adjust the clutch friction plate gap, replace the impeller or liner
Mud pump failure 4: pump vibration
Cause: The pump shaft is not concentric with the diesel engine (or motor), the impeller is unbalanced, and the bearing is damaged
Solution: adjust concentricity, balance test by impeller, replace bearing
Mud pump failure 5: Impeller journal wears fast
Reasons: low head of high-pressure water pump, misalignment of packing, non-concentricity of pump shaft and back cover
Solution: replace the high pressure pump higher than the mud pump head, replace the packing, and adjust the concentricity
Mud pump failure 6: fast pump wear
Reasons: Poor construction environment (large particles), long transmission distance, long water inlet pipeline
Solution: replace the sand field, add afterburner unit, shorten the length of the inlet pipe to reduce cavitation
