1.Stainless steel liquid pump failure: Pump Sheung Shui slow
The reason: the lining plate and the impeller clearance, the outlet pipe can not seal the air, full of empty.
Methods: adjusting clearance, regulating the water outlet pipe, installation of pumping vacuum device.
2.Stainless steel liquid pump failure: the water pressure is small, the flow is small
Reasons: there is air in the pump, the impeller and the front liner clearance, clutch closure is not tight, impeller or liner wear.
Elimination method: empty the pump gas, adjusting the gap, adjusting the clutch friction plate gap, replace the impeller or lining board.
3.Stainless steel liquid pump failure: pump wear fast
Reason: construction environment (particle size) is poor, long-distance transportation distance, water pipeline length.
Method: to replace the battlefield, add afterburner unit, shorten the length of a water inlet pipe to reduce cavitation.
4.Stainless steel liquid pump failure: pump vibration
Reason: pump shaft and diesel engine (or motor) is not concentric, uneven impeller, bearing damage.
Methods: the adjustment of the balance of the impeller, the balance of the test, the replacement of bearings.
5.Stainless steel liquid pump failure: pump does not absorb water
Reason: the filling water is not enough, the air in the pump can not be discharged, the leakage of water absorption pipe, the front liner and the impeller clearance is large.
Methods: to continue filling water, check whether the pipeline leak, the gap between the impeller and the front panel.
6.Stainless steel liquid pump failure: impeller shaft neck wear fast
The reason: high pressure pump head, pump shaft packing low dislocation, and the back cover are not concentric.
Method: to replace the high-pressure pump, corrosion resistance is higher than the liquid pump head, adjusting the concentricity of the replacement of packing
