Fault Analysis and Treatment of Submersible Sewage Pump
Submersible sewage pump uses advanced sewage treatment technology, so it can achieve a strong sewage treatment capacity, for example, it can effectively through the diameter φ30 ~ φ80 mm of solid particles, so the use of submersible sewage pump The market is very impressive, but in the actual use of the process, it will meet the fault, the occurrence of these faults easily affect the submersible sewage pump work, then the submersible sewage pump fault what? How should these problems be solved? Submersible sewage pump failure analysis and processing 1, submersible pump operation abnormal vibration, instability Failure analysis and treatment: (1) the pump base anchor bolts are not tightened or loose; evenly tighten all anchor bolts; (2) the outlet pipe is not Plus independent support, pipeline vibration affect the pump; independent set of water pump outlet solid support, not to pump the water pipe flange bearing; (3) impeller quality imbalance or even damaged or loose installation; repair or replacement of the impeller 2 , Submersible sewage pump in the operation of the flow often appear insufficient or no water failure Analysis and treatment: (1) the installation of the pump is too high, making the impeller immersion depth is not enough, resulting in reduced pump output; control of the pump installed elevation allowable deviation, not free expand. (2) the pump turns to the contrary; before the pump runs, idly rotate the motor, check the steering to make it consistent with the pump. During the use of the above conditions should be checked whether the power phase sequence change. 3, the submersible pump caused by excessive current Motor overload or over-temperature Fault analysis and processing: (1) working voltage is too low or too high; check the power supply voltage, adjust the voltage transmission. (2) There are moving parts inside the pump rub or impeller friction with the seal; determine the location of friction parts to eliminate the failure. (3) low head, the flow caused by large motor power does not match the characteristics of pumps; adjust the valve to reduce traffic, the motor power and pump to match. Above three kinds of situations are submersible sewage pump more common during the use of the accident, the existence of these problems easily affect the use of submersible sewage pump, so users at work, we must prevent these failures, if unfortunately met, it is right These are dealt with promptly and find a suitable solution as soon as possible.
