The countermeasure of signal alarm of waste water pump

The waste water pump is equipped with five groups of fault sensors and sensors, through the sound and light signal of the side cabinet, the water temperature of the monitor side and the temperature of the motor, the shaft temperature, overload, leakage, When the abnormal situation occurs.Flicker yellow in addition to the lamp with a continuous electric flute surface automatic alarm.Submersible sewage pump into the automatic protection, exit the running state. Faced with this situation, the pump attendant should immediately make the following disposal.

(1) Make a record of the pump number, fault display and pump stop time to report to the running department.

(2) suspension pending array of signs to be amended.

(3) continue to observe the pump stopped.

(4) with the technical staff to analyze the cause of the malfunction.

(5) start the emergency repair plan. Under normal circumstances, the humidity light does not affect the pump operation.For the pump side of the mechanical seal of the oil chamber probe touched the oil lead.Can be in the pump during regular maintenance overhaul the probe, replace the oil chamber solution. Water intrusion is due to the aging of the sealing sleeve of the cable connection chamber, leading to leakage of water in the wiring chamber or damage to the electric field.The reason for the leakage sensor is that the mechanical seal on the motor side is faulty.Water invasion and leakage will cause the water system automatic Stop running. In order to prevent the motor cavity from entering the water, the water should be suspended from the water surface quickly .If the motor water, immediately separated from the body connection, drain water. If the winding insulation is less than 20MΩ, the motor shall be disassembled, and the infrared equipment shall be used for insulation treatment. To ensure that the resistance to ≥ 20MΩ. Start the control cabinet in the air switch is not in place together; fuse insurance burning segment; pump wiring chamber phase line blown. Most likely to cause missing phase operation.Maintenance personnel should identify the point of failure, serious repair.
