Sewage Pump Use Methods And Precautions

1. Before using the pump, carefully check whether the cable is damaged, whether the fastener is loose or falling off, and whether the pump is deformed or damaged during transportation, storage and installation.

2. Measure the same and relative ground insulation resistance of the electric pump motor with a 500V megger. The value should not be lower than 2 megohms. Otherwise, the stator winding of the motor should be dried. The temperature of the drying process must not exceed 120 degrees Celsius.

3. the series of pumps are installed in both fixed and mobile. When using the fixed automatic installation, the chain should be inserted into the two lifting eye screws or the lifting plate in the hoisting plate, respectively (from the pump outlet, the connection should be parallel to the pump outlet). Slide down evenly and slowly along the rail until it is automatically coupled into place. When using mobile installation, first set the hose, and use the chain to penetrate the two lifting rings to lift the electric pump up and down. Be careful not to use the cable as a rope to avoid danger.

4. The direction of rotation after the pump is turned on is counterclockwise from the water inlet. If the pump is reversed, simply adjust any two wires in the cable to the wiring position.

5. The ground wire of the electric pump must be connected in strict accordance with the relevant regulations. In order to ensure personal safety during use, it is strictly forbidden to install people to work or move in the vicinity when the electric pump is running, in case accident occurs due to electric leakage of the electric pump. accident.

6. The electric pump must be equipped with a fully automatic water pump control cabinet without special circumstances. Do not connect the power grid directly or use the knife switch to turn on the power to ensure the normal operation of the electric pump.

7. The electric pump must not be operated under low lift for a long time (usually the head is not lower than 60% of the rated head). It is better to control it within the recommended lift range to prevent the electric pump from overloading and burning the motor.

8. The pump without self-circulating cooling device is strictly prohibited from being exposed to the water surface for a long time to prevent the electric pump from being overheated and damaged.
