Eight Points For Attention in Sewage Lift Pump Operation

Eight points for attention in sewage lift pump operation:

1. Before using the sewage lifting pump, carefully check whether the cable is damaged, whether the fasteners are loose or fall off, and whether the pump is deformed or damaged in the process of transportation, storage and installation.

2. Use 500V megohm meter to measure the insulation resistance between the same and relative ground of the electric pump motor. The value should not be less than 2 megohm, otherwise the stator windings should be dried, and the drying temperature should not exceed 120℃.

3. sewage lifting pump installation has two kinds of fixed and mobile. When the fixed automatic installation is used, the chain cable should be respectively inserted into the two ring screws or the lifting plate parallel to the pump outlet, the link should be parallel to the pump outlet. Slide evenly and slowly along the guide rail until the automatic coupling is in place. When the mobile installation is adopted, the hose will be set well first, and the chain cable will be inserted into the two rings to lift the pump up and down. Pay attention to the cable can not be used as a rope to avoid danger.

Operation precautions of sewage lift pump

4. The rotation direction of the sewage lifting pump after the pump is connected from the water inlet is anticlockwise rotation. If the pump is reversed, you only need to switch any two wires in the cable to the wiring position.

5. The electric pump housing ground wire must be strictly in accordance with the relevant regulations, in order to ensure the use of personal safety, in the operation of the electric pump, is strictly prohibited in the vicinity of the installation, people do? ~ or move, in case of electric pump leakage and accidents.

6. The electric pump must be equipped with automatic water pump control cabinet in no special circumstances, do not directly hang the power grid or use the knife switch to switch on the power, to ensure the normal operation of the electric pump.

7. The electric pump shall not be run in the state of low head for a long time (generally the head shall not be less than 60% of the rated head), and the recommended head range shall be controlled in order to prevent the electric pump from burning out the motor due to overload.

8. The pump without self-circulating cooling device is strictly prohibited from long-term operation above the water surface as a whole, to prevent the electric pump from overheating and damage.
