How to Use the Liquid Pump Correctly and Standardized?

1. Strictly implement process operating procedures in accordance with various safety systems.

2. Do not reverse the operation, and do not cut off the liquid.

3. A pump with cooling water cannot be cut off from running.

4. If there is leakage or looseness during operation, remember to stop the car in time for treatment.

Precautions for maintenance safety:

1. Before maintenance, go through the equipment that is allowed to undergo maintenance.

2. Before the equipment is repaired, the power supply needs to be cut off and the "No Movement" sign is hung before maintenance can be repaired.

3. Anyone who needs to perform fire operation at the production site needs to apply for a "fire certificate".

4. Remember to place the maintenance tools and parts for disassembly and cleaning to facilitate installation and use.

5. When entering pits, undercover wells, etc. for maintenance, hazardous gas and oxygen content should be analyzed to avoid poisoning.

Safety precautions for test drive:

1. The test work of the liquid-sludge pump requires someone to command it.

2. Set up obvious test run signs and prohibit unrelated personnel from entering the test run site.

3. After the test run is completed, the operator should close the valve and stop the operation according to the parking procedure, and notify the electrical department to cut off the power.

Notes on use:

1. Can't drive. Check whether the wiring connection is firm and whether the switch contact is tight. If the circuit is open or the contact is poor, calibration should be performed.

2. The motor is overheated. Check whether the wiring and switch are short-circuited, check whether the impeller, impeller cover and motor stator conflict with the rotor, and clear obstacles in time.

3. Lack of liquidity. This is because the elevator is too high, the pipes are too long, and the pipes are bent at right angles. Adjust the head, shorten the pipe, change the curvature of the pipe, check and clean the filter and pipe blockage.

4. Can't absorb water. The reason is that air and water supply pipes accumulate in the pump body. Cleaning method: First increase the water pressure, inject water into the pump body, turn on the power supply, check the oil seal ring of the pump shaft, and replace the new product when the wear is severe.

The above is related to the sub-liquid pump. I hope it will be helpful to you. If you have any other questions, please feel free to consult.
