How to maintain a vacuum preloading submersible pump?

Vacuum preloading submersible pump is a device used to extract liquids from the ground or groundwater level to the ground. It is very suitable for drainage tasks in hydraulic engineering, mining, and industrial fields. In order to maintain the normal operation and good performance of the submersible pump, regular maintenance and upkeep are required. Here are some important matters regarding the maintenance of vacuum preloading submersible pumps.

Follow the operating manual: Before carrying out any maintenance or upkeep, be sure to carefully read and follow the operating manual of the submersible pump. This will help you understand how to operate and maintain the pump correctly, as well as the key points of safe operation.

Regular cleaning of the pump body: The exterior and interior of the pump should be cleaned regularly to prevent blockage and reduce the accumulation of dust, mud, and other particles. Clean the pump body with compressed air or clean water, and regularly inspect the surface of the pump body for corrosion and damage.

Check cables and connectors: Ensure that the cables and connectors are in good condition and not damaged or broken. Regularly check if the cables are securely connected to avoid short circuits or electrical malfunctions.

Check the seal: The seal is a key component that prevents the pump part from entering the water. Regularly inspect and replace the seals of the pump to ensure their integrity and tightness, in order to avoid leakage and overheating of the pump.

Check the motor: Vacuum preloading submersible pumps on the market are usually driven by AC motors. Regularly check if the motor is working properly and there are no abnormal noises, overheating, or other abnormal phenomena. If any problems are found, the motor should be repaired or replaced in a timely manner.

Lubrication: Some submersible pumps require lubrication. Before lubrication, ensure that the pump has stopped working and the power has been unplugged. Lubricant should be added at the correct time and amount to maintain smooth pump operation.

Check and replace the filter: The pump filter is used to block particles and impurities, preventing them from entering the pump section. Regularly check if the filter is blocked or damaged, and replace it in a timely manner. This will ensure the flow rate and effectiveness of the pump.

Regular inspection of water level controllers and protectors: Water level controllers and protectors are crucial for the safe operation of submersible pumps. Regularly inspect and test the functions of the water level controller and protector to ensure their normal operation and promptly issue alarms or stop the pump.

Regular inspection of pipelines and valves: Check whether the inlet and outlet pipelines and valves of the pump are working properly, and repair or replace damaged components in a timely manner. Maintaining unobstructed pipelines and normal operation of valves can improve the efficiency and lifespan of pumps.

Regular inspection of work records: Maintenance personnel should regularly record the working condition of the submersible pump, including operating time, maintenance date, and recorded faults. This helps to identify potential issues and take timely measures for repair and maintenance.
