What are the precautions for using vacuum preloaded submersible pumps?

Vacuum preloading submersible pump is a device used for drainage, pumping water, and pumping oil, which has the following characteristics: compact structure, small volume, light weight, and convenient use. When using a vacuum preloading submersible pump, the following precautions should be taken:

The selection of installation location for the vacuum preloading submersible pump must be on a reliable foundation, with sufficient clearance between the pump body and pipeline to avoid vibration transmission and increased noise. In addition, it is necessary to have abundant water sources to avoid insufficient or polluted water sources that may affect the normal operation of submersible pumps.

Before using the vacuum preloading submersible pump, it is necessary to read the relevant product manual and master the correct operating method. Before starting the submersible pump, the pump outlet gate valve should be closed first, and then the pump should be immersed in water, ensuring that there is sufficient water inside the pump. After starting the submersible pump, gradually open the pump outlet gate valve and pay attention to monitoring the readings of the pressure gauge and thermometer to ensure the normal working process of the submersible pump.

After using the vacuum preloading submersible pump for a period of time, maintenance and upkeep must be carried out to maintain its normal working condition. Regularly clean the submersible pump, remove impurities from the pump body and inside the pump, and prevent impurities from blocking the pump body. Secondly, it is necessary to check the wear of the sealing device and motor parts, and replace damaged parts if necessary. In addition, it is necessary to regularly check the grounding of cable connectors and equipment to ensure safe use of submersible pumps.

The vacuum preloading submersible pump can be used indoors or outdoors, but attention should be paid to the impact of environmental factors on the submersible pump during use. If installed outdoors, it is necessary to choose equipment with good waterproof performance and ensure that the power lines and circuit boards have good insulation performance. In addition, during operation, the submersible pump should be avoided from direct sunlight or rain to avoid affecting the service life and working efficiency of the equipment.

During the use of the vacuum preloading submersible pump, attention should be paid to safety protection to avoid accidents. When operating, it is important to remain clear and focused, and it is strictly prohibited to operate the submersible pump under the influence of alcohol. At the same time, pay attention to the grounding issue of the power line to ensure the safe operation of the equipment. When abnormal operation or malfunction of the submersible pump is found, it should be stopped immediately and after-sales service personnel should be contacted for repair in a timely manner.
