How to choose suitable accessories for vacuum preloading submersible pumps?

Choosing appropriate accessories is crucial for the performance and service life of vacuum preloaded submersible pumps. Below, we will introduce in 1000 words how to choose the appropriate accessories.

We need to understand the basic principle and working mode of vacuum preloading submersible pumps. A vacuum preloading submersible pump is a type of pump that draws back and discharges the pumped liquid. It extracts the liquid into the pump body through the formation of negative pressure, and then discharges the liquid through the rotation of the impeller. Due to the need to generate negative pressure during its operation, the selection of accessories needs to consider factors such as sealing performance, material corrosion resistance, high temperature resistance, and degree of wear.

For vacuum preloaded submersible pumps, sealing performance is crucial. A good sealing system can prevent the liquid inside the pump from leaking out, thereby ensuring the normal operation of the pump. Therefore, when choosing accessories, we should choose materials and structures with good sealing performance. In general, sealing components are made of corrosion-resistant and wear-resistant materials, such as rubber, polytetrafluoroethylene, etc. At the same time, attention should also be paid to the machining accuracy and installation process of the sealing components to ensure their normal operation.

Secondly, the corrosion resistance of the accessory material is also one of the important factors to consider in the selection. The liquids that submersible pumps need to handle may have different corrosive properties, such as acidic or alkaline liquids, liquids containing chlorides or other organic compounds, etc. Therefore, we need to choose materials with corrosion resistance to manufacture accessories. Common corrosion-resistant materials include stainless steel, corrosion-resistant plastics, etc. Choosing appropriate materials based on the corrosive properties of liquids can effectively extend the service life of accessories.

In addition, high temperature resistance is also one of the factors that needs to be considered. Due to the frictional heat generated during the operation of submersible pumps, accessories need to have certain high-temperature resistance performance. Generally speaking, selecting materials with high temperature resistance, such as high-temperature alloys, ceramics, etc., can prevent deformation or melting of accessories in high-temperature environments, ensuring the normal operation of the pump.

Considering that submersible pumps may experience certain wear and tear during operation, we should also choose accessories with wear resistance performance. Generally speaking, choosing materials with good wear resistance, such as engineering plastics, wear-resistant casting materials, etc., can effectively extend the service life of accessories. In addition, attention should also be paid to the maintenance and upkeep of accessories during use, and timely replacement of parts with significant wear and tear should be carried out to ensure the normal operation of the submersible pump.
