Technical requirements for seals and gaskets for submersible sewage pumps

Submersible sewage pump is an important equipment in water treatment system, its performance and stability are directly related to the effect and efficiency of sewage treatment. In the structure of submersible sewage pump, the sealing ring and gasket ring are the key sealing parts, which play a vital role in preventing the leakage of the medium and ensuring the safe operation of the pump. Therefore, the technical requirements for the seal ring and the gasket ring of the submersible sewage pump are very strict.

First of all, the sealing ring is the main sealing element of the submersible sewage pump, and its material selection is very important. The sealing ring material should have excellent corrosion resistance, wear resistance, high temperature resistance and good elastic recovery ability. Common sealing ring materials include nitrile rubber, fluorine rubber, silicone rubber, etc., which can maintain stable sealing performance in different media and working environments. 

In the design of the sealing ring, it is necessary to consider its cross-section shape, size and matching accuracy with the sealing surface. The cross section shape of the sealing ring should be able to ensure that it can be evenly deformed under pressure to form a tight sealing line. At the same time, the size of the sealing ring should match the sealing groove to avoid tight sealing or installation difficulties caused by too large or too small. In addition, the matching accuracy of the sealing ring is also a key factor affecting its sealing effect, and the manufacturing tolerance must be strictly controlled to ensure the fit degree with the sealing surface. 

As an auxiliary sealing part of submersible sewage pump, the technical requirements of the gasket ring can not be ignored. The main function of the gasket ring is to support the sealing ring and ensure that it can maintain a stable sealing state during the working process. The material of the gasket ring should have sufficient strength and hardness to withstand the pressure and vibration inside the pump body. At the same time, the surface of the gasket ring should be smooth and flat, without obvious bumps and defects, to ensure a close fit with the sealing ring.

In terms of installation, the installation position, direction and compression of the sealing ring and gasket ring need to be carried out in strict accordance with the technical requirements. Before installation, clean and check the sealing surface and sealing components to ensure that there are no impurities or damage. During installation, control the amount of compression to avoid sealing failure or damage to sealing components caused by too large or too small. 

In addition, the regular inspection and replacement of the seal ring and gasket ring of the submersible sewage pump is also an important measure to ensure the stability of its performance. During use, the sealing ring and gasket ring may be affected by wear, aging and other factors, resulting in a decline in their sealing performance. Therefore, it is necessary to check the submersible sewage pump regularly, and once the sealing ring or gasket ring is found to be damaged or the performance is reduced, it should be replaced in time. 

In summary, the technical requirements of the seal ring and gasket ring of the submersible sewage pump involve many aspects such as material selection, design and manufacture, installation and use, and maintenance management. Only by strictly operating in accordance with technical requirements can we ensure the stable and reliable sealing performance of the submersible sewage pump and provide a strong guarantee for the safe and efficient operation of the water treatment system.
