View the content of the mechanical seal points to pay attention to

It is necessary to check the mechanical seal before assembling, especially to completely clean the key parts such as the moving ring, the static ring and the shaft sleeve. The following are some points to pay attention to when checking and cleaning the mechanical seal.​​

1. Check the dynamic ring of the mechanical seal

The dynamic ring and static ring of the mechanical seal are the top priority of inspection. When investigating, pay attention to whether there are scratches and cracks on the surface of the dynamic ring. If there are defects on the dynamic ring of the mechanical seal, there will be leakage problems after use. .​​

When checking the dynamic ring of the mechanical seal, use a professional tool to check whether the sealing surface is flat. If necessary, you can also perform a hydraulic test on the mechanical seal. If the dynamic ring sealing surface of the mechanical seal enters the pressure water, the dynamic ring will be separated and sealed. invalid.​​

When checking the dynamic ring seat of the mechanical seal, it is also necessary to pay attention to whether there are defects, such as whether there is damage to the dynamic ring seat, sealing rubber ring, etc., if there are defects, it will also lead to the failure of the mechanical seal.​​

2. View other parts of the mechanical seal

When inspecting the shaft sleeve of the mechanical seal, pay attention to whether there are defects such as burrs and grooves; when inspecting the compensation spring of the mechanical seal, pay attention to whether there is deformation and damage, and pay special attention to whether the tenacity coefficient of the mechanical seal has changed. If the mechanical seal is provided with a pumping mechanism, it is also necessary to check whether the helix of the mechanical seal is intact.​​

When checking the sealing rubber ring of the mechanical seal, the mechanical seal should pay attention to whether there are defects and impurities. If there are cracks or pores in the sealing rubber ring, it will affect the sealing function in normal work. In addition, when checking the rubber ring of the mechanical seal, it is also necessary to pay attention to whether the diameter of the mechanical seal is within the public service scale.
