Mechanical seal adjustment screw
Thread Content
I went to the workshop today, and it was found that two adjustment screws for the mechanical seal of one mixing tank were missing, as well as one set screw; however, there was no leakage from the tank. What is the function of this adjustment screw? It’s not for adjusting the compression volume, right? Isn’t the compression amount of a standard mechanical seal already adjusted upon leaving the factory? So what is the purpose of this adjustment screw? Two of the four adjustment screws are missing, and one set screw is missing. Mechanical seal drawings
Containerized mechanical shaft seals do not require adjustment screws; yours probably does
The image shows that it is possible to fine-tune the pressing force. 【Two of the four adjustment screws are missing, as well as one set screw, yet there is no leakage】; this is probably because it was installed properly at the time, and the pressure inside the equipment wasn’t high
Adjust the axial position of the moving ring assembly on the shaft in order to control the compression amount. «This structure is not modular and requires adjustment during installation». If the equipment vibrates too much and causes the screws to come loose, they should be reinstalled promptly
The screw fixed perpendicular to the shaft acts as a shaft holder, enabling the moving ring to rotate in sync with the shaft! The gland screw of the mechanical seal serves to compress the spring!
It is used to regulate pressure; models like 204 and 212 are of this kind. Containerized types are different, however
