What are the mechanical seal assembly precautions?


What are the mechanical seal assembly precautions?

  1, the assembly process should be dry, dust-free, clean pump mechanical seal working environment, keep the sealed cavity and the seal clean.

  2. In order to reduce the frictional resistance, during the installation, coat the contact surface of the auxiliary seal with a layer of clean mechanical seal oil or grease for the kettle. However, it must be noted that when using ethylene propylene rubber as an auxiliary seal, do not connect with mineral oil or grease. Clean or lubricate with water or soapy water.

  3, for the mechanical transmission of the spring drive, must pay attention to the rotation of the spring. It is generally seen from the back of the delicate ring to the direction of the rotating ring. The clockwise rotation axis needs to use the right-handed spring, and vice versa.

  4. The working height of the spring must reach the mounting height of the product sample or assembly drawing.

  5. Do not bump and knock on the seal during installation. After the sealing assembly is completed, the shaft, bushings, and the sealed end caps, etc., cannot be knocked or struck, so as to prevent the sealing failure due to the damage of the mechanical seal friction pair.
