How to properly install and maintain shaft seals?

The shaft seal is a precision component, and the assembly and storage of the shaft seal will affect the performance of the Grundfos mechanical seal. In terms of assembly, the cartridge mechanical seal cannot use brute force to squeeze the sealing element, and the shaft seal should be kept from dust and deformation of the imported mechanical seal. Shaft components installed on the shaft should prevent rust in the seat groove. The following introduces the precautions for installing shaft seals: 1. How to correctly select and install shaft seals? 1. Clean all necessary sealing tool components and seals without dirt; 2. Fit them into the piston groove securely; 3. Then put the mandrel on the piston rod; 4. Put the DSH sealing ring over the On the installation mandrel; 5. Gently push the seal into the piston groove with the aid of the mandrel, and the action should be steady; 6. Then remove the mandrel from the piston; 7. Push the sealing tool in while assisting the installation , so that the sealing tool completely covers the outside of the sealing ring. After completing the above steps, remove the sealing tool after waiting for 60 seconds. 2. How to properly maintain and store Dongsheng shaft seals? 1. Avoid high temperature during transportation, which will cause the deterioration of the sealing material; 2. Avoid strong sunlight, ozone, and radiation caused by the deterioration of the sealing material; 3. The lack of proper preservation methods will cause the sealing parts to deform; 4.
