Precautions when installing and disassembling rubber seals seals There are several very important things when installing and disassembling rubber seals. If you are a little careless, the rubber seal will be damaged during installation. Application, if it is disassembled, it is easy to leave the aged seals on the machine, which will make cleaning very laborious, and if the cleaning is not clean, it will cause the seal to be loose after installing the new seals. When installing and removing the seal, pay great attention to several important matters. 1. Precautions during installation (1) Pay great attention to avoid installation deviations during installation a. Tightening the gland should be carried out after the coupling is aligned, and the bolts should be supported evenly to prevent the end face of the gland from being skewed. The feeler gauge checks each point, and the error is not more than 0.05 mm. b. Check the matching clearance (ie concentricity) between the gland and the outer diameter of the shaft or the shaft sleeve. (2) The amount of spring compression should be carried out in accordance with the regulations, and it is not allowed to be too large or too small, and the error is required to be 2.00 mm. If it is too large, the specific pressure of the end face will increase, and the end face will be worn at another speed. If it is too small, the specific pressure will be insufficient and the sealing effect cannot be achieved. (3) After the moving ring is installed, the beard is guaranteed to be able to move flexibly on the shaft, and it should be able to spring back automatically after pressing the moving ring against the spring. 2. Precautions when disassembling (1) Be careful when using the mechanical seal, and it is strictly forbidden to use a hand hammer and a flat shovel to avoid damage to the sealing element. A pair of wire hooks can be made, and the sealing device can be pulled out by extending into the gap of the transmission seat in the direction of self-financing. If the scale cannot be removed, it should be cleaned and then removed. (2) If mechanical seals are used at both ends of the pump, take care of each other during assembly and disassembly to prevent one from neglecting the other. (3) For the mechanical seal that has been run, if the gland is loose and the seal moves, the dynamic and static ring parts must be replaced, and should not be re-tightened for continued use. Because the original running track of the friction pair will change after the same movement, the sealing performance of the contact surface is easily damaged. The above are the precautions for the installation and disassembly of rubber seals seals, I hope to be helpful to everyone.
