Hello, welcome to visit Dongguan Shengdao Silicone Rubber Products Co., Ltd. website!
The choice of seal material is of great significance to its sealing performance and service life. The performance of the material directly affects the performance of the sealing ring. What should you pay attention to when installing with a seal ring? The editor of liquid silicone products manufacturers tells everyone.
(1) Do not install the wrong direction and damage the lips. If there are more than 50μm scars on the lips, it may cause obvious oil leakage.
(2) Prevent forced installation. It cannot be knocked in with a hammer, but use a special tool to first press the seal ring into the seat hole, and then use a simple cylinder to protect the lip through the spline. Before installation, apply some lubricating oil to the lips to facilitate installation and prevent burns during initial operation. Care must be taken to clean it.
(3) Prevent overdue use. The service life of dynamic seal rubber seals is generally 3000 ~ 5000h, and new seals should be replaced in time.
(4) The size of the replacement seal should be consistent. The sealing ring of the same size should be selected in strict accordance with the requirements of the manual, otherwise the requirements such as tightness cannot be guaranteed.
(5) Avoid using old seals. When using a new sealing ring, you should also carefully check its surface quality, make sure that there are no defects such as small holes, protrusions, cracks and grooves and that it has sufficient elasticity before use.
(6) When installing, all parts of the opened hydraulic system should be strictly cleaned, and special tools should be used to prevent the sharp edges of the metal from scratching the fingers.
(7) When replacing the sealing ring, strictly check the groove of the sealing ring, remove dirt, and polish the bottom of the groove.
(8) To prevent oil leakage due to damage, operate according to the regulations, and at the same time, do not overload for a long time or put the machine in a relatively harsh environment for operation.
