First of all, when we assemble the press cylinder, we need to leak oil in order to avoid the leakiness formed on the machining. Therefore, when we install seals such as Glyd rings or O-rings, do not pull them to permanent deformation, and do not install them under rotating conditions. Secondly, we should note that the V-ring seal is composed of a different shape of the support ring, the seal ring and the pressure ring. When the pressure ring presses the seal ring, the support ring can make the seal ring shape and seal. The opening of the seal ring should face the pressure oil chamber.
The press machine manufacturer told us that when adjusting the pressure ring, it should be limited to no oil leakage, and should not be pressed too tightly to prevent the sealing resistance from being too large. For the Y-shaped seal ring, the lip should deal with the oil chamber with pressure; the Yx-shaped seal ring should also pay attention to distinguish whether it is for the shaft or the hole, and do not install the wrong. In addition, when installing the Y-shaped and V-shaped seals, pay attention to the installation direction to avoid oil leakage due to mistakes. There is also a sealing device such as a sliding surface. When assembling, a suitable amount of hydraulic oil should be applied to the surface to lubricate the surface and make assembly easier. As long as the removed sealing ring and the dust ring are damaged due to the disassembly process during the assembly process, the sealing function cannot be better, and all should be replaced. When installing the cylinder to the main unit, be careful to install a sealing ring between the inlet and outlet ports and tighten it to prevent oil leakage.
After the assembly is completed, it is necessary to test it first. After assembly as required, it can be repeated up and down several times under low pressure to eliminate the gas in the cylinder and let the hydraulic oil fill the cylinder so that the pressure is in the normal pressing of the press.
