Sealing technology is an indispensable technology of hydraulic cylinders, and the selection of appropriate seals can effectively reduce the failure rate of hydraulic cylinders in the working process, let's tell you how the seals of hydraulic cylinders work?
First of all, in order to ensure that the groove size tolerance of the cylinder itself can be perfectly compensated by seals, therefore, whether in the seal or the cylinder, in the production process, it must be strictly in accordance with the national standard groove size tolerance, roughness and other data requirements for mass production.
Secondly, if you do not pay attention to this problem during the production process. For example, if the groove is too deep, the gap between the root of the seal and the groove will cause the part to not fix, and the change in the amount of interference and rebound force between the lip and the sealing surface will lead to low-pressure oil leakage. If the groove is too shallow, it will also lead to faster damage to the seal lip and more frequent oil leakage.
Finally, the seal is generally working in the form of reciprocating motion, and the general shape has L, U, V, Y and other lip seals. Because of its design shape, it can ensure that the sealing surface fully contacts the lip in the reciprocating cylinder to ensure excellent sealing effect, and the size of the sealing contact force and area will become larger or smaller with the pressure in the reciprocating movement of the cylinder.
