about Hydraulic cylinder As it is necessary to know the required site products in terms of their seals, we should try our best to get familiar with them, so as to obtain good sealing effect through accurate application in practice. Therefore, we will reach the above goals through some specific aspects.

1. Seal between cylinder barrel and cylinder head in hydraulic cylinder seal

In the hydraulic cylinder, for the sealing of cylinder barrel and cylinder head, O-ring is usually used to develop the sealing. Moreover, in the process of using the seal ring, attention should be paid to its fit clearance, which should be reasonable. In addition, if you want to improve the pressure bearing ability of the seal ring, you can install nylon backing on the extruded side. If you want to prevent looseness caused by vibration, you can increase the preload of flange bolts and cylinder head screws.

2. Sealing between piston rod and inner hole of cylinder head guide sleeve in hydraulic cylinder seal

With regard to this sealing mode, there can be Y-shaped, V-shaped, U-shaped and Yx shaped in decision, and everyone can make a choice according to the detailed reality. It is important to note that there are surface quality standards, and above all, there should be no impurities, bubbles, burrs, scratches and other defects. If there is any, it can only be changed.

3. Assembly requirements of piston seals

Among the hydraulic cylinder seals, there are some assembly requirements for the piston seals. Specifically, they are:

(1) Before disassembling the piston seal, it is necessary to check whether it is worn or damaged. If the damage is not good, disassembly cannot be developed, because it will affect the fit clearance.

(2) When dealing with the clamping key at the piston head, in terms of continuity, it should be flexible and there should be no axial clearance. If it is thread adjacency, then there should be a surplus pre tightening torque.

The teaching of the two specific sealing parts of the hydraulic cylinder, as well as the description of the disassembly requirements of the piston seals, hope that everyone can deepen their familiarity with the hydraulic cylinder seals through these three points, Oil cylinder manufacturer And we can apply knowledge to practice and make it play its due role and value. How can we benefit from it.
