The hydraulic cylinder oil seal is a sealing device used to control the flow of oil inside the hydraulic cylinder. It mainly plays the role of preventing oil leakage and preventing dust from entering the hydraulic cylinder. The hydraulic cylinder oil seal is composed of piston (piston oil seal), piston rod (piston rod oil seal), piston guide sleeve (guide ring) and end cap, etc. The working principle is to prevent the leakage of oil in the hydraulic system through the interaction between the contact pairs of the seal.
Hydraulic cylinder oil seal plays an important role in mechanical equipment, can effectively prevent liquid oil or liquid from leaking from the inside of the equipment to the outside of the equipment, reduce the loss of the equipment, and can avoid safety accidents caused by oil leakage. In addition, the oil seal can also prevent external dust and impurities from entering the inside of the equipment to protect the normal operation of the equipment. At the same time, the oil seal can also reduce the vibration and noise of the equipment, improve the working efficiency and operation stability of the equipment.
In short, the hydraulic cylinder oil seal is an important part of the hydraulic system, which is of great significance for ensuring the normal operation of the hydraulic system and extending the life of the equipment.
The hydraulic cylinder is also called the oil cylinder, which is driven by hydraulic pressure to achieve linear movement of the hydraulic pressure, composed of cylinder, cylinder head, piston, piston rod and sealing device. In order to move the piston in the cylinder, it is necessary to provide a path for the oil to flow into and out of the cylinder. In order to ensure the constant flow of the hydraulic cylinder, it is necessary to install the sealing ring, the hydraulic cylinder has simple structure and reliable work. When it is used to achieve reciprocating motion, it can not only remove the deceleration device, but also have no transmission gap, and the movement is very smooth, so it is widely used in various mechanical hydraulic systems.
