Precautions for the application of hydraulic seals

Hydraulic seals are very important in hydraulic systems, because hydraulic transmission uses hydraulic pressure to transmit power. The quality of the seal device will directly affect the working performance of the hydraulic system.

If the hydraulic cylinder is not well sealed, it will cause serious internal and external leakage, which will cause the force and working speed to fail to meet the design requirements, increase power loss, reduce efficiency, pollute the environment, waste oil, and even cause fires. Therefore, seals are very important in hydraulic systems.

Seals can be used to prevent oil leakage and external air, dust, etc. from intruding into the hydraulic system. Of course, it is impossible for a hydraulic cylinder to be absolutely sealed. Because of the reciprocating movement of the piston rod, the oil must always be brought out.

However, this leakage is required to be as small as possible. On the contrary, if the piston rod does not bring out the slightest oil when reciprocating, the piston rod will be in dry friction, which will affect the working life and performance of the hydraulic cylinder.

Hydraulic seals are the core of hydraulic equipment and guarantee the normal operation of hydraulic equipment. First of all, we must understand the working performance, working pressure, working oil temperature, working medium hydraulic oil and movement speed of the factory’s hydraulic equipment and other environmental conditions, and at the same time, we must also understand The sealing characteristics, structural form, and sealing material performance of hydraulic seals.

Ensure the design and manufacture quality of seals, sealing surfaces, seal grooves, and seal assembly quality, reduce hydraulic oil pollution and enhance protection awareness, strengthen the supervision and detection of hydraulic oil pollution, and replace hydraulic oil pollution in time. Good storage and custody of hydraulic seals. Based on this comprehensive analysis and comparison, the common hydraulic seals with suitable structure and suitable materials are selected.
