Hydraulic seals in the hydraulic system is crucial, because hydraulic fluid pressure are used for transmission of power, sealing directly affect the performance of the hydraulic system. Hydraulic cylinder is sealed properly, it will cause a serious leaks inside and outside, making action and speed of work does not meet the design requirements, resulting in reduced efficiency, increased power loss, wasting fuel, polluting the environment, and may even cause a fire. Therefore, the seals in the hydraulic system is very important. Seals are used to prevent leakage of oil gas, dust invades the hydraulic system and the outside world. Hydraulic cylinder sealing is absolutely out of the question, of course. Piston rod in reciprocating motion, would bring out the oil. However, such leakage requirements as small as possible. Conversely, if piston reciprocating movement, without the slightest of oil, put the rod in friction, can adversely affect job performance and service life of the hydraulic cylinder.

Installation of hydraulic seals:

1. check the piston, cylinder and related surface installation guide sleeve, full package clean, Burr-free, free-sided edges.

2. installation tools required are smooth, without edges and sharp corners, ensure that the installation process cannot any form of damage to seals

3 when installing in seals and cylinder tube surface a small amount of grease to facilitate installation, but rubber elastomer and sliding sealing rings grease is allowed between the residues, otherwise it will affect seal performance.

4. whether it is vertical or horizontal installation should maintain the coaxial degree of the piston and the cylinder tube, oversized eccentricity may damage the seals.

5. install speed should not be too fast can damage the seals.

6. storage and maintenance of hydraulic seals: hydraulic seals when storage and maintenance, hydraulic seals should be put inside a sealed moisture-proof plastic bag such as Teflon, well kept and the date such records, and then store in a dark place, avoid high temperatures or direct sunlight, such as improper storage and reduce its sealing properties.
