Improper installation of hydraulic seal failure is a major cause. Install the most attention is required: (1) cleanliness; (2) to prevent damage to the hydraulic seal is to prevent nicks; (3) proper lubrication. Other aspects of the problem is that the hydraulic seal gland follower key position can be adjusted too tight seal, or during the installation of the hydraulic sealing lip is folded. Installation inverted  Hydraulic adapters  seal is also a common condition. To solve these problems is to focus mainly common sense and be more careful during the installation process.Foreign body hydraulic system is another major factor in seal failure. It is usually caused by some external factors, such as dirt, gravel, dirt, dust, or ice, and a number of internal factors, such as metal fragments, emulsion, hose or other system component degradation caused by other decomposition products. In the descending column process, many foreign objects into the machine systems are likely to be in this, the best solution is properly installed wiper or scraper. And the best way to avoid internal contamination lies in a suitable liquid filtration systems. Sometimes a small piece of metal is embedded in the seal member, the need to pay attention to the problem caused by dirt and scratching of the cylinder inner surface of the cylinder, excessive wear, seal leakage and so on.
