The function and significance of seals for hydraulic pipe joints
In hydraulic systems and their systems, sealing devices are used to prevent the leakage of working media and the intrusion of external dust and foreign matter. The sealing element, that is, the seal.
Leakage will cause the waste of working medium, pollution of the machine and the environment, and even cause the failure of mechanical operation and equipment accidents.
Internal leakage will cause a sharp decline in hydraulic system volume efficiency, can not reach the required working pressure, or even can not work.
Small dust particles invading the system can cause or aggravate the wear of the friction pair of hydraulic components, further leading to leakage.
Therefore, seals and sealing devices are an important part of hydraulic equipment. Its working reliability and service life is an important index to measure the quality of hydraulic system.
In addition to the gap seal, are the use of seals, so that the gap between the adjacent two coupling surface control in the need to seal the liquid can pass through the small gap below.
