In the hydraulic system, hydraulic cylinder tightness can prevent leak of cylinder and dust entering. Seals play the role of elements, namely seals.
Leakage will pollute the machine，the environment and even give rise to malfunctioning machinery and equipment for personal accident. Leakage within the hydraulic system will cause a sharp drop in volumetric efficiency amounting to less than the required pressure can’t even work.
Invasive system dust particles can cause or exacerbate the hydraulic friction and wear components, and further lead to leakage.
Thus,hydraulic cylinder seals device and hydraulic cylinder tightness play an important role in hydraulic equipment. The reliability of its work and the working life how long it has is an important index to measure the good or bad of hydraulic system.
