液压传动系统中,由于密封件对压力、速度、功率、使用寿命、操作安全和环境保护等的要求最苛刻,因此对密封件的要求也比其它部件更高,如果没有这些要求,密封件就失去了其使用价值。 不同工况下零部件的相互作用情况也完全不同,因此对密封件的要求也不同。在密封件设计阶段应尽可能全面地考虑各种的要求,由此来决定密封件材料和形状的选择等。只有这样才能正确处理好液压系统密封问题,避免系统故障。
In hydraulic transmission systems, seals require the highest pressure, speed, power, service life, operational safety, environmental protection, etc. and therefore require more seals than other components. If not, the seals Lost its use value. Under different conditions of parts interaction is completely different, so the requirements of the seals are also different. In the seal design phase should be as comprehensive as possible to consider a variety of requirements, which will determine the choice of seal material and shape. Only in this way can properly handle the hydraulic system sealing problems, to avoid system failure.
