液压软管常用于系统的活动部件或振动部位的柔性连接中,虽已有系列化标准,并有专业厂生产制造,能满足一般使用上的要求,但随着科学技术的发展和尖端领域的开拓,对液压软管也提出更高的性能要求。如果选用不当,会在调试或实际运行中造成系统的故障(如管体鼓泡、内部阻塞、管体破裂、接头渗油和接头脱落等现象),甚至发生重大事故。为了保证系统正常运行,要求选用正确、接头设计合理,检验把关,安装使用合理。本文的讨论适用于温度、压力有苛严要求的使用场合,也可用于一般场合。液压软管类型大致可分为三种:1)金属软管;2)橡胶软管;3)聚四氟乙烯,以及其 Hydraulic hoses are commonly used in the flexible connection of moving parts or vibrating parts of the system. Although there are series of standards and are professionally manufactured and manufactured to meet the requirements of general use, with the development of science and technology and cutting-edge fields Development, the hydraulic hose also put forward higher performance requirements. If used improperly, it will cause system failure during commissioning or actual operation (such as bubbling, internal blockage, rupture of pipe body, leakage of joints and joints, etc.) and even serious accidents. In order to ensure the normal operation of the system, require the correct selection, joint design is reasonable, check the gate, the installation is reasonable. The discussion of this article applies to the use of temperature, pressure demanding applications can also be used for general occasions. Hydraulic hoses can be roughly classified into three types: 1) metal hoses, 2) rubber hoses, 3) polytetrafluoroethylene, and
