对液压矩-阶式组合密封系统及其在汽车起重机上的应用进行了研究。矩——阶式组合密封系统的应用能大大提高液压缸综合密封性能;该密封系统不仅适用于往复运动液压缸,而且还适用于静压支承液压缸。
Hydraulic moment - step combination seal system and its application in truck crane are studied. The application of moment-step combination sealing system can greatly improve the integrated sealing performance of the hydraulic cylinder. The sealing system is not only suitable for reciprocating hydraulic cylinders, but also for hydrostatic supporting hydraulic cylinders.
