液压传动,由于具有很多优点而被广泛应用。但液压件加工精度要求高,且品种规格型号较多,使得为维护液压设备正常运转所需的备件贮备量很难掌握。据我们多年的维修经验,通过同类型液压元件的改型,相互替代,是减少液压件贮备有效途径。所谓液压件的“改型代用”,实质上要求液压元件设计上的系列化、标准化和零、部件通用化的性质。“改型代用”时应注意以下几点:
Hydraulic drives are widely used due to their many advantages. However, high precision machining requirements of hydraulic parts, and more varieties and specifications, making it necessary to maintain the normal operation of hydraulic equipment spare parts storage is difficult to master. According to our many years of maintenance experience, through the same type of hydraulic components of the modified alternative to each other, is to reduce the effective way to store hydraulic parts. The so-called hydraulic parts of the “alternative”, essentially requires the design of the series of hydraulic components, standardization and zero, the general nature of the components. “Modified substitute” should pay attention to the following points:
