几年前,我厂利用自行车打气筒的原理,设计制造了一种简易的液压油缸,曾先后应用于双侧6吨自卸拖车(详见本期19页)、1吨自卸汽车、小液压剪床(详见《农业机械资料》1974年第4期)、25吨和50吨液压铲刺机、开榫机等机具上。该油缸曾在《农业机械资料》1974年第4期上介绍过,此后,各地多有来信来访,根据所提出的问题和交流的经验,以及近两年来的新认识作如下补充: 1.缸壁光洁度问题简易油缸具有制造简单,取材方便的特点,缸筒可利用各种尺寸的钢管制造。一般地说,缸内壁只须清除锈蚀便可使用,但为了尽可能地延长皮碗的使用
A few years ago, our factory used the principle of bicycle pump to design and manufacture a simple hydraulic cylinder. It has been applied to double-sided 6-ton dump trailer (see page 19 in this issue), 1 ton dump truck, small Hydraulic Shear (see “Agricultural Machinery Information” 1974 the fourth period), 25 tons and 50 tons of hydraulic shovel machines, mortising machines and other equipment. The cylinder was introduced in the fourth issue of Agricultural Machinery Information in 1974, and since then there have been many letters and visits from various places. Based on the issues raised and the experience of exchange, as well as the new understanding in the past two years, the following supplements are made: 1. Cylinder Wall smoothness problem simple cylinder with simple manufacturing, drawing characteristics of convenience, the cylinder can use a variety of sizes of steel pipe manufacturing. In general, the cylinder wall only need to remove the rust can be used, but in order to extend the use of cups as much as possible
