一九七二年初,我段试制一台列检更换重车轴瓦用的风动油镐,经一年多实际运用,证明具有体积小、重量轻、效率高、使用方便等优点,架起一个重车轴箱只需40～50秒时间,比过去提高效率两倍多,大大减轻了劳动强度。 一、构造原理 风动油镐分为风动油泵和压力机两部份。 1.风动油泵部分(图1) 风动油泵中采用了射流元体——双向气动放大器,代替不通常采用的错气阀,简化了结构,减轻了重量。风动油泵安放在油箱
In early 1972, I tried to manufacture a pneumatic oil picker for inspection and replacement of heavy-duty axle bearings. After more than a year of practical application, it proved that it has the advantages of small size, light weight, high efficiency and easy to use. Heavy axle box only 40 to 50 seconds, more than double the efficiency in the past, greatly reducing the labor intensity. First, the structural principle of pneumatic oil picker is divided into two parts of pneumatic pump and press. 1. Pneumatic Oil Pump Section (Figure 1) The pneumatic oil pump uses a jet body - a bi-directional pneumatic amplifier instead of the less commonly used wrong valve, simplifying the structure and reducing the weight. Pneumatic oil pump placed in the fuel tank
