机车风泵是列车制动机中的重要装置之一,它供给机车(或列车)压缩空气质量的好坏,直接影响列车安全、牵引重量和列车运行速度。同时对机车车辆制动部件的维修周期和使用寿命,以及油脂、消耗和运输成本都有直接关系。 我国现行蒸汽机车单、复式风泵的空气筒涨圈均为普通灰口铸铁(HT20—40)采用压缩机油润滑,在供给机车及列车压缩空气的过程中,将大量的机油带入制动系统中的总风缸和列车管内。它在减少总风缸贮风容积的同时,还腐蚀制动软管等部件。当夏季环境温度在35℃以上或瞬间缺油的工况下,
Locomotive air pump is one of the important devices in train brake system. It supplies the quality of locomotive (or train) compressed air quality, directly affects train safety, traction weight and train speed. At the same time, the maintenance cycle and service life of the rolling stock brake components are directly related to the grease, consumption and transportation costs. China’s current steam locomotive single and double pump air cylinder up ring are ordinary gray cast iron (HT20-40) using compressor oil lubrication, in the supply of locomotives and train compressed air process, a large number of oil into the brake The system of the total cylinder and train tube. It reduces the total air cylinder storage volume, but also corrosion brake hose and other components. When the summer ambient temperature is above 35 ℃ or short of oil under the conditions,
