常村矿选煤厂空气压缩机的改造

针对常村矿选煤厂冷却过滤机的风冷式空气压缩机经常由于高温停机的问题，分析了可能的人为、环境及设备本身的问题后，确定了相应的改进措施，即加装空气净化系统，同时将压风机自带的风冷系统改为水冷系统。经过改造后，解决了压缩机的散热问题，提高了选煤厂的生产效率。

Air compressor retrofit in Changcun coal preparation plant

In order to resolve the problems of air-cooled air compressor shutdown because of high-temperature, which provides wind for filter in Changcunkuang coal preparation plant. Analyze possible reasons of man-made, environment and equipments themselves. Confirm the corresponding improving method, which is rettrofiting air cleaning system, meanwhile, water-cooling system replaces air-cooling system. After innovation, the problem of heat dissipation is resolved and production efficiency of coal preparation plant is enhanced.
