电动凿岩机是煤矿巷遭掘进实现动力单一化的主要电气设备,由电动机、主机、开关接线装置及支腿,水泵等几部分组成。由于其有投资省、搬迁方便、机器结构简单、维修方便、重量轻、噪音小、没有油雾等优点,更主要的是只用电源作动力,深受煤矿特别是中小煤矿的欢迎。目前全国已有26个省近千个矿在使用。电动凿岩机的工作条件十分恶劣,冲击振动严重,还受潮气和井下水侵袭,加之很多煤矿电源不稳定,在实际使用中发现原配套的2kW电动机定子绕组烧毁,使用寿命较短,电
The electric rock drill is the main electrical equipment which is excavated to realize coal mine roadway to realize single power. It consists of motor, main engine, switch wiring device, outrigger and water pump. Because of its investment in the province, easy relocation, the machine structure is simple, easy maintenance, light weight, low noise, no oil mist and other advantages, more importantly, only the power supply for power, by the coal mines, especially small coal welcome. At present, there are nearly 1,000 mines in 26 provinces throughout the country. Working conditions of electric rock drill is very poor, severe shock and vibration, but also by moisture and downhole water invasion, combined with many coal power instability found in the actual use of the original 2kW motor stator winding burn, short life, electricity
