我国第一台液压防爆绞车是从日本三井三池机械制作所引进的,已在山东兴隆庄矿、淮南潘集矿使用。这种绞车主要缺点是噪音大,但从我们调查的情况来看,使用效果还是令人满意的。一、概述这种绞车采用液压传动,适用于井下提升,适用的斜井倾角平均为1O°,一般为7°～12°。由一台防爆型鼠笼电动机拖动一台通轴式轴向柱塞双向变量泵,输出压力油,供给轴
The first hydraulic explosion-proof winch in our country was introduced from Mitsui Sanchi Machinery Manufacturing Co., Ltd. in Japan. It has been used in Xinglongzhuang Mine in Shandong and Panji Mine in Huainan. The main disadvantage of this winch is noise, but from our investigation of the situation, the use of results is satisfactory. I. Overview This kind of winch adopts hydraulic transmission and is suitable for downhole lifting. The suitable inclined angle of inclined shaft is 1O ° on average, generally 7 ° ~ 12 °. An explosion-proof squirrel-cage motor drag a through-axis axial piston bi-directional variable displacement pump, the output pressure of oil supply shaft
