YT-25型凿岩机原来带有风水联动开关,由于这种开关是由凿岩机阻塞阀进风而动作,给风后,凿岩机带动钎子转动,但供水滞后,形成了先风后水的错误操作。因此,我矿在生产中有一时期未曾使用此开关。在群众性的防尘革新中,我们对YT-25型凿岩机风水联动开关的风路进行了一些改进,取得了较好效果。改革的内容是这样,将凿岩机柄体通气腿的推进气路孔钻通,钻一个直径为4毫米的小孔,把风路引出体外,再在原柄体装有注水阀位
YT-25-type rock drill originally with feng shui linkage switch, because this switch is blocked by the rocker valve into the wind and action, to the wind, the rock drill driven by the rotation of the braze, but the water supply lag, the formation of the first wind after the wrong operation. Therefore, mine has not used this switch for a period of time in production. In the mass of dust-proof innovation, we made some improvements to the wind path of YT-25 rock drill hydraumatic switch and achieved good results. The content of the reform is such that the drill hole of the stem of the rock drill body is drilled through the propulsion airway hole and a small hole with a diameter of 4 mm is drilled to draw the air path out of the body and then the water injection valve seat
