由地质部勘探技术研究院和浙江鄞县地质仪表厂设计制造的BY-60型泥浆泵压力表,从1979年12月至1980年4月在我队常山兰花坞矿区“三八”钻机试用.该压力表配用在WX-200型卧式双缸双作用泥浆泵上.泵的最大排量为200公升/分,最大工作压力为60公斤/厘米~2.在孔壁稳定,没有坍塌掉块的情况下钻进,泥浆泵的工作压力为15～20公斤/厘米~2.冲洗液为清水按一定比例加入太古油或皂化液. 该压力表共在三个钻孔施工中试用,钻
The BY-60 mud pump pressure gauge, designed and manufactured by the Exploration Technology Research Institute of the Ministry of Geology and Zhejiang Yinxian Geological Instrument Factory, was tested in the “March 8” drilling rig of Changshan Lanhuamen Mine in our team from December 1979 to April 1980. The pressure gauge is used in the WX-200 horizontal double-cylinder double action mud pump.The maximum displacement of the pump is 200L / min, the maximum working pressure is 60kg / cm ~ 2.It is stable in the hole wall without collapse Drilling conditions, the working pressure of the mud pump is 15 ~ 20 kg / cm ~ 2. Flushing water to join a certain proportion of the Pacific oil or saponification liquid.The pressure gauge in a total of three drilling construction trial, drilling
