概述金刚石钻进时,对冲洗液的测量很重要,因为冲洗液循环不正常,会引起烧钻等事故。由于冲洗液往往含有泥沙,使得多种流量计不能适用。叶轮或涡轮流量计和椭元齿轮流量计由于运动部件在含沙介质中使用寿命不长,不宜作为泥浆冲洗液的测量。压差式和毕托管式流量计由于测管易堵塞,也不能用来测量泥浆的流量。浮子式、靶式和电磁式流量计则没有上述缺点。但浮子式和
Overview diamond drilling, the measurement of the rinse solution is very important, because the rinse fluid circulation is not normal, can cause burns and other accidents. As the rinse fluid often contains sediment, making a variety of flow meter can not be applied. Impeller or turbine flowmeter and elliptical gear flowmeter Moving parts in sandy medium service life is not long, not as a mud washing liquid measurement. Pressure differential and BiTo tubular flowmeters are also susceptible to measuring mud flow due to easy plugging of the tubes. Float, target and electromagnetic flowmeters do not have these shortcomings. But float type and
