本文介绍了两种制取泡沫冲洗液的方式:有空压机式和无空压机式。一、有空压机式有空压机式系采用空压机,将其排出的压缩空气通过专门装置送入泥浆泵泵出的高压液流中,从而制取泡沫冲洗液。此装置一方面可使压缩空气在冲洗液中起发泡作用,另一方面又可在钻杆柱内液流压力急剧增加时,防止泡沫冲洗液倒流至空压机风包。其安装位置在流量计后面。空压机压力应大于冲洗液循环系统 This article describes two ways to make foam rinse solution: air compressor and air compressor. First, there is an air compressor air compressor system with air compressor, the compressed air discharged through the special device into the high pressure pump out of the high pressure liquid flow, so as to obtain foam rinse solution. On the one hand, the device can make the compressed air play a role of foaming in the flushing liquid and on the other hand, can prevent the backflow of the foam flushing liquid to the air bag of the air compressor when the pressure of the liquid in the drill string increases sharply. The installation location behind the meter. Air compressor pressure should be greater than the rinse liquid circulation system
