在毛主席革命路线指引下,我队广大职工遵照毛主席“独立自主、自力更生”的教导,大搞技术革新和技术改造,试制成功挠轴式螺杆泵.于去年七月分别在四个机台投入生产试验,与北京-800型钻机配套使用,在泥浆粘度为18～25秒、含砂量达3～6%的条件下运转,泵量、泵压均达到常用往复式水泵的指标.广大工人同志赞扬说:“螺杆泵,就是好,体积小,重量轻;泵压大,泵量均;事故少,易检修;结构简,造价低;多打钻,立功劳.”一、技术性能 Under the guidance of Chairman Mao’s revolutionary line, the vast majority of our team of workers follow the teachings of Chairman Mao “independent, self-reliance ”, vigorously promote technological innovation and technological innovation, pilot successful screw axis screw pump.In July last year, Taiwan put into production test, and Beijing -800 rig supporting the use of mud viscosity of 18 to 25 seconds, the sand content of 3 to 6% of the conditions of operation, pump, pump pressure have reached the common reciprocating pump indicators. The majority of workers praised the comrades: "screw pump, is good, small size, light weight; pump pressure, pump volume are; less accidents, easy maintenance; simple structure, low cost; Technical performance
