砂石泵是反循环工程钻机的重要配套件,其性能的好坏对于钻机的速度及其成孔率有着极其重要的作用和影响。交通部科技局十分重视砂石泵的研制工作,1984年下达了8PSS—A型砂石泵的研制任务。由交通部公路规划设计院设计,山东潍坊市农机修造厂制造的8PSS—A型砂石泵,通过二年的努力,完成了样机试制、清水性能试验及工业性使用试验,获得成功,1987年10月9日,由交通部科技局主持,在山东省潍坊市对该样机通过了技术鉴定。鉴定认为:8PSS—A
Sand pump is an important supporting component of reverse circulation engineering drilling rig, and its performance is very important for the drilling machine speed and its porosity has a very important role and influence. Ministry of Transportation Technology Bureau attaches great importance to the development of sand pump, issued in 1984, 8PSS-A-type sand pump development tasks. The model 8PSS-A sand pump, which was designed by the Highway Planning and Design Institute of the Ministry of Communications and was built by Weifang Agricultural Machinery Repair Factory, completed the prototype trial, clean water performance test and industrial use test through two years of hard work. In 1987, 10 On the 9th, chaired by the Science and Technology Bureau of the Ministry of Communications, the prototype was passed the technical appraisal in Weifang, Shandong. Identification that: 8PSS-A
