BW—1200型泥浆泵是地质矿产部张家口探矿机械厂根据国内当前开发地热资源和深部地下水的急需而研制的。经过厂内台架测试和野外生产性试验，证明该泵结构合理，性能良好，工作可靠，停修时间少，主要易损件寿命长，受到试验单位的好评。并在1983年12月由地质矿产部探矿工程装备工业公司组织的技术鉴定会上通过了鉴定。一、结构型式和技术参数从当前国内外用于地热资源钻探的大、中型泥浆泵来看，经常使用的有双缸双作用和三缸单作用两种
BW-1200 mud pump is the Ministry of Geology and Mineral Resources Zhangjiakou prospecting Machinery Factory in accordance with the current development of geothermal resources and deep groundwater in urgent need and developed. After the factory bench test and field production test, the pump proved to be reasonable in structure, good in performance, reliable in work, less in maintenance time and long wearing life of main wearing parts, and was praised by the test unit. And in December 1983 by the Ministry of Geology and Mineral Resources prospecting engineering equipment industry company organized technical appraisal meeting passed the appraisal. First, the structure type and technical parameters From the current domestic and international geothermal resources for drilling large and medium-sized mud pump point of view, there are often used two-cylinder double-acting and three-cylinder single-acting two
