QJ deep well submersible pump is a new kind of machinery of drawing water. It consists of the electrical machinery and the diving pump. It is widely use in hydraulic engineering facility for example irrigation on farmland, draining waer in industry and mining enterprise, architectural engineering precipitation, also in cooling system of river, reservoir, eruptive fountain, hot spring bathing place and so on. It's main characteristic is that the combination of pump and electrical machinery, working in the deep water, easy to use, repairs, with great efficiency, also safe and reliable. Operation condition 1. Power source: AC, three phase380V /220V, 50Hz 2. Water qualities: A. Not above 25 c ( 85 c for the type of heat-resisting ) B. Shot contents ( mass ratin) not above 0.01% C. pH 6.5 ~ 8.5 D. Content of hydrogen sulfide not above 1.5 mg/l E. Chloride ionnot above 400 mg/l 3. The diving electrical machinery must be fully filled with clean water is used in water completely. 4. The install depth can not exceed the fixed lift 20%, and require the wall of the well smooth and straight.
