slurry pump action in national economy you know?

The slurry pump is accompanied by the development of the industry. In nineteenth Century, foreign type and variety comparison complete slurry pump, and has been widely used. According to statistics, in 1880, general purposes centrifugal slurry pump output accounted for more than the entire slurry pump output by 90%, while the power device with slurry pump, chemical slurry pump and other special purpose slurry pump slurry pump, mine, accounted for only 10% of the whole slurry pump sewage slurry pump production. By 1960, general purpose slurry pump accounted for only about 45%, and special purpose slurry pumps accounted for 55%. According to the current development trend, special purpose slurry pumps, than the general purpose of the slurry pump to increase the proportion of.

In early twentieth Century, submersible slurry pump by the United States developed the first, use it to replace the deep well slurry pump. Subsequently, the Western European countries have also conducted research and development, and constantly improve, and gradually improve. Such as Germany’s Rhine brown coal, using various submersible slurry pumps more than 2500 units, capacity of the largest up to 1600KW, head 410m.

Submersible slurry pump in our country is developed in the nineteen sixties, the work surface submersible slurry pump in the South has long been used in agricultural irrigation, and small and medium capacity submersible slurry pump series has been formed, and put into batch production. The large capacity and high voltage electric submersible slurry pump, submersible motors also have been published, large submersible slurry pump 500-1200KW has been put into operation at the mine. For example, Anshan Steel Corp Yanqianshan Iron ore mine submersible slurry pump drainage 500KW, the rainy season effect. There are signs that, submersible slurry pump will be used to mine drainage equipment change, have instead of large horizontal slurry pump power. In addition, the submersible slurry pump larger capacity is in the trial production.
