Mining submersible pump common types have?
Today's mining submersible pump is mainly used for pump house drainage of coal mines, coal mine drainage drainage or mine drainage, commonly used centrifugal pump. Commonly used types of mining submersible pumps are D-type, DA-type and TSW-type multistage centrifugal pumps; B-type, BA-type and BZ-type single-stage centrifugal pumps are commonly used for bottom hole sump and partial drainage in mining areas. Next, a detailed analysis of D-type centrifugal pump and B-type centrifugal pump. Mining submersible pump common types have? 1, D-type centrifugal pump: D-type pump is a single suction, multi-stage, segmented centrifugal pump. The stator part of the pump mainly by the front middle, rear, tail cover and bearing frame and other components with bolts connected. The rotor part consists mainly of several impellers mounted on the shaft and a balance disc. The entire rotor is partially supported on bearings at both ends of the shaft. Between the front, middle and rear of the pump are bolted together, and the impeller and the guide ring at all levels are sealed by the big mouth ring and the small mouth ring before and after the impeller. In order to improve the water absorption, the suction port of the first-stage impeller is larger in diameter and its large-mouth ring is correspondingly enlarged. Pump shaft through the front and rear section of the seal by packing, packing gland stuffing box to complete. Pump axial thrust balance plate balance. D-type pump flow and lift range, the current maximum lift of this type of pump up to nearly l000m, flow rate of 450m3 / h, to meet the needs of mine drainage, and the efficiency curve is flat, larger industrial use. 2, B-type centrifugal pump: B-type pump is a single suction, single-stage, cantilever centrifugal pump. One end of the pump shaft is supported by a bearing in the carriage, the other end is cantilevered, and an impeller is mounted on the cantilever end. Bearings can be lubricated with grease or grease. B-type pump small size, light weight, simple structure, reliable, easy handling and maintenance. Its flow range is 4.5 - 360 m3 / h with a head of 8 - 98 m. Commonly used in the drainage of mining area, pit water pit water can be used as other auxiliary supplies, drainage equipment. Mine submersible pump main working parts are impeller, which has a certain number of blades, impeller fixed on the shaft, driven by the shaft rotation. The shell of the pump is a spiral diffusion chamber. The water suction port of the water pump is connected with the water suction port, and the water drain port is connected with the drainage pipe. Through the above analysis of mining submersible pumps we can understand that the main use of mining submersible pumps in the cause of the coal mine, not only for the drainage of coal mines, coal mine rescue, as well as the drainage of the mine. With the further improvement of coal mine safety requirements nowadays, the research and development of mine submersible pumps have great significance for the development of coal mine in our country.
