Embodiment Construction

[0041] The specific implementation manner of the present invention will be further described below in conjunction with the accompanying drawings.

[0042] Such as figure 1 As shown, the circulating water pump includes a water pump volute 1, an impeller 2 and a transmission shaft 3 located in the water pump volute 1, the impeller 2 is sleeved on the transmission shaft 3 and fixedly connected, and a motor (not shown in the figure) for driving the transmission shaft 3 Show). When working, the motor drives the transmission shaft 3 to rotate, the transmission shaft 3 drives the impeller 2 to rotate, and the impeller 2 drives the water circulation of the water pump volute 1 at the same time.

[0043] In this example, if figure 2 As shown, the impeller 2 includes two cylindrical bodies 21 symmetrically distributed from both sides to the center, two bell mouths 22 symmetrically distributed and whose diameter gradually increases from both sides to the center, and an impeller body 23...

Abstract

The invention discloses a circulating water pump which comprises a water pump volute, an impeller, a transmission shaft and a motor used for driving the transmission shaft. The impeller and the transmission shaft are located in the water pump volute. The transmission shaft is sleeved with the impeller, and the impeller is fixedly connected with the transmission shaft. The impeller sequentially comprises two symmetrically-distributed cylinders, two symmetrically-distributed horn mouths, and an impeller body from the two sides to the center, wherein the diameters of the two horn mouths are gradually increased from the two sides to the center. The cylindrical faces and the water pump volute are sealed through sealing rings. A gap is reserved between each horn mouth and the water pump volute. A plurality of blades are formed on the impeller body. The invention further discloses a method for transforming the circulating water pump. The water pump flow of the circulating water pump is large, the efficiency of a circulating water system is high, and a good energy-saving effect is achieved.

Description

technical field [0001] The invention relates to the field of circulating water systems, in particular to a circulating water pump used for jig coal washing and a method for transforming the circulating water pump. Background technique [0002] The coal washing circulating water system is a commonly used coal washing system. Through the conveying pipeline, it supplies water to the high-level coal washing jig machine. After the circulating water washes the coal, it flows back to the pipeline through the circulating water, and returns to the concentration tank by gravity for recycling. The motor power of a single circulating water pump in the coal washing circulating water system is 280kw, 6kv. The comprehensive energy efficiency of the system is generally not high, and the energy saving potential is great. [0003] In the energy-saving transformation of the coal washing circulating water system, the common method is to improve the efficiency of the circulating pump or the freq...
