Volute chamber structure of horizontal pump

Abstract

The invention discloses a volute chamber structure of a horizontal pump. A water allocation piece is arranged in a spiral flow channel formed between an impeller and a pump body; the water allocation piece is spirally shaped and arranged along the flow channel; and the starting end of the water allocation piece in the water flow direction in the flow channel is tangential with the base circle of the pump. With the technical proposal, according to the volute chamber structure of the horizontal pump, the water allocation device is additionally arranged in an appropriate position of the spiral flow channel of the large-flow horizontal pump body; in other words, the spiral flow channel is divided into two parts; in this way, noise generated due to great centrifugal force is reduced, the radial force is greatly balanced and the service life of a motor bearing is prolonged; therefore, the operation of the pump is reliable, the fault possibility of the pump is reduced and the efficiency of the pump is improved; and as a result, the service life of the pump is prolonged.

Description

technical field [0001] The invention relates to a horizontal pump, in particular to a scroll chamber structure of the horizontal pump. Background technique [0002] At present, the design of horizontal pumps generally adopts the spiral horizontal type, and the cross-section is usually pear-shaped or rectangular. Pumps with small flow rate to large-flow pumps usually have this structure, and the radial force generated by small pumps due to small power is relatively small. , the use of the above structure has little impact on the pump itself, and large flow pumps, such as pumps with hundreds or thousands of tonnages, have serious defects in the above structure. In addition to the large noise, the most important thing is that the generated radial force is greatly shortened. The life of the motor bearing is shortened, which affects the quality of the pump. Contents of the invention [0003] In order to solve the above problems, the object of the present invention is to provid...

[0002] At present, the design of horizontal pumps generally adopts the spiral horizontal type, and the cross-section is usually pear-shaped or rectangular, which is usually the structure of small flow pumps to large flow pumps , the radial force generated by the small pump due to the small power is relatively small, and the above-mentioned structure has little influence on the pump itself, while the large-flow pump, such as a pump with a capacity of hundreds or thousands of tons, has serious defects if the above-mentioned structure is adopted. In addition to the large noise, the most important thing is that the generated radial force greatly shortens the life of the motor bearing, thus affecting the quality of the pump
