Embodiment Construction

[0014] Such as figure 1 As shown, a double-suction pump high-efficiency suction chamber structure includes a suction chamber 1, a split section 2 and a spiral section 3, and the split section includes a left flow channel 6, a right flow channel 5, and a Between the volute wall 4, the volute wall 4 is provided with a water diversion tongue 7 extending toward the suction chamber 1.

[0015] In order to better realize the circumvention, participate in soil 3, Figure 4 The left side of the water diversion tongue and the right side of the left flow channel are connected together to form a smooth transitional arc surface; the right side of the water diversion tongue and the left side of the right flow channel are connected together to form a smooth transitional arc surface. Correspondingly, the water diversion tongue 7 has a streamlined structure.

Abstract

The invention relates to a high-efficiency suction chamber structure with double suction pumps, comprising a suction chamber, a diversion section and a spiral section, wherein the diversion section comprises a left flow channel, a right flow channel and a volute housing wall positioned between the left flow channel and the right flow channel; and the volute housing wall is provided with a water diversion tongue extending towards the direction of the suction chamber. The high-efficiency suction chamber structure solves the technical problem of low efficiency of the existing suction chamber with the double suction pumps, smoothly realizes streaming around, reduces flow resistance and improves the efficiency of the suction chamber.

Description

technical field [0001] The invention relates to a double-suction pump suction chamber structure. Background technique [0002] The volute wall in the suction chamber of the existing double-suction pump is a round head structure, such as figure 2 As shown, when the fluid is sucked into the pump, it is resisted by the flow around the volute wall, resulting in low efficiency of the suction chamber. Contents of the invention [0003] In order to solve the technical problem of low efficiency of the suction chamber of the existing double-suction pump, the invention provides a structure of a high-efficiency suction chamber of the double-suction pump. [0004] Technical solution of the present invention is: [0005] A high-efficiency suction chamber structure of a double-suction pump, including a suction chamber, a flow diversion section and a spiral section. The advantage is that: the wall of the volute is provided with a water diversion tongue extending toward the suction cha...
