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
The present invention relates to a kind of double suction pump suction chamber structure.
Background technique
Spiral case wall in the suction chamber of existing double suction pump is the round end structure, and as shown in Figure 2, it is big to be subjected to the resistance that the spiral case wall streams in the time of in the fluid suction pump, causes the efficient of suction chamber also low.
Summary of the invention
In order to solve the inefficient technical problem of suction chamber of existing double suction pump, the invention provides a kind of high-efficiency suction chamber structure with double suction pumps.
Technical solution of the present invention is:
A kind of high-efficiency suction chamber structure with double suction pumps, comprise suction chamber, shunting section and spiral section, described shunting section comprises left runner, right runner and the spiral case wall between left runner and right runner, and its special way is: described spiral case wall is provided with the branch overflow that extends to the suction chamber direction.
The left surface of above-mentioned minute overflow and the right flank of left runner link together and constitute the rounding off cambered surface; The right flank of described minute overflow and the left surface of right runner link together and constitute the rounding off cambered surface.
Above-mentioned minute overflow is streamlined structure.
The present invention is provided with the branch overflow on the spiral case wall, two inlets about suction chamber is divided into are equivalent to left and right sides runner is extended to suction chamber, have realized smoothly streaming, and have reduced flow resistance, have improved the efficient of suction chamber.
Description of drawings
Fig. 1 is the efficient suction chamber external structure of a double suction pump of the present invention schematic representation;
Fig. 2 is the suction chamber of existing suction chamber and the structural representation of shunting section;
Fig. 3 is the suction chamber of suction chamber of the present invention and the structural representation of shunting section;
Fig. 4 is that the B of Fig. 3 is to view;
Wherein: the 1-suction chamber, the 2-shunting section, the 3-spiral section, 4-spiral case wall, the right runner of 5-, 6-left side runner, 7-divides overflow.
Embodiment
As shown in Figure 1, a kind of high-efficiency suction chamber structure with double suction pumps, comprise suction chamber 1, shunting section 2 and spiral section 3, shunting section comprises left runner 6, right runner 5 and the spiral case wall 4 between left runner 6 and right runner 5, and spiral case wall 4 is provided with the branch overflow 7 that extends to suction chamber 1 direction.
To stream in order better realizing, to participate in right flank that soil 3, Fig. 4 divides the left surface of overflow and left runner and link together and constitute the rounding off cambered surface; The right flank of branch overflow and the left surface of right runner link together and constitute the rounding off cambered surface.Accordingly, dividing overflow 7 is streamlined structure.
