Embodiment Construction

[0011] Such as Figure 5 Shown, described a kind of double-suction volute chamber split centrifugal pump presses out chamber hydraulic diagram according to the following steps:

[0012] (1) According to the design parameters of the water pump, calculate the cross-sectional dimensions of (1~8) of the flow channel.

[0013] (2) Calculate and determine the position of the tongue (1) according to the ratio of rotation.

[0014] (3) Another tongue (2) is set at a position 180° away from the tongue (1) and at a position where the circumference radius is equal.

[0015] (4) Make (1-4) cross-sectional views from the tongue (1) respectively.

[0016] (5) start to make (5~8) cross-sectional diagrams from the tongue (2), these sections are both inner and outer double runners, and all design parameters of the inner runners will be exactly the same as those corresponding to the 180° angle. The net cross-sectional area of ​​the outer flow channel is equal to the calculated (5-8) cross-se...

Abstract

The invention relates to the technical field of water pumps, in particular to a centrifugal pump formed in a double-suction volute chamber. According to the centrifugal pump formed in the double-suction volute chamber, two flow channels are arranged in a pressured volute chamber; a separation tongue is respectively arranged at the symmetrical positions of the volute chamber, where central angles of the two flow channel are mutually 180 degrees; all parameters and the shapes of the two flow channels are completely consistent, so that the impeller can generate radial forces with the same size and opposite directions at the symmetrical position of 180 degrees in the center of the impeller during work; and due to the opposite directions, the two radial forces mutually offset and further the action of eliminating the radial forces is achieved.
