Detailed Description
The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
Referring to fig. 1-3, the utility model discloses a pump for horizontal outlet and inlet of a concealed pipe water inlet pipeline, which comprises a pump body 6, wherein a pump water inlet volute 2 and a pump water outlet volute 8 are arranged in the pump body 6, a water diversion baffle 3 is arranged in the pump water inlet volute 2, a water inlet pipeline 1 is arranged on one side of the pump water inlet volute 2, a water outlet pipeline 5 is arranged on one side of the pump water outlet volute 8, an impeller 7 is further arranged at the center of the pump body 6, and impeller inlets 9 are arranged on two sides of the impeller 7. The pump-in volute section 10 and pump-out volute section 11 are shown in fig. 2.
The pump outlet volute 8 adopts a volute type, and the cross-sectional area of the pump outlet volute gradually increases from the pump outlet volute nose 4 to the pump outlet. Because the section of the pump water outlet volute chamber 8 is from small to large, and the pump water inlet volute chamber 2 and the pump water outlet volute chamber 8 have space overlapping parts, the outer wall surface of the pump water outlet volute chamber 8 is the inner wall surface of the pump water inlet volute chamber 2, and the cavity (only limited on the pump body 6) in front of two bedrooms is increased in consideration of the overall structure and the circulation smoothness of the pump water inlet volute chamber 2. Although the flow channels on the two sides of the water inlet volute 2 of the pump cannot be completely symmetrical, the influence of asymmetry is negligible from the perspective of a speed flow field.
The lowest inlet of the pump water inlet volute 2 sucks the forehearth medium, after the forehearth medium reaches the water inlet partition plate 3, the medium flows through the impeller 7 in two symmetrical paths, and after the impeller 7 applies work to the medium, the medium flows out of the pump water outlet volute 8.
The impeller 7 is connected with a driver 11 through a shaft, the driver 11 can be a motor, and the driver 11 drives the impeller 7 to rotate through the shaft.
The water inlet pipeline 1 is positioned underground, the underground depth is pre-buried according to the depth of the front pool, the distance between the pipeline inlet and the surrounding barriers and the frost resistance factor, the outlet pipeline 5 and the unit are positioned on the ground, and the installation, the overhaul and the control operation (the valve adjustment) are convenient.
The inlet and outlet of the pump are all on the pump body, namely below the middle open surface, when the pump head is overhauled, the pipeline and the driving stage are not required to be disassembled, the driving stage is disconnected, the pump cover is uncovered, and the rotor is called out for overhauling.
The working principle of the utility model is as follows: the main structural characteristics of the horizontal double-suction pump centrifugal pump are maintained, the overall requirement of the system is integrated, the inlet direction of the pump is changed, the inlet of the pump is vertically arranged at the downward position, the inlet pipeline 1 in the system is adjusted to be a hidden pipe, the outlet pipeline 5 is an open pipe, the height of a front pool is reduced, and meanwhile, the convenience of installation/maintenance/control operation (valve adjustment) of a unit is ensured.
The design of the pump water inlet volute chamber 2 is as follows: the front pool medium is sucked from the inlet at the lowest end, flows into and out of the impeller 7 in two symmetrical paths after reaching the water inlet partition plate 3, and flows out of the pump water outlet volute 8 after the impeller 7 applies work to the medium.
The foregoing describes one embodiment of the present utility model in detail, but the description is only a preferred embodiment of the present utility model and should not be construed as limiting the scope of the utility model.
