Description

Technical Field

[0001] This utility model belongs to the field of water pump technology and relates to an axial pump body. Background Technology

[0002] Axial pumps are primarily used to transport liquids with relatively large flow rates and low pressures, such as water or air. An axial pump moves liquid from the pump's suction end to its discharge end via an impeller and is commonly used in industrial and civil applications, such as water supply systems, air conditioning systems, and ventilation systems.

[0003] Chinese patent publication number CN215058403U discloses an axial balancing pump, including a balancing pump body. The end face of the balancing pump body is connected to an outlet, and the periphery of the balancing pump body is connected to an inlet. The inner cavity of the balancing pump body is rotatably connected to a turntable. Several T-shaped blocks are slidably connected to the periphery of the turntable. One end of the T-shaped blocks is in contact with the inner wall of the balancing pump body. Several grooves that are adapted to the T-shaped blocks are opened around the periphery of the turntable. Limiting blocks are fixedly connected to both sides of the inner wall of the grooves. A spring is fixedly connected to the inner wall of the groove, and one end of the spring is fixedly connected to the bottom end of the limiting block.

[0004] The patent provides an axial balancing pump in which a turntable is installed in the pump body for flow guidance, but this structure has a high cost. Utility Model Content

[0005] The purpose of this invention is to address the aforementioned problems in the prior art by providing an axial pump body.

[0006] The objective of this utility model can be achieved through the following technical solution: An axial pump body includes a pump body, a support pipe, a rectifier housing, a rotor ring, and a water inlet. The water inlet is connected to the rotor ring, and the rotor ring is fixedly connected to the rectifier housing. The support pipe is fixedly installed between the pump body and the rectifier housing. The pump body has an L-shaped structure, with a connection port at the lower end and a water outlet at the upper end. An arc-shaped guide plate is formed inside the pump body, also having an L-shaped structure and fixed to both sides of the inner wall of the pump body. One end of the arc-shaped guide plate is fixed to both sides of the water outlet. A straight coupling is formed at the lower end of the pump body, communicating with the inside of the pump body. A pump shaft is fixed inside the pump body, passing through the lower inner end of the pump body and the straight coupling. A bearing seat is fixedly connected to the outside of the straight coupling. A shaft-connecting bearing is fixed at one end of the pump shaft, and the shaft-connecting bearing is fixed inside the bearing seat.

[0007] In the aforementioned axial pump body, a fixed groove is provided at the lower end of the arc-shaped guide plate, and the pump shaft is connected to the fixed groove.

[0008] In one type of axial pump body described above, one end of the pump shaft extends out of the bearing seat and a water pump clutch is fixedly connected to one end of the pump shaft.

[0009] In one type of axial pump body described above, a heat dissipation window is provided on the outer periphery of the direct coupling body.

[0010] In the aforementioned axial pump body, a rectifier is fixedly connected to one end of the pump shaft. The rectifier is located inside the rectifier housing, and a water pump hub is fixedly connected to the outside of the rectifier.

[0011] Compared with the prior art, the axial pump body provided by this utility model has the following beneficial effects: through the structural arrangement of the arc-shaped guide plate, water entering the pump body from the inlet can flow out from the outlet along the arc-shaped guide plate. The arc-shaped guide plate guides the water flow, increases the water flow rate, and the connection between the arc-shaped guide plate and the two sides of the inner wall of the pump body gives the arc-shaped guide plate a large area. Furthermore, the arc-shaped guide plate is close to the outlet, which greatly improves the head efficiency of this utility model, and the production cost is low. Attached Figure Description

[0016] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0017] like Figures 1 to 3As shown, this embodiment includes a pump body 1, a support pipe 2, a rectifier housing 3, a rotor ring 4, and a water inlet 5. The pump body 1 has an L-shaped structure, with a connection port 14 at the lower end and a water outlet 13 at the upper end. An arc-shaped guide plate 11 is welded and fixed inside the pump body 1. The arc-shaped guide plate 11 has an L-shaped structure in the same direction as the pump body 1 and is fixed to both sides of the inner wall of the pump body 1. The upper end of the arc-shaped guide plate 11 is close to the outside of the water outlet 13 and divides the water outlet 13 into two parts. The water flows into the pump body 1 from the connection port 14, flows along the arc-shaped guide plate 11 and flows out from the water outlet 13. The arc-shaped guide plate 11 increases the speed of the water flow, and because the upper end of the arc-shaped guide plate 11 is close to the outside of the water outlet 13, it increases the head.

[0018] like Figures 1 to 3 As shown, a direct coupling 12 is formed on the other side of the lower end of the pump body 1 and is connected to the inside of the pump body 1. The pump shaft 6 passes through the lower inner end of the pump body 1 and the direct coupling 12. Heat dissipation windows 121 are opened on both sides of the outer periphery of the direct coupling 12. A shaft bearing 61 is fixed to one end of the pump shaft 6. The bearing seat 7 is fixedly connected to the outside of the direct coupling 12. The shaft bearing 61 is fixed inside the bearing seat 7. One end of the pump shaft 6 extends out of the bearing seat 7 and a water pump clutch 8 is fixedly connected to one end of the pump shaft 6.

[0019] like Figures 1 to 3 As shown, the rotor ring 4 is installed between the inlet 5 and the rectifier housing 3. The rectifier housing 3 is fixedly connected to one end of the support pipe 2, and the other end of the support pipe 2 is connected to the connection port 14 of the pump body 1. The pump shaft 6 is installed inside the pump body 1 and passes through the pump body 1, the support pipe 2 and the interior of the rectifier housing 3 in sequence. One end of the pump shaft 6 is fixedly connected to the rectifier 9, which is located inside the rectifier housing 3. The pump hub 10 is fixedly connected to the outside of the rectifier 9.
