Description

Technical Field

[0001] This utility model relates to the field of water pump technology, specifically a novel integrated water pump. Background Technology

[0002] A water pump, also known as a "piston pump," is a device that pumps water from various sources. Common types include piston pumps, centrifugal pumps, and axial-flow pumps. Piston pumps utilize atmospheric pressure, such as common water hand pumps. Centrifugal pumps use an impeller to generate centrifugal force, lifting the water to a higher position; however, the height of the water at the pump's suction inlet is still limited by atmospheric pressure. Axial-flow pumps work similarly to electric fans, with rotating impellers pushing water backward along the pump shaft. Axial-flow pumps have a large flow rate but a relatively small lifting height (head). Water pumps are widely used for agricultural irrigation and drainage, as well as water supply and drainage in industrial and mining enterprises and urban areas. Various types of water pumps are available to meet different needs.

[0003] Existing water pumps have many connecting parts, mainly belt connections, which are costly and bulky, making them inconvenient to hoist. Moreover, the connection between the engine and the impeller is usually through a coupling, but coupling connections are prone to failure, which is not conducive to the efficient use of the water pump. In addition, the blades inside the water pump are narrow, and they are often blocked by branches, roots, and stones during pumping, which affects the use of the water pump. Utility Model Content

[0004] The purpose of this invention is to provide a novel integrated water pump to solve the problems mentioned in the background section.

[0009] Preferably, the impeller center is provided with a second spline groove, and the second spline groove is adapted to be connected to the second spline.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: This new integrated water pump improves the connecting parts, and the engine is directly connected to the impeller by a splined shaft. The use of a detachable engine link reduces the number of connecting parts. This new integrated water pump uses fewer parts, is easier to install, and is easier to transport and hoist.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1 , Figure 2 and Figure 3This utility model provides a technical solution: a novel integrated water pump, comprising a pump body 18 and an engine 1. The engine 1 is a conventional structure for driving a water pump. A pump casing 15 is mounted on the pump body 18. A lifting seat 17 is symmetrically welded to the upper end of the pump casing 15, and each lifting seat 17 has a through hole. This symmetrical arrangement of the lifting seats 17 provides balance and facilitates the lifting of the pump body 18. A support frame 16 is symmetrically welded to the lower end of the pump casing 15. The support frame 16 has a U-shaped structure and is inclined. This structure supports… The frame 16 provides bottom support for the pump body 18 during installation, facilitating its placement. The inclined design of the frame 16 makes the pump body 18 more stable. Both sides of the pump casing 15 are connected to pump casing fixing asbestos discs 8, which provide a sealing function. One side of the pump casing 15 is provided with a pump casing end cover 10, and the other side of the pump casing 15 is connected to a connecting seat 13, which provides a connection. A bushing 11 is installed inside the connecting seat 13, and a packing sealing strip 7 is fitted on the outside of the bushing 11 for sealing.

[0017] One end of the bushing 11 is connected to an asbestos clamp 14. A splined shaft 2 is inserted inside the bushing 11. The two ends of the splined shaft 2 are respectively provided with a first spline 21 and a second spline 22. The engine output shaft 101 is provided with a first spline groove 102 that matches the first spline 21. In use, the first spline is connected to the first spline groove. The release bearing 3 is located inside the engine 1. In this structure, the release bearing 3 plays the role of clutch. Through the detachable connection, the number of connecting parts is reduced, saving about one-third of the cost compared with traditional water pumps. It is highly efficient and easy to hoist. A bearing 6 is sleeved on the splined shaft 2. The outer side of the bearing 6 is provided with a connection... The bearing housing 5 is connected to the seat 13, and an oil seal 12 is provided between the bearing housing 5 and the connecting seat 13. The oil seal 12 is used to seal the lubricating oil. The spline shaft 2 is fitted with a shaft cover 4 connected to the bearing housing 5, and a release bearing 3 is installed on the outer sleeve of the shaft cover 4. An impeller 9 is installed inside the water pump body 18, so that the water pump body 18 can not only pump water, but also pump mud-water mixture without clogging. The impeller 9 is connected to the spline shaft 2, and a second spline groove 91 adapted to the second spline 22 is provided on the impeller 9. The power output by the engine output shaft is directly transmitted to the impeller through the spline shaft 2 without going through the coupling, so that the impeller receives stronger power.

[0018] Working Principle: When using this new integrated water pump, the pump body 18 is first placed on a fixed surface with the support of the support frame 16. Then, the pump body 18 is hoisted and fixed using the hoisting seat 17, allowing the pump body 18 to be adjusted in position. During installation, the splined shaft 2 is inserted into the engine 1, and the release bearing 3 is used for clutch engagement and fixation. The shaft cover 4 provides protection for the splined shaft 2. The engine 1 can then drive the splined shaft 2 to rotate. The bearing 6 lubricates the splined shaft 2, and the bearing seat 5 secures and installs the bearing 6. Meanwhile, the bearing seat 5 supports the pump body 18, and the asbestos plate 8 for fixing the pump casing 15 on both sides. The connecting seat 13 is sealed to the pump casing 15 through the packing sealing strip 7, the bushing 11, and the asbestos clamp 14 to prevent leakage. The connecting seat 13 and the bearing seat 5 are sealed together by the oil seal 12. When the spline shaft 2 rotates, it drives the impeller 9 to rotate, so that the liquid is drawn into the pump casing 15 through the pump casing end cover 10. Then the liquid is discharged through the opening at the top of the pump casing 15. It can not only pump water, but also pump mud-water mixtures without clogging, thus improving the working efficiency of the pump body 18 and completing a series of tasks.

[0019] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
