Detailed Description

The following are specific embodiments of the present application and are further described with reference to the drawings, but the present application is not limited to these embodiments. In the following description, specific details such as specific configurations and components are provided only to help the embodiments of the present application be fully understood. Accordingly, it will be apparent to those skilled in the art that various changes and modifications may be made to the embodiments described herein without departing from the scope and spirit of the present application. In addition, descriptions of well-known functions and constructions are omitted for clarity and conciseness.

In addition, the embodiments and features of the embodiments in the present application may be combined with each other without conflict.

Referring to fig. 1, an embodiment of the present application provides a hydraulic motor assembly for a pump, including: a housing 10 and an internal power structure 20 capable of driving the output shaft 21 to rotate; the housing 10 includes: the device comprises an outer cylinder body 11, an inner cylinder body 12 accommodated in the outer cylinder body 11 and guide vanes 13. A fluid channel 14 is formed between the inner cylinder 12 and the outer cylinder 11; the internal power structure 20 is housed and mounted in the inner barrel 12. The guide vane 13 is disposed between the inner cylinder 12 and the outer cylinder 11.

In the embodiment of the present application, the hydraulic motor assembly for the pump may employ a gear motor, a screw motor, a vane motor, a radial piston motor, or an axial piston motor. The internal power structure 20 is a component contained inside the housing 10 for converting fluid pressure energy into its output shaft. The internal power structure 20 of different hydraulic motor types is different, for example, the internal power structure 20 of an axial piston motor comprises: plunger subassembly, sloping cam plate, join in marriage oil pan, output shaft etc.. It should be understood that the internal power structure 20 of each type of hydraulic motor is within the scope of the prior art and will not be described in detail herein.

Adopt hydraulic motor drive water pump in this application embodiment, need not electric power, can use under the condition that does not have power supply, and no electric power leaks, and is safer.

In the embodiment of the present application, the housing 10 directly serves as a guide vane body, and includes: outer cylinder 11, inner cylinder 12, guide vane 13. A fluid passage 14 is formed between the inner cylinder 12 and the outer cylinder 11 for guiding the flow of liquid. When making the hydraulic motor assembly for pump, directly install internal power structure 20 on barrel 12 in, overall structure is compacter, more lightweight.

Referring to fig. 2, the water pump includes the above pump hydraulic motor assembly, an impeller 30 mounted on the output shaft 21 of the hydraulic motor, and a water inlet bell pipe 40 connected to the outer cylinder 11. The impeller 30 is mounted directly on the output shaft 21 of the pump hydraulic motor assembly. The internal power structure 20, driven by the pressurized oil, drives the output shaft 21 to rotate and drives the impeller 30 to rotate. As the impeller 30 rotates, water is drawn into the intake bell 40 and through the intake bell 40 into the fluid passageway 14. In the water pump structure shown in fig. 2, the impeller 30 is installed at the position where the water inlet bell pipe 40 is connected with the outer cylinder 11, and when the water pump works, water flows from bottom to top and is discharged upwards through the water inlet bell pipe 40 and the fluid passage 14 in sequence.
