Description

Technical Field

[0001] This utility model relates to the field of water pumps, and in particular to a water conveying structure used in a swashplate plunger water pump. Background Technology

[0002] In existing swashplate plunger pumps, the design of the inlet and outlet of the water delivery structure often has some shortcomings. For example, the connection between the inlet and the internal plunger structure is not reasonable enough, resulting in greater resistance when water enters the pump, affecting the pump's delivery efficiency; the outlet lacks an effective filtration device, making it easy for impurities in the water to enter the subsequent water delivery pipeline, causing pipeline blockage or damage to other equipment. Therefore, it is urgent to improve and optimize the inlet and outlet structure of swashplate plunger pumps.

[0003] Therefore, the existing water pump industry needs further improvement. Summary of the Invention

[0004] The purpose of this invention is to provide a water delivery structure for use in a swashplate plunger pump, in order to solve the problems of high resistance to water flow into the pump and lack of effective filtration in the prior art, thereby improving the water delivery efficiency and stability of the pump.

[0005] To achieve the above objectives, the present invention adopts the following solution:

[0006] A water conveying structure applied in a swashplate plunger pump includes a stator assembly and a rotor assembly installed within the stator assembly. The rotor assembly has multiple plunger structures. The stator assembly has a swashplate pressing structure for controlling the alternating reciprocating motion of the multiple plunger structures during rotation. The stator assembly has an inlet on one side and an outlet on the other side. An arc-shaped connecting port is located on one side of the stator assembly, connecting to the inlet and multiple plunger structures. The outlet is connected to one of the plunger structures. A rotating filter structure is located within the outlet.

[0007] Furthermore, the stator assembly includes a fixed valve body, and a front cover is provided at the front end of the fixed valve body.

[0008] Furthermore, the rotor assembly includes a rotor rotatably disposed within the fixed valve body, and a rotation input shaft is rotatably disposed on the front cover, the rotation input shaft being fixedly connected to the rotor.

[0009] Furthermore, multiple plunger structures are evenly distributed around the central axis of the rotor.

[0010] Furthermore, the plunger structure includes a plunger bore and a plunger body movably disposed within the plunger bore.

[0011] Furthermore, the rotating filter structure includes a servo motor disposed on the side wall of the outlet, and a hemispherical filter is disposed at the output end of the servo motor.

[0012] In summary, the advantages of this utility model over the prior art are:

[0013] This invention addresses the shortcomings of existing water pump technologies. Through its structural design, it offers the following advantages, improving water delivery efficiency: The arc-shaped connecting port allows water to flow more smoothly into the plunger structure, reducing resistance and thus increasing delivery efficiency. Effective impurity filtration: The rotating filter structure inside the outlet filters the outflowing water, preventing impurities from entering subsequent water delivery pipes, protecting other equipment, and reducing maintenance costs caused by pipe blockage or equipment damage.

[0019] 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.

[0020] Please see Figures 1-5This utility model provides a water conveying structure applied in a swashplate plunger pump, including a stator assembly 1 and a rotor assembly 2 installed in the stator assembly 1. The rotor assembly 2 is provided with a plurality of plunger structures 3. The stator assembly 1 is provided with a swashplate pressing structure 4 for controlling the reciprocating motion of the plurality of plunger structures 3 in a rotating state. The stator assembly 1 is provided with an inlet 5 on one side and an outlet 6 on the other side. An arc-shaped connecting port 7 is provided on one side inside the stator assembly 1. The arc-shaped connecting port 7 is connected to the inlet 5 and to the plurality of plunger structures 3. The outlet 6 is connected to one of the plunger structures 3. A rotating filter structure 8 is provided inside the outlet 6.

[0021] In this swashplate plunger pump water delivery structure, the various components work together to achieve the water delivery function. When the rotary input shaft 202 starts to rotate under the drive of external force, the rotor 201, which is fixedly connected to the rotary input shaft 202, rotates accordingly. Since the rotor 201 is rotatably installed inside the fixed valve body 101, during its rotation, the swashplate pressing structure 4 in the stator assembly 1 plays a role in controlling the multiple plunger structures 3, which are evenly distributed around the central axis of the rotor 201, to perform alternating reciprocating motion in a rotating state.

[0022] During water transport, water first enters through the inlet 5 on one side of the stator assembly 1. At this point, the arc-shaped connecting port 7 on one side of the stator assembly 1 plays a crucial role, connecting to both the inlet 5 and multiple plunger structures 3. The special design of the arc-shaped connecting port 7 allows the water flow entering through the inlet 5 to be more smoothly distributed into each plunger structure 3. Specifically, the water flows through the arc-shaped connecting port 7 into the plunger holes 301 of the plunger structures 3. As the plunger body 302 reciprocates within the plunger holes 301, the water is compressed within them.

[0023] The compressed water is squeezed out from one of the plunger structures 3 connected to the outlet 6. The rotating filter structure 8 installed inside the outlet 6 filters the outflowing water.

[0024] The servo motor 801 in the rotating filter structure 8 is installed on the side wall of the outlet 6. After a period of time, the hemispherical filter 802 connected to its output end rotates under the drive of the servo motor 801 and stops the water pump. The rotating hemispherical filter 802 flips over, so that the filter material on the other side rotates to the bottom for easy cleaning, while preventing impurities from entering the subsequent water supply pipe, ensuring that the filtered water flows out smoothly from the outlet 6 and enters the subsequent water supply pipe, thus realizing the entire water supply process.

[0025] The stator assembly 1 of this utility model includes a fixed valve body 101, and a front cover 102 is provided at the front end of the fixed valve body 101.

[0026] The rotor assembly 2 of this utility model includes a rotor 201 rotatably disposed within the fixed valve body 101, and a rotation input shaft 202 rotatably disposed on the front cover 102, the rotation input shaft 202 and the rotor 201 being fixedly connected.

[0027] In this invention, multiple plunger structures 3 are evenly distributed around the central axis of the rotor 201.

[0028] The plunger structure 3 of this utility model includes a plunger hole 301 and a plunger body 302 movably disposed within the plunger hole 301.

[0029] The rotating filter structure 8 of this utility model includes a servo motor 801 disposed on the side wall of the water outlet 6, and a hemispherical filter 802 is disposed at the output end of the servo motor 801.
