Description

Technical Field

[0001] This utility model relates to the field of hydraulic motor cooling technology, and in particular to a hydraulic motor cooling device. Background Technology

[0002] A hydraulic motor is a device that converts hydraulic energy into rotational mechanical energy. Its working principle is mainly based on the high-pressure fluid provided by the hydraulic system driving the rotor to generate rotational motion. Specifically, a hydraulic motor contains a rotor and a stator. After the high-pressure fluid enters the motor, it causes the rotor to rotate and transmits energy to the mechanical device through the shaft, thereby driving the mechanical equipment to work normally.

[0003] Hydraulic motors generate a lot of heat during operation. To cool them down quickly, cold air is usually used. However, during the cold air blowing process, particulate impurities are easily carried. If these impurities adhere to the hydraulic motor, they can damage the device and affect its stable operation.

[0004] Existing hydraulic motor cooling fan grilles typically use filter cloth to filter impurities in the air. During the operation of the hydraulic motor, the filter cloth needs to be replaced after a period of use, which to some extent affects the cooling efficiency of the hydraulic motor. Utility Model Content

[0005] The main objective of this invention is to provide a hydraulic motor cooling device that effectively solves the problems in the prior art by providing a detachable filter cartridge and a valve that can continuously or discontinuously discharge impurities.

[0006] To achieve the above objectives, this utility model provides a hydraulic motor cooling device, including a cover, a cooling pipe, an air outlet plate, and a filter box;

[0007] A curved pipe is connected to one side of the cover;

[0008] The cooling pipe is installed inside the housing and is used to cool the gas inside the housing;

[0009] The air outlet plate is installed on the side of the cooling pipe away from the bend;

[0010] The filter box is mounted on the bend. The filter box includes a box body, a filter cartridge, a spring, and a valve. One side of the box body is open, and a valve is installed on the open side of the box body. The filter cartridge is mounted on one side of the valve via the spring. One side of the filter cartridge is connected to an air inlet pipe, which passes through the box body. One side of the box body is connected to an air outlet pipe, which is located on the side of the filter cartridge away from the spring, and the air outlet pipe is connected to the bend.

[0011] Based on the above technical solution, the present invention can be further improved as follows.

[0012] Furthermore, the cooling pipe is arranged in a serpentine shape, and cooling liquid flows inside the cooling pipe. The two ends of the cooling pipe are respectively connected to an inlet pipe and an outlet pipe, and the inlet pipe and the outlet pipe penetrate the cover.

[0013] Furthermore, the spring is detachably connected to both the filter cartridge and the housing. When the filter cartridge is installed in the housing via the spring, the spring is in a stretched state.

[0014] Furthermore, the outer wall of the filter cartridge is spaced apart from the inner wall of the box body.

[0015] The beneficial effects of this utility model are as follows: This utility model provides a hydraulic motor cooling device, which has the following advantages:

[0016] 1. This utility model, by setting up a filter box, allows gas to enter the inner cavity of the filter cartridge from the air inlet pipe and flow from inside the filter cartridge to the outside. Larger impurities in the gas fall into the third cavity, while the filter cartridge filters the gas, thus ensuring that the gas reaching the first cavity is pure gas. This solves the problem that during the cold air blowing process, particulate impurities are easily carried, and if the impurities adhere to the hydraulic motor, they can cause damage to the hydraulic motor.

[0017] 2. This utility model, by setting a filter cartridge and a valve, allows impurities in the second and third cavities to be discharged from the opening side of the box body through the valve, without requiring the cooling fan grille to stop operating. This solves the problem that existing cooling fan grilles cannot replace the filter cloth when cooling the hydraulic motor, thus affecting the working efficiency of the hydraulic motor.

[0027] like Figure 1-3 As shown, this utility model provides a hydraulic motor cooling device, including a cover 1, a cooling pipe 4, an air outlet plate 3, and a filter box 5;

[0028] A bent pipe 2 is connected to one side of the cover 1;

[0029] The cooling pipe 4 is installed inside the housing 1. The cooling pipe 4 is used to cool the gas inside the housing 1. The cooling pipe 4 is arranged in a serpentine shape. Cooling liquid flows inside the cooling pipe 4. The two ends of the cooling pipe 4 are respectively connected to the liquid inlet pipe 6 and the liquid outlet pipe 7. The liquid inlet pipe 6 and the liquid outlet pipe 7 penetrate the housing 1.

[0030] In this embodiment, the inlet pipe 6 and the outlet pipe 7 are respectively connected to an external liquid supply device and a liquid storage device, and the gas inside the casing 1 is cooled by the continuously flowing coolant.

[0031] The air outlet plate 3 is installed on the side of the cooling pipe 4 away from the bend 2;

[0032] The filter box 5 is installed on the bend 2. The filter box 5 includes a box body 8, a filter cartridge 9, a spring 10, and a valve 11. One side of the box body 8 is open, and the valve 11 is installed on the open side of the box body 8. The filter cartridge 9 is installed on one side of the valve 11 via the spring 10. One side of the filter cartridge 9 is connected to an air inlet pipe 12, and the air inlet pipe 12 passes through the box body 8. One side of the box body 8 is connected to an air outlet pipe 13, and the air outlet pipe 13 is located on the side of the filter cartridge 9 away from the spring 10, and the air outlet pipe 13 is connected to the bend 2.

[0033] In this embodiment, the spring 10 is detachably connected to the filter cartridge 9 and the box body 8 respectively. When the filter cartridge 9 is installed in the box body 8 through the spring 10, the spring 10 is in a stretched state, and the outer wall of the filter cartridge 9 is spaced apart from the inner wall of the box body 8.

[0034] In this embodiment, the inner cavity of the box body 8 is sequentially configured as a first cavity 14, a second cavity 15 and a third cavity 16. An air outlet pipe 13 is connected to one side of the first cavity 14. The filter cartridge 9 is located in the second cavity 15 and the spring 10 is located in the third cavity 16. The diameter of the second cavity 15 is larger than the diameter of the first cavity 14 and the third cavity 16.

[0035] In this embodiment, the air inlet pipe 12 is connected to an air extraction device. The gas enters the filter box 5 from the air inlet pipe 12 for filtration. The filtered pure gas enters the bend pipe 2 from the air outlet pipe 13 and is transported to the housing 1 through the bend pipe 2. Under the cooling effect of the cooling pipe 4, the cooled pure gas is blown to the surface of the hydraulic motor through the air outlet plate 3, thereby cooling the hydraulic motor.

[0036] In this embodiment, gas enters the inner cavity of the filter cartridge 9 from the inlet pipe 12 and flows from inside the filter cartridge 9 to outside the filter cartridge 9. The gas is filtered by the filter cartridge 9 to ensure that the gas reaching the first cavity 14 is pure gas.

[0037] Furthermore, when the gas flows into the inner cavity of the filter cartridge 9, larger impurities in the gas fall into the third cavity 16;

[0038] Furthermore, impurities in the second cavity 15 and the third cavity 16 can be discharged through valve 11 without stopping the cooling fan, thus solving the problem that the existing cooling fan cannot replace the filter cloth when cooling the hydraulic motor, which affects the working efficiency of the hydraulic motor.

[0039] The working principle is as follows:

[0040] Gas enters the inner cavity of filter cartridge 9 through inlet pipe 12. Larger impurities in the gas fall into the third cavity 16 and are filtered by filter cartridge 9, ensuring that the gas reaching the first cavity 14 is pure gas. The filtered pure gas enters the bend pipe 2 through outlet pipe 13 and is then transported to the housing 1. Under the cooling effect of cooling pipe 4, the cooled pure gas is blown onto the surface of the hydraulic motor through air outlet plate 3, thereby cooling the hydraulic motor. Impurities in the second cavity 15 and the third cavity 16 can be discharged from the opening side of the box 8 through valve 11, without the need for the cooling air grid to stop operating. This solves the problem that the filter cloth cannot be replaced when the existing cooling air grid is cooling the hydraulic motor, which affects the working efficiency of the hydraulic motor.

Those skilled in the art can readily implement this utility model based on the accompanying drawings and the above description. However, any modifications, alterations, or equivalent variations made by those skilled in the art without departing from the scope of the utility model's technical solution, utilizing the disclosed technical content, are considered equivalent embodiments of this utility model.
