Description

Technical Field

[0001] The invention relates to a cooling channel structure of an all-in-one high-pressure cleaning machine housing, belonging to the technical field of cleaning pumps. Background Art

[0002] A cleaning machine is a machine that conveys fluid or pressurizes fluid. It transfers the mechanical energy of the prime mover or other external energy to the liquid, increasing the energy of the liquid. Cleaning machines are mainly used to convey liquids such as water, oil, acid and alkali liquids, emulsions, suspensions and liquid metals, and can also convey liquid-gas mixtures and liquids containing suspended solids.

[0003] Before the cleaning machine is started, the cleaning machine housing is filled with the liquid to be transported; after starting, the impeller is driven by the shaft to rotate at high speed, and the liquid between the blades must also rotate with it. Under the action of centrifugal force, the liquid is thrown from the center of the impeller to the outer edge and gains energy, leaving the outer edge of the impeller at high speed and entering the volute cleaning machine housing. In the volute, the liquid slows down due to the gradual expansion of the flow channel, and part of the kinetic energy is converted into static pressure energy, and finally flows into the discharge pipe at a higher pressure and is sent to the required place. When the liquid flows from the center of the impeller to the outer edge, a certain vacuum is formed in the center of the impeller. Since the pressure above the liquid surface in the storage tank is greater than the pressure at the inlet of the cleaning machine, the liquid is continuously pressed into the impeller. It can be seen that as long as the impeller keeps rotating, the liquid will be continuously sucked in and discharged.

[0004] When the cleaning machine is running, the motor and controller will heat up rapidly. However, the high temperature environment is not conducive to the stable operation of the cleaning machine. Summary of the invention

[0005] The object of the present invention is to provide a cooling flow channel structure for the housing of an all-in-one high-pressure cleaning machine, which cools the motor and controller of the cleaning machine by taking in water. The cooling water enters the pump body after cooling and is discharged through the water outlet of the pump body, thereby reducing the temperature of the motor and controller of the cleaning machine without adding peripherals.

[0006] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0007] A multi-in-one high-pressure cleaning machine shell cooling flow channel structure is located in the cleaning machine shell, the cleaning machine shell has a motor and a controller, and the cleaning machine shell has a cooling flow channel; the water outlet of the cooling flow channel is connected to the low-pressure side of the cleaning machine, the water inlet of the cooling flow channel is located on the cleaning machine shell, and the cooling flow channel is located in the cleaning machine shell at the motor and controller position.

[0008] In the aforementioned all-in-one high-pressure cleaning machine housing cooling flow channel structure, the cleaning machine housing includes a gear box front cover, an intermediate housing, a gear box rear cover and a controller housing, the gear box front cover is installed on one side of the intermediate housing, the gear box rear cover is installed on the other side of the intermediate housing, and the controller housing is installed on the gear box rear cover; the intermediate housing is provided with a through groove, and the through groove, the gear box front cover and the gear box rear cover cooperate to form a cooling flow channel, and the water inlet of the cooling flow channel is located on the intermediate housing.

[0009] In the aforementioned all-in-one high-pressure cleaning machine shell cooling channel structure, the following method is used to cool the motor and controller: water is introduced into the cooling channel through the water inlet of the cooling channel, and the water in the cooling channel flows through the cleaning machine shell of the motor and controller, taking away the heat generated by the motor and controller, and entering the low-pressure side of the cleaning machine pump body, and is discharged from the water outlet of the cleaning machine under the action of the pump body.

[0010] Compared with the prior art, the present invention cools down the motor and controller of the cleaning machine through water intake from a water source. The cooling water enters the pump body after cooling and is discharged through the water outlet of the pump body, thereby reducing the temperature of the motor and controller of the cleaning machine without adding peripherals.
