[0026] This invention also provides a hydraulic component cleaning system, which includes a motor, a hydraulic pump, a reservoir, and a cleaning valve assembly. The motor is connected to the hydraulic pump to drive the hydraulic pump. The inlet of the hydraulic pump is connected to the reservoir, and the outlet of the hydraulic pump is connected to the cleaning valve assembly. The hydraulic component cleaning system further includes:

[0041] Detailed Implementation

[0042] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0043] It should be noted that, unless otherwise specified, the embodiments and features described in this invention can be combined with each other.

[0044] In this invention, unless otherwise stated, directional terms such as "upper," "lower," "top," and "bottom" are generally used to describe the relative positions of components in relation to the directions shown in the accompanying drawings or in relation to the vertical, perpendicular, or gravitational directions.

[0045] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0046] This invention first provides a method for cleaning hydraulic components.

[0047] In one implementation, refer to the appendix. Figure 1 As shown, the cleaning methods for hydraulic components include:

[0048] Determine the component type of the hydraulic components to be cleaned;

[0049] Determine the component parameters or specifications of the hydraulic components to be cleaned based on the identified component types.

[0050] The corresponding cleaning pressure is determined based on the identified component type, component parameters or component specifications and a pre-set correspondence. Specifically, the correspondence between component type, component parameters or component specifications and cleaning pressure can be obtained through statistical analysis of multiple cleaning tests of hydraulic components.

[0051] Determine the cleaning time;

[0052] Clean the hydraulic components to be cleaned according to the determined cleaning time and cleaning pressure.

[0053] Understandably, before cleaning hydraulic components, the type, specifications, or parameters of the components to be cleaned are determined. Based on the determined component type, parameters, or specifications, a corresponding cleaning pressure is determined according to a pre-set correspondence. The hydraulic components are then cleaned according to the determined cleaning pressure. This setup, which sets specific cleaning pressures for different types, specifications, or parameters of hydraulic components, can greatly improve the cleaning effect of hydraulic components and avoid residual contaminants on the cleaned hydraulic components, which could seriously affect the cleanliness of the hydraulic system using the hydraulic components. At the same time, the precise use of cleaning fluid can avoid resource waste.

[0054] In one implementation, determining the component type of the hydraulic component to be cleaned includes:

[0055] The component type of the hydraulic component to be cleaned is determined based on the user's input instructions. The component types include steel pipes, hoses, valve blocks, connectors, oil tanks, and others. In other words, the user determines the component type of the hydraulic component to be cleaned and then inputs the corresponding component type selection instruction to determine the component type.

[0056] In other embodiments, a type detection device can be set up to detect the component type of the hydraulic component to be cleaned to determine the component type. For example, the type detection device has pre-stored feature information of multiple component types. The feature information of the hydraulic component to be cleaned is obtained by visual recognition. By comparing the obtained feature information of the hydraulic component to be cleaned with the feature information of multiple pre-stored component types, the component type of the hydraulic component to be cleaned is determined, thereby automating the determination of the component type of the hydraulic component to be cleaned.

[0057] In one embodiment, determining the component parameters or specifications of the hydraulic component to be cleaned based on the determined component type includes:

[0058] When the determined component type is a steel pipe or a rubber hose, the component parameters of the hydraulic component to be cleaned are determined according to the user's input instructions. The component parameters include the pipe diameter and length. That is, the user determines the pipe diameter and length of the hydraulic component to be cleaned, and then inputs the corresponding pipe diameter and length setting instructions to determine the pipe diameter and length information of the hydraulic component to be cleaned. In other embodiments, a parameter detection device can be set to detect the component parameters of the hydraulic component to be cleaned to determine the component parameters. For example, the parameter detection device uses visual recognition to directly measure the pipe diameter and length of the hydraulic component to be cleaned, thereby determining the pipe diameter and length of the hydraulic component to be cleaned, and realizing the automation of the determination of the component parameters of the hydraulic component to be cleaned.

[0059] When the identified component type is a valve block, connector, oil tank, or others, the component specifications of the hydraulic component to be cleaned are determined according to the user's input instructions. In other words, the user determines the component specifications of the hydraulic component to be cleaned and then inputs the corresponding component specification setting instructions, thereby determining the component specifications. It can be understood that, for example, valve blocks, connectors, oil tanks, and other hydraulic components are all standard parts. When the user makes an actual judgment, it is easy to determine the component specifications based on the model of the hydraulic component to be cleaned. In other embodiments, a specification detection device can be set up to detect the component specifications of the hydraulic component to be cleaned to determine the component specifications. For example, the specification detection device pre-stores feature information of various component specifications. The feature information of the hydraulic component to be cleaned is obtained through visual recognition. By comparing the obtained feature information of the hydraulic component to be cleaned with the feature information of the pre-stored various component specifications, the component specifications of the hydraulic component to be cleaned are determined, thereby automating the determination of the component specifications of the hydraulic component to be cleaned.

[0060] In one implementation, determining the cleaning time includes:

[0061] When the determined component type is steel pipe or rubber hose, the corresponding cleaning time is determined based on the determined component type and component parameters according to the preset correspondence. Specifically, the correspondence between component type and component parameters or component specifications and cleaning time can be obtained by statistical analysis of multiple cleaning tests of hydraulic components.

[0062] When the determined component type is valve block, connector, oil tank, or others, the cleaning time is determined according to the user's input instructions, or the corresponding cleaning time is determined based on the determined component type and component parameters according to a preset correspondence.

[0063] Understandably, when the identified component types are valve blocks, connectors, oil tanks, and others, and the hydraulic components to be cleaned have complex structural shapes, determining the cleaning time through user-input instructions is a more accurate way to meet actual cleaning requirements.

[0064] In one embodiment, the hydraulic component cleaning method further includes:

[0065] After the hydraulic components to be cleaned are cleaned, they are dried using a blow gun. This ensures that no cleaning fluid remains on the hydraulic components after cleaning, thus preventing the hydraulic oil in the hydraulic system using these components from being contaminated by the residual cleaning fluid.

[0066] In one embodiment, the hydraulic component cleaning method further includes:

[0067] After the hydraulic components have been dried, their cleanliness is checked to ensure that no cleaning fluid or contaminants remain on them.

[0068] Specifically, the cleanliness of hydraulic components can be inspected using an endoscope. The endoscope is an existing technology product. By inserting the endoscope into the interior of the hydraulic component, the cleanliness of the hydraulic component can be observed.

[0069] Specifically, when the hydraulic components are steel pipes or rubber hoses, the cleanliness of the hydraulic components can be checked using a purge gun and foam bullets. Specifically, foam bullets are injected into one end of the hydraulic component using a purge gun and retrieved from the other end. The cleanliness of the retrieved foam bullets is then checked to determine the cleanliness of the hydraulic component to be cleaned. This method is quite ingenious and can effectively check hydraulic components with small internal dimensions that cannot be inserted by an endoscope.

[0070] The present invention also provides a hydraulic component cleaning system.

[0071] In one implementation, refer to the appendix. Figure 2 As shown, the hydraulic component cleaning system includes a motor 1, a hydraulic pump 2, a reservoir 3, and a cleaning valve assembly 4. The motor 1 is connected to the hydraulic pump 2 to drive the hydraulic pump 2 to operate. The inlet of the hydraulic pump 2 is connected to the reservoir 3, and the outlet of the hydraulic pump 2 is connected to the cleaning valve assembly 4. Understandably, the reservoir 3 is used to store cleaning fluid. The motor 1 drives the hydraulic pump 2 to operate, which can pump the cleaning fluid in the reservoir 3 to the cleaning valve assembly 4. The cleaning valve assembly 4 then sprays the cleaning fluid onto the hydraulic components to be cleaned, thereby achieving the cleaning of the hydraulic components.

[0072] The hydraulic component cleaning system also includes:

[0073] The first determining module is used to determine the component type of the hydraulic components to be cleaned.

[0074] The second determining module is used to determine the component parameters or component specifications of the hydraulic components to be cleaned based on the determined component type.

[0075] The third determining module is used to determine the corresponding cleaning pressure based on the determined component type and component parameters or component specifications according to a preset correspondence.

[0076] The fourth module is used to determine the cleaning time;

[0077] The control module is used to control the operation of motor 1 and hydraulic pump 2 according to the determined cleaning time and cleaning pressure, so as to clean the hydraulic components to be cleaned.

[0078] Understandably, motor 1 drives hydraulic pump 2 to pump the cleaning fluid in storage tank 3 to cleaning valve group 4, from which cleaning fluid is sprayed to clean the hydraulic components. The control module determines the operating parameters of motor 1 and hydraulic pump 2 according to the determined cleaning time and cleaning pressure. By controlling the operation of motor 1 and hydraulic pump 2 according to the operating parameters, the actual cleaning time and cleaning pressure can be controlled to be consistent with the determined cleaning time and cleaning pressure.

[0079] Specifically, motor 1 can be a variable frequency motor or a servo motor, and hydraulic pump 2 can be a vane pump or a piston pump. In this way, the control module can more accurately control the cleaning time and cleaning pressure by controlling the operation of motor 1 and hydraulic pump 2.

[0080] Furthermore, a high-pressure filter can be connected between the outlet of the hydraulic pump 2 and the cleaning valve assembly 4. With this configuration, the cleaning fluid delivered to the cleaning valve assembly 4 can be ensured to have good cleanliness through the filtration effect of the high-pressure filter, thus avoiding secondary contamination of the hydraulic components by the cleaning fluid sprayed out by the cleaning valve assembly 4.

[0081] Furthermore, the hydraulic component cleaning system may also include a proportional relief valve, which is connected between the hydraulic pump 2 and the high-pressure filter to limit the pressure. The control module is also used to control the working state of the proportional relief valve according to the determined cleaning pressure.

[0082] In one embodiment, the first determining module is specifically used to determine the component type of the hydraulic component to be cleaned according to the instructions input by the user, wherein the component type includes steel pipe, rubber hose, valve block, connector, oil tank and others.

[0083] In one embodiment, the second determining module is specifically used to determine the component parameters of the hydraulic component to be cleaned according to the user input instruction when the determined component type is a steel pipe or a rubber hose. The component parameters include pipe diameter and length. When the determined component type is a valve block, connector, oil tank, or others, the module determines the component specifications of the hydraulic component to be cleaned according to the user input instruction.

[0084] In one embodiment, the fourth determining module is specifically used to determine the corresponding cleaning time based on a preset correspondence relationship when the determined component type is a steel pipe or a rubber hose; when the determined component type is a valve block, connector, oil tank, or others, it determines the cleaning time based on the user input instruction, or determines the corresponding cleaning time based on a preset correspondence relationship based on the determined component type and component parameters.

[0085] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. 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.

[0086] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, the present invention will not describe the various possible combinations separately.

[0087] Furthermore, various different embodiments of the present invention can be combined in any way, as long as they do not violate the spirit of the present invention, they should also be regarded as the content disclosed by the present invention.
