[0025] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all the other embodiments obtained by those of ordinary skill in the art without creative effort belong to the scope of protection of the present application.

However, those of ordinary skill in the art will realize that the technical solutions of the present application can be practiced without one or more of the specific details, or with other methods, components, devices, steps, etc. In other cases, well-known methods, devices, implementations or operations are not shown or described in detail to avoid obscuring the aspects of the present application.

That is, these functional entities can be implemented in the form of software, or in one or more hardware modules or integrated circuits, or in different networks and / or processor devices and / or microcontroller devices.

[0028] The flow chart shown in the drawing is only an exemplary illustration, and is not necessarily to include all the contents and operations / steps, nor is it necessarily to be executed in the order as described. For example, some operations / steps can be further decomposed, and some operations / steps can be combined or partially combined, so the actual execution order can be changed according to the actual situation.

[0029] Referring to Figure 1 , a hydraulic principle schematic diagram of the servo valve and the proportional valve in the embodiment of the present application is shown. The hydraulic principle schematic diagram includes multiple oil pumps, multiple reversing valves, and test valves (i.e. servo valves and proportional valves). In the present application, when analyzing and judging the inner leakage flow signal curve of the servo valve and the proportional valve, the relationship between the flow of the hydraulic oil in the servo valve and the proportional valve and the current can be obtained, i.e. the inner leakage flow signal curve and the flow signal curve of each throttle port can be obtained, by controlling the oil pump MA2, the state of each reversing valve, and different control signals. Then, by analyzing the flow signal curve of each throttle port and the conduction condition and flow in the servo valve and the proportional valve, the accuracy of the inner leakage flow signal curve can be judged, so that the manufacturing precision of the servo valve and the proportional valve can be judged. At the same time, the neutral function of the servo valve and the proportional valve can also be judged.

[0030] Next, the present application will be described in detail:

[0031] Figure 2 A flow chart of the inner leakage flow signal curve judgment method in the embodiment of the present application is shown. The inner leakage flow signal curve judgment method can be executed by a device with a calculation processing function, such as an inner leakage flow signal curve judgment device. Referring to Figure 2 , the inner leakage flow signal curve judgment method at least includes steps 210 to 230, which are described in detail as follows:

[0032] Step 210, by switching the flow meter reversing valve to a small flow meter and closing the reversing valves except the flow meter reversing valve, the rated positive value and the rated negative value of the control signal are obtained, so that the inner leakage flow signal curve is obtained.

[0033] Step 220, for different throttle ports, by controlling the state of each reversing valve, the rated positive value and the rated negative value of the control signal are obtained, so that the corresponding throttle port flow signal curve is obtained.

[0034] Step 230, according to the throttle port flow signal curve, the accuracy of the inner leakage flow signal curve is judged.

[0035] In the present application, there are four throttles in the servo valve and the proportional valve, which are P, T, A, and B. By controlling the current signals in the servo valve and the proportional valve, the conduction between different throttles can be controlled. Before obtaining the internal leakage flow signal curve and the flow signal curves of each throttle, the test conditions need to be set in advance. The test conditions include pressure, ambient temperature, control signal adjustment range (current signal in the present application), hydraulic oil temperature, hydraulic oil type, hydraulic oil cleanliness, and hydraulic oil kinematic viscosity. After setting the test conditions, the internal leakage flow signal curve and the flow signal curves of each throttle can be obtained by controlling the states of different reversing valves and the sizes of control signals.

[0036] Specifically, the obtaining of the internal leakage flow signal curve can refer to Figure 1 The flowmeter reversing valve is switched to the small flowmeter, the A reversing valve, the B reversing valve, the T reversing valve, the PA reversing valve, the PB reversing valve, the AT reversing valve, and the BT reversing valve are closed, and the current signals of the servo valve and the proportional valve are controlled, so as to obtain the internal leakage flow signal curve.

[0037] Further, in the present application, for different throttles, the rated positive value and the rated negative value of the control signal are obtained by controlling the states of the reversing valves, so as to obtain the corresponding throttle flow signal curve. The throttle flow signal curve can include the P-A throttle flow signal curve, the P-B throttle flow signal curve, the A-T throttle flow signal curve, and the B-T throttle flow signal curve.

[0038] Specifically, the obtaining of the P-A throttle flow signal curve can include the following steps: the A reversing valve, the T reversing valve, and the AT reversing valve are opened, the flowmeter reversing valve is switched to the large flowmeter, and the B reversing valve, the BT reversing valve, the PA reversing valve, and the PB reversing valve are closed. Then, the corresponding P-A throttle flow signal curve is obtained by obtaining the rated positive value and the rated negative value of the control signal.

[0039] Specifically, the obtaining of the P-B throttle flow signal curve can include the following steps: the B reversing valve, the T reversing valve, and the BT reversing valve are opened, the flowmeter reversing valve is switched to the large flowmeter, and the A reversing valve, the AT reversing valve, the PA reversing valve, and the PB reversing valve are closed. Then, the corresponding P-B throttle flow signal curve is obtained by obtaining the rated positive value and the rated negative value of the control signal.

[0040] Specifically, the A-T throttle port flow signal curve can be obtained by the following steps: opening the A directional valve and the PA directional valve, switching the flowmeter directional valve to the large flowmeter, and closing the B directional valve, the T directional valve, the PB directional valve, the AT directional valve, and the BT directional valve. Then, the A-T throttle port flow signal curve is obtained by acquiring the rated positive value and the rated negative value of the control signal.

[0041] Specifically, the B-T throttle port flow signal curve can be obtained by the following steps: opening the B directional valve and the PB directional valve, switching the flowmeter directional valve to the large flowmeter, and closing the A directional valve, the T directional valve, the PA directional valve, the AT directional valve, and the BT directional valve. Then, the B-T throttle port flow signal curve is obtained by acquiring the rated positive value and the rated negative value of the control signal.

[0042] Further, after obtaining the inner leakage flow signal curve, the P-A throttle port flow signal curve, the P-B throttle port flow signal curve, the A-T throttle port flow signal curve, and the B-T throttle port flow signal curve, the accuracy of the inner leakage flow signal curve can be judged.

[0043] For example, if the P-A throttle port flow signal curve and the P-B throttle port flow signal curve exist at the same time under the same control signal, it indicates that the servo valve and the proportional valve core valve sleeve are worn or have poor machining precision, causing the overlap to be too small, so that the inner leakage flow signal curve is judged to be accurate.

[0044] For another example, if the P-A throttle port flow signal curve and the B-T throttle port flow signal curve are gradually increased in control signal, the B-T throttle port flow is first turned on, and the P-A throttle port flow is turned on later, it indicates that the B-T valve core valve sleeve overlap is greater than P-A, and the reason why the B-T valve core valve sleeve overlap is greater than P-A is that the servo valve and the proportional valve core valve sleeve have poor machining precision, so that the inner leakage flow signal curve is judged to be inaccurate.

[0045] For another example, if the P-B throttle port flow signal curve and the A-T throttle port flow signal curve are gradually increased in control signal, the A-T throttle port flow is first turned on, and the P-B throttle port flow is turned on later, it indicates that the A-T valve core valve sleeve overlap is greater than P-B, and the reason why the A-T valve core valve sleeve overlap is greater than P-B is that the servo valve and the proportional valve core valve sleeve have poor machining precision, so that the inner leakage flow signal curve is judged to be inaccurate.

[0046] Further, the application can judge the accuracy of the inner leakage flow signal curve and the mid-position function of the servo valve and the proportional valve by the inner leakage flow signal curve, the P-A throttle flow signal curve, the P-B throttle flow signal curve, the A-T throttle flow signal curve and the B-T throttle flow signal curve.

[0047] Specifically, when the control signal is zero, the mid-position function of the servo valve and the proportional valve is judged according to the flow output of each throttle flow signal curve.
