[0029] Specific as follows:
[0030] The top of the oil tank 10 is provided with a liquid inlet 110, the heating device 20 is fixed on the oil tank 10, and the heating end of the heating device 20 extends into the oil tank 10, the sidewall of the oil tank 10 is also provided with an oil outlet 120 and an oil return port 130, one end of the first flow control component 40 is communicated with the oil outlet 120 through the delivery pipe 30, the other end of the first flow control component 40 is communicated with the oil inlet end of the electronic oil pump 90 through the delivery pipe 30, the first pressure sensor 60 is arranged on the delivery pipe 30 between the first flow control component 40 and the electronic oil pump 90, the oil outlet end of the electronic oil pump 90 is communicated with one end of the second flow control component 50 through the delivery pipe 30, and the second pressure sensor 70 and the flow sensor 80 are arranged on the delivery pipe 30 between the electronic oil pump 90 and the second flow control component 50 in turn from the oil flow direction, the second pressure sensor 70 is arranged close to the electronic oil pump 90, and the other end of the second flow control component 50 is communicated with the oil return port 130 through the delivery pipe 30.
[0031] Specifically, the oil storage tank 10 is used for storing oil, and an oil adding opening 110 is arranged at the top of the oil storage tank 10 to add oil from outside into the oil storage tank 10; the heating device 20 is used for heating the oil in the oil storage tank 10, so that the oil pump performance under different temperature conditions can be monitored, and the heating device 20 is fixed on the oil storage tank 10 and extends into the oil storage tank 10 to be in contact with the oil, so that the heating effect is achieved, preferably, the heating device 20 adopts an electric heating mode, and the oil is heated by converting electric energy into heat energy; the conveying pipe 30 is used as a connecting piece between various components to convey oil, and can adopt a high-pressure hose, which is a pipeline equipment capable of bearing high pressure and is more suitable for the application of the oil pump.
[0032] The oil tank 10 side wall is provided with an oil outlet 120 and an oil return port 130. The oil outlet 120 is used for flowing the oil in the oil tank 10 into the electronic oil pump 90 to be tested through a pipeline. The oil return port 130 is used for collecting the tested oil and flowing it back into the oil tank 10. The first flow control component 40 is used for controlling the oil flow at the oil outlet 120. Therefore, one end of the first flow control component 40 is communicated with the oil outlet 120 through the delivery pipe 30. The oil flowing through the first flow control component 40 is then introduced into the electronic oil pump 90 to be tested. Therefore, the other end of the first flow control component 40 is communicated with the oil inlet end of the electronic oil pump 90 through the delivery pipe 30. The first pressure sensor 60 is used for detecting the pressure at the oil inlet end of the electronic oil pump 90. Therefore, the first pressure sensor 60 is arranged on the delivery pipe 30 between the first flow control component 40 and the electronic oil pump 90, close to the oil inlet end of the electronic oil pump 90. The oil flowing out of the electronic oil pump 90 needs to be returned to the oil tank 10 to ensure the continuous supply and taking of the oil and maintain the oil amount in the oil tank 10, so as to facilitate the testing of the next electronic oil pump 90. Similarly to the first flow control component 40, the second flow control component 50 is arranged at the oil return port 130 to control the oil flow. Therefore, the oil outlet end of the electronic oil pump 90 is communicated with one end of the second flow control component 50 through the delivery pipe 30. The oil flowing through the second flow control component 50 is then returned to the oil tank 10 through the oil return port 130 through the delivery pipe 30. It can be understood that the second pressure sensor 70 and the flow sensor 80 are arranged on the delivery pipe 30 between the electronic oil pump 90 and the second flow control component 50 in sequence from the oil flow direction. Since the second pressure sensor 70 is used for detecting the pressure at the oil outlet end of the electronic oil pump 90, the second pressure sensor 70 needs to be arranged close to the oil outlet end of the electronic oil pump 90. The flow sensor 80 is used for detecting the oil flow. After the components for feeding back the data are installed, the PLC control device can be arranged to collect the data to improve the testing speed, directly feedback and improve the efficiency, so as to obtain the performance test structure through the collected data, thereby realizing the measurement and analysis of the working state parameters of the oil pump.
[0033] Further, after obtaining the real-time data of the electronic oil pump 90, the PLC control device can obtain the performance test structure according to the set formula:

[0040] As a preferred embodiment of the present application, the first flow control assembly 40 and the second flow control assembly 50 both adopt a throttle valve.
[0041] It should be noted that the throttle valve can control the flow of fluid by changing the opening size of the valve, so as to achieve the purpose of adjusting the flow, and has strong adaptability in controlling flow and pressure.
