Therefore, the above terms should not be construed as limitations on this application.

[0056] The present application will now be described in further detail with reference to the accompanying drawings, see below. Figures 1 to 5 illustrate.

[0057] This application provides an electronic oil pump performance testing device (hereinafter referred to as testing device 1), which is used to automatically test the performance of electronic oil pump 2. The tested performance includes the rotational speed, outlet pressure, outlet flow rate and current value of electronic oil pump 2. It comprehensively tests the performance of electronic oil pump 2, so that one testing device 1 can meet the diverse needs of testing electronic oil pump 2, simplify the testing process and improve the detection efficiency.

[0058] Specifically, such as Figures 1 to 2 As shown, the testing device 1 includes a main frame 14, a testing mechanism 11, an oil supply assembly 12, and a controller 13. The testing mechanism 11, the oil supply assembly 12, and the controller 13 are mounted on the main frame 14. The testing mechanism 11 is used to test the rotational speed, outlet pressure, outlet flow rate, and current performance of the electronic oil pump 2. The oil supply assembly 12 is used to provide oil at a specific temperature to the testing mechanism 11 to ensure the stability of the electronic oil pump 2 during testing. The controller 13 is used to control the testing mechanism 11 and the oil supply assembly 12 to operate according to the control program to achieve automated operation. It can automatically monitor and record various parameters without the need for personnel on duty, thus saving labor costs.

[0059] Among them, such as Figure 1 , Figure 2 As shown, the main frame 14 includes a main housing 141, a mounting surface 143, and a control frame 142. The mounting surface 143 is the upper surface of the main housing 141. The main housing 141 is a box-like structure. The control frame 142 is located on the upper part of the main housing 141 and extends upwards, as shown in the figure. Figure 2 As shown, the control frame 142 is connected to the rear end of the main housing 141. The control frame 142 is a frame structure, and the controller 13 is connected to the control frame 142. The test mechanism 11 is set on the mounting platform 143, and the oil supply component 12 is set inside the main housing 141. The controller 13, the test mechanism 11, and the oil supply component 12 are arranged in order from high to low.

[0060] Furthermore, the main frame 14 also includes an oil receiving tray 144, which is located below the electronic oil pump 2, inside the main housing 141, and above the constant temperature oil tank 121. The oil receiving tray 144 is detachably connected to the main housing 141. The oil receiving tray 144 is used to collect the oil leaked during the test by the test mechanism 11, so as to avoid oil waste and oil splashing.

[0061] Based on any of the above embodiments, the testing mechanism 11 will be further described; such as Figures 1 to 3 As shown, the testing mechanism 11 includes a speed detection component, a pressure detection component, a flow detection component, and a current detection component, which sequentially test the speed, outlet pressure, outlet flow rate, and current of the electronic oil pump 2.

[0062] Specifically, such as Figure 3 As shown, the pressure detection component is installed on the oil outlet side of the electronic oil pump 2. The pressure detection component is used to monitor the oil outlet pressure of the electronic oil pump 2. The pressure detection component includes a pressure sensor 111, which can detect the liquid outlet pressure of the electronic oil pump 2. This helps the operator understand the actual working capacity of the electronic oil pump 2 and the working status of the system, so as to understand the reliability and efficiency of the system.

[0063] like Figure 3 As shown, the flow detection component is installed on the oil outlet side of the electronic oil pump 2, and the pressure detection component is used to monitor the liquid flow rate of the electronic oil pump 2. The pressure detection component includes a flow meter 112, which is installed on the oil outlet side of the electronic oil pump 2. This allows for understanding of the delivery capacity of the electronic oil pump 2, the movement speed of the actuator, the load requirements of the system, and the operating efficiency. By accurately controlling and monitoring the liquid flow rate, the system performance can be optimized, efficiency improved, energy consumption reduced, and reliable operation of the equipment ensured.

[0064] The speed detection component is installed on the motor of the electronic oil pump 2 to monitor the motor speed of the electronic oil pump 2. The speed detection component includes a speed sensor connected to the motor of the electronic oil pump 2. By monitoring the speed of the electronic oil pump 2, the speed of the electronic oil pump 2 can be accurately controlled, ensuring that it operates under optimal conditions, reducing energy waste, and accurately controlling the flow rate. It can also play a role in fault diagnosis and early warning, monitoring the operating status of the electronic oil pump 2 in real time, and promptly detecting motor faults for timely maintenance.

[0065] The current detection component is connected to the motor of the electronic oil pump 2 to monitor the current of the electronic oil pump 2. The current detection component includes a current sensor, which is connected to the motor to obtain the motor current of the electronic oil pump 2. This allows the controller 13 to calculate the input power of the electronic oil pump 2 based on the current value. Combined with the liquid flow rate, liquid pressure, and speed, the controller can calculate the efficiency of the motor and adjust the size of the housing of the electronic oil pump 2.

[0066] In another optional embodiment, the current detection component may further include a measuring instrument connected to the motor of the electronic oil pump 2, which calculates the current value based on the voltage value.

[0067] Furthermore, such as Figure 3 As shown, the testing mechanism 11 also includes a speed control valve 113 and a relief valve. Both the speed control valve 113 and the relief valve are located at the oil outlet of the electronic oil pump 2. The speed control valve 113 is used to adjust the oil flow rate of the electronic oil pump 2, accurately control the liquid flow rate of the electronic oil pump 2, realize automatic compensation for the impact of load changes, and improve system stability. The relief valve is used to control the liquid pressure of the electronic oil pump 2, maintain the constant system pressure, and play a safety protection role to prevent the equipment from being damaged due to excessive system pressure. With the cooperation of the speed control valve 113 and the relief valve, the liquid pressure and liquid flow rate of the electronic oil pump 2 can be dually controlled, improving the overall efficiency of the system, enhancing system stability, and reducing the risk of failure.

[0068] Furthermore, the testing organization 11 is described in more detail; such as... Figure 3 As shown, the testing mechanism 11 also includes a mounting base 115 and a fixed base 116. The fixed base 116 is fixedly mounted on the mounting platform 143, and the mounting base 115 is mounted on the fixed base 116. The mounting base 115 and the fixed base 116 are detachably connected. The mounting base 115 is used to install the electronic oil pump 2. In this embodiment, by replacing different mounting bases 115, different specifications of electronic oil pumps 2 can be installed, enabling the testing device 1 to perform performance tests on different electronic oil pumps 2 and improving the flexibility of the testing device 1.

[0069] The mounting platform 143 has an installation port, and the fixed base 116 is located on the side away from the installation port. The installation port is located above the oil supply assembly 12. The oil supply assembly 12 includes a constant temperature oil tank 121 and an oil pipe assembly. The constant temperature oil tank 121 is used to store oil. The constant temperature oil tank 121 is connected to the electronic oil pump 2 through the oil pipe assembly to realize the circulation of oil. The installation port is for the oil supply pipe assembly to pass through.

[0070] Specifically, such as 1 to Figure 3 As shown, the oil pipe assembly includes an inlet pipe 122 and an outlet pipe 123, which are generally arranged in parallel. One end of the inlet pipe 122 is connected to the inlet of the electronic oil pump 2, and the other end is connected to the outlet of the constant temperature oil tank 121, so as to guide the oil in the constant temperature oil tank 121 to the electronic oil pump 2. One end of the outlet pipe 123 is connected to the outlet of the electronic oil pump 2, and the other end is connected to the inlet of the constant temperature oil tank 121, so as to guide the oil flowing out of the electronic oil pump 2 back to the constant temperature oil tank 121. With the cooperation of the inlet pipe 122 and the outlet pipe 123, an oil circulation system is realized.

[0071] Among them, such as Figure 3 As shown, the pressure detection component, speed control valve 113, and flow detection component are sequentially arranged on the oil outlet pipe 123 along the oil outlet direction.

[0072] like Figure 1 As shown, the test mechanism 11 also includes a tubing support 114, which is located below the tubing assembly and is used to support and elevate the tubing assembly.

[0073] Furthermore, the oil supply component 12 is described in more detail; such as Figures 1 to 2 , Figures 4 to 5 As shown, the oil supply assembly 12 also includes a heater, a cooler, and a temperature sensor 126. The heater is installed in the constant temperature oil tank 121 and is used to heat the oil so that the oil can reach the required temperature. The cooler is installed in the constant temperature oil tank 121 and is used to cool the oil so that the oil can reach the required temperature. Under the action of the heater and the cooler, on the one hand, the oil in the constant temperature oil tank 121 can be kept at a constant temperature, and on the other hand, the oil in the constant temperature oil tank 121 can be maintained at different temperature states, so as to test the performance of the electronic oil pump 2 at different temperatures.

[0074] Temperature sensor 126 is installed inside constant temperature oil tank 121. Temperature sensor 126 is used to detect oil temperature, thereby realizing real-time monitoring of oil temperature in constant temperature oil tank 121, so that the staff or controller 13 can adjust the temperature of constant temperature oil tank 121 in a timely manner.

[0075] In this embodiment, both the heater and the cooler can be electric. The controller 13 can receive the temperature information uploaded by the temperature sensor 126 and use it to control the heater and the cooler so that the temperature in the constant temperature oil tank 121 reaches the set value.

[0076] Furthermore, such as Figure 4 As shown, the constant temperature oil tank 121 has a double-layer structure, including an inner liner and an outer shell. There is a gap between the inner liner and the outer shell, which effectively isolates heat transfer and reduces heat loss of the constant temperature oil tank 121. The constant temperature oil tank 121 is equipped with a control panel 124, which is located on the side of the constant temperature oil tank 121. The temperature of the constant temperature oil tank 121 can be set through the control panel 124, which is convenient for operators.

[0077] like Figure 4 As shown, the constant temperature oil tank 121 is equipped with an oil suction filter element 127 and an air filter 125. The oil suction filter element 127 is located between the oil outlet of the constant temperature oil tank 121 and the oil inlet of the oil inlet pipe 122 to filter the oil entering the electronic oil pump 2 and prevent impurities in the oil from entering the electronic oil pump 2.

[0078] like Figure 4 As shown, the air filter 125 is installed on the constant temperature oil tank 121. The air filter 125 is used to filter impurities, dust, particulate matter, and other contaminants from the air entering the constant temperature oil tank 121, preventing contamination of the oil. The air filter 125 also plays a role in balancing the pressure within the constant temperature oil tank 121. When the electronic oil pump 2 is working, the pressure inside the constant temperature oil tank 121 will change. The air filter 125 can prevent vacuum or overpressure in the constant temperature oil tank 121 caused by pressure changes, and prevent the generation of negative or positive pressure within the constant temperature oil tank 121.

[0079] Based on any of the above embodiments, the controller 13 will be further described; such as Figure 1 As shown, the controller 13 includes a control system and a digital display. The digital display is mounted on the main frame 14. The control system can control the oil supply component 12 and the testing mechanism 11, and can receive and record the information uploaded by the oil supply component 12 and the testing mechanism 11, and then generate corresponding information to be displayed on the digital display. The digital display can display the current information of the electronic oil pump 2, the liquid pressure information, the liquid flow information, the electronic speed information, and the temperature information of the constant temperature oil tank 121.

[0080] The control system is connected to the control panel 124, heater, cooler and temperature sensor 126 of the constant temperature oil tank 121, and can be used to control the oil temperature of the constant temperature oil tank 121.

[0081] In addition, controller 13 corresponds to an on / off switch to control the activation of test device 1. It should be noted that the various embodiments of this application can be arbitrarily combined to form new embodiments, provided that the solutions do not conflict and the technical solutions can coexist.

[0082] The present application has been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of the present application. The descriptions of the embodiments above are only for the purpose of helping to understand the present application and its core ideas. It should be noted that those skilled in the art can make several improvements and modifications to the present application without departing from the principles of the present application, and these improvements and modifications also fall within the protection scope of the claims of the present application.
