Description

TECHNICAL FIELD

[0001] The utility model relates to oil pump motor performance test technical field, especially relates to a kind of oil pump motor test system. BACKGROUND

[0002] In the traditional oil pump motor performance test, in order to accurately measure power, torque and speed and other key indicators, engineers have to rely on a variety of professional equipment. These devices are independent of each other, and each has its specific operating procedures and calibration requirements, which means that the operator not only needs to master the working principle of different devices, but also needs to spend a lot of time on switching between devices and data synchronization, resulting in an extremely cumbersome test process.

[0003] Due to the dispersion of various devices and technical means, the existing test method often cannot provide an integrated solution, which greatly reduces the test efficiency. For example, in a batch production environment, each motor needs to go through a series of rigorous functional tests, which not only consumes valuable time resources, but also increases the possibility of human error. In addition, the complex setup process and high requirement for professional knowledge limit the participation ability of non-expert users, further slowing down the pace of research and production. Therefore, the industry calls for the development of a comprehensive test system that can simplify the operation process, improve the automation level and handle multiple test tasks simultaneously to improve test efficiency and reduce costs.

[0029] Figure 1 A structural block diagram of an oil pump motor test system provided by one exemplary embodiment of the present application is shown.Figure 2 A structural schematic diagram of a test table of an oil pump motor test system is shown, and the oil pump motor test system comprises: a cabinet 1 and a test table 2, the cabinet 1 comprises an industrial computer 11, an acquisition instrument 12 and a program-controlled power supply 13, the industrial computer 11 and the acquisition instrument 12 are both electrically connected with the program-controlled power supply 13, and the industrial computer 11 is in communication connection with the program-controlled power supply 13 and the acquisition instrument 12; the test table 2 comprises a hysteresis dynamometer 21 as a load, the hysteresis dynamometer 21 is in driving connection with a measured oil pump motor through a torque and speed sensor 22, the hysteresis dynamometer 21, the torque and speed sensor 22 and the measured oil pump motor are all electrically connected with the program-controlled power supply 13, the torque and speed sensor 22 is in communication connection with the acquisition instrument 12, and the hysteresis dynamometer 21 is in communication connection with the industrial computer 11.

[0030] In the embodiment of the present application, the hysteresis dynamometer 21 is used as a load to simulate the resistance applied to the measured oil pump motor under actual working conditions. The hysteresis dynamometer 21 can provide stable torque load and can accurately control the load size at different speeds.

[0031] In the embodiment of the present application, the torque and speed sensor 22 is used to detect the torque and speed of the measured oil pump motor. The sensor is one of the core parts of the measurement system, which can monitor and output the torque and rotational speed data generated by the measured oil pump motor in real time, and feed back to the industrial computer 11 through the acquisition instrument 12.

[0032] In the embodiment of the present application, the industrial computer 11 is the core control unit of the whole test system, responsible for running the host computer test software, processing data from the acquisition instrument 12, and communicating with the program-controlled power supply 13. It can not only monitor and record the performance indicators of the motor in real time, but also automatically adjust the load and other parameters according to the preset test program. In addition, the industrial computer 11 also undertakes the tasks of data storage, analysis and report generation.

[0033] In the embodiment of the present application, the acquisition instrument 12 is mainly used to collect physical signals from the torque and speed sensor 22, and convert these analog signals into digital signals for the industrial computer 11 to process.

[0034] In the embodiment of the present application, the program-controlled power supply 13 is used to provide adjustable voltage and current output to the measured oil pump motor and the hysteresis dynamometer 21. Through the communication connection with the industrial computer 11, the program-controlled power supply 13 can dynamically adjust the power supply parameters according to the test requirements, so as to realize the simulation test of the motor under different working conditions.

[0035] In the embodiment of the present application, the power to be tested of the measured oil pump motor is divided into mechanical power and electric power, and the mechanical power is converted from the torque and speed of the measured oil pump motor measured by the torque and speed sensor 22 according to the industrial computer 11 (specifically, P机 = ω / 60 x 2 x 3.14 x τ, where τ represents torque and ω represents rotational speed). Electrical power is converted by the industrial computer 11 from the voltage and current provided by the programmed power supply 13 (specifically, P 电 = V x I, where V is voltage and I is current).

The transition seat 24 provides a flexible connection method for the torque and speed sensor 22, which can adapt to different models of oil pump motors. The measured oil pump motor is fixed on the second hand sliding table 26 through the measured motor mounting bracket 25, and the second hand sliding table 26 can move along the Y-axis direction to further adjust the position. The entire second hand sliding table 26 is installed on a hand lifting platform 27 which can be adjusted along the Z-axis direction, which allows fine adjustment in three-dimensional space, ensuring that all components are coaxially arranged to reduce unnecessary vibration and error, thereby ensuring high precision and reliability of the test results.

[0038] Further, referring to Figure 2 , the test base 28 is installed with universal wheels 29 at the bottom, which improves the flexibility of the entire oil pump motor test system.

[0039] It can be understood that, referring to Figure 1 ​The cabinet 1 further comprises a display screen 14, which is in communication connection with the industrial computer 11 and in electrical connection with the program-controlled power supply 13, which means that it can display in real time the data information processed by the industrial computer 11, such as the equipment running state, parameter setting and alarm information, so as to facilitate the monitoring and adjustment of the operator.
