Description

Technical Field

[0001] This utility model relates to an energy storage type oil pump temperature test bench. Background Technology

[0002] With the continuous development of science and technology and modern industry, the massive consumption of non-renewable energy and its environmental damage have made countries around the world aware of this problem and are vigorously promoting energy conservation and environmental protection. Countries worldwide are actively developing green transportation tools such as new energy vehicles. The performance and safety reliability of the power battery system, power motor system, control system, and some important components—the core components of new energy vehicles—directly determine the development direction and future of new energy transportation tools.

[0003] To ensure that products can achieve their maximum performance and reliability while maintaining safety and energy efficiency, extensive testing is required to simulate their worst operating conditions and the most demanding and extreme testing conditions. The entire testing process involves the development, design, manufacturing, and inspection processes.

[0004] As a component of mechanical parts, the oil pump provides fluid for lubrication. Its performance directly affects the service life and operational stability of core components, ensuring the reliable operation of power assemblies such as engines and motors.

[0005] According to the performance testing standards for oil pumps, it is necessary to supply oil at different temperatures to the pump in real time. Temperature is a constantly changing process, and the energy required to supply oil at a specified temperature in real time is considerable. High-temperature testing is relatively simple because the heater is relatively inexpensive to manufacture, and cost control is easier. However, for low-temperature testing, the entire refrigeration system needs to be very large to meet the requirements, resulting in a bulky testing device. Existing testing equipment is bulky, expensive, and has very high operating costs. Utility Model Content

[0006] This invention overcomes the above-mentioned shortcomings. It is compact and small in size, effectively reducing the space occupied. Furthermore, the power configuration of the equipment is low, which greatly reduces the cost of the equipment and significantly reduces energy consumption, achieving true energy saving and environmental protection.

The temperature control system includes an oil tank. The oil outlet of the tank splits into two pipelines, one for low-temperature control and the other for high-temperature control. These pipelines deliver designated oils to the tank via low-temperature and high-temperature oil heat exchangers, respectively, and then return to the tank for mixing. Low-temperature and high-temperature flow meters are installed on each pipeline.

[0014] See Figure 1 This utility model relates to an energy storage type oil pump temperature test bench, which consists of three parts: an energy storage system 1, a temperature regulation system 2, and a working chamber 3.

[0015] The energy storage system 1 is equipped with a low-temperature energy storage tank 4 and a high-temperature energy storage tank 5.

[0016] The cryogenic energy storage tank 4 is used to store low-temperature energy. The cryogenic circulating pump 6 transports the medium in the cryogenic energy storage tank 4 back to the cryogenic energy storage tank 4 through the refrigeration heat exchanger 7 and the cryogenic internal circulation valve 8. The refrigeration heat exchanger 7 is connected to the refrigeration system 9, thereby cooling the circulating medium.

[0017] The high-temperature energy storage tank 5 is equipped with a heater 10 for direct heating, which heats the medium inside the high-temperature energy storage tank 5 to a specified temperature. The high-temperature circulation pump 11 returns the medium inside the high-temperature energy storage tank 5 to the high-temperature internal circulation valve 12. This circulation allows for more complete heat exchange and a more uniform temperature of the medium.

[0018] High-temperature energy storage tank 5 and low-temperature energy storage tank 4 are connected to the replenishment tank 13 above. The replenishment tank 13 is used to replenish the two energy storage tanks and balance the thermal expansion and contraction of the medium in the two tanks.

[0019] The temperature control system 2 includes an oil tank 14, which contains an oil temperature sensor 15. The oil outlet of the oil tank 14 splits into two pipelines, one supplied by a low-temperature regulating pump 16 and the other by a high-temperature regulating pump 17. The oil is then transported back to the oil tank 14 via a low-temperature oil heat exchanger 18 and a high-temperature oil heat exchanger 19 to mix and reach the desired oil temperature. A low-temperature flow meter 20 and a high-temperature flow meter 21 are installed on each pipeline for real-time monitoring and control.

[0020] The cryogenic energy storage tank 4 is equipped with a cryogenic temperature sensor 22. The medium in the cryogenic energy storage tank 4 is connected to the cryogenic circulating pump 6 via the cryogenic outlet valve 23 and the cryogenic oil heat exchanger 18. The high-temperature energy storage tank 5 is equipped with a high-temperature temperature sensor 24. The medium in the high-temperature energy storage tank 5 is connected to the high-temperature circulating pump 11 via the high-temperature outlet valve 25 and the high-temperature oil heat exchanger 19.
