Description

Technical Field

[0001] This utility model belongs to the field of oil pump testing technology, specifically an oil pump durability testing device. Background Technology

[0002] Oil pumps require long-term stable operation in practical use. Durability testing simulates the long-term operation of oil pumps under various working conditions, testing their ability to continuously and stably deliver oil, and evaluating the reliability of their mechanical structure, seals, bearings, and other components. This ensures that no failures occur within the specified service life. During durability testing, various performance indicators of the oil pump, such as flow rate, pressure, and efficiency, are monitored to observe whether these performance indicators remain within the specified range after long-term operation. This verifies the stability of the oil pump's performance during long-term use, preventing performance degradation from affecting the normal operation of the entire system. Long-term testing can also expose potential problems that are not easily detected in short-term operation, such as component wear, fatigue crack formation, and aging and leakage of seals. Early detection of these problems allows for corresponding improvement measures to be taken, optimizing the design and manufacturing process of the oil pump and improving product quality.

[0003] After completing a test on an oil pump, the testing device requires a series of operations, such as replacing the tested oil pump and adjusting test parameters. During these operations, the testing device is idle and cannot perform effective testing, reducing testing efficiency and affecting subsequent work. Furthermore, the testing device cannot perform multiple modules simultaneously, requiring separate operations, which makes the testing process cumbersome. Operators need to switch between different modules, increasing time and labor costs and reducing the integration and overall efficiency of the test. Therefore, this application proposes an oil pump durability testing device. Utility Model Content
