Description

Technical Field

[0001] This invention belongs to the technical field of pump test platforms and design methods, and particularly relates to an integrated test platform for water pumps and oil pumps and its test method. Background Technology

[0002] Water pumps and oil pumps are the most common rotating mechanical equipment in industrial production. Their performance directly affects the efficiency and reliability of the entire adapted system. Due to the different transmission media (water and oil), water pumps and oil pumps often participate in the system work as independent functional units. However, in many complex sets of equipment, water pumps and oil pumps need to work together to achieve their functional effects. For example, in marine diesel engines, oil pumps provide fuel and lubrication, while water pumps draw seawater to cool the engine and lubricating oil. In oil refining units in the petrochemical industry, oil pumps transport raw materials and products, while water pumps operate in cooling towers and heat exchanger systems to cool the entire transmission system. On industrial production lines, a large press uses a hydraulic pump to provide pressure, while its hydraulic station may require a separate cooling water pump to cool the hydraulic oil. The above examples show that when a system simultaneously has the needs for "cooling, cleaning, and circulation" using water as a medium and "power, lubrication, and fuel" using oil as a medium, the coordinated operation of water pumps and oil pumps is necessary to ensure the safe and efficient operation of the complex system. Therefore, after the design and manufacturing of water pumps and oil pumps are completed, their performance parameters need to be collected and evaluated. Using bench tests to simulate actual working conditions and analyzing system data is the most intuitive and reliable verification method.

[0003] Chinese patent CN111442919A (application date: July 24, 2020) reports a lubricating oil pump test bench. Addressing the problems of low efficiency caused by the need for multiple test locations and repeated pump movements in existing technologies for testing multiple lubricating oil pumps, this design presents a main oil tank with multiple inlet and outlet pipelines, connected to the power transmission system, vacuum system, cooling system, electrical control system, and lubricating oil pumps respectively, enabling multi-loop measurement. This design provides a multi-port parallel multi-pump synchronous online testing scheme with advantages such as complete overall functionality, high system integration, convenient disassembly and assembly, and reasonable layout. By adjusting system parameters, the performance of the lubricating oil pump under different operating conditions can be tested. However, this method only achieves systematic testing for a single oil pump and cannot meet the integrated testing requirements under dual-medium operating conditions.

[0004] Chinese Patent CN119594030A (application date: December 4, 2024) discloses a visualized integrated test bench and experimental method for a single-stage gas-liquid mixed-transfer pump used for optimization verification. A motor is fixedly mounted on the test bench body. The motor's output shaft is sequentially connected to a torque meter, a rotating shaft, and the pump shaft of the single-stage gas-liquid mixed-transfer pump. A bearing is mounted on the rotating shaft. A bearing housing is fixed on the test bench body at the position corresponding to the bearing. A left metal baffle is detachably fixed to the side of the bearing housing closest to the single-stage gas-liquid mixed-transfer pump. A right metal baffle is detachably connected to the side of the left metal baffle away from the bearing housing via a screw. The single-stage gas-liquid mixed-transfer pump is positioned between the left and right metal baffles. A guide vane and an impeller are detachably connected to the other end of the pump shaft sequentially from the left to the right metal baffle. The test bench effectively simulates the real-world operating environment of a dual-medium mixed-transfer pump, achieving integrated measurement of the dual-medium pump. It has a high degree of system integration and solves the problem in existing technologies where test benches cannot perform repeated tests, leading to cumbersome experimental processes. However, this method is only designed as an effective measurement method for dual-medium mixed pumps and is not applicable to the synchronous measurement of water pumps and oil pump systems that work together.

[0005] Yu Xianhua et al. proposed a design and testing method for a nuclear power high-temperature and high-pressure pump test bench (Yu Xianhua, Wang Yanrui, Zhong Zuowen, et al. Research on high-temperature and high-pressure pump test bench [J]. Pump Technology, 2009, (05): 24-26.). The test system is equipped with a main pump test loop, a pressure supply system, a heating system, a cooling system, a circulation system, and a water storage tank. The required temperature and system pressure are achieved by adopting resistance wire heating pipes, a main pump heating system, and insulation measures. The specific operation is as follows: First, open the electric gate valve of the circulation system suction pipe to start the shielded electric centrifugal pump of the circulation system. After the electric centrifugal pump starts, open the electric gate valve of the circulation system discharge pipe, and debug the circulation system. When the circulation system is running normally, stop the main pump and close the regulating valve set after the flow meter in the main loop. At this time, the circulation system of the auxiliary loop and the main loop form a closed circulation system. The equipment cooling water of the main pump is supplied normally. After the temperature is constant, open the valve and start the operation at the system pressure and system temperature. Adjust the valves after the flow meter to record the following parameters at each measurement point: flow rate, head, input power, voltage, current, grid frequency, stator winding temperature, cooling water inlet and outlet temperatures, and flow rate. Check the test results, plot the QH, QP, and Q-η curves, and check the unit's noise and vibration. This pump testing temperature control system can simulate actual temperature conditions, and the measurement results are more realistic. However, the operation is relatively cumbersome, and it only reproduces the complex operating conditions of a single pump, lacking test analysis of the coordinated operation of oil pumps.

[0006] Chinese patent CN111442919A (application date: July 24, 2020) reports a lubricating oil pump test bench. Addressing the inefficiencies caused by the need for multiple test locations and repeated pump movements in existing lubricating oil pump tests, this design incorporates a main oil tank with multiple inlet and outlet pipelines, connected to the power transmission system, vacuum system, cooling system, electrical control system, and lubricating oil pump, enabling multi-loop measurements. This design provides a multi-port parallel multi-pump synchronous online testing scheme with advantages such as complete overall functionality, high system integration, convenient assembly and disassembly, and reasonable layout. By adjusting system parameters, the performance of the lubricating oil pump under different operating conditions can be tested. However, the shared medium only allows for testing of a single oil pump and cannot meet the requirements for integrated testing of water pumps and oil pumps.

[0007] Chinese patent CN221462504U (application date: November 6, 2023) discloses a comprehensive test bench for vehicle oil pumps and water pumps. The test bench includes a test bench body, a multi-media assembly, and detection and cleaning components disposed between the test bench body and the multi-media assembly. A distributor connects the oil pump and water pump to a graded storage tank, allowing switching between the oil pump and water pump for different media, achieving an integrated design. This test bench tests either the water pump or the oil pump through pipeline switching and system integration control. Ultrasonic cleaning purifies the pipelines, achieving a shared pipeline effect. This method effectively saves on pipeline layout and significantly reduces the overall space occupancy of the equipment. However, in practical applications, this device cannot simultaneously acquire data from both pumps, thus failing to improve testing efficiency.

[0008] The aforementioned measuring devices and methods can test water pumps or oil pumps in a single loop, offering advantages such as convenient operation and high integration. The system design considers the impact of temperature rise on test results and incorporates a cooling system within the loop, resulting in more comprehensive overall functionality. However, analysis reveals shortcomings: the testing process fails to effectively simulate the working conditions of water pumps and oil pumps working in tandem. Furthermore, the testing of water pumps and oil pumps is typically conducted separately, requiring independent cooling systems and piping, leading to excessive space occupancy, high equipment costs, and low testing efficiency. Summary of the Invention

[0009] The purpose of this invention is to provide an integrated testing platform and testing method for water pumps and oil pumps, which solves the problems of insufficient reproduction of water pump and oil pump coordinated working conditions, excessive space occupation, and low efficiency of existing test benches.
