Technical Field

[0001] This utility model relates to the technical field of testing fixtures, and in particular to a testing fixture for water circulation of a solar deep well pump motor. Background Technology

[0002] With the rapid development and widespread application of solar energy technology, solar deep well pumps, as a high-efficiency and environmentally friendly water intake device, have received widespread attention and application in fields such as agricultural irrigation, domestic water supply, and industrial water use. The performance stability and reliability of the solar deep well pump motor are crucial to its overall working effect. In order to ensure the good performance of the solar deep well pump motor in practical applications, rigorous testing is an essential step.

[0003] Currently, among existing testing equipment, such as the patent with authorization announcement number CN206132944U, this utility model provides a water circulation testing fixture for deep well pump motors, belonging to the field of mechanical technology. It solves the problems of complex operation and high environmental requirements in existing water pump motor testing. This deep well pump motor water circulation testing fixture includes an eddy current dynamometer connected to the shaft of the motor under test and a simulated water circulation system for mounting the motor under test. The simulated water circulation system includes a barrel with an internal receiving cavity, an inlet and an outlet on the barrel respectively communicating with the receiving cavity, and an installation port on the barrel communicating with the receiving cavity. The motor under test is installed into the receiving cavity through the installation port.

[0004] However, it was found during the use of the equipment that it was not convenient to test the motor and water pump under different water pressures, which increased the limitations of the test and reduced the convenience of the test. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides a solar-powered deep well pump motor water circulation test fixture that facilitates simulating water pressure environments at different depths, improves the convenience of testing deep well pump motors to circulate and transport water under different water pressures, reduces testing limitations, and enhances the ease of operation for personnel.

[0006] This utility model discloses a water circulation testing fixture for a solar-powered deep well pump motor, comprising a base and a test chamber. The test chamber is mounted on the top of the base and has an opening at the top. It also includes a conveying device, a pressurizing device, a sealing cover, first cylinders, and a support. The sealing cover is rotatably mounted on the outer wall of the test chamber. The fixed ends of multiple sets of first cylinders are mounted on the inner wall of the test chamber, and the moving ends of multiple sets of first cylinders are connected to the bottom of the support. The base is equipped with a conveying device for conveying clean water into the test chamber. The pressurizing device is mounted on the base for pressurizing the test chamber. The deep well pump to be tested is mounted on the top of the support, and then the pump is fed through multiple sets of first cylinders... The first cylinder drives the support to move downwards, causing the support to move the deep well pump into the test chamber. Then, clean water is delivered into the test chamber through a conveying device, immersing the deep well pump. The deep well pump is then started to circulate the water in the test chamber, thereby testing its motor. By sealing the top opening of the test chamber with a sealing cover, and then pressurizing the test chamber through a pressurization device, the test chamber simulates water pressure environments at different depths. This improves the convenience of testing the deep well pump motor's water circulation under different water pressures and reduces the limitations of the test. By controlling the lifting and moving of the support, the convenience of personnel loading and unloading the deep well pump on the support is improved.

By starting the water pump, water is drawn from the storage tank and conveyed to the test tank through the second conveying pipe. This facilitates simulating the underwater working environment of the deep well pump in the test tank. After the deep well pump motor test is completed, the first valve is opened, allowing the water in the test tank to flow back to the storage tank through the first conveying pipe. Due to the pressure inside the test tank, the pressure accelerates the water flow back through the first conveying pipe, improving the clean water recovery efficiency in the test tank.

The pressurization pump is installed on the outer wall of the base, the output end of the pressurization pump is connected to the third delivery pipe, the output end of the third delivery pipe is connected to the test chamber, and the third valve is connected to the third delivery pipe. By turning on the pressurization pump, the pressurization pump pressurizes the test chamber through the third delivery pipe.

[0009] Preferably, it also includes two sets of second cylinders, the fixed ends of which are rotatably mounted on the outer wall of the test chamber, and the moving ends of which are rotatably connected to the outer wall of the sealing cover respectively; by controlling the extension and retraction length of the moving ends of the two sets of second cylinders, the two sets of second cylinders drive the sealing cover to flip, thereby improving the convenience of controlling the opening and closing of the top opening of the test chamber by the sealing cover.

[0010] Preferably, it also includes a safety valve, which is connected to the sealing cover; by setting the safety valve, the safety of automatic pressure relief inside the test chamber is improved.

Then, multiple sets of first cylinders drive the support to move downwards, so that the support moves the deep well pump into the test chamber. Then, clean water is transported into the test chamber through the conveying device, so that the clean water submerges the deep well pump. Then, the deep well pump is started to circulate the water in the test chamber, thereby testing its motor. By sealing the top opening of the test chamber with the sealing cover, and then pressurizing the test chamber through the pressurization device, the test chamber simulates the water pressure environment at different depths, improving the convenience of testing the deep well pump motor to circulate water under different water pressures, reducing the limitations of the test, and improving the convenience of personnel to load and unload the deep well pump on the support by controlling the lifting and moving of the support.
