A water pump controller test bench

Abstract

This utility model relates to the technical field of water pump controller test benches, and discloses a water pump controller test bench including an outlet tank. A support plate is fixedly connected to one side of the outlet tank, and an inlet tank is fixedly connected to one side of the support plate. A water pipe connects the outlet tank and the inlet tank. A U-shaped component is fixedly connected to the top of the support plate. By setting a servo motor and two meshing gear rotating shafts on the support plate, a pair of rotating blocks and the U-shaped connector are driven to achieve smooth and synchronous lifting of the support platform and the test water pump. This not only allows for rapid and stepless changes in the position between the inlet pipe and the water surface, accurately simulating the entire process of the water pump from normal pumping to dry running, but also enables real-time regulation of the outlet water pressure using an outlet regulating valve, realizing response testing of the controller under different operating conditions. At the same time, the combination of rubber plate vibration isolation and connecting plate mounting holes significantly reduces the impact of operating noise and vibration on the test results.

Technical Field

[0001] This utility model relates to the technical field of water pump controller test benches, specifically a water pump controller test bench. Background Technology

[0002] The reliability of pump controllers is crucial in various water supply, industrial, and building systems. As a core component connecting the control system and pump operation, its main functions include pump start-up and shutdown control, operating status monitoring, pressure or flow regulation, overload protection, and fault alarms. The stability and response accuracy of the controller directly affect the operating efficiency, safety, and service life of the pump system.

[0003] Existing pump controller testing equipment generally suffers from limited testing conditions and inflexible adjustment methods. In particular, when simulating the transition from normal pumping to idling during pump operation, the lack of stable and controllable structural support and precise dynamic adjustment means makes it impossible to comprehensively test the controller's response performance and protection effect under different pressure and water level conditions, thus affecting the reliability assessment results of the controller.

[0004] Therefore, it is necessary to design a water pump controller test bench to solve the above problems. Utility Model Content

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0019] Obviously, many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0020] Please see Figure 1-3This utility model provides a water pump controller test bench, including an outlet tank 2. The outlet tank 2 is characterized by: a support plate 10 fixedly connected to one side; an inlet tank 9 fixedly connected to one side of the support plate 10; a water pipe 22 connecting the outlet tank 2 and the inlet tank 9; a U-shaped component 12 fixedly connected to the top of the support plate 10; a servo motor 11 fixedly connected to one side of the U-shaped component 12; a rotating shaft 14 fixedly connected to the output shaft of the servo motor 11; and another rotating shaft 14 rotatably connected to the inner cavity of the U-shaped component 12. Shaft 14, gears 15 are fixedly sleeved on the outer surfaces of both rotating shafts 14, the two gears 15 mesh with each other, and rotating blocks 16 are fixedly sleeved on both rotating shafts 14. A support platform 19 is slidably sleeved on the top of the two rotating blocks 16, and a test water pump 6 is fixedly connected to the top of the support platform 19.

The support platform 19 is movably connected to the inside of the outlet tank 2 and the inlet tank 9. A controller mounting plate 23 is fixed to the top of the support platform 19, through which a water pump controller is installed, thus connecting the controller to the test water pump 6. By activating the servo motor 11 and engaging two gears 15, the rotation of two rotating blocks 16 causes the support platform 19 to rise and fall, thereby synchronously raising and lowering the impurity removal cover 4 and the inlet pipe 7 on the test water pump 6. When the inlet pipe 7 rises above the water level inside the inlet tank 9... When the test pump 6 is running dry, the controller can adjust its pumping operation before the inlet pipe 7 is raised. After the inlet pipe 7 is raised, the controller can promptly shut off the pumping operation of the test pump 6 while it is running dry. At the same time, the controller can adjust the outlet pressure of the test pump 6 by adjusting the outlet regulating valve 5 and the water flow through the impurity removal cover plate 4. This allows the controller to adjust the pump's operation at different pressures at the outlet of the test pump 6.

[0023] Furthermore, in order to improve the stability of the test water pump 6 driven by the support platform 19, a U-shaped connector 17 is rotatably sleeved on the top of each of the two rotating blocks 16. Two symmetrical T-shaped grooves are opened at the bottom of the support platform 19, and a T-shaped block 18 is fixedly connected to the top of each of the two U-shaped connectors 17. The two T-shaped blocks 18 are respectively slidably engaged in the interior of the two T-shaped grooves.

[0024] Furthermore, in order to facilitate the recycling of the water source for the pump and thus facilitate testing, the two ends of the water pipe 22 are respectively connected to the interior of the outlet tank 2 and the inlet tank 9, and the height of the water pipe 22 at the end of the inlet tank 9 is higher than the height of the end of the water pipe 22 inside the outlet tank 2, and the bottom height of the outlet pipe 4 is lower than the bottom height of the inlet pipe 7.

[0025] To facilitate the adjustment of the circulating water volume inside the outlet tank 2 and the inlet tank 9, the water pipe 22 is located at the bottom of the support plate 10, the top of the inlet tank 9 is connected to the connecting water pipe 8, and the top of the connecting water pipe 8 is equipped with a piston block 21. The filter plate 20 is located at the bottom of one side of the impurity removal cover plate 3, and the bottom end of the outlet pipe 4 is higher than the top of the filter plate 20.

[0026] The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the specific details of the above embodiments. Within the scope of the technical concept of the present invention, various simple modifications can be made to the technical solution of the present invention, and these simple modifications all fall within the protection scope of the present invention.

[0027] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable way without contradiction. In order to avoid unnecessary repetition, this utility model will not describe the various possible combinations separately.
