Detailed Implementation

[0030] The following detailed description, in conjunction with the accompanying drawings, outlines some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0031] Please refer to Figures 1-8 This utility model provides a water pump testing device, including a test platform 1, on which a plurality of water pumps 3 to be tested are arranged. The water pumps 3 to be tested are fixed on a support mechanism 2. The support mechanism 2 is rotatably arranged on the test platform 1. A moving mechanism 5 is arranged between adjacent support mechanisms 2. A water station 4 is arranged at the bottom of the test platform 1.

[0032] The water station 4 is divided into an inlet pool 41 and an outlet pool 42 by a partition 43. A mounting base 11 is fixedly installed on the upper surface of the test bench 1. The water pump 3 under test is fixedly installed on the mounting base 11. The two ends of the water pump 3 under test are respectively connected to an inlet pipe 32 and an outlet pipe 31. Pressure gauges 33 are installed on both the inlet pipe 32 and the outlet pipe 31. One end of the inlet pipe 32 and the outlet pipe 31 are respectively set in the inlet pool 41 and the outlet pool 42.

[0033] This application collects data on water supply network topology, user water consumption, and network ancillary facilities. Using professional modeling software, it constructs a hydraulic model of the network and, based on this model, performs trial calculations and optimizations on the water supply areas of each water plant under the current and planned water supply patterns. This identifies the optimal water supply area and determines the outlet pressure of each water plant's pumping stations. Furthermore, based on the water level of the fourth suction well at each water plant, the pump head and flow rate are determined. This provides a reference for subsequent single-pump selection and multi-pump parallel operation. Using this method for pump selection more closely reflects the actual operating conditions of the water plant, enabling the pumps to operate within their high-efficiency range, thereby achieving energy conservation and consumption reduction.

[0034] Specifically, the water pump 3 to be tested is first fixed by the support mechanism 2, and then the moving mechanism 5 drives the support mechanism 2 to rotate, transferring the water pump 3 to be tested onto the mounting base 11, which reduces the workload and burden of manually placing the water pump.

[0035] The inlet pipe 32 of the water pump under test 3 extends to the bottom of the inlet pool 41, and the outlet pipe 31 is located in the outlet pool 42. A transfer pump is installed inside the outlet pool 42 to transfer the water in the outlet pool 42 to the inlet pool 41 to realize water circulation and ensure the water for water pump testing. The pressure gauge 33 can detect the pressure of the water entering and leaving the water pump under test 3 to help evaluate the performance of the water pump.

[0036] The support mechanism 2 includes a movable frame 21, with casters 22 mounted on the bottom of the movable frame 21. A fixed block 23 is fixedly mounted on the movable frame 21. A first motor 24 is fixedly mounted on one end of the fixed block 23. A bidirectional lead screw 25 is rotatably mounted inside the fixed block 23. Movable blocks 26 are threadedly connected to both ends of the bidirectional lead screw 25. The movable blocks 26 are slidably connected to the inner wall of the fixed block 23. One end of the bidirectional lead screw 25 is fixedly connected to the output end of the first motor 24. A support block 27 is fixedly mounted on one side of the movable block 26. The support block 27 is snapped onto the inlet and outlet of the water pump 3 under test. An installation block 28 is fixedly connected to the end of the fixed block 23 away from the first motor 24. A support column 210 is fixedly mounted on the bottom of the installation block 28. The support column 210 is rotatably mounted on the test bench 1. A gear 29 is fixedly mounted inside the installation block 28.

[0037] Specifically, by starting the first motor 24 to drive the bidirectional lead screw 25 to rotate, the movable blocks 26 on both sides move closer or further apart simultaneously, thereby causing the support block 27 to move synchronously. The position of the support block 27 is adjusted according to the position of the inlet and outlet of the water pump 3 under test. After adjustment, the inlet and outlet of the water pump 3 under test are respectively clamped onto the two support blocks 27. Then, the first motor 24 is used to bring the support blocks 27 on both sides closer together to clamp the water pump 3 under test, thus fixing the water pump 3 under test. One end of the support block 27 is U-shaped, which can prevent the water pump 3 under test from falling and improve the stability of clamping the water pump 3 under test.

[0038] The support column 210 is rotatably mounted on the test bench 1. The support column 210 is concentric with the gear 29. When the gear 29 rotates, the support column 210 and the fixing block 23 rotate around the gear 29. The caster 22 moves along the surface of the test bench 1 to transfer the water pump 3 to be tested to the mounting base 11. Then, the water pump 3 to be tested is fixed to the mounting base 11 by fasteners. The stability of the water pump 3 to be tested during operation is improved by the clamping and fixing of the support block 27 and the reinforcement of the fasteners.

[0039] The moving mechanism 5 includes a fixed frame 51, which is fixedly installed on the test bench 1. Guide rails 52 are fixedly installed on both sides of the upper surface of the fixed frame 51. A slider 56 is slidably connected inside the guide rail 52. A rack 55 is fixedly connected to one side of the slider 56. The rack 55 meshes with a gear 29. Fixed plates 54 are fixedly connected to both ends of the guide rail 52. One-way screws 59 are rotatably installed on the fixed plates 54. A second motor 53 is fixedly installed on one end of the fixed plate 54. The output end of the second motor 53 is fixedly connected to one end of the one-way screw 59. Connecting plates 57 are fixedly connected to the upper surface of one end of the racks 55 on both sides. A movable plate 58 is fixedly connected to the middle of the connecting plate 57. The movable plate 58 is threaded onto the one-way screw 59.

[0040] Specifically, the moving mechanism 5 is set between two adjacent support mechanisms 2 to simultaneously drive the water pumps 3 under test on both sides to move, thereby improving the fixing efficiency of the water pumps 3 under test. During operation, the second motor 53 is started to drive the one-way lead screw 59 to rotate. Through the threaded engagement between the one-way lead screw 59 and the movable plate 58 and the sliding engagement between the sliders 56 at both ends of the connecting plate 57 and the guide rail 52, the movable plate 58 drives the connecting plate 57 and the racks 55 on both sides to move synchronously. Through the meshing of the racks 55 and the gears 29, the gears 29 drive the fixed blocks 23 on both sides to rotate synchronously, thereby moving the water pumps 3 under test on both sides to the mounting base 11 at the same time, achieving efficient installation.

[0041] In summary, the working principle of the water pump testing device according to this utility model embodiment is as follows:

[0042] In use, the first motor 24 is started to drive the bidirectional lead screw 25 to rotate, causing the movable blocks 26 on both sides to move closer or further apart simultaneously, thereby moving the support block 27 synchronously. The position of the support block 27 is adjusted according to the positions of the inlet and outlet of the water pump 3 under test. After adjustment, the inlet and outlet of the water pump 3 under test are respectively secured to the two support blocks 27. Then, the first motor 24 is used to bring the support blocks 27 on both sides closer together, clamping the water pump 3 under test and fixing it in place. The second motor 53 is started to drive the unidirectional lead screw 59 to rotate, thereby moving the support block 27 synchronously. The threaded engagement between the lead screw 59 and the movable plate 58, and the sliding engagement between the sliders 56 at both ends of the connecting plate 57 and the guide rail 52, cause the movable plate 58 to drive the connecting plate 57 and the racks 55 on both sides to move synchronously. Through the meshing of the racks 55 and the gears 29, the gears 29 drive the fixed blocks 23 on both sides to rotate synchronously, thereby moving the water pumps 3 under test on both sides to the mounting base 11 simultaneously. The water pumps 3 under test are fixed to the mounting base 11 by fasteners, achieving efficient installation. During testing, the water pumps 3 under test are turned on, and the water pumps start to run, with water flowing through the inlet pipe 32. The water enters the pump, and the pressure value during the water suction process is recorded by observing the pressure gauge 33 on the inlet pipe 32. This is used to judge the water suction performance of the pump. After being pressurized by the pump, the water is transported to the outlet pool 42 through the outlet pipe 31. The pressure gauge 33 on the outlet pipe 31 is monitored to reflect the pressurization capacity of the pump. It is checked whether the pressure reaches the expected standard and whether it can output continuously and stably. The transfer pump in the outlet pool 42 is started to continuously transport the water in the outlet pool 42 to the inlet pool 41 to ensure the supply of test water. This application collects water supply network topology data and user water... Based on data such as water volume information and pipeline ancillary facilities, a hydraulic model of the pipeline network is constructed using professional modeling software. Based on this model, trial calculations are performed to optimize the water supply areas of each water plant under the current and planned water supply patterns, identifying the optimal water supply zones. This determines the outlet pressure of the pumping stations in each water plant, and then the pump head and flow rate are determined based on the water level of the fourth suction well at each station. This provides a reference for subsequent single-pump selection and parallel operation of multiple pumps. Using this method for pump selection more closely reflects the actual operating conditions of the water plant, enabling the pumps to operate within their high-efficiency range, thereby achieving energy conservation and consumption reduction.

[0043] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
