[0002] Before being installed and delivered, a water pump needs to undergo a series of tests to determine whether the water pump meets the delivery standard. One of the tests is water pressure test of the water pump. Through the water pressure test, it is determined whether the water pump has defects such as water leakage and sweating. In order to meet the delivery date and delivery requirements, sometimes multiple water pumps need to be tested at the same time. Different pump types and different orders of water pressure tests are different. Therefore, in order to meet these requirements, a water pressure test bench for testing different water pressures of multiple water pumps at the same time must be designed.

[0003] However, the existing water pump water pressure test bench can only test the pressure of one water pump, which is time-consuming and labor-intensive, and the manufacturing material cost is large. The present application provides a water pressure test bench that can test the pressure of multiple water pumps and save manufacturing material cost. The complexity of the test bench is reduced, and the safety of water pressure test of different pump types is met. Content of the utility model

The device is provided with four testing devices, and four pumps can be tested at the same time. Compared with the single-pump water pressure testing device, the testing time is greatly shortened, the compact structure not only meets the appearance requirement, but also saves the manufacturing material cost.

[0007] In a preferred embodiment, the surface of the main pipeline is provided with an electric regulating valve, and the end of the electric regulating valve is fixedly installed with the pump to be tested.

[0008] By adopting the technical scheme, the electric regulating valve can automatically adjust the opening of the valve according to the preset parameters, so as to control the water flow pressure and flow through the valve. This is particularly important in the water pressure test, because it is necessary to maintain a specific pressure level at different stages.

[0009] In a preferred embodiment, the lower surface of the test table body is fixedly installed with a water tank, one side surface of the water tank is fixedly connected with a water tank outlet, and the end of the water tank outlet is fixedly installed with a test pump.

When the system pressure drops, the gas in the pressure stabilizing tank expands, releasing pressure to supplement the system. When the system pressure rises, the gas in the pressure stabilizing tank is compressed, absorbing excess pressure. This mechanism ensures the stability of the pressure during the test, avoiding the influence of pressure fluctuations on the test results.

The device is provided with four testing devices, which can simultaneously test the water pressure of four pumps. Compared with the single pump water pressure testing device, the test time is greatly shortened, and the compact structure not only meets the appearance requirement, but also saves the manufacturing material cost.

[0021] The electric regulating valve can automatically adjust the opening of the valve according to the preset parameters, thereby controlling the water flow pressure and flow through the valve. This is particularly important in water pressure testing, as specific pressure levels need to be maintained at different stages. The outlet of the water tank is connected to the pressure testing pump, and the water flow re-enters the new test water pump through the pressure testing pump and a series of pipelines, thereby achieving the recycling of test water and reducing water resource waste.

The pressure testing pump is in an automatic start-stop state, and its pressure value is maintained at 4.0 MPa. The start and stop of the pump are controlled by the PLC. When a single pump is tested, the appropriate pressure testing flange is selected according to the inlet and outlet diameters, and the "start" button of the semi-automatic control cabinet is pressed. The inlet regulating valve is slowly opened, and the outlet regulating valve is closed by 80%. At this time, the pressure sensor detects that the pressure is rising to 0.1 MPa, and the control cabinet automatically closes the outlet valve. The pressure continues to rise to the required test pressure of 2.2 MPa, and the inlet valve is closed. The device is provided with four testing devices, which can simultaneously test the water pressure of four pumps. Compared with the single-pump water pressure testing device, the testing time is greatly shortened, and the compact structure not only meets the appearance requirement but also saves manufacturing material cost.

[0032] The surface of the main pipeline 17 is provided with an electric regulating valve 12, and the end of the electric regulating valve 12 is fixedly installed with a tested pump 14. The electric regulating valve 12 can automatically adjust the opening of the valve according to the preset parameters, thereby controlling the water flow pressure and flow through the valve. This is particularly important in water pressure testing, as specific pressure levels need to be maintained at different stages.

[0033] The lower surface of the test bench body 1 is fixedly installed with a water tank 9, one side surface of the water tank 9 is fixedly connected with a water tank outlet 10, and the end of the water tank outlet 10 is fixedly installed with a pressure testing pump 11.

[0040] The electric regulating valve 12 can automatically adjust the opening of the valve according to the preset parameters, thereby controlling the water flow pressure and flow rate through the valve.
