After that, the impurity simulation medium in the water will be The water is intercepted by the filter 253 and guided into the impurity storage tank 232. The water will pass through the filter 253 and the liquid pump tube 233 into the telescopic hose 261, and then flow into the supply tank 262 through the telescopic hose 261 to form a cycle. At this time, the impurity simulation medium in the water is filtered by the filter 253, so the pure water flow test of the turbine body 1 can be performed. When it is necessary to change the water pressure environment simulation of the test mechanism 3, the adjustment winch 213 can drive the adjustment frame 263 to rise and fall along the adjustment guide rod 212, thereby changing the distance between the positioning frame 221 and the adjustment frame 263, thereby adjusting the length of the test mechanism 3 to change its environmental simulation of the water pressure.

The telescopic sleeve 322 can slide at the downpipe 321 and the positioning pipe 323, so as to adapt to the orientation adjustment of the downpipe 321 and the positioning pipe 323, and always provide the water transported by the downpipe 321 to the positioning pipe 323.

[0057] The working principle of this embodiment is as follows: first, the test mechanism 3 is connected to the PLC and powered on and started. Then, when the circulation mechanism 2 is displaced, the downpipe 321 will drive the telescopic sleeve 322 to rise and fall, so as to change the distance between the downpipe 321 and the positioning tube 323, and change the water capacity of the downpipe 321, the telescopic sleeve 322 and the positioning tube 323, so as to adjust the water pressure in the turbine body 1. After passing through the turbine body 1, the water flow will pass through the flow measuring tube 311 and the ultrasonic flowmeter 312. The ultrasonic flowmeter 312 will control the water flow rate through the control of the PLC, and display the detection results of the ultrasonic flowmeter 312 to the user who is observing through its own image display device. Finally, the water flow will be diffused through the diffusion diversion pipe 313 and sent back to the circulation mechanism 2.
