Description

Technical Field

[0001] The utility model relates to the field of mechanical test equipment, in particular to a fluid mechanics test device. Background Technique

[0002] Fluid mechanics is a branch of mechanics, mainly studying the static state and motion state of fluids under the action of various forces, as well as the interaction and flow laws when there is relative motion between fluids and solid boundaries. In the process of studying fluid mechanics, fluid mechanics devices are often required.

[0003] Referring to a fluid mechanics test equipment disclosed in a Chinese patent with the publication number CN220454832U, which includes a test bench, a water pump installed on the upper surface of the test bench through a base, and a fluid mechanics device body installed on the upper surface of the test bench on the side away from the water pump. A water tank is arranged on the side of the water pump away from the fluid mechanics device body. An adjustment component is further included between the water pump and the fluid mechanics device body. When this technical solution is used, the flow rate of the water flowing into the fluid mechanics device body can be adjusted by the movement of the baffle, so that the fluid mechanics device body can test water flows with different flow rates. For the above technical solution, although it realizes the test of water flows with different flow rates, it cannot perform mechanical tests on water flows under different pressure flow rates during the test, which is inconvenient during the test.

A control valve is fixedly installed on the connecting pipe. One end of the connecting pipe is fixed on the cylinder body.

[0016] Through the above technical solution, the turbine pressurizes the water flow and then enters the interior of the cylinder through the connecting pipe, facilitating the subsequent movement of the water by the piston seat.

[0017] In summary, the present application includes at least one of the following beneficial technical effects:

On the fixed seat 2, a rotary handle 7 is rotatably installed. Inside the water tank 11, a filtering component 23 is fixedly installed. The filtering component 23 is a filter plate, which filters the water discharged from the circulation pipe 10, and then the filtered water is extracted through the suction pipe 13, thus avoiding damage to the equipment caused by impurities in the water.

[0028] See Figure 2 and Figure 3 , on the rotary handle 7, a rotating column 14 is fixed. At one end of the rotating column 14, a ball valve 15 is fixed.
