[0027] Specifically, the working principle of the wall-mounted fluid statics experimental device is as follows: when in use, the fixing plate 100 is installed and fixed on the laboratory wall or the fixing frame so that it is suspended in the air, oil is added to the interior of the pressure measuring tube VI 360 from above, the exhaust valve 222 and the stop valve 241 are opened, and water is added to the water level lifting cylinder 120.

By rotating the internal threaded knob 134 to change the height of the water level lifting cylinder 120, the pressure at the measuring point will also change accordingly. This makes it convenient to read data, which is beneficial to reducing experimental errors and improving data accuracy. At the same time, it is easy to change the pressure in the experiment, which can be more flexible and convenient in the experiment.
