Instrument technical data Small piston diameter 1.4cm Large piston diameter 4.8cm Small piston area 1.54cm Large piston area 18cmm2 Normal pressure 2-2.2Mpa The pressure of the large piston is about 3.14KN at normal pressure. Demonstration experiment: A crushed vertically and closed the chalk at work. B compression spring. The small piston is slightly energized, and a large force can be obtained on the large piston. C stamped metal sheet. Put a large nut on the workbench, put a thin iron on the nut, put a nail on the iron, shake the handle, and when the pressure reaches a certain value, the iron will deform. D bending steel with a diameter of 4mm or less. Put the round steel in the bending device and shake the handle to reach a certain pressure value, the round steel will bend.

• This machine model is used for middle school physics experiments to illustrate the structure and principle of the machine.
• The instrument is equipped with a small cylinder, a large cylinder and a pressure gauge or an angle cutting valve.
• They are all fixed to the base and then connected to each other by a conduit. The fuel tank is fixed inside the base.
• Size: 270 × 165 × 335mm
• Note: The instrument should be handled gently to prevent it from falling and damage the instrument. It should be stored in the instrument cabinet after the experiment. The stop of the pressure gauge seat should not be overturned to prevent the steel ball inside the seal from falling. In the course of the experiment, after achieving the obvious experimental results, do not continue to force, so as not to damage the instrument sealing parts.
