The drawing shows a principle-15 diagram of a test bench for pneumatic equipment.

The bench contains a power source 1, communicated with the working cavity (Not marked) of the test power cylinder 2 by means of the test control unit 3: and with control block 4, an imitation device for loading the power pneumatic cylinder 20

Minimum 18-20 to the corresponding inputs (not indicated) of the load cylinder 7 and blocks 3, 4 of the control and control, respectively. In this case, the loading pneumatic cylinder 7 acts on the loading platform 8 with interchangeable weights 9, lifting it and thereby ensuring interaction with the test control unit 4. After stopping the supply of compressed air to the load pneumatic cylinder 7 and depressurizing it through the elements of the pneumatic panel 21, the loading platform 8 descends and loads the control unit 4.

By changing the number of replaceable loads 9, the operation with a load of any weight is simulated, and the test control unit 4, when loaded from the loading platform 8, processes the signal from the force of the load, as well as the control signal for lifting or lowering the load 6 from the operator's effort and
