step 4, when the safety mechanism 204 is started to work, the equipment is started to work, then the driving mechanism 1024 drives the vibration mechanism 103 to start, and further drives the operating platform 104 to vibrate, and further drives the workpiece to vibrate to simulate a real working environment;

step 5, simultaneously, the liquid in the water tank 101 sequentially passes through the leather hose 1012 and then enters the multi-station air inlet pipe 302, and finally enters the tested workpiece until the liquid is pressurized to a first pressure parameter, then pressure maintaining is carried out, after the set first pressure maintaining time is reached, pressurization is carried out again until a set second pressure maintaining parameter is reached, then second pressure maintaining is carried out until the set pressure maintaining time is reached, an operator watches the change of the pressure reducing value in the display screen of the electric control mechanism 211, when the pressure reducing value is exceeded, the equipment gives an alarm, and the state of the display screen corresponding to the tested workpiece is displayed in red to be unqualified;

step 7, after blasting is finished, stopping vibrating the vibration mechanism 103, driving the workpiece on the surface of the operating platform 104 to stop vibrating, starting the blowing nozzle 306 to blow off redundant liquid on the workpiece to be detected, and then lifting the detection door 2034;

and 8, when the detection door 2034 is lifted to the top of the detection bin 2, the operator takes out the workpiece, and the experiment is finished.

The preferred embodiments of the present invention have been described in detail with reference to the accompanying drawings, however, the present invention is not limited to the specific details of the embodiments, and various equivalent changes can be made to the technical solution of the present invention within the technical idea of the present invention, and these equivalent changes are within the protection scope of the present invention.
