The principle of pneumatic blasting testing machine

Pneumatic blasting testing machines are widely used in quality inspection units, various vehicle parts manufacturing units, product quality inspection stations, scientific research institutions, and other flexible hose production for burst pressure measurement and pressure resistance time measurement and testing. What is its principle? Below, the editor will give you a brief introduction.

The main core component of the pneumatic blasting test machine is the gas-liquid booster pump, which uses compressed air as a power source to drive the large piston and push the small piston to generate high hydraulic pressure. On the basis of the gas-liquid booster pump as the core component, the configuration includes a blasting box for blasting protection, an electric water injection pump for fast water injection to save test time, a gas source switch for starting and stopping the gas-liquid booster pump, a pressure regulating valve for adjusting the intake pressure to regulate the high-pressure liquid output pressure for stepless pressure regulation, a high-pressure peak pressure gauge for recording the instantaneous pressure of the tested piece during blasting, and a series of accessories such as high-pressure pipelines for stepless pressure regulation, which can be applied to various pressure blasting tests. The principle of the pneumatic blasting test machine is to combine the functions of various accessories mentioned above to achieve the purpose of using the gas source as the power source, adjusting the output pressure by adjusting the gas source function, and recording high pressure with a peak pressure gauge to test the pressure resistance and blasting of the test piece.

Generally, pneumatic blasting testing machines have requirements for on-site conditions. The gas source should be free of impurities and moisture, with a pressure of 2-8 bar (6-8 bar) and a flow rate of about one cubic meter per minute. The medium used is various non corrosive and low viscosity liquids such as pure water or hydraulic oil. The power supply is 220V. The blasting parameters are: blasting pressure range 0-320MPA. The flow rate depends on the model of the booster pump.
