When performing SY/T 6817-2010 Calibration method of anti-vibration pressure gauge to calibrate anti-vibration pressure gauges,it is necessary to apply sine wave pulsation pressure at a test point between 30% and 40% of the measuring range,its amplitude is not more than 10% of the pressure value at this point,and the pulsation frequency is (60±5) times per minute.In order to obtain such a pulsating pressure source,the reference value of the inspection point was generated by the pre-pressure of the air- driven liquid pump,and the high-pressure value with a 10% increase was generated by using the liquid-driven liquid booster cylinder,and then the reciprocating motion of the booster cylinder piston controlled by the servo hydraulic pressure produced sinusoidal pulsations with fluctuation range between the reference value and the high pressure value.The developed calibration device is convenient to set pulsation frequency and amplitude,and the influence of environmental parameters is little.It is controlled by the acquisition card of the industrial computer,with a clear display interface and high control accuracy,which is suitable for calibration anti-vibration pressure gauge in test room and verification room.
