The pulse buffer device is also called a pulsation damper and an air chamber, and is a very effective device for clearing internal flow pulsation. Pressure fluctuations and flow surges in the transfer line can cause piping chatter resulting in damage to the instrumentation, resulting in meter metering misalignment. It uses the compression and expansion of air in the pulse buffer device to store or discharge the fluid whose flow rate is more or less than average flow rate so as to attain the goal of reducing flow pulsation in the conveying pipeline. The pulse buffer device is divided into a normal pressure type and a pre-pressing type according to the pressure of the filled gas. The pre-pressing type pulse buffering device separates gas and liquid by diaphragm and fills gas (air or nitrogen) with certain pressure in advance. The inflation pressure of the pulse buffer device is 0.5-0.8 times of the pressure of the conveying pipeline, and the use effect of the buffer device can be influenced if the inflation pressure exceeds the range. This requires periodic adjustment of the inflation pressure based on the delivery line pressure. And because of the existence of micro leakage, even if the pressure of the conveying pipeline is not changed, the gas needs to be supplemented periodically.
