Method for confirming the volume of the air storage tank
Thread Content
Dear seniors and teachers: The requirement is that pneumatic valves must be equipped with pneumatic actuators that include air storage tanks. I need to determine what the minimum volume of the air tank is required so that the pneumatic system can operate once, relying solely on the compressed air stored in the tank, in the event of a power or gas outage in the external network It is known that the air consumption per cylinder cycle is 59 L, and the minimum air supply pressure is 0.4 Mpa. How to calculate it? Thank you first!
Some kind of equation that can be used to estimate it. PV=nRT; since nR is not very convenient to use, we consider the relationship between pressure P, volume V, and temperature T.

According to (SH3020-2001), the gas consumption of ordinary instruments is based on stable data under operating conditions (140 KPa, 20°C); using the formulas specified in the standards to convert these values to standard conditions (101.33 KPa, 20°C), the consumption is approximately 91 L. Assuming that the normal operating pressure of the gas supply is 0.7 Mpa and the minimum output pressure is 0.4 Mpa, the volume of the gas storage tank is approximately 30 L, as calculated using the gas law PV=nZRT.
