gas storage tank is commonly used in industry An industrial equipment for purifying and compressing air is also one of the special safety equipments strictly regulated by the state. It also directly affects the unloading of air compressors, so it plays a vital role in the correct selection of gas storage tanks: /span> First of all, we should select the products produced by the company with the corresponding special equipment production qualification and strictly implement the GB/T150-2011 "Pressure Vessel" standard. Secondly, many customers choose inverter air compressors due to fluctuations in gas consumption. In fact, a large part of them can directly use relatively large gas storage. Tanks reduce the unloading time of the air compressor, which saves a lot of energy. The gas tank can be selected according to the following formula: V=N×Q÷(P+1) V: Gas tank volume Q: Air compressor displacement P: exhaust pressure N is a parameter. The recommended value for customers with stable gas consumption is 1~2. The recommended value is fluctuating frequently but the fluctuation value is not large. 3. If the fluctuation is frequent and the fluctuation value is large, it is recommended to take the value above 4.
1. When the air compressor or the external pipe network suddenly stops supplying air, if the pneumatic equipment needs to work for a certain period of time, the calculation formula of the gas tank volume is : V≥PaQmaxT/60(P1-P2) (L) 2. If the suction flow of the air compressor is selected according to the average air consumption of the pneumatic system, when the pneumatic system is working at the maximum air consumption , then The formula for the volume of the gas tank is: V1= (Qmax-Qsa) Pa /P*(T'/60) (L) (1) V=P*V1 /(P1-P2) (2) From (1), (2): V=(Qmax-Qsa)Pa*T/(60(P3-P2)) where: P1: the pressure at which the air supply is stopped, MPa P2: Minimum working pressure allowed for pneumatic systems, MPa P3: maximum working pressure of the gas tank, MPa Pa: atmospheric pressure, Pa=0.1MPa Qmax: Maximum air consumption of the pneumatic system, L/min (standard state) T: The time during which the pneumatic system should be maintained after the gas supply is stopped, s Qsa: Average air consumption of pneumatic systems, L/min (standard state) P: pressure of pneumatic system, MPa (absolute pressure), Pa=0.1MPa T’: working time of the pneumatic system at maximum air consumption, s V1: Effective gas storage volume of the gas tank
