1. What is the pressure and flow rate of the air compressor?

Taiwan DPC answers for you: Compressed air flow calculation formula: L=AvL: Flow rate A: Pipeline compressed air outlet area v: The average flow rate of compressed air in the pipeline. Compressed air is discharged from a pipeline with a diameter of 16mm and a pressure of 0.9mpa. How to calculate the flow rate of compressed air returning to Gaozheng in this pipeline? Assuming that (1) flow resistance loss is not taken into account, (2) when compressed air leaks to the pipe mouth, all pressure energy is converted into kinetic energy. Solution: P=0.5 ρ V2 ρ --- density 1.19 V2--- velocity squared P -- static pressure (acting on the surface of the object) v=sqrt (2 * 900/1.19)=38.89m/s. The outer diameter of the steel pipe is D=16mm, and the inner diameter is calculated as d=12mm. L=Av=(π/4) × 0.012 × 0.012 × 38.89=0.0044 cubic meters/second=15.834 cubic meters/hour

2. Flow calculation of the air compressor

Flow calculation of the air compressor? The definition of standard state is an air state with a pressure of 0.1 MPa, a temperature of 20 ℃, and a relative humidity of 65%. In standard conditions, the density of air is ρ=1.185 Κ g/m3. According to the international standard ISO8778, the unit in standard conditions can be marked with "(ANR)". If the air flow rate under the standard state of burning paulownia is 6M3/min, it can be written as 6M3/min (ANR). The state of dry air with a temperature of 0 ℃ and a pressure of 101.3KPa, and a density of ρ=1.293 Κ g/m3 in the reference state. The difference between standard state air and reference state air lies in temperature and moisture content. When there is moisture in the air, once the moistu

re is separated, the amount of air will decrease. Air in the inlet state of the compressor. Measured vertically above sea level, altitude simply refers to the height above sea level. Altitude plays an important role in compressor engineering, as the higher the altitude, the thinner the air and the lower the absolute pressure. Since the air at altitude is relatively thin, the cooling effect of the motor is relatively poor, which limits the operation of standard motors to a certain altitude. Volumetric flow rate refers to the flow rate of air drawn in by the compressor at the reference state during a single skin level time. Expressed in m3/min (cubic meters per minute). To distinguish from the flow rate under standard conditions, NM3/min is used. 1CFM=0.02832m3/min, 1m3/min =35.311CFM, Load factor refers to the ratio of the average output of a compressor to its maximum rated output during a certain period of time. The unwise approach is to sell compressors to users that precisely meet their maximum needs. Adding one or a few tools or having leaks can lead to a decrease in pressure in the factory. To avoid this situation, it is recommended to use a load factor: take the maximum amount of gas required by the users system and divide it by a load factor of 0.9 or 0.8. This comprehensive air volume selection (or any user considers it a safety factor) can take into account unexpected increases in air demand. Small scale expansions can be made without the need for additional capital investment.

(1) The displacement of the screw compressor is V=ф× D3 × λ× nV, and the actual displacement is V=V × η

(2) Influencing factors: pj, Tj, altitude, n, V surplus, leakage, etc.
