Analysis of the relationship between pressure and displacement of airless laboratory air compressor The standard state is defined as: air pressure of 0.1 MPa, temperature of 20 ° C, relative humidity of 65%. In the standard state, the density of air Ï=1.185Κg/m3. The high and low temperature test chamber is in accordance with the international standard ISO8778, and the unit under the standard state can be marked with "(ANR)". If the air flow rate in the standard state is 6M3/min, it can be written as 6M3/min (ANR).
The state of dry air at a temperature of 0 ° C and a pressure of 101.3 KPa, and the density Ï = 1.293 Κ g / m 3 in the reference state. The reference state air differs from the standard state air in temperature and moisture. When there is moisture in the air, once the water is separated, the amount of gas will be reduced.
Air in the state of the compressor inlet.
Measured vertically upwards in sea level, elevation is simply the height above sea level. Altitude plays an important role in compressor engineering because the higher the altitude, the thinner the air becomes and the lower the absolute pressure becomes. Since the air at the altitude is relatively thin, the cooling effect of the motor is relatively poor, which makes the standard motor only confined to a certain altitude. The volumetric flow rate is the air in the compressor suction reference state per unit time. Traffic.
It is expressed in units of m3/min (m3/min). In order to distinguish the flow rate in the standard state, it is represented by NM3/min.

Ruian City Aite Electromechanical "target=_blank> Electromechanical Tip: The load factor refers to the ratio of the average output of the compressor to the maximum rated output of the compressor for a certain period of time. It is unwise to sell the compressor to the user, just to meet The maximum demand of the user, the addition of one or several tools or leaks will cause the pressure of the plant to drop. To avoid this situation, it is recommended to use the load factor: take the maximum value of the gas required by the user system and divide by 0.9 or 0.8. Load factor disperser (or any user considered a safety factor)
Calculation formula:
p=ÏRT
p is the absolute pressure of the gas (Pa), T is the temperature of the gas (K), and R is the gas constant (dry air is R = 287J / (Kg * K))
Ï is the density of the gas (kg / electronic balance m ^ 3)
For wet air, the R of wet air should be used in the calculation.
Air compressor displacement calculation:
Unit displacement = (air density x pressure x tank size) / time-consuming factors affecting the calculation of the above formula are: air temperature, altitude, air humidity, pressure, etc.

The POLYKEN® Polypropylene Coating System is designed for the corrosion protection of new and existing pipelines. The coating layer consists of a tough, woven polypropylene backing with a high tack Butyl Rubber / Bitumen adhesive. An additional layer of POLYKEN® 980 or 955 should also consider to be used on pipes larger than 12" diameter to improve the soil stress resistance of the system.
