The maintenance content of the pressure vessel in the air compressor system during the outage period is as follows: 1.Keep the pressure vessel dry and clean to prevent atmospheric corrosion. Scientific practice has proved that dry air generally does not corrode carbon steel and other ferroalloys. Corrosion starts only when there are dust, dirt or old corrosion products on the metal surface when we...

There are many reasons for the abnormal shutdown of the air compressor. Excessive temperature is an important reason. Excessive temperature will cause some parts of the air compressor to fail to operate normally, resulting in shutdown. Reason analysis of high temperature of screw air compressor: ① Insufficient amount of lubricating oil, incorrect specifications of lubricating oil, different viscos...

The working principle of PSA oxygen generator： The normal air composition is: nitrogen (N2) accounts for about 78.1%, oxygen (O2) accounts for about 20.9%, and rare gases account for about 0.939% (helium He, neon Ne, argon Ar, krypton Kr, xenon Xe, radon Rn), Carbon dioxide (CO2) accounts for about 0.031%, and other gases and impurities account for about 0.03% PSA (Pressure Swing Absorption) oxyge...

The screw compressor cylinder is equipped with a pair of intermeshing spiral female and male rotors. Both rotors have several concave teeth, and the two rotate in opposite directions. The main rotor (also called a male rotor or a convex rotor) is driven by an engine or an electric motor (mostly driven by an electric motor), and the other rotor (also called a female rotor or a female rotor) is driv...

1. Selection of working pressure (exhaust pressure): When the user is preparing to purchase an air compressor, first determine the working pressure required by the air end, plus 1-2 The margin of bar, and then select the pressure of the air compressor, (the margin is to consider the pressure loss from the installation location of the air compressor to the actual gas end pipeline distance, and the ...

Air contains 21% oxygen, 78% nitrogen, 0.9% argon and 0.1% other trace gases. PSA oxygen generator uses zeolite molecular sieve as adsorbent. Use two containers with zeolite molecular sieves (two towers, four towers or six towers) as adsorbents, using the principle of pressure adsorption and decompression desorption to adsorb and release oxygen from the air, thereby separating the oxygen from the ...
