Air compressor process:

Air circuit: The main motor is energized, and the screw is driven to rotate through the coupling or speed-increasing gear. When it is just started, the intake valve has not been opened. At this time, the air compressor starts at light load again:

The intake valve opens, and the air passes through the air filter element (3 microns) 0.3 mm One intake valve (butterfly valve) → compression chamber → (intake, compression, transmission, discharge) one exhaust to the oil and gas separation cylinder → minimum pressure valve (pressure maintenance The opening value of the valve is 4-4.5 kg (2 functions: ensuring the circulation of lubricating oil, adjusting the opening of the intake valve, non-reverse function, the smallest pressure valve is not the safest non-return valve) a plate-fin cooler

4: 6-head male rotor 4, female rotor 6

5: 6 heads, one big and one small. The rigidity of the two is different, the male diameter is large, the female diameter is small, the male is a forging, and the female is a casting.

Oil circuit: air compressor start, light load start, (inlet valve does not open) (in order to reduce the starting load, establish negative pressure, and pump up the oil from the bottom of the tank for 3-6 seconds,) at the same time star-delta conversion time For 3-6 seconds. The oil is divided into two ways, one way to lubricate the bearing, and two ways to enter the compression chamber, and under the pressure of the compression chamber, the oil will be like objects (for cooling, sealing, lubrication, cooling, and noise reduction). The oil and gas mixture is discharged from the main engine into the oil and gas separation cylinder, (tangential air intake) tangential vortex is generated, the cyclone is separated, hits the baffle plate, and most of the oil is filtered out, and the remaining oil sinks to the bottom of the oil and gas separator. The opening value of the two-way valve (warm air valve) is 70 degrees, (there is condensed water at the bottom) circuit: temperature control valve, oil filter, if the oil temperature is lower than 70 degrees, the oil enters the oil filter and oil distributor through a straight path . Above 70 degrees, the warm air valve opens, enters the oil cooler, and then passes through the oil filter and the oil distributor.

Oil cut-off valve: a two-position normally closed valve to prevent oil from spraying out from the outlet of the main engine, the electricity is turned on, and the electricity is turned off.

One-way valve: prevent air from entering the main engine from the oil separation cylinder.

Relief valve: two-position normal-way valve, open when power is lost. Solenoid valve: three-phase solenoid valve, (control three valves) there are many types of air mobile compressor, according to the working principle can be divided into positive displacement compressor, reciprocating compressor, centrifugal compressor, positive displacement compressor working principle is The volume of compressed gas increases the density of gas molecules per unit volume to increase the pressure of compressed air; the working principle of centrifugal compressors is to increase the speed of movement of gas molecules, so that the kinetic energy of gas molecules is converted into pressure energy of gas, thereby Increase the pressure of compressed air. The working principle of a reciprocating compressor (also called a piston compressor) is to directly compress gas and discharge it when it reaches a certain pressure.

Commonly used air compressors are piston air mobile compressor, screw air compressors, (screw air compressors are divided into twin screw air compressors and single screw air compressors), centrifugal compressors and sliding vane air compressors Machine, scroll air compressor. The following is the definition of various compressors. Compressors such as cam type, diaphragm type and diffusion pump are not included because of their special purpose and relatively small size.

Speed type mobile compressor-is a rotary continuous flow compressor in which high-speed rotating blades accelerate the gas passing through it, thereby converting speed energy into pressure. This conversion occurs partly on the rotating blades and partly on the fixed diffuser or reflux baffle.
