Variable Frequency Screw Compressor with Air Tank Air Dryer

 PRINCIPLES OF OUR VARIABLE FREQUENCY SCREW COMPRESSOR

A. Air path:

The air passes through 1 air filter, via 2 control valves, enters 3 compression chambers. then compressed by the screw to produce high-temperature and high-pressure oily air, which enters 5 oil-air separator for separation (centrifugal separation). the high-temperature gas passes 6 control valves to reach 7 cooling fans cooling, and then discharged through the control valve.

B. Oil path:

The lubricating oil in the oil-air separator passes through the 9 oil pipe and the 11 oil control valve, and reaches the 10 cooling fan for cooling. After cooling, the lubricating oil is filtered in the 12 oil filter to filter debris and dust generated during the operation of the air compressor. after then through the 13 oil control valve, enter 3 the compression chamber to lubricate the screw. While the screw is compressing the air, the lubricating oil is brought into the 5 oil-air separator to complete the oil circulation.

MAIN FEATURES OF OUR VARIABLE FREQUENCY SCREW COMPRESSOR: 

1. Stable air pressure
The variable frequency compressor utilizes the step-less speed regulation characteristics of the frequency converter, and can start smoothly through the controller or the PID regulator inside the frequency converter; it can quickly adjust and respond to occasions with large fluctuations in air consumption;
2. Start without impact
The frequency converter itself has the function of a soft starter. The starting current is within 1.2 times the rated current, while the power frequency starting is generally more than 6 times the rated current. Compared with the fixed frequency compressor, the starting impact is very small. This kind of impact is not only on the power grid, but also on the entire mechanical system, which will be greatly reduced.
3. Variable flow control
The variable frequency compressor inverter adjusts the motor speed in real time according to the actual air consumption to control the exhaust volume. So the variable frequency compressor can work in a wide range of displacement. 
4.The voltage adaptability of the AC power supply is better
A. Due to the over-modulation technology adopted by the inverter, it can still output enough torque to drive the motor to work when the AC power voltage is slightly low; when the voltage is slightly high, it will not cause the output voltage to the motor to be too high;
B. For self-generating occasions, variable frequency drive show its advantages obviously;
C. According to the characteristics of the VF of the motor (the variable frequency compressor works below the rated voltage in the energy-saving state), the effect is obvious for the site with low grid voltage. 
5. Low noise
Most of the working conditions of the frequency conversion system work at lower than the rated speed, the mechanical noise and wear of the main engine are reduced, and the maintenance time and service life are effectively extended.
