Working principle of variable frequency compressor: Due to the relationship between the speed of the air compressor motor and the actual power consumption of the air compressor as a power source, reducing the speed of the motor will reduce the actual power consumption. The variable frequency air compressor pressure sensor instantly senses the system and gas pressure. Through accurate electrical control and variable frequency control, the motor speed (that is, power output) is controlled in real time without changing the air compressor motor torque (that is, the ability to drag the load), and by changing the compressor speed, responding to pressure changes, and maintaining a stable system pressure (set), high-quality air is output on demand. When the system consumption is reducedThe compressor provides compressed air consumption greater than the system, the variable frequency compressor can reduce the speed, while reducing the output of compressed air; and increase the speed of automobile transportation to increase compressed air, maintain a stable system pressure value. It and the water pump fan motor power, according to the load change, control the input voltage frequency converter, and the same principle energy saving effect is as follows:
1. The pressure setting of the variable frequency air compressor can be a point. The minimum pressure required by the production equipment is the set pressure. The frequency of the compressor is based on the pressure fluctuation trend of the pipeline network and the speed of the air conditioning compressor. It can even eliminate the unloading operation of the air compressor to save electricity.
2. Since the variable frequency makes the pipeline network pressure stable, it can reduce or even eliminate pressure fluctuations, so that the air compressor running in the system can operate at a pressure that meets the production requirements, reducing the power loss caused by pressure fluctuations.
3. Since the compressor cannot exclude the possibility of long operation time at full load, the capacity of the motor can only be determined by the maximum demand, and the design capacity is large. In actual operation, the proportion of light operation time is very high. If variable frequency speed regulation is adopted, the operation efficiency can be greatly improved. Therefore, the energy saving potential is great.
4. Some regulations (such as adjusting the valve opening and changing the blade angle, etc.) cannot reduce the motor power even at low demand. With variable frequency speed regulation, when the demand is low, the speed of the motor can be reduced, and the power of the motor can be reduced, thereby further achieving energy saving.
5. Most single motor drive systems cannot be adjusted continuously according to the weight of the load. Using variable speed, it can be conveniently adjusted continuously, and the pressure, flow, and temperature stability can be maintained, thereby greatly improving the working performance of the compressor.
