How to improve energy saving efficiency of 30kw screw air compressor
1. Since the possibility of long-term operation under full load cannot be ruled out, the capacity of the motor can only be determined according to the maximum demand, so the design capacity is generally large. In actual operation, the proportion of time spent on light loads is very high. The use of frequency conversion speed regulation can greatly improve the working efficiency during operation. Some adjustment methods, even in the case of small demand, can not reduce the operating power of the motor. After the frequency conversion speed regulation is adopted, when the demand is small, the rotation speed of the motor can be reduced, and the operating power can be reduced, thereby further realizing energy saving.
2. Most of the single motor drive systems can not be continuously adjusted according to the weight of the load. After the frequency conversion speed regulation is adopted, the continuous adjustment can be conveniently carried out, and the parameters such as pressure and flow rate can be kept stable, thereby greatly improving the air compressor. Work performance.
3. The variable frequency control system has precise pressure control capability. Match the air pressure output to the desired amount of air. No longer frequently loaded and unloaded, the output air volume of the variable frequency control air compressor changes as the motor speed changes. Since the accuracy of the frequency control motor speed is improved, it can keep the system pressure variation of the pipe network constant, and effectively improve the quality of the working condition.
