For the old piston air compressor, the general power is below 15kw, without frequency conversion.For the high-power variable frequency screw air compressor on the market, these machines generally use 5-10 years of the number of the majority.A considerable number of machines are faced with high energy consumption, high failure rate, high maintenance costs and other problems.3 elimination and replacement.Delia introduced permanent magnet variable frequency screw air compressor instead of three high altitude compressor.More replacement programs, extension electricity, extension maintenance and buyout programs.
 
Delia air compressor 30A
 
For the power screw air compressor in the market within 2-5 years, the power is about 37kw larger than the specification, it is recommended to consider frequency conversion scheme.But because of its massive use in two to five years.The actual work of the customer is also analyzed.Some client groups have machines that do not have frequency conversion and are quite energy efficient.
 
Case analysis of frequency conversion customer base:
 
1. Client a adopts draya screw air compressor DRC-100A, power frequency machine.Actual use 5 years, according to the machine control system parameters, the total running time 23,000 hours, load time 21,500 hours.The loading rate was calculated at 93%.This machine does not need frequency conversion and is already very energy efficient.
 
2. Customer b USES drdra-150a air compressor with power frequency of about 3 years.According to the display parameters, the total running time is 12000 hours, the load time is 3000 hours and the load rate is about 25%.This machine needs frequency conversion very much.
 
Air compressor energy saving system
 
In conclusion, it is necessary to comprehensively analyze and judge the frequency conversion transformation of the original screw air compressor according to the original operating conditions, operating environment and operating frequency, instead of blindly thinking that the frequency of all power screw air compressor is suitable for frequency conversion.
 
At the same time, the control system of power frequency air compressor is upgraded technically, and the motor is heat exchanger.
