Briefly explain how the frequency conversion of air compressors is achieved
Release time:
2019-01-09
For older piston air compressors, the power is generally below 15kw and no variable frequency conversion is required. For high-power inverter screw air compressors on the market, the number of these machines generally used for 5-10 years accounts for most of them. A considerable portion of the machines face high energy consumption, high failure rate, and high maintenance costs.3 Phase-out and replacement. Delia has introduced permanent magnet inverter screw air compressor to replace three high air compressors. There are more replacement options, such as splitting electricity, splitting maintenance and buying out options.
Tria Air Compressor 30A
For market use within 2 to 5 years power screw air compressor with power greater than the specification about 37kw, it is recommended to consider inverter solution. But due to its large-scale use within 2 to 5 years. The actual working condition of the customer should also be analyzed. Some customer groups have machines without inverter conversion, which are also quite energy efficient.
Example analysis of inverter conversion customer group.
1. customer a uses draya screw air compressor DRC-100A, an industrial frequency machine. The actual use of 5 years, with reference to the machine control system parameters, the total running time of 23,000 hours, the load time of 21,500 hours. The load rate is calculated as 93%. This machine does not need frequency conversion and is already very energy efficient.
2. customer b uses a drdra-150a air compressor with about 3 years of industrial frequency. According to the displayed parameters, the total running time is 12,000 hours and the load time is 3,000 hours, with a load rate of about 25%. This machine is in great need of variable frequency.
Air compressor energy saving system
In summary, it is necessary to conduct a comprehensive analysis and judgment according to the original operating conditions, operating environment and operating frequency of the original screw air compressor for frequency conversion, rather than blindly think that all power screw air compressor frequency suitable for frequency conversion.
At the same time, in the technology of industrial frequency air compressor control system to upgrade, while the motor fan heat exchange.
