FES(APM) Permanent Magnetic Frequency Conversion Screw Air Compressor Series

FES(APM) Permanent Magnetic Frequency Conversion Screw Air Compressor Series

# Cost Comparison

When purchasing air compressors, the traditional cost (i.e. purchase cost plus maintenance cost) accounts for only 25% of the total cost, while energy consumption accounts for 75%. Ordinary (frequency) air compressor is 23% – 30% .more energy saving than ordinary (frequency) air compressor Phil Sheng permanent-magnet inverter compressor (50Hz) than ordinary air compressor energy 30% – 40%. 

1. A 75Kw ordinary air compressor, running 8000 hours a year, electricity tariff of ¥.78 / degree, a year of electricity: 75KWx8000 hours x0.78 yuan/KW-h=46.8 million 

2. FerSheng permanent magnet inverter 75KW air compressor, a year can save about 35% of energy, total: 468 thousand yuan x35%=16.38 yuan. 

3. payback period years.

# How to reduce the energy consumption of permanent magnet frequency conversion screw machine?

1. Permanent magnet motor and the host with embedded integrated direct axis structure, compact structure, transmission efficiency of 100%. 

2. Eliminate the inefficient conversion from full load to unload, and avoid the power consumption. 

3. Reduce the average working pressure.

4. Reduce system leakage. 

5. Provide free choice of 4 to 13bar pressure to minimize energy consumption. 

6. The efficiency of permanent magnet motor is more than 20% higher than that of common motor at low speed.

Permanent magnet motor and compressor using embedded integrated direct axis structure, integration of motor and the height of the body system, the same transmission shaft design, bearing less motor support, more compact structure, no transmission losses and reduce the bearing friction loss, high transmission efficiency is up to above 100%. There is no motor bearing, thus eliminating the motor bearing fault point. Maintain fewer parts, improve reliability.

The use of computer platform controller, user-friendly interface, not only on the air compressor can be fully adjusted and monitored, while the network of high-end information technology, so that the remote network control into reality.

Special frequency conversion speed regulation system with open loop. By increasing the frequency of the frequency converter to start, eliminating the encoder, easy maintenance.

oil filter for Screw air compressor

The use of rotary filter, completely filter the impurities in the oil, with a built-in temperature control valve, to adapt to the temperature of the region, to ensure the quality of lubricating oil and oil pressure, easy to replace, no leakage of oil.
