The prime movers of centrifugal air compressor mainly include motor, steam turbine and gas turbine. Due to the differences in power source, structural design and maintenance work, the three prime movers have their own advantages. Users should choose them according to the nature of conveying medium and the difficulty of solving power source. The advantages and disadvantages of three kinds of prime movers for frequency conversion transformation of air compressors are introduced as follows:
1、 Motor
Motor is one of the prime movers commonly used in centrifugal compressor. It has the advantages of simple structure, small maintenance workload and convenient operation. But the motor speed is not high, can not directly meet the high speed requirements of the compressor, if the gas is flammable and explosive gas, we must also add explosion-proof measures or choose explosion-proof motor.
2、 Steam turbine
The high speed of the steam turbine can directly meet the requirements of the high speed of the compressor. Generally, there is a stable steam supply system in the chemical plant, and when transporting flammable and explosive gases, continue to read surrogate materials http://yiniao.org.cn/ It does not need explosion-proof facilities. However, the steam turbine has many auxiliary equipment, complex structure, heavy maintenance workload and technical difficulty, and complex start-up operation, which requires high technical quality of operation and maintenance personnel.
3、 Gas turbine
Gas turbine does not need complicated auxiliary equipment, occupies less land, uses less electricity and water, and can be used in the field. However, it is expensive and requires high technology in manufacturing and maintenance.
