Two stage compression screw machine: characteristics and advantages of two-stage compression screw machine


 

Two stage compression screw machines often appear in motor production. Today, comps Compressor Co., Ltd. will introduce the characteristics and advantages of the next two-stage compression screw machine.

According to the theory of engineering thermodynamics, the constant temperature compression of the air compressor saves much work in the compression process. Moreover, constant temperature compression can not only reduce the work consumed, but also reduce the temperature of compressed gas, making the use of air compressor materials more broad and economical,. However, constant temperature compression requires that the heat of the gas exchange with the outside world at any time, and the gas temperature is equal to the outside world, which is impossible to achieve in practical work. The main way to reduce the exhaust temperature is to compress by stages and cool in the middle.

In addition, two pairs of rotors work at the same time, with fast pumping speed and large air output, which is an irreplaceable advantage of single-stage. Moreover, due to the two-stage compression, the compression of each stage is much smaller than that of single compression, the pressure on the rotor and bearing is small, and the rotor diameter is large and the speed is low, so the operation is reliable.

For the air output produced by the same power motor, the two-stage is generally 13-15% higher than the single-stage, which is equivalent to the air volume of a 90kw two-stage compressor that can produce a 110k single-stage compressor under the same energy consumption.
