Double - stage compression screw machine: double - stage compression screw machine working characteristics


  Two-stage compression screw machine is one of the main mechanical power equipment of many enterprises. Now two-stage compression screw machine often appears in motor production. The following compus compressor introduces the working characteristics of the two-stage compression screw machine.

According to the theory of engineering thermodynamics, constant temperature compression of double - stage compression screw machine is very economical. Constant temperature compression can not only reduce the consumption of work, but also reduce the temperature of the compressed gas, so that the use of double-stage compression screw machine material is more broad and economic. But constant temperature compression, it is necessary to make the gas heat exchange with the outside world at any time, the gas temperature is equal to the outside world, in the actual work is impossible to achieve. It is an effective method to reduce the exhaust temperature by using two - stage compression screw machine and intermediate cooling.

In addition, the two-stage compression screw machine two pairs of rotor work at the same time, pumping speed, large gas output, this is a single stage irreplaceable advantages. Because the compression of each stage of the two-stage compression screw machine is much smaller than the single compression, the pressure of the rotor and bearing is small, coupled with the large diameter of the rotor and low speed, so the operation is reliable.
