Introduction of double stage screw CZPT 
Double stage screw CZPT in the principal areas with double screw,the compression approach by the very first phase screw and CZPT screw by means of grading collection compression.
Double screw CZPT in addition to uphold twin-screw compressor has the benefits of basic structure,versatile set up and higher efficiency,but also highlights the rewards of their own productive,power-saving:
one.can reduce the bearing load,improve volume effectiveness,
two.in the circumstance of some load operation,can increase efficlency,energy saving.
Double screw CZPT than twin-screw compressor energy saving up to 15%,each run for 8000 several hours a year, Yearly personal savings of about 200 thousand yuan electrical energy.
Benefit of two phase screw CZPT 
one. Hierarchical compression to preserve compression work
By means of the two-stage series process, the CZPT single-phase compression process is divided into two compression processes. Such a approach placing can minimize the ratio of each and every one-stage compression procedure, which can successfully decrease the compression and compression of each stage screw. Required travel electrical power.
In the process of best gas compression, the sum of the power required for solitary-phase pressure transmission and the energy essential for multi-phase compression is equivalent, but in the actual compression procedure, because of to a series of factors these kinds of as the transmission electrical power decline of the coupling, the friction coefficient of the bearing and the viscosity of the coolant With the increase of the used pressure, the ineffective electricity exceeding the same ratio is produced, so the worthless electricity in the true compression method can be reduced by minimizing the compression ratio of every phase, so that the sum of the electricity necessary for multi-phase compression is less than that of one-stage compression Required electricity.
two. The intermediate heat oil cools and lowers the temperature of the gasoline coming into the next phase. All the fuel compression method is truly the process of the friction between the gas and the transferring parts and becoming compressed by it.
In the existence of friction, the gas will rise in temperature owing to friction, and there will inevitably be a development of shadow accounts. This part of strength will be introduced in the kind of power in the fastened quantity of air compression by rising its possess strain.
The temperature increase of the gasoline boosts the force of the gasoline alone for the duration of the compression approach and boosts the compression ratio. Consequently, it is necessary to spend added electricity to generate the equipment to shrink the air to the wanted force price. For that reason, the two-phase screw compressor is provided with a coolant injection curtain device.
