Introduction of double stage screw CZPT 
Double phase screw CZPT in the principal elements with double screw,the compression process by the first stage screw and CZPT screw by way of grading series compression.
Double screw CZPT in addition to uphold twin-screw compressor has the positive aspects of simple composition,adaptable installation and substantial effectiveness,but also highlights the advantages of their own productive,power-preserving:
one.can minimize the bearing load,boost volume effectiveness,
2.in the circumstance of some load procedure,can increase efficlency,strength conserving.
Double screw CZPT than twin-screw compressor strength conserving up to 15%,each run for 8000 several hours a year, Yearly cost savings of about 200 thousand yuan electric power.
Advantage of two phase screw CZPT 
one. Hierarchical compression to preserve compression work
By means of the two-phase series method, the CZPT one-stage compression process is divided into two compression processes. This kind of a procedure setting can lessen the ratio of every one-phase compression approach, which can effectively decrease the compression and compression of every single phase screw. Essential travel electricity.
In the method of excellent gas compression, the sum of the electricity required for single-stage pressure transmission and the electricity necessary for multi-phase compression is equivalent, but in the real compression method, due to a sequence of aspects such as the transmission power reduction of the coupling, the friction coefficient of the bearing and the viscosity of the coolant With the enhance of the applied pressure, the worthless power exceeding the same ratio is produced, so the ineffective power in the genuine compression method can be lowered by decreasing the compression ratio of each and every phase, so that the sum of the electricity necessary for multi-phase compression is significantly less than that of one-stage compression Required electrical power.
two. The intermediate heat oil cools and lowers the temperature of the fuel coming into the next phase. All the gas compression approach is actually the approach of the friction among the gasoline and the relocating parts and being compressed by it.
In the presence of friction, the gas will rise in temperature owing to friction, and there will inevitably be a craze of shadow accounts. This portion of power will be unveiled in the sort of power in the set quantity of air compression by escalating its very own force.
The temperature increase of the fuel increases the strain of the gasoline itself throughout the compression method and raises the compression ratio. Therefore, it is required to pay out additional energy to push the gear to shrink the air to the wanted force worth. For that reason, the two-stage screw compressor is presented with a coolant injection curtain system.
