Introduction of double stage screw CZPT 
Double phase screw CZPT in the principal parts with double screw,the compression method by the first phase screw and CZPT screw through grading collection compression.
Double screw CZPT in addition to uphold twin-screw compressor has the benefits of easy framework,flexible set up and high performance,but also highlights the advantages of their very own efficient,vitality-saving:
one.can lessen the bearing load,improve quantity effectiveness,
2.in the scenario of some load operation,can increase efficlency,strength preserving.
Double screw CZPT than twin-screw compressor energy preserving up to 15%,every run for 8000 hours a year, Annual cost savings of about 200 thousand yuan electrical power.
Gain of two phase screw CZPT 
1. Hierarchical compression to conserve compression function
By means of the two-stage collection procedure, the CZPT solitary-phase compression method is divided into two compression processes. Such a approach setting can decrease the ratio of each and every one-phase compression procedure, which can efficiently lessen the compression and compression of each stage screw. Needed drive electrical power.
In the approach of ideal gasoline compression, the sum of the energy necessary for single-stage strain transmission and the energy necessary for multi-stage compression is equal, but in the genuine compression method, because of to a series of factors this kind of as the transmission electrical power reduction of the coupling, the friction coefficient of the bearing and the viscosity of the coolant With the boost of the applied drive, the worthless energy exceeding the identical ratio is created, so the worthless electricity in the true compression method can be reduced by lowering the compression ratio of every stage, so that the sum of the electrical power needed for multi-stage compression is much less than that of solitary-phase compression Essential electricity.
2. The intermediate warm oil cools and decreases the temperature of the gasoline moving into the next phase. All the gas compression method is actually the procedure of the friction in between the fuel and the transferring parts and becoming compressed by it.
In the existence of friction, the gasoline will rise in temperature because of to friction, and there will inevitably be a pattern of shadow accounts. This part of strength will be unveiled in the type of force in the set volume of air compression by increasing its possess force.
The temperature increase of the fuel raises the pressure of the fuel by itself in the course of the compression method and increases the compression ratio. Therefore, it is required to pay out extra electricity to drive the products to shrink the air to the desired strain worth. For that reason, the two-stage screw compressor is supplied with a coolant injection curtain gadget.
