Introduction of double stage screw CZPT 
Double stage screw CZPT in the principal parts with double screw,the compression method by the initial phase screw and CZPT screw via grading collection compression.
Double screw CZPT in addition to uphold twin-screw compressor has the advantages of simple composition,adaptable set up and substantial efficiency,but also highlights the positive aspects of their own productive,energy-saving:
1.can lessen the bearing load,boost volume performance,
two.in the case of some load procedure,can boost efficlency,energy conserving.
Double screw CZPT than twin-screw compressor strength conserving up to fifteen%,every single operate for 8000 hours a calendar year, Annual cost savings of about 200 thousand yuan electrical power.
Benefit of two phase screw CZPT 
one. Hierarchical compression to help save compression operate
By way of the two-phase collection method, the CZPT one-phase compression process is divided into two compression procedures. This kind of a procedure placing can lessen the ratio of every single single-phase compression procedure, which can successfully minimize the compression and compression of each and every phase screw. Needed drive energy.
In the approach of excellent gas compression, the sum of the power required for one-phase pressure transmission and the electricity needed for multi-stage compression is equivalent, but in the actual compression approach, due to a series of variables such as the transmission electricity decline of the coupling, the friction coefficient of the bearing and the viscosity of the coolant With the boost of the utilized pressure, the ineffective energy exceeding the very same ratio is created, so the useless energy in the true compression approach can be lowered by decreasing the compression ratio of every single stage, so that the sum of the electrical power required for multi-stage compression is significantly less than that of one-phase compression Necessary electrical power.
2. The intermediate heat oil cools and reduces the temperature of the gasoline coming into the subsequent stage. All the fuel compression approach is in fact the method of the friction in between the gas and the shifting areas and becoming compressed by it.
In the presence of friction, the gas will increase in temperature thanks to friction, and there will inevitably be a craze of shadow accounts. This portion of power will be unveiled in the sort of pressure in the mounted quantity of air compression by rising its possess strain.
The temperature increase of the gas increases the pressure of the gasoline by itself for the duration of the compression process and raises the compression ratio. Therefore, it is essential to pay out extra power to push the products to shrink the air to the wanted strain benefit. As a result, the two-stage screw compressor is provided with a coolant injection curtain gadget.
