Introduction of double stage screw CZPT 
Double stage screw CZPT in the major elements with double screw,the compression approach by the first stage screw and CZPT screw by means of grading series compression.
Double screw CZPT in addition to uphold twin-screw compressor has the advantages of easy framework,versatile installation and higher effectiveness,but also highlights the benefits of their possess efficient,energy-conserving:
one.can minimize the bearing load,boost volume efficiency,
two.in the case of some load operation,can improve efficlency,vitality preserving.
Double screw CZPT than twin-screw compressor energy preserving up to fifteen%,every operate for 8000 hrs a calendar year, Once-a-year cost savings of about 200 thousand yuan electrical power.
Benefit of two phase screw CZPT 
one. Hierarchical compression to help save compression operate
By means of the two-phase sequence procedure, the CZPT solitary-phase compression method is divided into two compression procedures. This kind of a method placing can reduce the ratio of every single solitary-phase compression process, which can efficiently reduce the compression and compression of every phase screw. Required push energy.
In the process of ideal gasoline compression, the sum of the electricity required for single-stage force transmission and the electricity needed for multi-phase compression is equivalent, but in the real compression process, due to a series of aspects this sort of as the transmission energy loss of the coupling, the friction coefficient of the bearing and the viscosity of the coolant With the boost of the used pressure, the ineffective power exceeding the exact same ratio is produced, so the useless power in the real compression method can be lowered by decreasing the compression ratio of every single phase, so that the sum of the power essential for multi-stage compression is considerably less than that of one-stage compression Essential power.
two. The intermediate warm oil cools and minimizes the temperature of the fuel getting into the next stage. All the fuel compression method is in fact the approach of the friction among the gasoline and the relocating parts and being compressed by it.
In the presence of friction, the fuel will increase in temperature because of to friction, and there will inevitably be a craze of shadow accounts. This part of energy will be unveiled in the form of force in the set volume of air compression by escalating its own force.
The temperature rise of the fuel boosts the strain of the gasoline itself during the compression method and increases the compression ratio. For that reason, it is needed to shell out additional power to drive the equipment to shrink the air to the preferred force value. Consequently, the two-phase screw compressor is offered with a coolant injection curtain system.
