Introduction of double stage screw CZPT 
Double stage screw CZPT in the major areas with double screw,the compression approach 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 straightforward structure,flexible set up and large performance,but also highlights the positive aspects of their very own effective,energy-conserving:
1.can minimize the bearing load,increase volume performance,
two.in the case of some load procedure,can improve efficlency,vitality conserving.
Double screw CZPT than twin-screw compressor power conserving up to 15%,each and every run for 8000 hours a calendar year, Yearly savings of about 200 thousand yuan electrical power.
Edge of two phase screw CZPT 
one. Hierarchical compression to help save compression operate
Through the two-phase collection method, the CZPT one-stage compression procedure is divided into two compression processes. Such a method location can reduce the ratio of every one-phase compression procedure, which can efficiently lessen the compression and compression of every single phase screw. Essential drive power.
In the method of excellent gasoline compression, the sum of the electrical power necessary for solitary-stage pressure transmission and the electricity needed for multi-phase compression is equal, but in the actual compression method, due to a collection of aspects such as the transmission electricity reduction of the coupling, the friction coefficient of the bearing and the viscosity of the coolant With the enhance of the utilized power, the worthless electrical power exceeding the same ratio is created, so the ineffective power in the true compression process can be diminished by decreasing the compression ratio of every single phase, so that the sum of the power essential for multi-stage compression is much less than that of single-phase compression Needed electricity.
two. The intermediate heat oil cools and lowers the temperature of the fuel moving into the up coming phase. All the gas compression process is truly the process of the friction amongst the gas and the transferring elements and being compressed by it.
In the presence of friction, the fuel will rise in temperature thanks to friction, and there will inevitably be a trend of shadow accounts. This component of energy will be released in the sort of drive in the fastened quantity of air compression by increasing its possess force.
The temperature increase of the gas will increase the strain of the fuel by itself throughout the compression approach and increases the compression ratio. As a result, it is needed to pay additional energy to push the tools to shrink the air to the wanted pressure value. Therefore, the two-stage screw compressor is provided with a coolant injection curtain device.
