How is the two-stage screw air compressor energy saving?

10/17/2018

 
air compressor for PCR200DTH,INGERSOLL RAND CM351,ATLASO COPCO AIRROC D50 pneumatic crawler rock drilling rigs
​​The secondary compression rotor and the secondary compression rotor are combined in a housing and driven directly by helical gears. Natural air enters the first stage through an air filter and mixes with a small amount of oil in the compression chamber while compressing the mixture to the interstage pressure. The compressed gas enters the cooling channel and comes in contact with a large amount of oil mist, thus significantly reducing the temperature. The cooled compressed gas enters the secondary rotor for a second compression, which is compressed to the final exhaust pressure. Finally, the compressor is discharged through the exhaust flange to complete the entire compression process.

​​According to the theory of engineering thermodynamics, the compression process of an air compressor at a constant temperature saves the most energy. The lower the density of the gas at higher temperatures, the more work it takes to compress it. Besides, constant temperature compression can not only reduce the energy consumption but also reduce the temperature of compressed gas, making the use of air compressor materials broader and more economical, making the operation of air compressor more reliable. However, the constant temperature compression is necessary to make the gas heat exchange with the outside world at any time. It is an effective method to reduce the exhaust temperature utilizing fractional compression and intermediate cooling.
Besides, two pairs of rotors work at the same time, and the pumping speed is fast, and the output volume is large, which is a unique advantage of the single stage. Moreover, due to the two-stage compression, the compression of each stage is much smaller than that of the single-pole compression. The pressure on the rotor and bearing is small. Besides, the rotor has a large diameter and low speed, so the operation is more reliable.
For the output gas produced by the same power motor, the two-stage is generally 13% to 15% higher than the single-stage, which is equivalent to the output of a 110K single-stage compressed air compressor of 90KW under the same energy consumption.
​Check LIUTECH 650 two-stage screw air compressor has better performance of energy saving which can match with QIN-PCR200-DTH pneumatic crawler rock drilling rig,Atlas Copco AirROC D50 DTH pneumatic crawler rock drilling rig,HAN-D50-DTH pneumatic crawler rock drilling rig,Ingersoll Rand CM351 DTH pneumatic crawler rock drilling rig,Furukawa PCR200-DTH pneumatic crawler rock drilling rig,etc.
