Advantages of 2 Stage Rotary Screw Air Compressor
(1) Bigger Air Discharge
The two-stage compression PM VSD air compressor provides the industry with high air discharge. Compared with the same power air compressor, its exhaust volume is much larger. It can provide sufficient compressed air for your industrial production. Например: a 2-stage compression 90kW air compressor can replace an ordinary 110kW air compressor.
(2) Энергетически эффективный
We previously transformed a titanium chemical company. Also carried out data tests before and after the transformation. Use an air inlet energy efficiency analyzer for detection. According to the pressure and temperature, it is converted back to the air volume in the suction state. В то же время, measure the corresponding energy consumption. We use 2 stage screw compressor to replace the single stage one.
Their 132kW air compressors have the potential for transformation. And they run 24 часы. Transform the air ends of the four air compressors respectively. We adopted a two stage compressor airend. Use new 110kW motors and auxiliary parts. Также, we added 1 inverter cabinet. It can reduce the unloading loss during low peak air consumption time, and ensure that the pressure of the air compressor station is constant. It can reduce energy waste caused by unnecessary high voltage. In order to centrally control the air compressor, add a joint control box.
Before the transformation, the test data of four 132KW single-stage air compressors:

Actual Test Air Flow (м³/мин) | 22.8 | 23.5 | 22.7 | 23.3 |
Номинальный воздушный поток (м³/мин) | 25.2 | 25.2 | 25.2 | 25.2 |

After the transformation, the test data of 4 sets two stage rotary screw air compressor:
Test Item | SA132W | SA132W | SA132W | SA132W |

Подводить итоги: rotary air compressor 2 stage has a higher air flow. And power consumption is also less.
How much energy can a two stage industrial compressor save? Estimate based on actual measurement data:
Before the transformation, 4 original air compressors worked at the same time. The total air production is 92.3 м/мин. Total power consumption is 643.6kW.
After the transformation, 4 sets of two stage rotary screw air compressors were started. The total gas production is 110.9m/min. Total power consumption is 498.9kW. Air volume increased by 18.6m/min. Power consumption is reduced by 144.7 кВт.
Assume the air compressor runs 6000 hours per year. The electricity fee is 0.65 CNY/кВтч. The annual power consumption saving is 144.7×6000=868,200 kWh. The annual saving of electricity costs is 86.82×0.65=564,300 CNY. The power consumption per cubic meter before transformation is 643.6/92.3=6.97kW/(м/мин). The air volume to be increased is about 110.9-92.3=18.6m/min.
Calculate according to the current specific power consumption of 6.97kW/(м/мин). The annual cost of increasing air volume: is 6.97×18.6×6000×0.65=505,600 CNY/year. It is equivalent to saving electricity costs of 564,300 CNY+ 505,600 Юань= 1,069,900 CNY per year.
How Does Two Stage Rotary Screw Air Compressor Work
It combines two-stage compression rotors in one casing. And directly drive through helical gears respectively. Во-первых, air passes through an air filter into the first stage of compression. Then mix with a small amount of lubricating oil in the compression chamber. В то же время, the mixed gas is compressed to the interstage pressure. The compressed air enters the cooling channel and comes into contact with a lot of oil mist. Thereby greatly reducing the temperature. После, they enter the second stage compression chamber and perform secondary compression. They are compressed to final discharge pressure until discharged.
Часто задаваемые вопросы
Q1: What’s the biggest power of your 2 stage rotary screw air compressor?
А1: The biggest power of our two stage industrial compressor is 350 HP. То есть 250 кВт.
Q2: What’s the delivery time of your two compression rotary air compressors?
А2: The regular production time of our 2-stage industrial air compressor is 25 дни.
Q3: What is two stage screw air compressor?
А3: A rotary air compressor 2 stage is a type of industrial air compressor. It uses two stages of compression to compress air. The first stage compresses the air to an intermediate pressure. The second stage further compresses the air to the final discharge pressure. This design is more efficient than a single-stage compressor. Because it reduces the load on the second-stage compressor. So allow it to operate at a slower speed and reduce energy consumption.
