Application status of compressed air in the industrial area
Compressed air is one of the most widely used power sources in the industrial field. It has many advantages such as safety, environmental protection, good regulation performance, convenient transportation, convenient centralized management and application, and good adaptability of working environment. According to statistics, the air compressor system consumes about 8-10% of the industrial energy consumption, and the national air compressor consumes about 300 billion k.h/a, of which the effective energy consumption only accounts for 66%, and the remaining 34% of the energy. (about 102 billion kW.h/a) was wasted, and the air compressor system needs to be efficiently carried out.
Baosi independent research and development and years of accumulation of two-stage screw air compressor technology combined with the actual working conditions of users, relying on a sound production quality control system, strong technical research and development strength and a huge sales service system. Constantly developed a twin-screw compressor product that meets market demand and quickly won the recognition of users and the industry.

Example of energy saving inverter on the screw air compressor:
For example, a 55kW ordinary two-stage screw air compressor has an average gas production of only 70% of the rated displacement. (Note: Please pay attention to this sentence, meaning that the model purchased by the user can produce 10 cubic meters of gas consumption, while the actual gas consumption only accounts for 70%, which is 7 cubic meters). If you run 5,000 hours a year, the electricity bill is 1.1 yuan per kW / h. The normal machine will generate two losses, which are calculated as follows:
1. No-load loss = 30% unloading time * No-load loss generated during no-load (45%*55kW/h*5000 hours/year*1.1 yuan/kWh=40837.5 yuan/year
| No-load running time/year: 30%*5000 hours=1500 hours |
| No-load operation energy consumption = rated power *45% rz 24.75kW |
| No-load loss: 0.45*55*(0.3*5000)=37125kW |
| Electricity cost calculation: 37125kW*1.1 yuan / degree = 40837.5 yuan |
2. Differential pressure loss = 70% loading time * higher than 2bar (kg) pressure loss (14% * 55kW / h* 5000 hours / year * 1.1 yuan / degree = 29,645 yuan / year)
| Load run time / year: 70% * 5000 hours = 3500 hours |
| 2bar differential pressure is higher than energy consumption = running time* (14%*55kW) 26950kW |
| Electricity bill calculation: 26950kW * 1.1 yuan / degree = 29,645 yuan |
About 7% of energy consumption per 1 bar of pressure
In summary: no-load loss + differential pressure loss = the cost savings for the user is about 70482.5 yuan
Two-stage power frequency energy efficiency value
The meaning of specific power is the amount of electricity consumed per cubic volume of intake air (in the state per minute)!
Algorithm example:
(8bar energy saving algorithm) Input power of our BLF90-811: 20m3 X6.1kW/( m3/min)=122kW The specific power of single-stage compression XX110kW is generally about 7.3, and its input power is 20m3X7.3kW/(m3/min) =146kW
Full load energy saving rate: (146-122) / 146 z 16.4% Annual operation 5000 hours to calculate power saving: 120000kW
If the customer uses lower pressure, the pressure value per 1 bar can be reduced, and the specific power value is reduced by 7%. The full load of gas does not change much! (6bar energy-saving algorithm) BLF90-8II’s 6 kg input power can be 20m3X6.1kW/(m3/min)X (1-14% (2bar drop pressure) =-105kW
The specific power of single-stage compression XX110kW is generally 7.3X (1-14% (2bar drop pressure)), and its input power is 20m3X6.28kW/(m3/min) z125.6kW
Full load energy saving rate: (125.6-105) / 125.6 = 16.4% Annual operation 5000 hours calculation Power saving: 103000kW electricity
