In the industrial production process, compressed air is widely used in various fields。Air compressor as the main equipment of compressed air, its operating cost has been concerned。其中,Air-electricity ratio of air compressorIt is an important parameter, which directly affects the power consumption of the air compressor and the cost of compressed air。So, how to calculate the gas-electricity ratio of the air compressor?This article will give you a detailed answer。
First, what is the air compressor gas to electricity ratio?
The gas-electric ratio (Kw/Nm3) refers to the amount of electricity required for each certain amount of compressed air produced by the air compressor。In other words, the gas-electricity ratio is the ratio of the power of the air compressor to the output of compressed air。The lower the gas-electricity ratio, the lower the energy consumption of the air compressor, and the lower the cost of compressed air。
Second, how to calculate the air compressor gas to electricity ratio?
1, determine the rated power of the air compressor
The rated power of air compressors is usually expressed in kilowatts (kW)。When purchasing an air compressor, it is necessary to pay attention to its rated power so that it can be used in subsequent calculations。
2. Measure the compressed air output of the air compressor
Compressed air production refers to the amount of compressed air produced by the air compressor in a certain period of time, usually expressed in cubic meters per minute (m3/min) or nitrogen cubic centimeters per second (Nm3/s)。In practical applications, the compressed air output can be calculated by measuring the outlet pressure and flow rate of the air compressor。It should be noted that different models of air compressors may have different measurement methods, so it is necessary to refer to the manual of the equipment or consult a professional when calculating。
3. Calculate the gas-electricity ratio
Gas-electric ratio = rated power of air compressor/compressed air output
For example, if the rated power of an air compressor is 22kW and the compressed air output per minute is 50m3/min, then the gas-electricity ratio of the air compressor is:
Gas-electric ratio = 22kW / 50m3/min = 0.44kW/m3∅∅
Third, how to reduce the air compressor gas to electricity ratio?
There are many ways to reduce the gas-electricity ratio, here are some suggestions:
1, improve the exhaust efficiency of the air compressor: by optimizing the exhaust system of the air compressor, improve the working mode of the compressor, etc., the exhaust efficiency of the air compressor can be improved, thereby reducing the gas-electricity ratio。
2, the use of energy-saving air compressor: choose air compressors with high efficiency and energy saving characteristics, such as frequency conversion air compressors, permanent magnet synchronous motor air compressors, etc., can reduce the gas-electricity ratio under the premise of ensuring the quality of compressed air。
3、 Reasonable control of the operating temperature of the air compressor: The operating temperature of the air compressor has a great relationship with its power consumption。In general, the higher the operating temperature of the air compressor, the greater the power consumption。Therefore, reasonable control of the operating temperature of the air compressor can effectively reduce the gas-electricity ratio。
4, regular inspection and maintenance of the air compressor: regular inspection and maintenance of the air compressor can ensure its normal operation and avoid the increase in energy consumption caused by equipment failure。
In short, mastering the method of calculating the gas-electricity ratio of air compressors can help enterprises control the cost of compressed air more effectively and improve production efficiency。I hope this article can provide you with useful information and wish you better results in your work!
