General air compressor gas production and power ratio, in the most popular words is: every 1 kW of power, about every minute can produce 0.15 to 0.18 cubic meters of compressed air. On the other hand, if you want the machine to spit out 1 cubic meter of gas per minute, you need to consume about 5.5 to 7 kW of electricity.
Give some practical examples to help you understand. A 3.7 kW machine, about 0.63 cubic meters of gas per minute. A 7.5 kW machine produces about 1.38 cubic meters of gas per minute. A 37 kW machine, about 6 cubic meters of gas per minute. You will find that basically every 6 kW of power corresponds to 1 cubic meters of gas per minute, which is relatively close to most screw machines.
This ratio is actually the "specific power" in the industry. The lower the value, the more energy the machine saves, and the same one-time power produces more gas.
Water-lubricated air compressors have a small advantage in this matter. Because it uses water instead of oil for lubrication and sealing, the friction resistance inside the machine is smaller than that of the traditional oil-lubricated machine, so under the same power, the gas production of the water-lubricated air compressor will be slightly higher, or it will need slightly less power to achieve the same gas volume. At the same time, because there is no resistance loss of oil, the gas output is more stable, and the gas volume will not be large or small due to changes in oil temperature.
In general, just remember an approximate number: 1 kW power is about 0.16 cubic meters of gas per minute, or vice versa, 1 cubic meter of gas per minute requires about 6 kW power. Water lubricated air compressor can save a little on this basis.
If you want to know whether the specific power of your existing equipment is power saving, you can continue to talk.
The calculation method of air compressor gas production involves many factors. The following is a detailed summary of the calculation method of air compressor gas production: 1. basic calculation formula Formula 1: gas production (m & sup3;/min)= input pressure (MPa)× exhaust volume (m & sup3;/m
The maintenance cycle of the screw air compressor usually depends on the use of the equipment and the manufacturer's recommendations. Generally speaking, the maintenance cycle of the screw air compressor can consider the following aspects: Operating hours: Many manufacturers recommend running the equipment for a certain number of hours
The oil content in the exhaust of an air compressor is usually expressed in ppm(parts per million, parts per million) or mg/m & sup3;(milligrams per cubic meter). These two units are used to quantify the oil content of oil and gas mixtures, but their measurement methods and tables
The oil content of the 1. is different. 1. Oil and no oil in the air compressor generally refer to the oil content of the gas discharged from the exhaust port of the air compressor. Generally, the oil content of the oil machine is larger. 2. The oil content of the oil-free machine is 0.01ppm, so use this oil content
There are significant differences in industrial grade and food grade standards for compressed air, which are mainly reflected in the design focus, manufacturing materials, filtration system and regulatory compliance. The following is a detailed comparison of these two types of standards: 1. design key industries
In the field of semiconductor manufacturing, the cleanliness of compressed air directly affects the quality of chip production and equipment stability. The industry usually requires compressed air to meet extremely high purity standards to avoid the interference of small impurities in precision processes. Granklin Water Lubricated Single Screw Air
The working time of the air compressor is affected by many factors, including the use of the environment, the way of use and the maintenance of the equipment. The following is a specific analysis of these factors: Use environment: Environmental factors such as temperature, humidity and air quality will affect
Oil-free air compressor is a kind of air compressor without adding lubricating oil. Its main purpose is to provide pure and pollution-free air compression source. The following are the main application areas and specific uses of oil-free air compressors: 1. main application areas Medical industry: in the pharmaceutical industry
According to the oil content of the exhaust gas, the air compressor can be divided into oil air compressor, micro oil air compressor and oil free air compressor. The following is a detailed analysis of the oil content of these three air compressors: 1. oil content of oil air compressors: oil air compressors will
Water lubricated oil-free air compressor, screw integrated machine in order to save space and installation pipeline, the compressor, air storage tank, refrigerated dryer, filter integrated into one, equivalent to a miniature air compressor station. This model is mainly used in hospital dentistry, hyperbaric oxygen chamber, laboratory, electronics, semiconductor, wine, beverage, food packaging, laser cutting and other occasions requiring pure air and small-scale gas supply.
