Common types of air compressor hosts mainly include the following:
scroll type air compressor:
working principle: Through the meshing of the fixed scroll and the movable scroll, a plurality of compression chambers are formed, and two staggered spiral blades are used to compress the air, so as to realize the suction and compression of the gas.
Features: simple structure, small footprint, low noise, long service life, but high sealing requirements.
Screw air compressor (including twin screw type):
working principle: Mainly rely on the rotation of the rotor and the increase of the cogging volume to inhale. The gas is pressed into the exhaust end through the mutual meshing of the male and female rotors, and finally discharged through the exhaust port.
Features: It has the advantages of high reliability, simple structure and high efficiency.
Shanghai Granklin Group's "water-lubricated screw air compressor" has the characteristics of high gas cleanliness and water-lubricated air compressor head.
piston type air compressor:
working principle: The air is compressed by the reciprocating piston to obtain high-pressure air.
Application: Pneumatic tools commonly used in small machines, workshops and vehicles, such as nail guns, paint spray guns and stamping machines.
Features: small size and low price, so it is widely used in small equipment and machines.
centrifugal air compressor:
application: Mainly used in occasions that require high flow, such as water treatment, power and chemical industries.
Features: high efficiency, low noise, high reliability, and can provide high pressure and high flow of air.
membrane type air compressor:
application: Mainly used in the medical and pharmaceutical fields, because it can provide dry and clean air, and will not produce oil and dust.
Features: It can filter and separate impurities in the gas to ensure the purity of the air; because there is no lubricating oil and piston, it is very suitable for applications with high purity requirements.
In summary, different types of air compressors have their own characteristics and advantages according to their working principles and application scenarios. When choosing an air compressor, it is necessary to make a decision according to the specific needs and working environment.
Air compressor can be used at rated flow, but the specific use of the situation also need to consider a number of factors. First of all, the rated flow of the air compressor is the gas compressed and discharged per minute under the standard state (usually the gas temperature is 20 ℃, the relative humidity is 0, and the pressure is atmospheric pressure).
1ppm oil content corresponds to milligrams per cubic meter (mg/m & sup3;) The value needs to be calculated according to the molecular weight, temperature and pressure of the oil. The simplified formula under standard conditions (0 ℃, 101325Pa) is: mg/m & sup3;= 22.4M ×ppm, where m is the molar mass of oil (g/mol)
The buffer tank of the air compressor belongs to the pressure vessel. The buffer tank is one of the important parts of the air compressor. Its main function is to reduce the pulsation in the exhaust process of the air compressor, convert the pressure energy of the gas into kinetic energy, and reduce the vibration of the pipeline. To achieve this effect, the buffer tank
There is no fixed standard for the oil content of compressed air oil. It usually depends on the type, design, use environment and maintenance conditions of the compressor. The micro-oil air compressor is designed to control the oil content in the compressed air as much as possible.
0.01 g/m & sup3; The moisture content of the air coming out of the cold dryer is usually not more. However, please note that the air outlet pressure dew point of the cold dryer is 2~10 ℃ at 0.7 Mpa, which is equivalent to the atmospheric pressure dew point of -23 ~-16 ℃, and the water content at this time is about 0.82~1.48 g/m & sup3;.
Air compressors are common equipment used in industrial production to compress air to provide power or perform other process operations. Screw air compressor is one of the widely used types, but in addition to the screw type, there are several main types of air compressor: piston type air compressor
The central role and special requirements of air compressors in the food industry 1. power support and equipment drive The air compressor provides stable air source power for the food production line and drives the operation of key equipment such as filling machine, bottle blowing machine and inkjet printer. For example, in the beverage filling
Oil-free screw air compressor is through pure water to lubricate the unit, cooling compressed air. Therefore, the quality of the gas compressed by the oil-free screw compressor is higher. However, in fact, the oil-free screw air compressors that everyone sees in ordinary work are also equipped with them.
Air compressor exhaust oil content standards may vary due to different air compressor types, uses and industry standards. Generally speaking, for ordinary air compressors, the oil content in the exhaust should not exceed a certain limit to ensure the quality and air quality of the compressed air.
In an electronics factory, have you ever wondered how those complex electronic devices are made? One of the indispensable links is the use of air compressors. Air compressor is like the "energy station" of electronic factory, providing various equipment
