The pet air compressor is the main part of the air supply device of the bottle blowing machine. It is a device that converts the mechanical energy of the prime mover (usually the motor) into the gas pressure energy. It is a special air pressure generating device for the bottle blowing machine after compressed air. The bottle blowing air compressor is mainly used in the supporting industry of bottle blowing machine.
Air compressor type and principle
There are many kinds of bottle blowing air compressor. According to the working principle, it can be divided into piston compressor, screw compressor and centrifugal compressor. The working principle of positive displacement compressor is to compress the volume of gas, increase the density of gas molecules in unit volume to improve the pressure of compressed air; the working principle of screw compressor is twin-screw compression, which transforms the kinetic energy of gas in the cavity of twin-screw compressor into the pressure energy of gas body, so as to improve the pressure of compressed air. The centrifugal compressor uses the impeller to rotate at high speed, so that the gas can be converted into gas kinetic energy under the condition of high-speed centrifugal, thus providing the pressure of compressed air.
How large air compressor is the bottle blowing machine equipped with? Recommended method by the bottle blowing machine manufacturer
The air compressor of bottle blowing machine is mainly used for low-pressure pre blowing and high-pressure bottle blowing of the bottle blowing machine, which is the necessary auxiliary equipment of the bottle blowing machine. According to the different output and power of the bottle blowing machine, the air compressors used are also different.
Then blow bottle machine with large air compressor, how to choose air compressor?
1、 Select air compressor decision parameters
1) . operating pressure, mainly referring to the exhaust pressure of air compressor, and considering the pressure drop of air pipeline and purification system
2) The selection of actual air consumption and air quantity should consider such factors as air consumption cycle, maximum air volume at the tip, air storage capacity, possible leakage and future expansion plan. Generally, it is better to use about 20% more than the actual amount.
2、 Size of air compressor for bottle blowing machine
One out two automatic bottle blowing machine: high pressure air compressor 1.2 / 3.0, low pressure screw machine 37KW, air tank 30kg
One out four automatic bottle blowing machine: high pressure air compressor 15kw, 2 sets, low pressure screw machine 15kw, air tank 30kg
One out six automatic bottle blowing machine: 2.0/4.03 high pressure air compressors
The above is the air compressor for bottle blowing machine. The air compressors configured by different manufacturers are slightly different. After all, the output of bottle blowing machine determines how much air compressor to use. Therefore, it is recommended that when you select air compressor, you should decide according to the output and energy consumption of bottle blowing machine.
