Product Description
Tinyard Enterprise Co.,Limited is one of the top level China auxiliary equipments of bottle making manufacturers and suppliers, welcome to wholesale auxiliary equipments of bottle making from our factory.Auxiliary Equipment for Blow Molding MachineAir compressor:Air compressor is the air source for PET stretch blow molding machine. As the main unit of PET production equipment, it carries out the process of compressing air from atmosphere to the required pressure. Generally we employ the reciprocating type multilevel air compressor that is composed of three pressing cylinders to compress the air to 10~35 bar gradually according to different requirements. The air compressor includes compressor head, motor and air storage tank with safety device, ect. The compressor head is driven to work by motor through V-belt conveyor. Through the air filter settled on the air inlet, the air inhales into the 1st stage cylinder where it is compressed to a certain pressure. After being cooled in the cooler, it flows into the 2nd stage cylinder and the 3rd stage cylinder in turn. Finally we get the air with rated pressure and the air will be stored in the storage tank for use. It is known that for bottle blowing, it needs up to 25~35 bar (for larger bottle, or the faster output. it will need 35 bar), while for the machine motion only around 8 bar is needed. Therefore two air compressors are ready for the different demands: high-pressure air compressor and the low-pressure air compressor.Air FilterApart from the water, there are also some corrosive impurities like carbon-hydrogen, tiny dust and solid particles, ect. Passing through the filter on the compressor, those mixed air will input into air compressor to be compressed, which will reduce the quality of the compressor' lubricating oil and evaporate part of the oil to go into the air pipe.During the air compressing, with high temperature and oxidation, the mixed compressed air will be acidic with high corrosive capacity. If this mixture is input into the air pipe, it will rust the pipe and pneumatic component seriously to stop the production and reduce the finish bottle quality, raise the maintenance cost. In consideration of those points, you need a high quality air filter to clear up those impurities out of the compressed air.Air dryerThe moisture in atmosphere usually turns on gaseous and hard to detect. After compressed in air compressor and cooled through pipe, it will be congealed water droplet together with oil and particle content out of air compressor. As a kind of water absorbing and oil sticking resin, PET molecule on the preform surface will absorb water and stick oil as soon as it meets the moist compressed air as air source. As a result, the PET bottle will has many flaws such as moist looking, slight drain marks, large shrinking rate and so on. At the same time, the moisture, oil and particle contents affect the pneumatic system and reduce its use life.From that point of view, it is very necessary to install a set of high efficient and high quality air dryer and air filter for high grade PET bottle production. The main function of the compressed air dryer is to remove the moisture from the compressed air and lower temperature of the compressed air in the heat exchanger, then the most part of the water vapor will be congeal water droplet and separated from air stream by a separator, finally the condensed liquid is discharged out of the unit.
