Compared to other types of compressor systems (for example, spiral -free rifle compressors) in spiral, smalled compressors completely absent oil in compressed air. Such equipment was widely used in those areas where, subject to all technical requirements, even a scanty amount of oil should be present in the air. Such industries include:
– pharmaceutical and chemical industry;
– food production.
Compressed air of an artisanal type, which is present in the described equipment, fully complies with the standards for these sectors. If you compare it with an oil compressor, it contains a large amount of water vapor, oil particles, dust, other harmful components.
How a spiral compressor works?
The application of the oil device in practice is dangerous, since there is a great risk of contact of finished products with harmful components, which can subsequently enter the human body. This problem is completely excluded when using spiral equipment. If a trunk filter and drainage is still installed in it, the exit is purified air of very high quality. In the process of operation of the described device, air compression occurs by moving a mobile spiral along a fixed spiral.
It is noted that in the spiral compressor element, the movements do not contact each other, therefore, oil enters the oil chamber entering the compression chamber. When the compression enters the compression chamber, the air is isolated and begins to compress. The moving spiral promotes the supply of compressed air to the very center of the chamber, after which it is replaced by the air line. The compressor element is driven by the electric motor.
A spiral compressor working without oil is very reliable and durable, its design is designed in such a way that the load on the spiral elements are distributed evenly. The equipment is characterized by a low noise level, which cannot be said about similar screw and piston -type devices, a long service life.
Technology for the production of spiral installations is very expensive and very complicated. If they are present in the assortment of products of a particular manufacturer, this indicates its high technological level, the production of only high -quality and reliable equipment.
