To date, manufacturers supply a fairly large assortment of various models of air compressors. However, when choosing such equipment for industrial needs, one should be guided not by the model but by the type of compressor, based on the conditions in which this equipment will be used. important is its price, economy in use, performance.
Today, two types of compressors are among the most popular for application, and production activities, these are screw and reciprocating industrial air compressors. The main decision will therefore be between a screw or a piston unit. Both types have many advantages and disadvantages. Thus, a reciprocating air compressor is the cheapest in comparison with a screw compressor, but the efficiency of a screw compressor is close to almost one hundred percent.
MAIN FEATURES OF INDUSTRIAL AIR COMPRESSOR
For the same capacity, a screw compressor uses about 25% less electricity than a piston-type compressor. This is due to the fact that piston models of compressors have a so-called "dead zone" in which significant losses of already compressed air occur, while screw models do not have this, therefore, and their cost is lower.
Also, the choice of an industrial air compressor should include parameters such as the cost of electrical energy when using it. It is not difficult to calculate the electricity costs for compressor maintenance. For example, a compressor works, consuming 30 kW of energy per hour, thus for a working day, and this is about eight hours it will be 240 kW, respectively, that for a working month, for about 21 days it will be 5040 kW. Accordingly, with this method of calculations, downtime and similar nuances were not taken into account, in which the compressor unit remained in an inoperative position, but on average it turns out to be something like this. And if we take into account the fact that a reciprocating compressor still consumes 25% more electricity than a screw compressor, while delivering the same amount of compressed air, then the choice is obvious.
STRUCTURAL DEVICE OF INDUSTRIAL AIR COMPRESSOR
Depending on which work area this equipment will be used on, it may have different design features. As a rule, the complete set of industrial compressor equipment includes such devices as air treatment , all kinds of filtration systems, aspiration systems and the like equipment in combination with which the operation of industrial-type compressors will be the most productive and efficient.
Industrial air compressors can be classified in the same way in terms of capacity, and are low, medium and high capacity compressors. Here the choice of the compressor depends on the volume of compressed air required, which is required from the compressor. The average output of an industrial screw air compressor is about 4700 liters per minute.
