All air compressors are divided into two types: reciprocating and screw, and many enterprises are faced with the problem of choosing a compressor. This choice affects not only the efficiency of the equipment, but also its final cost.
It is worth noting that recently there has been a great demand for screw models, which are gradually replacing piston ones. It is likely that the reciprocating compressor could even today become a relic of the past, if not for its attractive cost. In fact, piston models have certain disadvantages that screw ones are completely absent.
First of all, we are talking about a rather low level of reliability of such equipment, tangible vibrations, due to the constant reciprocating movements of the pistons, as well as the high cost and complexity of maintenance. All this, taken together, makes such equipment not as cheap and profitable as it seems at first glance. After just a year, maximum two years of intensive operation, a reciprocating compressor usually needs serious repair, while its scheduled maintenance is carried out all the time.
Screw compressors are devoid of all of the above disadvantages, especially if we compare their power indicators, the latter are in no way inferior to reciprocating compressors.
What are screw compressors?
Each one consists of a pair of screws, an air filter with a separator, a suction valve, an oil and cooling radiator, an electric motor and a thermostat. The air entering through the suction valve passes through the filter, and after cleaning it is supplied to the screw pair, where it mixes with oil and is pumped into the pneumatic system. Further, the air-oil mixture enters the separator, where it is separated into oil and purified air, which, in turn, goes out under pressure.
In the case when the buyer is firmly convinced that he intends to operate the compressor intensively and for a long time - more than 2-3 years - he can be recommended to opt for screw compressor equipment.
