Abstract
In case of the wildly using of screw compressors in modern industries, the compressor efficiency improving methods’ development are actual. The main advance of the «dry» screw compressor comparing with oilinjected compressors is their compact due to the no needs huge oil system, which includes oil separation system and additional filters, which leads to improving an ecology and reducing the exploitation coast. One of the way of the compressor capacity and energy efficiency improving is developing of the rotor profile gaps’ calculation methodic by taken into account different factors determined by the compressor working conditions. The heating load on the «dry» screw compressor parts higher than on the oil-injected compressor parts, because their working conditions lead to the highest value of the discharge temperature. Therefore, it is necessary to take into account compressor rotors’ temperature fields to calculate rotors’ profile gaps correctly. This paper presents the methodic of the rotors’ temperature field calculation with the aim to reduce the rotors’ profile gaps and improve the «dry» screw compressor efficiency.
