Abstract

FIELD: compressor engineering. SUBSTANCE: compressor has a shaft actuated by an electric motor the rotor of which is mounted on the shaft. The shaft is provided at least two stages with working wheels between which the electric motor is interposed. An intermediate cooler is connected between the stages with the working wheels. The shaft is set in bearing members composed of at least one supporting bearing with air or gas lubricant and self-adjusting rotatable segment supports which are provided with ceramic supporting surfaces. EFFECT: enhanced efficiency.

Claims (1)

Компрессор содержит вал с приводом от электродвигателя, ротор которого установлен на валу. На валу установлены по меньшей мере две ступени с рабочими колесами, установленные на валу с отделяющим их друг от друга продольным промежутком, в котором расположен электродвигатель. Между ступенями с рабочими колесами подсоединен промежуточный охладитель, а вал установлен на опорных средствах, содержащих по меньшей мере один опорный подшипник с воздушной или газовой смазкой и самоустанавливающимися поворотными сегментными опорами, которые снабжены керамическими опорными поверхностями. Компрессор обладает исключительно высокой эффективностью и ввиду отсутствия масляной смазки подшипников особенно хорошо подходит для использования в тех случаях, когда необходимо обеспечить "сухой воздух", то есть не допустить загрязнения рабочего газа.The compressor comprises a shaft driven by an electric motor, the rotor of which is mounted on the shaft. At least two stages with impellers are installed on the shaft, mounted on the shaft with a longitudinal gap separating them from each other, in which the electric motor is located. An intermediate cooler is connected between the steps with the impellers, and the shaft is mounted on support means containing at least one support bearing with air or gas lubrication and self-aligning rotary segment bearings, which are equipped with ceramic bearing surfaces. The compressor has extremely high efficiency and, due to the lack of oil lubricated bearings, it is particularly suitable for use in cases where it is necessary to provide “dry air”, that is, to prevent contamination of the working gas.
