FIELD: refrigeration engineering.
SUBSTANCE: airtight compressor contains a vertical cylindrical casing 1, in the upper part of which there is an electric motor 2, connected to the shaft 4 by means of a rotor 5, cylinders 3 located in the lower part of the casing 1, a silencer 6, a mount 7 located at the bottom of the casing 1, for installing the compressor in a vertical position. A plate 9 of a rectangular shape with holes 10 is installed by the upper surface of the casing 1 in its central part, on racks 8 of circular cross section, which are arranged in rows. A frequency converter 11 connected to the electric motor 2 is attached to the plate 9 with the possibility of removal. By means of rods 12, an additional fastening is attached to the side surface of the casing 1, made in the form of two parallel plates 13 with holes located in the longitudinal direction for installing the compressor in a horizontal position.
EFFECT: invention is aimed at ensuring the operation of an airtight compressor from AC networks with an AC frequency of 400 Hz, 50 Hz, fastening a frequency converter, and the possibility of placing it in a horizontal position.
