US 2020/0386228 A1 · STEAM COMPRESSOR COMPRISING A DRY POSITIVE-DISPLACEMENT UNIT AS A SPINDLE COMPRESSOR

Abstract

The invention relates to a spindle compressor designed as a twin-shaft rotary displacement machine for delivering and compressing flow media, particularly steam. It comprises a pair of spindle rotors in a compressor housing (1) comprising an inlet collecting space (11) and an outlet collecting space (12). The centre distance of the pair of spindle rotors is at least 10% longer on the inlet-side end than on the outlet-side end. Each of the two spindle rotors (2, 3) is driven by an electric motor (18, 19), and an electronic synchronisation controls the electric motors (18, 19) such that the spindle rotors (2, 3) rotate in a contact-free manner.

Dependent claims

A spindle compressor as a 2-shaft rotary positive-displacement machine, working without operating fluid in the working space, for conveying and compressing gaseous conveyed media, preferably steam, comprising a spindle rotor pair in a compressor housing (1) which has an inlet collection chamber (11) and an outlet collection chamber (12),

characterised in that the centre distance of the spindle rotor pair at the inlet-side end is at least 10% greater than at the outlet-side end, in that each of the two spindle rotors (2, 3) is driven by an electric motor (18, 19), and an electronic synchronisation controls the electric motors (18, 19), and in that the spindle rotors (2, 3) rotate contact-free.

Dependencies are inferred from the claim text.
