Abstract:
Element of a screw compressor injected with water containing two co-operating rotors (2-3) which are bearing-mounted in a housing (1), whereby this housing (1) limits a rotor chamber (4) in which the rotors (2-3) are situated and in which flows out a water circuit (11) for the injection of water, and which is provided with an inlet (5) and an outlet (6) and whereby the rotors (2,3) are supported, both on the inlet side and on the outlet side, on radial hydrodynamic slide bearings (18,19,25,26,) lubricated with water by means of axle journals, and are also axially bearing mounted on the outlet side, and whereby, on the inlet side opposite to the crosscut ends of the axle journals (13,16) is formed at least one chamber (20,21), wherein only on the inlet side, the chamber (20,21) which is formed opposite to the crosscut ends of the axle journals (13,16) is directly connected to a source (10,4) of fluid under pressure which is equal to at least 70% of the outlet pressure of the compressor element.
