Methods for regulating liquid injection of a compressor device or expander device, a liquid-injected compressor device or expander device, and a liquid-injected compressor element or expander element

摘要

A method for controlling liquid injection of a compressor device or expander device (1), the compressor device comprising at least one compressor element or expander element (2), said element (2) comprising at least one rotor ( 7) comprising a housing (3) comprising a rotor chamber (4) rotatably attached by a bearing (8), wherein a liquid is injected into the element (2), the method comprising: Providing the element 2 with two independent separate liquid supplies, one liquid supply injected into the rotor chamber 4 and the other liquid supply injected at the position of the bearing 8, as described above. The separate liquid supply is realized by the modular channeling piece of the injection module.
