Problems solved by technology

[0011] The disadvantage of this method is that it only allows indirect control of the temperature of the injected liquid
[0012] Another disadvantage of the known method is that when a certain proportion of injected liquid is used to lubricate the bearing, the temperature of this liquid will be the same as that of the liquid injected into the compression space for cooling

Abstract

Method for controlling the liquid injection of a compressor device or expander device (1), whereby this compressor device comprises at least one compressor element or expander element (2), whereby the element (2) comprises a housing (3) that comprises a rotor chamber (4) in which at least one rotor (7) is rotatably affixed by means of bearings (8), whereby liquid is injected into the element (2), characterised in that the method comprises the step of providing two independent separated liquid supplies to the element (2), whereby one liquid supply is injected into the rotor chamber (4) and the other liquid supply is injected at the location of the bearings (8); and that the aforementioned separated liquid supplies are realised by means of a modular channelling piece of an injection module.

Description

technical field [0001] The invention relates to a method for controlling liquid injection of a compressor device. Background technique [0002] For example, it is known to inject a liquid, such as oil or water, into the compression space of a compressor element in order to cool a compressor arrangement. [0003] In this way, the temperature at the outlet of the compressor element, for example, can be kept within a range such that the temperature does not become too low, thereby preventing the formation of condensate in the compressed air, and thus the liquid temperature does not become too high, The liquid quality is thus maintained optimal. [0004] Injected fluid can also be used to seal and lubricate the compressor elements so that good operation can be obtained. [0005] It is known that the amount and temperature of the liquid injected will affect the efficiency of cooling, sealing and lubrication. [0006] Methods are already known for controlling the injection of l...
