Abstract
A system and method for regulating lubricant flow in a variable speed compressor includes a compressor having an inlet for gas to be compressed, at least one lubricant injection line, and an outlet through which compressed gas and lubricant exit, a flow control interface comprising at least one valve for regulating the flow of lubricant through the lubricant injection line, and a control logic in communication with the compressor such that the operating speed of the compressor is communicated to the control logic and the control logic is in communication with the flow control interface such that the control logic sends a signal to the flow control interface to open or close the at least one valve depending on the predetermined optimum lubricant flow rate for the compressor based on its operational speed. This allows the flow of lubricant through the compressor to be varied in response to the operating needs of the compressor at different speeds.
