System and method for a compressor
First Claim
1. A method for a compressor system, comprising:
- operating the compressor system to compress air from a first stage compressor into an intermediate stage reservoir, to deliver air from the intermediate stage reservoir to a second stage compressor, and to further compress the air in the second stage compressor into a primary reservoir;
monitoring an intermediate stage pressure of the intermediate stage reservoir; and
identifying a condition of the compressor system through recognition of a change in the monitored intermediate stage pressure during a time period in which the compressor system is operated relative to a stage of a cycle of the compressor system; and
generating a control signal in response to identifying the condition of the compressor system, wherein the control signal operates the compressor system or generates an alert.

Abstract
Systems and methods of the invention relate to diagnosing a compressor. A method may include operating a compressor to compress air from a first stage compressor into an intermediate stage reservoir, to deliver air from the intermediate stage reservoir to a second stage compressor, and to further compress the air in the second stage compressor into a primary reservoir, monitoring an intermediate stage pressure of the intermediate stage reservoir, and identifying a condition of the compressor through recognition of a change in the monitored intermediate stage pressure during a time period in which the compressor is operated. A vehicle system is also provided including an engine, a compressor operatively connected to the engine, and a controller that is operable to identify a condition of the compressor.

13. A system comprising:
-
a compressor system comprising;
a first stage compressor configured to compress air into an intermediate stage reservoir at a first pressure, and a second stage compressor configured to receive air from the intermediate stage reservoir at the first pressure and further compress the air into a primary reservoir of the compressor system at a second pressure, wherein the second pressure is greater than the first pressure; anda controller configured to; receive a signal corresponding to a monitored intermediate stage pressure of the intermediate stage reservoir of the compressor system; and identify a condition of the compressor system through recognition of a change in the monitored intermediate stage pressure during a time period in which the compressor system is operated relative to a stage of a cycle of the compressor system; and generate a control signal in response to the condition of the compressor system that is identified, wherein the control signal operates the compressor system or generates an alert. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21, 22, 23)
