Publication number: 20160265530Abstract: Air compressor systems, upgrade kits, computer readable medium, and methods for controlling an air compressor for improved performance. The methods may include receiving a working air requirement; determining an estimated air pressure of the air compressor to deliver the working air requirement; measuring a pressure of the air compressor; comparing the measured pressure with the calculated estimated air pressure; if the measured pressure of the air compressor is greater than the determined estimated air pressure by a predetermined greater amount, then decreasing an output control of the air compressor; and if the measured pressure of the air compressor is less than the calculated estimated air pressure by a predetermined lesser amount then increasing the output control of the air compressor. The air compressor may be controlled based on a measured pressure of delivered working air. An oil control system may shut off oil to parts of the air compressor.Type: ApplicationFiled: April 12, 2016Publication date: September 15, 2016Applicant: Sandvik Intellectual Property ABInventors: Grant Andrew FIELD, Simo TANNER, Karl INGMARSSON

Publication number: 20150275897Abstract: Methods, computer readable media, and apparatus are disclosed for decompressing an air compressor. The methods including compressing air, the compressed air flowing through a first path through a first non-return valve to a first receiver; and in response to determining to take the air compressor off-load, closing an air inlet valve of the air compressor to stop air from entering the air compressor, opening a second path from the air outlet of the air compressor to approximately atmospheric pressure to lower the air pressure at the air inlet of the air compressor, stopping a first flow of oil from the first receiver to the air compressor, wherein the first flow of oil is for cooling the compressor, stopping a second flow of oil from a separator for a working air to the air compressor, and flowing oil from the first receiver to the air compressor for lubrication.Type: ApplicationFiled: September 20, 2013Publication date: October 1, 2015Inventors: Grant Andrew Field, Simo Tanner
