Air/oil lubrication system and method for monitoring and controlling air/oil lubrication systems

摘要

A system for the delivery and control of an air/oil mixture used to lubricate large bearings in heavy duty applications such as steel mills is provided. The system includes a mixing module for mixing air and oil and delivering the air/oil mixture through a plurality of connecting lines to a plurality of bearing housings. Each of the connecting lines or the outlet leading to the connecting line is, in turn, connected to its own individual solenoid. Each solenoid is connected to a common pressure transducer which is connected to a controller. The controller sequentially opens the solenoids one at a time thereby establishing communication between one of the connecting lines and the common transducer at a time. The transducer receives pressure signals fr6m each connecting line converts the pressure signals to analog signals before transmitting the analog signals to the controller. The controller then compares the signal received from the transducer with predetermined acceptable high low pressure values to ensure that the line is either not broken or not clogged.
