SYSTEM FOR MONITORING AND CONTROL OF THE CIRCULATION LUBRICATION OF THE BEARINGS OF CYLINDERS AND ROLLS IN A PAPER MACHINE

摘要

A system for control and monitoring of the circulation lubrication of the bearings of the revolving cylinders and rolls in a paper machine or equivalent in which lubrication oil is fed from an oil-lubrication center or centers through a system of pipes into lubrication points. From these lubrication points, the lubrication oil is passed back through a system of return pipes into the oil-lubrication center or centers. The system includes actuator panels placed and grouped in the vicinity of the lubrication points primarily above the floor level of the paper machine hall or equivalent. From the actuator panels, lubricant feed pipes are passed to several lubrication points placed in the vicinity. The actuator panels have a feed-back connected regulation loop for lubricant flow quantity provided for each lubrication point, which regulation loop includes an oil-flow regulation valve, an actuator motor for same, as well as an oil-flow measurement device and a regulation circuit.
