An automated lubrication system for large industrial use delivering high pressure lubrication from a pumping unit to a manifold for disbursement in metered quantities for maintenance operations synchronized through logic control to regular operations of equipment to prevent or minimize interference.

A method of monitoring industrial valve actuation and maintaining an industrial valve by lubricating it on-demand and in coordination with in-service valve operations through an automated system eliminating downtime and/or exposure of personnel to hazardous environments through centralized lubricant supply and spent fluid collections.

The oil air supply system includes a lubricant oil supply pipeline, a compressed air supply pipeline, a mixing device which distributes lubricant oil supplied from the lubricant oil supply pipeline in a fixed amount and mixes the lubricant oil with compressed air to generate oil air, a plurality of oil air supply pipelines which supply the oil air to a plurality of bearings of a main spindle device respectively, a flow rate sensor provided in the lubricant oil supply pipeline and detects the flow rate of the lubricant oil, a pressure sensor provided in the compressed air supply pipeline and detects the pressure of the compressed air, and an abnormality detection device which detects supply abnormality of lubricant oil based on a detection signal output from the flow rate sensor and detects supply abnormality of compressed air based on a detection signal output from the pressure sensor.
