PurgeX Infrared Sensing Lubrication Systems utilize sensing technology to achieve a high level of precision when oiling chains. Lubrication of critical areas of the chain at critical times prolongs chain life, reduces waste, minimizes contamination, and improves safety.  These systems are equipped with 1 to 12 patented PurgeX pumps, a 3-way air solenoid, infrared photo sensor, and programmable logic device.  The entire unit is housed in a compact, hinged-door NEMA 12 enclosure.  It requires only compressed air, electricity, and lubricant to begin operation. 

Targeted Lubricant Delivery

Both high speed and low speed chains can pose a challenge for lubrication.  The situation can be further complicated by fluctuating chain speeds.  Continuous application of oil tends to saturate the open areas of the link, with only a portion of the lubricant reaching the critical friction area at the pin.  The infrared signal helps identify the position of the pin as the chain is moving.  The cycling of the lubrication pump is synchronized with the sensor, placing the oil directly on the targeted area.

Scheduled Lubrication Cycles

The PLC utilizes the signal from the sensor to count chain links.  This provides the ability to lubricate the chain during one compete rotation without overlap.  It also allows the PLC to be programmed to lubricate only after a specific number of chain rotations.

PurgeX Infrared technology is excellent for any application requiring precise lubrication, and is especially suitable for high speed applications.  Specific uses include general purpose automation; conveyors, robotics, packaging, paper, printing, folding, gluing, and binding machines, food industries, food and beverage filling, assembly equipment, textile, chemical, petroleum, marine and lumber manufacturing.
