1 Air-Oil CentralizedLubrication SystemsKeep in Motion! 2nd Edition 2007 A Lubrication system shouldalways be as modern andefficient as the machine it' Air-Oil Systems areideally suited for this becausethey offer: Optimal supply to the bearing Reduction in lubricant costs Environmental friendliness221312334 7 Air-Oil Centralized Lubrication SystemsIndexAir-oilSingle-line SystemAir-oilProgressive SystemAir-oil Centralized Lubrication Systems Air-Oil Mixing Distributor Valve Type AOl-FL Progressive Metering Device SSV and SSVD Air-Oil Mixing Block Type MB Air-Oil Metering Device Type ECOFLOW EFC Installation Assembly Reduced lubricant consumption.

2 Reduction up to 1/100th of the quantity when compared to grease Lubrication Continuous supply with fresh oil Increased bearing lifespan Positive pressure sealing of the bearing against contamination (water, dirt) Drastic reduction in maintenance costs; no cleaning of grease during bearing inspection No grease contamination of equipment, the working area and cooling water No misting of oil Environmentally friendly by simple disposal methods Oil and scale can individually be disposed of (clean separation)An oil pump supplies aprogressive or a single-linemetering device with oil.

3 Themetered quantities of oil from themetering device are supplied to amixing block that is connected tothe compressed air network. Theoil droplets in the line to thebearing are pulled apart in streaksby the flow of air. The airflow inthe middle of the tube transportsthe oil along the inner wall of thetube. The carrier compressed airexits the bearing andsimultaneously assists in sealingthe bearing.

This means, all injectorsare connected via a mainline tothe pump. The mainline isalternatively pressurized with oiland vented. Each injector outletcan be individually metered andthe function is visually monitoredvia a steel ball. In addition, theairflow is adjustable for eachoutlet.

Cleaning and disposal cost are reduced, as grease contamination of equipment, cooling water and the sinter is eliminated When comparing to oil mist Lubrication , the breathing air is not contaminated with micro oil droplets.

Thedistribution of oil to the mixingblocks occurs via SSV progressivemetering devices.

7 Depending onthe size of the system , the mixingblocks are available in two differentsizes. And, when different sizestrands are to be lubricated, SSVD metering devices may be used forthe oil distribution. The Air-Oil flowis then distributed to the lubricationpoints by ECOFLOW meteringdevices - which are also availablein two sizes: "S" (small),"L" (large).The large ECOFLOW meteringdevices are used as primary unitsthat supply the smaller meteringdevices. This reduces the totalnumber of mixing blocks, andprovides an even distribution forlarge the mixing blocks and theECOFLOW metering devices donot have moving parts, thuseliminating : Mixing BlockEFM: ECOFLOW Metering DeviceSSVD: Progressive Metering DeviceSection 1 Section 2 Section 3 Section 45131232 Air-oilProgressive SystemMetering Device SSVThe progressive metering devicesSSV supply the oil in meteredquantities to the mixing of outlets.

They are availablein 2 sizes: type and mixing blocks have 2 to 6outlets, and the have 2, 3or 4 outlets.
