CLK Airless oil projection system for conveyor roller chain lubrication

SKF ChainLube, CLK oil projection system The CLK airless oil projection system is the simple, reliable and easy-to-install solution for lubricating the roller chains of industrial conveyors. The system comprises a central unit with a reservoir, automatic system and volumetric pump for delivering a precise quantity of lubricant through projection nozzles to each point of friction of moving chain links. None of the system components is in mechanical contact with the chain, thereby eliminating any risk of wear and potential build-up of dirt. All components are corrosion-resistant. Nozzles and pipework...

Oil lubrication for roller chain Friction point The chains present a signiicant number of friction zones that should be lubricated. The illustration below represents the cross-sectional view of a roller chain with the various parts and friction zones. The lubricant penetrates between the various elements of the chain by gravity and capillarity. A lubricant ilm is formed at the friction zones of each element of the chain link. It reduces the temperature rise and thus the wear of parts. Chain speed The CLK lubrication system has been designed for lubricating horizontal roller chain conveyors with...

Central unit The compact central unit, with protection class IP 65, comprises three main elements: Oil reservoir The oil reservoir has a capacity of 7.5 litres. HDPE (high-density polyethylene) transparent plastic makes a visual oil level check possible. In addition, an electrical contact level sends a signal to the integrated control unit (LED and message on the display) once the minimum level has been reached and can also send an external signal to the machine command unit. Volumetric piston pump The volumetric piston pump delivers precise quantities of oil and forces them back to the projection...

Automatic lubrication The CLK lubrication system comprises an integrated control unit. This unit, which is easy to use, allows the user to set up their lubrication program according to their needs. The automatic lubrication process can be cyclical, semi-automatic or continuous. Cyclical lubrication A lubrication cycle comprises a lubrication phase, during which the lubrication points are lubricated, followed by a stand-by phase. Two parameters should be set: the duration of the lubrication cycle and the number of rollers in the chain that should be lubricated during the lubrication phase. The...
