Wheel Flange Lubrication and Rail Head Maintenance Systems
For all rail vehicles, from freight trains to streetcars, wear on the wheels and the rail is a major maintenance factor. The noise generated by wheels on tracks, especially in curves, adds environmental problems to the service needs of rail equipment.
A FluiLube wheel flange lubrication system will reduce wear on the rail and wheel while it cushions the noise load in curves in a very efficient way. FluiLube wheel flange lubrication offers innovative technology with tried-and-tested components and best cost-benefit-ratio.
BEKA developed the FluiLube system using thixotropic lubricating media with high solids content to achieve an ideal combination of adhesion and flowability in a spray lubricant for high-stress applications.
As a single-line system, FluiLube installations require no moving parts except the pump. This means:
- minimal wear
- simple maintenance
- low life-cycle costs
The FluiLube system corresponds to standard DIN EN 50 155 and 61 373.
The FluiLube Lubrication Procedure
Compressed air transports the lubricant along the interior tube walls to the lube point. The special mixing distributor divides the lubricant precisely to the different lube pints.
Spray nozzles slightly moisten the wheel flange with a highly adhesive lubricating film, which is transferred to the following wheels by the contact with the rails and which cannot be thrown off even with very high speed. The whole process is controlled by an electronic control or the control unit of the vehicle.
Innovative wheel flange lubricants with high solids content guarantee a reliable lubrication even with extreme temperature variations. This reduces noise and wear – proven by many applications!
The FluiLube Lubricant Pump
- Extremely rugged pneumatic pump, according to DIN EN 50 155 and DIN EN 61 373
- Aluminum container
- Standard container size 5,81 and 81 (special versions possible, welded according to DIN 6700)
- Level monitoring with dipstick, optional electronic
- Steady mixing of the lubricant
- Delivery rate 0.05-1.0 cm’/pulse
- Special paint possible
The FluiLube Mixing Distributor
The patented splitting insert of the FluiLube mixing distributor divides the lubricant. A porous insert collects the liquid particles, splits them up to tiny droplets (0, 15mm or less) and distributes them like a drizzle to the airstream.
This principle guarantees a homogeneous mixing ratio even with several spray nozzles.
The FluiLube Spray Nozzles
The FluiLube spray nozzles guarantee the lubrication of the wheel flanges even with very high velocities, without polluting other components like the brakes. The design of the spray nozzles depends on the application.
The FluiLube Control Unit
The FluiLube system is controlled by an electronic control unit. The compact and rugged controller allows the optimum adaption of the wheel flange lubrication to the operating conditions.
The optional curve sensor allows the curve-dependant control of the system. Conventional devices use inclination and centrifugal force, but the FluiLube sensor detects curves electronically.
The FluiLube Air Supply System
The FluiLube system is powered by either by the pneumatic system of the vehicle or by its own compressor. All components are protected by a control cabinet.
