RAIL AUTOMATIC LUBE SYSTEMS – GAUGE FACE, RESTRAINING RAIL & TOP-OF-RAIL
FLO COMPONENTS STATIONARY OR WAYSIDE RAIL LUBRICATION SYSTEMS
A drastic increase in wear is prevalent on rails, wheels and switches on highly strained areas of track networks. Typical wear patterns in curves include slip-deformation on the inner rail (low rail) and lateral wear on the outer rail (high-rail). Also, noise emission is greatest through curves.
Stationary or Wayside, lubrication systems from FLO Components for rail flanks and rail heads lower noise emission and considerably reduce wear on rails, switches and wheels, reducing maintenance costs and increasing the lifespan of the rail network. FLO’s high-pressure systems enable the usage of NLGI 2 class grease, which offers exceptional adhesion to the rail and wheel as well as better lubrication properties.
FLO’s Lincoln wayside lubrication systems apply lubricant with a wiper bar that is flanged to the rail profile. The lube is accurately applied to the contact surface such as the gauge face or top-of-rail. Sensors detect and count the axles of the approaching train and initiate a lube event. The duration of the event which determines the lube supply, is adjustable and can be set to the applicable conditions.
A high-pressure pump supplies the wiper bars with an exact metered amount of lubricant. The lube is picked up by the train’s wheel circumference and evenly distributed on the rail contact area. Depending on the lubricant and application (gauge face or top-of-rail lubrication), the distributed lube is evident for kilometers beyond the lubrication station.
- High-pressure, low-volume pump ensures there is no clogging of lubrication ports.
- System effectively covers the rail with just enough lubrication = no waste.
- Exact metering of grease ensures each lube port receives the same small amountof grease every time without having to continuously “dial in” the system.
- Positive displacement design of divider block ensures a constant, metered volume of grease is delivered to each lube port regardless of back pressure or cold weather conditions.
Features of the Lincoln Pump to Port (PTP) Divider Block:
• Progressive-type, positive displacement design
• Fluid pressure from the pump pushes each piston to displace fluid to one port
• Cavity displacement is the same at varying temperature and pressure resistance
• Each port receives equal amounts of grease
APPLICATIONS FOR GAUGE FACE, RESTRAINING RAIL & TOP-OF-RAIL LUBRICATION
Gauge face lubrication reduces wheel flange friction
In curved sections, the high rail (outside) wheel runs on the gauge face. This contact results in semi-continuous friction that significantly causes wear to the wheel flange and gauge face. The strong contact friction between wheel and rail surfaces causes noise emission in the track curve. FLO’s gauge face lubrication system protects from friction and greatly reduces noise emission.
• Places grease high on the gauge face so it can be carried by passing wheel flanges and avoiding grease migration to the top of the rail.
• One gauge face system can supply several curves in succession.
• Brush holds excess grease to be picked up by the next train which minimies grease waste.
Top-of-rail (TOR) protection against the slip-stick effect
The path of the inner curve wheel is shorter and the wheel runs toward the rail middle causing tension. When the tension is greater than the frictional forces, the inside wheel jerks and slips. This slip-stick effect causes the inner wheel to shudder, resulting in screeching and wear on the running surface. This effect is especially prominent on very tight track curves. Applying a minimum amount of grease on the top-of-rail reduces both screeching and slip deformation.
Reduces noise emission from restraining rail friction
Restraining rails exist to support trains from derailing in curved-track situations. When the train begins the turn, the outside flange on the high rail side makes contact with the restraining rail. The friction from the contact creates high noise emission. FLO’s restraining rail lubrication system protects the rail from friction and greatly reduces noise emission.
