WD-40 products are used in the rail transit industry

problem

Rail transit has become a powerful magic weapon for large cities to solve traffic congestion problems. The timely maintenance of subways and light rails has become very important. How to reduce the position of vehicle machinery and circuit components and ensure the safety of trains? For example: three-track receivers for subway vehicles The retreat device will appear to be "locked to death" or "rebound is not in place", which will pose a safety hazard to the operation of the subway.

solution

1. WD-40 products efficiently maintain the mechanical parts of subway vehicles

Â·Lubricate the shaft head of the locomotive compartment

Â·Lubricating the track of the locomotive

Â·Dehumidification protection of locomotive circuits and electrical appliances

Â· The locomotive's bolts and nuts are protected against rust. For rusted bolts and nuts, it can be easily loosened.

2. WD-40 product maintenance three-track receiver

The retracting device of the three-track receiver is mainly composed of a fixed shaft and a moving sleeve. After running for a period of time, the nylon bushing in the moving sleeve wears, hindering the movement of the moving sleeve, and it is easy to form a "locked" state of the retracting device. The direct clearance of the fixed shaft and the movable sleeve is extremely small (6-8 micrometers). Generally, the oil film of the lubricating oil is easy to stick to the oil film, and it is difficult to achieve the lubricating effect.

WD-40 dehumidification anti-rust lubricant has strong permeability and the film is not sticky after drying. WD-40 solution can penetrate into the fine gap of the metal connection of the retractor of the receiver, keep it well lubricated and prevent â€œhugâ€ Dead state, to ensure its normal operation.

income

WD-40 products can keep the mechanical parts of subway or light rail vehicles in good working condition, protect electrical and circuit components from moisture, remove moisture, reduce component failures, and ensure safe operation of vehicles.
