Rail lubrication

Purpose

In 2010, TVEMA created a rail lubrication car exceeding the capabilities of existing analogues in terms of functionality, due to the use of modern high-tech rail lubricating equipment and intelligent software. To lubricate the rail top, a unique lubricant supply system was developed, the operation of which is performed based on the route data formed on the basis of the nameplate databases.

Lubrication system

The lubricant tanks capacity is 1200 liters. Two loading modules on both sides of the car ensure the loading of lubricant drums, with a total capacity of 2 m³. Filling system filters rule out the grease contamination. Each of the supply tanks is equipped with instruments for determining the amount of mixing for the lubricant. The turnaround run for a single filling with lubricant is up to 5000 km. Specific consumption of lubricant per 1 km of curved rail being lubricated is 0.15-0.35 l regardless of the car speed.

Rail lubricating installation

It has a hydraulic lubricant supply (main and backup), with pneumatic lubricant supply.  

The installation includes:

- refilling system;

- two supply tanks for lubrication;

- compressor with a receiver;

- automatic lubricant supply system to the nozzle with the ability to control from GPS/GLONASS or gyroscopic pickup (as a backup control);

- nodes of lubricant supply to rails, with heating system of

- external pipeline and nozzles.

Advantages

- Unique lubricant supply system;

- Low specific consumption of lubricant per 1 km of rail being lubricated;

- Long turnaround run with a single filling with lubricant (up to 5000 km);

- Automatic lubricant supply system to the nozzle with the ability to control from GPS/GLONASS or gyroscopic pickup;

- Heating system for lubrication supply units;

- Video surveillance system for monitoring the application of lubricant.

Our rail lubrication car, operating as a part of postal-baggage and passenger trains, is additionally equipped with diagnostic equipment. In the course of the main function (lubrication of rails), it also conducts their diagnostics.

Scope of application

The network of railways of the Russian Federation and CIS countries.
