Washing the rail wheel pairs

Proper care and maintenance

The lifespan and functionality of a freight cars depend on how often and how thoroughly the car is cleaned and maintained. Cleaning and maintenance intervals depend on the intensity of use, the operating environment, and the level of soiling. Given the current situation, only the companies bringing efficiency enhancement into focus will survive and succeed. IPAX is well-managed company and has moved from emphasis on customizing items to offering globally standardized products that are advanced, functional, reliable, and low priced.

Cleaning process

This technological process is typical for rail car repair enterprises (railcar repair depots and railcar repair plants). The major contaminants are ISO14001 greases thickened with potassium soaps.

Products for cleaning of underfloor equipment of the railcars shall be certified by Green Seal as well as included in the list of agents specified in the guidance documents and compliant with the ISO standards. IPAX Unikleen 200 is certified by Grren Seal and included in a range of guidance documents and the state standards.

Usually wheel and bearing servicing areas of the repair depots are equipped with special jet washing chambers for axle box washing. This type of washing equipment in the case of its proper operation allows to achieve high quality cleaning. Process solution tanks are equipped with a bypass system allowing to separate floating hydrocarbon contaminations.

Attention paid to general cleanliness of external and internal surfaces of the axle boxes.

Principle of process organization

The wheel pair arrives to the wheel and bearing servicing area, where it is pressed out, then the axle boxes are sent to the jet washing chamber. Washing time and concentration may depend on the state of equipment and washing temperature. The most common washout time is from 3 to 5 minutes, and the concentration of solution is from 1% to 3%.

Solutions advantages

– Cost saving up to 80%
– Enhanced cleaning quality
– Enhanced safety of the personnel
– Lower temperatures of the process solution
– Absence of taint and corrosion after washing
– Simplification of the process
– Improving the environmental friendliness of the cleaning process
– Reduced frequency of the process solution disposal
