Railway maintenance and repair of equipment, cleaning and degreasing
Rotajet spray washing machines and ultrasonic cleaning systems are used for degreasing and cleaning of large electric motors, wheel sets, bogies, brake callipers and brake systems, bearings and many more items prior to inspection and repair. Components are typically washed and degreased prior to stripping; typically this initial wash is performed in large Rotajet parts washer. The initial clean removes grease, oil and road dirt and make the units cleaner and easier to strip down. The stripped components are then washed again in a Rotajet spray washing machine using a non-alkaline detergent. For carbon removal from diesel engines Rotajet recommend that a caustic solution is used in a Rotajet dunk washing machine, for aluminium components Rotajet recommends cleaning and carbon removal in a Rotajet ultrasonic cleaning tank using a non alkaline detergent.
For washing aluminium and ferrous components, Rotajet recommend 1-512 detergent powder.
For washing and carbon removal ferrous components, Rotajet recommend 2-240 alkaline carbon remover.
For carbon removal from aluminium Rotajet recommend 1-550
