Rotajet spray washing equipment is used throughout the rail industry for washing and carbon removal from large traction motors
Rotajet D series front loading spray washers are used for washing stators and cases from large traction motors which are contaminated with oil, grease and carbon deposit. Rotajet “Flushmaster” is fitted with a removable lance which is located in the traction motor cases. The Rotajet spray washer will wash the motors internally and externally within a cycle time of 15 minutes. The standard D60 Rotajet washing machine will accommodate 4 large motors. The machine is typically a two stage wash and rinse machine, using a heated water based detergent @ 65-70oC. After the washing cycle the extraction fan is engaged which ensure any steam is removed from the washing cabinet and also speeds up the flash drying process. After washing the traction motors are either dried in a vacuum oven or on a conventional drying oven.
Rotajet spray washing and parts washing machines can also be used for reconditioning smaller electric motors.
