1 General scheme

1.1 General summarize

Automatic Train Washing Machine adopts to clean the dust, oil stain and other besmirch

of the train. By using the water, cleaning agent and the brush to wash two lateral of the

railroad train, include the car door with the pane. The Automatic Train Washing Machine is

constituted by washing system, electricity control system, water supply system, compressed

air supply systems. It adopts the train self-draught. The train passes the warehouse to wash

and brush with the speed of 2-4 km/ h. Automatically proceeds railroad train two lateral

washing. Wash the bodywork surface to have no the dust, mud with the other attachment.

Wash the empress\'s water to pass by to handle to behind circularly use. Have the auto or

manual control function and can choose if use a cleaning agent.

1.2 This washing machine has the following functions:

1) This washing machine can auto wash the lateral extern surface.

2) This washing machine can auto wash the coping of the train.

3) This washing machine provides to automatically clean the train, meanwhile, manual

cleaning is also possible.

4) Each working section can work manually and move from point to point.

5) This machine provides to display the washing state of each working section, any

failures and relevant parameter.

6) This machine have the perfect system protecting function. It also provides to give

alarm both automatically and manually in the event of a failure.

7) This machine provides two alternative ways of washing: detergent solution washing

and fresh water washing.

8) This machine provides two alternative ways of drain or watering: auto and manual.

9) This machine provides the function: reuse the circulating water.

10) This machine provides the record function: the train’s number, washing times, if

using the detergent or not.

1.3 Working mode

The mode of the automatic train washing machine is “go washing mode”. The lateral

and coping of the train is washed when the train is going with the limited speed. The train

moves by its own power. The driver drive the train with the limit speed of 2-4km/h.

1.4 Constituting of equipment

Automatic Train Washing Machine consists of pre-cooling and pre-wetting station,

front .lateral detergent brushing washing station, roof detergent brushing station, lateral

initial water brushing station, water supplying station, the compressed air supplying

station, water circulating and disposing station, detergent supplying station, electric

appliances and control system.

All of the components tally with the international standard IEC, ISO, The Chinese

national standard GB and Railway Ministry of China standard TB are also adopted.

1.5 Work conditions for the equipment
