Ruian Bokai Automotive Co.Ltd | Updated: Oct 24, 2017

The design highlight of the tunnel washing machine mainly studies the structure and control system of the tunnel automatic washing machine, and puts forward a control scheme and design of automatic car washing system based on PLC. The design adopts Siemens S7-200 CPU226 as the system control Core, the use of ultrasonic sensors and infrared sensors to detect the vehicle, the ultrasonic sensor output signal through the analog expansion module input PLC, infrared sensor, limit switch and the switch button signal in the form of digital input directly PLC, PLC output signal control the main washing Brush motor, spray water solenoid valve, hot air dryer and alarm devices.

Tunnel washing machine works: When the vehicle into the car wash room, after the automatic trajectory track, first by the high-pressure water knife completely washed out attached to the body of small sand and dust; and then sprayed high foam cleaning fluid and multi- Soft foam on the vehicle surface and contour for all-round package cleaning, and then sprayed on the surface of a body of water-soluble light agent (imported water wax), and finally by high-pressure air-dried, the whole process through the computer automatically control the brush car wash pressure and the power of work State, mainly for the appearance of a variety of small and medium-sized vehicles for high-pressure water rinse, scrub, wax washing, chassis cleaning, air-dry operations.

Tunnel Car Washing Machine Advantages:
