Tunnel car washer is the main force in the car washer Market at present. Many customers do not know the design highlights and the specific price of the equipment after buying the tunnel car washer. How much money to buy the appropriate equipment is confused by many customers. Madise analyzed the following technical design, so that consumers can better understand the highlights and price range of the design:
The highlight of the design of tunnel car washer is mainly to study the structure and control system of Tunnel Car washer. A control scheme and design of automatic car washer system based on PLC are proposed. This design uses Siemens S7-200 CPU226 as the core of system control, uses ultrasonic sensor and infrared sensor to detect vehicles, the output signal of ultrasonic sensor is input into PLC through analog expansion module, infrared sensor, limit switch and switch button signal are directly input into PLC in digital form. The output signal of PLC mainly controls washing brush motor, spray water solenoid valve, hot air dryer and alarm device.
After the system is powered on, the infrared sensor detects the vehicle to be washed and inputs the signal to the PLC. The PLC outputs the instruction to start the whole system. When the vehicle to be washed is on the guide rail, the guide rail tracts the vehicle to move slowly. When the vehicle enters the washing area, the roller brushes and spraying devices are started. The ultrasonic sensor detects in real time to ensure the accuracy of the roller brushes movement and controls them at the same time. The spraying device sprays in real time; when the vehicle enters the drying area, the hot air drying equipment starts drying operation in time; when the vehicle moves out of the drying area, the whole washing process ends. In addition, when the system runs normally, the operation panel indicator lights display normally; when the system fails, the alarm device sounds, reminding workers to clear the fault.
The price of tunnel type car washing machine: the price of tunnel washing machine is between 20 and about 300000. The tunnel washing time is basically 1.5 minutes -2 minutes. The cost of washing a car depends on the local conditions. According to the amount of water per ton, it is 10 yuan, and the water charge is one yuan, plus the cost of foam and water wax, which adds up to less than 2 yuan.
