Self service car washing machine is an important type of car washing machine, widely used and highly praised by users. Technically speaking, this equipment belongs to fully automatic car washing machine. Do you know how to evaluate self-service car washing machine? Below we will discuss the eight criteria for evaluating the quality of a self-service car wash machine: 1. Shoot and start the pump to start billing, stop the gun and stop the pump to stop billing, be sensitive in response; Technically speaking, does this involve a flow meter or a flow switch? What is the issue with the flow switch? On the other hand, there are some self-service car washing machines on the market where the water pump still works or is charged when the gun is stopped. This is very unreasonable. If the gun is turned off and the water pump continues to work, the pump head will heat up and the sealing ring will burn out after more than 10 minutes. The car owner needs to run to the machine and press the pause button to stop it. Moreover, even though the car owner has stopped washing the car, they are still charging, which is unreasonable! So any self-service car wash machine with start and pause buttons is considered a non intelligent machine. 2. Stop water detection function. If the tap water stops, the machine should be able to detect it. Small experiment, turn off the water pipe and insert a 1 yuan coin into the coin slot. Eating the coin indicates that it does not have the function, while not eating it indicates that it has the function. 3. Start with low water pressure. In many places, the water pressure of tap water is relatively low, or well water is pumped out from a water tank or tower. Self service car washing machines controlled by flow meters cannot quickly recognize it and need to use flow switches to control it. 4. The workmanship of the shell. Chuangwang is made of 1.5mm galvanized steel plate sprayed with plastic, with a weight of 160KG and a shell cost of over 2000. It can be exposed to wind and rain when thrown outside; And those that use iron sheet paint, such a large filing cabinet costs only four or five hundred yuan, and will rust off after being placed outside for six months. 5. Winter antifreeze. The three major components of antifreeze are: 1) insulation material, 2) built-in constant temperature heating device, which is an oil tank, and 3) pipeline emptying. The high-pressure pipe is thrown outside the machine, and there is insulation and oil inside the machine to prevent freezing, but the water in the pipeline will freeze outside. Even with the installation of an automatic receiver, if the gun tip is exposed to a little water, it will still freeze. It is crucial that all pipelines can be emptied. 6. Length and quality of high-pressure pipes. The high-pressure pipe on a typical water pump is 8 meters long, while a self-service car wash machine is unmanned, and the car owner's car cannot be parked in a designated location like a beauty salon, either far or near. Therefore, an 8-meter pipe is not enough, while the one on the King of Adventure is 16 meters long. In addition, pipes are inevitably crushed by vehicles, so steel wires must be installed inside to prevent pressure. 7. Internal electrical control. There are various solenoid valves on the waterway, and for safety reasons, they should be 12V. Suggest going to the manufacturer to open the cabinet door and check the nameplate of the solenoid valve for clarity. 8. Filling method of foam. The common foam filling method is to use the foam's own gravity to connect the foam bucket with the water inlet end of the pump through a conduit, and adjust the mixing ratio of foam and clean water through the flow control valve; When there is not much foam left in the foam bucket, it is difficult to press foam into the water inlet end of the water pump, that is, foam cannot be used up. This way of conquering the king has unique techniques that have been avoided. {1} {2} {3} {4} {5} {6} {7} {8}
