With the popularity of cars, the number of individuals choosing car wash machines is also constantly increasing. But do you know what factors should be considered when choosing a car wash machine? Below, we will introduce the factors to consider when choosing a personal car wash machine:
⑴ Car washing environment space. The car washing space for urban customers is very small, and due to the proximity of neighboring cars, it is not advisable to pursue high pressure. It should be sufficient. Low pressure car washing machines should be considered.
⑵ Risk factors: Personal car washing machines are household products, and wives and children who do not know how to operate them may come into contact with them. Excessive pressure may cause injuries to the eyes, ears, nose, and mouth.
Products with high pressure and flow rates consume a lot of electricity, and if a cigarette lighter interface is used, there is a possibility of burning out the onboard circuit. Considering the safety factor, the rated current of a personal car wash machine using a car power supply should generally not exceed 6A, which is equivalent to 72W/12V.
Although high-power car washing machines on the market have extremely high pressure, their electrical load can reach up to about 1500W, and the peak input current of the car washing machine may be as high as 25 A. Users who purchase such products must consider the load of their own power lines and the allowable current value of the electricity meter, otherwise there is a possibility of tripping and line burnout.
a) The current carrying capacity of aluminum core insulated wires with various cross-sections is about 9 times the number of cross-sections. For example, a 2.5mm 'wire with a current carrying capacity of 2.5 × 9=22.5; (A) A 1 square millimeter copper wire can carry a current of 1 x 9=9A.
b) The permissible current for a typical household electricity meter is 5 A-10A (for houses built 10 years ago) or 15-25 A (for newly constructed houses).
