Automobile tire air pumps, also called inflators, air pumps, and vehicle-mounted air pumps, work through the operation of internal motors. When pumping air, the valve of the communicating device is opened by atmospheric pressure, and the gas enters the cylinder. When pumping air into the tire, the valve is closed by the air pressure in the cylinder, and the gas enters the tire. It can be regarded as using the principle of atmospheric pressure. It is the same as inflating cars, rubber balls and rubber boats.
R & D background
Accidents caused by uneven tire pressure occur from time to time. It can be seen that keeping the tire pressure in the driving at any time should not be underestimated. When driving at high speed, puncture occurs mainly due to low tire pressure and high tire pressure.
With the continuous increase of domestic cars and the shortage of oil resources, oil prices have been rising all the way, reducing fuel consumption has become the most important issue for every car friend. Tire pressure is very particular, low or high pressure will increase fuel consumption and reduce tire service life. Therefore, having an air pump with "high accuracy and fast inflation" during driving will save you more effort, worry and money.
Power access method
Car tire inflation pump is an electrical appliance that uses on-board power to inflate tires. The input power supply is 12V-15A. There are generally two access methods,
1. Cigarette lighter access
This type of access method is suitable for single-cylinder air pumps and for vehicles with small displacement, because the power is more suitable and convenient.
2. Battery access
This type of dual-cylinder in-vehicle air pump is suitable for high-power vehicles, such as small trucks, passenger cars, off-road vehicles and other high-capacity large-displacement vehicles. Need to connect the power converter to the battery to use.
