Many people have the worship and yearning for nature, like to drive a long distance across the desert, snow and other soft ground, need to reduce tire pressure to increase adhesion; In the long-distance field, due to the limited spare tire, it is necessary to self-repair the tire, but these are inseparable from the car air pump. From the emergency rescue and enhance the passage, the vehicle air pump is essential.

These skills should be mastered when selecting an air pump! The inflation speed of the vehicle air pump is different, the low-power inflation is slow, and the high-power inflation is fast. If the car tires are large, it is recommended to use a high-power air pump, and the inflation speed is faster. The power cord of the car air pump must be long, otherwise when inflating the car tire, the air pump can not reach the tire can be embarrassing. The length of the power cord is best more than 2 meters, so as to meet the needs of the car 4 wheels inflation tire pressure on our daily driving safety has a great impact, low pressure not only tire wear, and fuel consumption increases sharply; It is very easy to burst a tire at high pressure. When the tire pressure is unstable or the tire is flat, it also has great damage to the car wheel hub and brake. Therefore, as a car lover, must have a comprehensive understanding of tire pressure, always grasp the tire pressure situation, it is necessary to carry an inflator pump. Especially long-distance drivers, we must always care about the tires of the car, and grasp the situation of tire pressure at any time, so that the tires are scrapped! Watch the power! The power of the air pump is determined according to the size of the car, so when choosing the car air pump, the small car can choose a single cylinder, enough to meet the daily inflation use; However, a slightly larger model needs to use a two-cylinder air pump, otherwise the inflation is slow and consumes electricity. Generally, the horizontal bar or parallel bar pump on the market can only be used as a supplement. If the new tire is punched once, Xiaobian still recommends that you go to the auto repair shop.

If the tires of the car have no air, it is really very troublesome, serious tire wear consumes the most fuel, and if the tires are seriously worn, there will often be skidding, fuel consumption will also increase, it is a very troubling thing, if the trunk is equipped with an air pump, then there is no such problem, this air pump 12V power supply, Compact and convenient, strong power, accurate tire pressure measurement, fast automatic filling stop, long life, is a necessary tire pump for self-driving, critical time emergency
Tire pressure gauge accuracy. In order to make the data more accurate and stable when inflating, the accuracy of the tire pressure gauge can not be ignored. In the past, the old tire pressure gauge used the mode of table separation, and the data accuracy is poor. At present, the tire pressure gauge of big brands uses the embedded integrated design, which can avoid the tire pressure gauge from crashing and loosening, resulting in inaccurate measurement data. Air pump connector. The joint is a common part of the pump, we should choose a pure copper joint pump, so that it is durable and safe, even if you accidentally step on it, it is okay, if it is ordinary iron it is easy to deform, so we should see it clearly. Double cylinder air pump: the parallel bar air pump is the use of a driving machine to drive the crankshaft for rotating movement, the crankshaft through the connecting rod to drive the piston for reciprocating movement, the reciprocating movement of the piston using the volume of the cylinder changes periodically: The intake and exhaust valve at the top of the cylinder is periodically opened and closed, and the air inhaled by the intake valve is compressed through the piston to reach the exhaust pressure through the exhaust valve, exhaust pipe and check valve into the gas storage tank for users to use. Generally suitable for large SUVs and other off-road vehicles, medium and large cars, fast inflation, small power consumption!
