High pressure two-way inflator will be easier and safer. The principle is the same. Generally, high-pressure pump means that the air cylinder wall, piston, etc. can withstand greater pressure to inject high pressure into the expanded object.

The difference between high and low pressure two-way inflators is the diameter of the inflator. The barrel diameter is small, the gas pressure is high (the same handle thrust), and the amount of gas compression is small each time, but it can reduce the pain.

High pressure two-way inflator: In a broad sense, the inflator connected to the air chamber is called the high pressure inflator. Working principle: The air compressed downward by the air cylinder enters the air chamber first. The air chamber is installed with an air resistance valve, which stores the gas entering the air chamber to form a high pressure. One end of the air belt is connected to the high-pressure air chamber, and the other end is connected to the tire. After secondary compression, it takes a lot of effort to inject air into future generations.

The high-pressure pump in the agreement can pump air at a pressure of more than 30 kg, which is called the high-pressure air cylinder. It is specially used to refuel professional equipment such as air guns for shooting.

Select according to personal requirements

When choosing the inflator, you should consider your own needs and choose it according to your own direction of use, rather than light, small and invigorating. Because motorcyclists need high tire pressure, they should pay attention to the tire pressure that the coal inflator can obtain when purchasing. From the point of view of ordinary pumps, even if the product can hit the tire pressure required by road vehicles, it is also necessary to consider whether the strength is enough to cope with it. After all, it is not easy to use the power of PUMP in your hand, especially for female riders.

In addition, road vehicles need more accurate tire pressure, so it may be more appropriate to choose a handheld device with a tire pressure gauge. It will be easier if you can step on your feet, but the weight will be heavier. If the economic situation allows, the high-pressure gas cylinder will be the choice for road car friends to pursue lightweight. My friends on the mountain bike don't have problems with high tire pressure or correct tire pressure, so it's good to carry a convenient coal inflator.

Precautions when purchasing bicycle air pump

What details should I pay attention to when buying an air pump? The air ports of ordinary bicycles are divided into American air ports and French air ports. Therefore, most of the inflators on the market are made of "mouth" or head and dual purpose mouth that are applicable to both types of air nozzles. If the inflator has only American mouth, car friends will say American. Most of the pipes of the coal pump are plastic and aluminum alloy. Although the pump of the plastic pipe is light and cheap, it is easy to deform with high temperature caused by friction. Aluminum alloy is still the mainstream of the current market.

Whether it is a smart mouth or a traditional air vent, it will also break down after a long time of use. Whether the pump is played well or not, the holding also plays an important role. In particular, pay special attention to ergonomics.
