Teach you to Understand Air Pressure Gauge in A Few Minutes

The air pressure gauge is a pneumatic tire pressure gauge. It consists of a head, a piston, a body, a ruler, a mainspring, etc. There is only one air pressure measurement port on the head. It is used for tire pressure measurement of small vehicles such as mini cars and motorcycles.

Instructions:

1. The angle between the centerline of the air pressure metering port and the axis of the meter body is 90°-180°, the ruler is a square, and the range scale value is 0.07Wpa-0.4Wpa. Gently tap the instrument case or watch glass with your fingers before taking a reading to remove friction in the drive mechanism.

2. When observing, the pointer overlaps with the mirror pointer. At this time, the index value of the pointer is the value of air pressure, and the reading is accurate to one decimal place. Read the temperature indicated on the barometer, accurate to one decimal place.

3. Align the notch on the measuring end of the air pressure gauge with the tire valve. At this time, the pointer of the tire pressure gauge is deflected, and the indicated value is the inflation pressure of the tire, or the benchmark of the tire pressure gauge is pushed out under the action of air pressure. At this time, the value displayed on the benchmark is the inflation pressure of the tire. The greater the pressure, the more the pointer will deviate.

Precautions:

Inner ring value: pounds per square inch

Outer ring value: kilogram force/square centimeter (engineering atmospheric pressure) = 1.033 standard atmospheric pressure = 1.02 bar

If it is a car tire, it is generally 2.0~2.5bar, not more than 3.5bar

If it is a light truck tire, it is generally 6-tier, 3.0~3.5; 8-tier 4.0-4.5bar, 10-tier no more than 5.5bar

If it is a trailer tire, generally no more than 4.2bar

The standard air pressure of the tire is marked on the driver's door or on the side of the door (in addition, this standard value can also be found on the fuel tank cap and the manual). It should be noted that there are different standard units for air pressure, generally, there are 3~4 kinds. Just like the weight that is useful in kilograms and kilograms, there are also 3 to 4 units of the indication on the barometer, such as kg/cm2, bar, PSI and kpa. The conversion relationship between them is as follows: 1bar=1.02kg /cm2=102kpa=14.5PSI. Look at the difference between the measured value and the standard value. If it is too high, let out some air. If it is too low, add air until the tire pressure matches the standard pressure.

Note that if you find that the vehicle needs to be filled with air, you can solve it on the spot with an inflator. If there is no car owner, you need to go to the nearest tire shop to inflate. The distance to the inflation point should not exceed 1.6km, because after the car is left standing for 4 hours, the tire pressure is still accurate within 1.6Km.

According to relevant information, the standard air pressure of ordinary car tires is 2.5kg for the front wheel and 2.7kg for the rear wheel in winter; 2.3kg for the front wheel and 2.5kg for the rear wheel in summer. This ensures safe driving and comfort while keeping fuel consumption to a minimum.

Anyone who has a car at home or who is going to buy a car must read this article carefully, because it can be used in daily life, understand the standard air pressure of your car, and often check the air pressure gauge of your car tires, to see if it meets the normal air pressure standard, so that improvements and adjustments can be made in real-time. For car tires, the air pressure gauge is an essential thing, so learning to read the air pressure gauge is also a must.
