How to Read the Gauge on a Car Air Pump?
2 Answers
When inflating, simply look at the numbers on the pressure gauge. Below is relevant information about car air pumps: 1. Introduction: A car air pump, also known as an inflator or air compressor, operates by the rotation of an internal motor. The working principle is that when the motor runs to pump air, the valve of the connecting pipe is pushed open by atmospheric pressure, allowing air to enter the cylinder. When inflating the tire, the valve is closed by the pressure inside the cylinder, directing the air into the tire. 2. Product Features: Equipped with a direct-drive powerful motor, it operates without gear friction noise, completing inflation in a short time. The steel-built machine offers ultra-strong pressure and durability, ensuring continuous inflation. It features a stainless steel airtight valve for high-quality air output and comes with a complete set of inflation nozzles, suitable for tires, rubber boats, air mattresses, sports balls, and other various inflation purposes.
As a new driver, I felt a bit confused when using a car tire inflator for the first time, but it's actually quite simple. The inflator has a pressure gauge on its surface, usually measured in PSI or BAR. My car's recommended tire pressure is indicated on the label inside the driver's door frame, for example, 32 PSI. To use it, first park the car securely, then screw the inflator nozzle tightly onto the tire valve to ensure no air leaks. Connect the power source (usually the cigarette lighter socket), press the start button, and the inflator will begin working—the needle on the pressure gauge will move or the digital display will change. Once it stabilizes, the number shown on the gauge is the current tire pressure. If it's below the recommended value, keep inflating until it reaches the proper level; if it's too high, use the deflation button on the pump to release some air. Remember not to overinflate, as this can cause the tire to burst. It's best to check the tire pressure when the tires are cold for more accurate readings. Maintaining the correct tire pressure while driving daily helps save fuel and prolongs tire life. I check mine once a month to avoid any issues.
