Why does the air in the small air pump storage tank disappear quickly?

The reasons why the air pump does not inflate include the softening of the built-in spring plate preventing it from rebounding and pipeline blockage. Below is a detailed explanation of the causes and solutions to this problem: Softening of the built-in spring plate: The spring plate inside the air pump will gradually soften with use. When the pressure in the air storage tank reaches 4 atmospheres, the softened spring plate cannot rebound due to the back pressure from the storage tank, making it impossible to continue inflation. In this case, a new spring plate needs to be replaced. Pipeline blockage: If the air outlet pipeline of the air pump is blocked, the air pump will be in a state of high internal pressure and unable to inflate. The solution is to remove the pipeline and replace it with a new one.

I also have a small air pump at home. After several years of use, the air in the tank leaks out quickly. I think the main reason is the aging of the sealing ring. Rubber seals harden and crack over time, especially near the joints and valves, making them prone to leaks under high pressure. Loose connections or dust blockages can also cause air to escape. I tried applying some soapy water to potential leak points, and bubbles helped locate the problem. Regular maintenance is crucial, such as releasing excess air after each use to prevent water accumulation and corrosion inside the tank, and cleaning the connection areas. If the problem is severe, it’s necessary to buy a new seal and replace it. For car tire inflation, rapid air loss means insufficient pressure, leading to underinflated tires that affect balance and driving safety. Regular checks are more convenient than emergency repairs.

The common causes of air leakage in a small air pump's air tank are usually due to aging or damaged components. Worn-out seals are the most frequent issue, as rubber loses elasticity over time, leading to loose connections and air leaks. Valves, such as safety valves not being tightly closed or springs failing, can also result in air loss. Loose fittings can be fixed by tightening them, but if the tank body has rusted small holes, it needs to be replaced. The inspection method is simple: spray soapy water on suspected areas, and bubbles indicate a leak. When used for inflating car tires, a leaking pump can lead to inaccurate inflation, potentially causing uneven tire pressure and increasing the risk of a blowout. It is recommended to check the pump's seals every few months, store it in a dry place to avoid corrosion, and extend its lifespan. Preventing problems is always better than dealing with them afterward.

My small air pump can't hold air, it leaks out in just a few minutes. This is usually a sealing issue, where the rubber ring hardens and causes loose connections that leak air. It can also happen if the valve isn't closed tightly. When checking, listen for any hissing sounds and spray some soapy water to locate the leak. The solution isn't complicated—just replace the sealing ring or tighten the connections. In terms of car tire inflation, insufficient air pressure affects the accuracy of tire pressure and makes driving unstable. Remember to release the air after use to prevent internal moisture buildup. Timely repairs can avoid bigger problems.
