The sudden non pressurization of the pneumatic air booster pump has troubled many users. Below, the editor will provide a detailed answer to this problem, hoping to help everyone.

1: When the air booster pump is started, it works normally. When it reaches the set pressure, it automatically stops working normally. If it is lower than the set pressure, it does not work. After unplugging the driving air source and reconnecting it, it works normally again. This situation is caused by the wear and swelling of the sealing ring of the directional valve, resulting in increased friction and insensitivity of the directional valve. The solution is to replace the sealing ring of the directional valve.

2: The air booster pump works rapidly back and forth, and the initial pressure is the same after boosting. This situation can be caused by two reasons: 1. The sealing ring of the reversing valve falls off or is damaged (replacing the sealing ring is sufficient). 2. There is something blocking the top pin of the air booster pump (cleaning up debris is sufficient).

3: The normal operation of the air booster pump can be caused by two reasons: 1) foreign objects entering the one-way valve, resulting in reduced sealing (cleaning the one-way valve is sufficient); 2) wear of the high-pressure sealing ring, resulting in disproportionate pressure (replacing the high-pressure sealing ring is sufficient).

4: The air booster pump does not work directly, which is due to the wear of the sealing ring of the directional valve (replacing the sealing ring of the directional valve).
