How much oil is suitable for a small air pump?
2 Answers
It is suitable to add 0.6L of oil to a small air pump. Introduction to car air pumps: Car air pumps, also known as inflators or air compressors, operate through the functioning of an internal motor. The principle involves the motor's operation: during suction, the valve of the connecting pipe is pushed open by atmospheric pressure, allowing air to enter the cylinder. When pumping air into the tire, the valve is closed by the pressure inside the cylinder, directing the air into the tire. This process essentially utilizes atmospheric pressure to inflate cars, balls, and rubber boats. Applicable vehicle types for air pumps: These portable car air pumps are generally only suitable for small cars. They are not recommended for large buses or trucks to avoid insufficient pressure, which could lead to hazards.
I've been using a small air pump for over a decade, and adding oil requires experience. Generally, the oil level window is on the side of the pump, and filling it halfway is sufficient. Never fill it to the maximum, otherwise, oil will splash everywhere during operation, making cleanup difficult and wasting resources. Specialized oil types should be used, such as SAE30 viscosity, which is most suitable. Regular car oil is too thin and can easily fail, damaging the motor. Regular checks are crucial. In summer, due to high temperatures, you can fill it up to two-thirds of the height, while in winter, maintain it at half to prevent condensation and starting difficulties. After each use, clean the dust around the oil window to avoid misjudgment. This can extend the lifespan by three to five years without issue. Don’t overlook this small step to avoid repairing major components later.
