air pump A device that removes air from an enclosed space or adds air from an enclosed space. Air pump is mainly divided into electric air pump and manual air pump, foot air pump. Electric air pump. An air pump powered by electricity compresses air continuously through electricity to produce air pressure. Mainly used in pneumatic gluing, car inflation and so on.
An air pump powered by electricity compresses air continuously through electricity to produce air pressure.
Application of electric air pump: pneumatic gluing, automobile inflation, etc.
The working principle of the air pump is: the motor drives the crankshaft of the air pump through two triangular belts, so as to drive the piston to pump, and the gas is introduced into the air reservoir through the guide pipe. On the other hand, the gas in the storage cylinder is introduced into the pressure regulating valve fixed on the air pump through a guide pipe, so as to control the air pressure in the storage cylinder. When the air pressure in the storage cylinder does not reach the pressure regulated by the pressure regulating valve, the gas entering the pressure regulating valve from the storage cylinder cannot open the pressure regulating valve valve; When the air pressure in the storage cylinder reaches the pressure regulated by the pressure regulating valve, the gas entering the pressure regulating valve from the storage cylinder opens the pressure regulating valve valve, enters the airway communicated with the pressure regulating valve in the air pump, and controls the air inlet of the pump to be normally open through the airway, so as to make the air pump run under empty load, achieve the purpose of reducing power loss and protecting the air pump. When the air pressure in the storage cylinder is lower than the pressure regulated by the pressure regulating valve due to loss, the valve in the pressure regulating valve is returned to the position by the return spring, and the control air path of the air pump is disconnected, and the air pump starts to pump again.
The air pump is powered by the foot force, which compresses the air constantly through the foot force to produce air pressure to work.
Application of foot air pump: bicycle pump, filling balloon or pneumatic small toys.
The air pump, powered by hand force, compresses air constantly through hand force to produce air pressure.
Application of manual air pump: filling balloon or filling pneumatic small toys.
