The working principle of an oxygen pump is to extract oxygen from a storage container through mechanical or chemical forces and transport it to the target medium through pipelines. Specifically, there are several different ways to achieve this process:
Compressed air or liquid drive: Compressed air or liquid enters the pneumatic device inside the pump body through the supply pipeline, driving the movement of one or more pneumatic pistons. The piston moves back and forth under the action of aerodynamic force, thereby driving the suction and discharge of oxygen. When the piston moves towards the oxygen storage atmospheric cylinder, gas enters the extraction chamber, and oxygen enters and fills the extraction chamber through the intake valve; When the piston moves towards the exhaust chamber, the gas pressure in the exhaust chamber increases, and the airflow is discharged from the pump body through the exhaust valve and sent to the target medium through the delivery pipeline.
Chemical reaction produces oxygen: This pump mixes the chemical reaction liquid with the catalyst in the oxygen storage container, and after triggering the chemical reaction, produces a large amount of oxygen. Oxygen is injected into the target medium through a propulsion device.
The principle of the electromagnet of the fish tank oxygen pump: The fish tank oxygen pump is an electromagnet. When the electromagnetic iron coil is energized, the electromagnet generates magnetic force, which attracts the iron plate and drives the movement of the cup. At the same time, it also drives the normally closed contact to disconnect, causing the electromagnetic coil to lose power and the electromagnet to lose its magnetic field. The iron plate automatically bounces back to its original position under the action of the spring, and at the same time, the normally closed contact is closed, the coil is energized, and the electromagnet generates magnetic force and attracts the iron plate. This cycle continues to drive the movement of the cup, completing suction and exhaust. The discharged air is sent into the fish tank water through the pipeline, playing a role in increasing oxygen.
In addition, oxygen pumps are widely used in aquariums, pond aquaculture, sewage treatment, and medical fields. They transport oxygen from the air to the water through specific mechanical devices, increasing the dissolved oxygen content in the water and meeting the growth and survival needs of aquatic organisms.
