What Is an Air Breather?
An air breather is a hydraulic device installed on top of a reservoir tank, hydraulic oil tank, or other oil-filled tank to vent the air inside to maintain a constant internal pressure and to prevent dust from entering the tank.
Caps are made of alloys, resins, or other materials with excellent durability.
They are removable with screws and often have a simple structure for easy maintenance.
Uses of Air Breathers
Air breathers are installed on top of reservoir tanks, hydraulic oil tanks, and other oil-filled tanks.
The amount of hydraulic fluid in the tank is constantly changing as the hydraulic fluid is used in the machine and the tank is refueled, and at the same time the air inside the tank is sucked in and out.
In this series of movements, the air breathers first remove dust and other foreign matter from the air during air intake to prevent them from entering the inside of the tank.
Also, by maintaining the pressure inside the tank at a constant level, the air breathers prevent deformation of the tank itself and damage to peripheral equipment, such as pumps due to changes in the pressure inside the tank.
Thus, air breathers are widely used in conjunction with tanks and other hydraulic equipment used in machine tools and ships.
Principle of Air Breathers
Air breathers are installed on top of hydraulic oil tanks and reservoir tanks to filter air that enters the tank as the oil level rises and falls inside the tank.
It is also used as an oil supply port for hydraulic oil and other oils.
If the element or cap of the air breathers becomes dirty and clogged due to continued use without cleaning, air cannot flow in and out of the tank smoothly and without interruption, causing abnormal pressure inside the tank and possibly damaging the hydraulic oil tank or reservoir tank itself due to the abnormal pressure. The pressure inside the tank may become abnormal, and the hydraulic oil tank or reservoir tank itself may be damaged by the abnormal pressure.
This is because the same phenomenon that occurs when a PET bottle is sealed and the air inside is drained out will eventually cause the PET bottle itself to collapse, as well as the hydraulic oil tank or reservoir tank itself and the hydraulic hoses connected to the tank.
If the tank is deformed in this way, not only will the tank itself crack, but oil leaks will also occur.
In addition, if the air breathers becomes clogged and the tank that holds the oil is unable to suck in air, when the amount of hydraulic oil changes, the pressure inside the tank becomes lower than atmospheric pressure, causing an excessive influx of air into the hydraulic oil and the formation of air bubbles.
If the air bubbles in the hydraulic fluid were to flow into the pump, cavitation would cause significant damage to the pump.
If the inside of the pump is damaged by the air bubbles, and iron powder or debris leaks out, it can cause malfunctions or damage to hydraulic equipment.
Thus, in order to maintain the filtration function of the air breathers as well as to prevent damage to the tank itself and the pump, it is necessary to perform maintenance such as periodic cleaning and periodic replacement of the air breathers element, cap, etc. The air breathers' elements and caps need to be cleaned and replaced regularly.
