What is the basis for installing breather valves on the oil tanks of reducers or moving equipment? What power rating should be used for the vent valve, or which standard should be referred to? Please ask
The fuel tank is usually under negative pressure or at atmospheric pressure, which facilitates oil return; in simple terms, the breather valve prevents positive pressure from building up inside the fuel tank
Both oil and gas evaporation as well as bubbles returning to the oil tank can cause positive pressure in the tank; negative pressure facilitates oil return, and the pressure on the oil seal also decreases
To prevent the lubricant from expanding due to increased temperature, which could create positive pressure and damage the oil seal
Why is a vent valve needed? Is it for outdoor installation or in a relatively harsh operating environment? If there are no such reasons, it shouldn’t be necessary, right?
