What is the principle behind refilling this type of oil cup?
Can you see the connection tube at the bottom of the oil cup that extends into the device? When the lubricating oil level in the equipment drops below that level, the oil reservoir automatically refills it.
The principle behind water supply to chickens in a chicken farm, or the principle by which a humidifier adds water to the misting nozzle, is the principle of a communicating vessel.
It’s a bit more refined than what we usually use
Function of the level control oil cup: To maintain a constant level of lubricating oil inside the bearing housing. Principle and structure of the level control oil cup: The position of the inclined surface is crucial for this device; the working oil level determined by it represents the oil level under normal operating conditions. Some constant-level oil cups do not have dedicated air vents, but it is still necessary to ensure that the area above the inclined surface is in free communication with the atmosphere.
It’s just a U-shaped tube; although some fuel tanks use negative pressure, the installation still requires consideration of the height of the fuel level gauge and the slope of the fuel refilling pipe~~
