How does air get into the oil cup?

2020-04-03View Original

Thread Content

There is negative pressure above the oil cup, p1 p2 = atmospheric pressure on the oil surface in the bearing box, then the oil level in the bearing box drops, the liquid level at the base of the oil cup drops, and the atmosphere enters through the pores of the oil cup, but it is also 1 atmosphere. Why does the oil in the oil cup drop back and refill the fluid?

Will the atmosphere pass through the oil in the oil cup? melt in oil

The principle of the connector, as long as the oil seals the slope of the oil cup, there will be no air intake

The function of the air hole is that after the slope of the oil cup is exposed, air enters the oil cup through the air hole, causing the oil in the oil cup to flow to the bearing box.

The oil cup is full of oil. How can the air get in? Isn't it blocked?
