One-way reflux type dextral SR, sinistral DL
In the lip of the air measurement with an Angle of inclined tendons, using the principle of fluid mechanics, one-way pump suction, with reflux effect.
It is related to the rotation direction of the shaft. Due to the reflux effect, the radial force is smaller than the ordinary oil seal, which reduces the wear and heat generation and improves the service life. It is suitable for the occasions where the medium pressure is less than 0.05mpa and the rotational speed is ≤20m/s [3].
