main sealing Screw DC oil pump HSND280-46 is a side-in and side-out vertically installed oil pump. It is sealed by a skeleton oil seal. It is mainly configured in the seal oil system. Appropriate pressure enters the generator sealing tile, where the return oil on the empty side enters the air release tank, and the return oil on the hydrogen side enters the seal oil return tank and then flows into the float oil tank, and then flows into the air release tank depending on the pressure difference. The unit is generally equipped with one working and another standby, both driven by AC motors.

 

Before starting the main sealing Screw DC oil pump HSND280-46 after long-term storage, the elastic deformation of all elastic components (O-rings and shaft seals) must be checked. If they are aging, they must be replaced before being put into use.
