Chamber.Oilhole on mandrel is connected to the oil suction chamber of housing and oil back chamber respectively.In the high-speed rotation of mandrel, hydraulic oil is just
Each executive component of fixture is transmitted to by separator.But separator encounters when increasing a DFF Direct Fuel Feed road, needs to increase again
Add a pipeline, increase economic cost, and is not succinct enough in industrial design.
Utility model content
The purpose of this utility model is to provide a kind of hollow rotating separator, the technical issues of solution, is: cannot be compatible with
Subsidiary conduit is easy to cause pipeline chaotic.
In order to achieve the above objectives, using following technical scheme.
A kind of hollow rotating separator, including mandrel and covering the housing on the outside of mandrel, the housing is fixed, and mandrel can be
Do high speed rotary motion in the housing, it is described it is outer put on equipped with oil inlet passage and drainback passage, be equipped with first in housing inner hole
Annular groove and the second annular groove, first annular slot and the second annular groove are respectively oil suction chamber and oil back chamber, oil inlet passage and oil return
Channel is respectively communicated with oil suction chamber and oil back chamber, and mandrel, which is equipped with, is parallel to its axial fuel feed hole and oil return hole, the fuel feed hole
Be connected to respectively with the oil suction chamber of housing and oil back chamber with oil return hole, be equipped at the axle center of the mandrel along its axially through it is logical
Hole.
There is positioning shaft shoulder on the mandrel, the positioning shaft shoulder is in contact with an end face of housing, outside positioning shaft shoulder
Side is equipped with sealing cover.Positioning shaft shoulder makes the easier for installation and secured of mandrel and housing.
The other end of the housing is equipped with end cap, and the center of the end cap is equipped with opening corresponding with the through-hole of mandrel.
The end cap is equipped with bearing, and the inner ring of the bearing is fixedly connected with mandrel, the outer ring of bearing while and housing
It is fixedly connected with end cap.
It is equipped with through-hole among mandrel, the subsidiary conduits such as oil pipe, tracheae, water pipe can be passed through.While satisfaction point oil, increase
Add through-hole that can extend there through the pipeline that corresponding diameter needs, meets specific design requirement.
