Description
Technical field
The utility model relates to helical rotor pump, particularly the defeated helical rotor pump outlet sealing structure of a kind of high-pressure ground collection.
Background technique
The general outlet pressure of existing helical rotor pump is no more than 3MPa, the exit seal flange of helical rotor pump is provided with counterbore I, rubber seal I is provided with in counterbore I, again stator tube and this counterbore I are closely set with, helical rotor pump is also provided with threeway stator flange, threeway stator flange left side is provided with counterbore II, rubber seal II is provided with in counterbore II, again stator tube and counterbore II are closely set with, threeway stator flange and exit seal flange complete outlet sealing structure by installing draw lever locking, when helical rotor pump outlet pressure is more than 3MPa, rubber seal will lose seal action.
Summary of the invention
The utility model will solve the deficiency that existing helical rotor pump outlet sealing structure exists, and provides the high-pressure ground collection of a kind of anti-high pressure, good airproof performance defeated helical rotor pump outlet sealing structure.
Technical solution of the present utility model is:
The defeated helical rotor pump outlet sealing structure of a kind of high-pressure ground collection, comprise threeway stator flange, threeway stator flange left side is provided with counterbore, rubber seal is provided with in counterbore, in counterbore, stator tube is installed, on described threeway stator flange left side, circumference is evenly installed with four pull bars, its special way is: the intrinsic stator tube sealing flange of stator tube left end, described stator tube sealing flange left side is provided with the groove I of annular, exit seal flange is provided with on the left of described stator tube sealing flange, this exit seal flange right side is provided with the groove II of the annular corresponding with groove I, sealing steel rings is provided with between described groove I and groove II, described stator tube sealing flange and exit seal flange are provided with the through hole I corresponding respectively with pull bar and through hole II, and pull bar is through described through hole I and through hole II, and pull bar Outlet has been threaded connection nut, described stator tube sealing flange and exit seal flange right side are also respectively equipped with the equally distributed through hole III of corresponding circumference and tapped hole, the defeated helical rotor pump outlet sealing structure of this high-pressure ground collection is also provided with bolt, and described bolt passes through hole III and is threaded connection with tapped hole.
The beneficial effects of the utility model are: the seal form adopting sealing steel rings, groove, and by bolt and pull bar double locking, anti-pressure ability is higher, better tightness.
