Summary of the invention
Problem to be solved in the utility model is: propose a kind of pump combination seal quick and easy for installation, this combination seal can both accurately be located in any angle, oiling.
The technical solution of the utility model is: a kind of 360 degree rotary pump combination seals, comprise shell, and be provided with pressing plate at the afterbody of shell, pressing plate is provided with positioning device; Described enclosure is a hollow, constitutes cylindrical cavity; Be provided with the tubulose seal in cylindrical cavity, the external diameter of seal is identical with the cylindrical cavity internal diameter; The inwall of seal is provided with annular protrusion; Be provided with oilhole between per two annular protrusions, be provided with oil groove between the oilhole; The outer wall of described shell is provided with the O RunddichtringO, and the afterbody inboard of described shell is provided with the outside thread gland, and the internal diameter of outside thread gland is not less than the internal diameter of annular protrusion; Shell can rotate with respect to pressing plate, and the positioning device on the described pressing plate comprises gland bolt and axially locating screw, and gland bolt is used for fixing pressing plate, and the axially locating screw is used for fixing the relative position between shell and the pressing plate.
As a kind of improvement project of the present utility model, described seal has a plurality of, and is separate between the seal, and along the axially-aligned of shell, so not only good sealing effect but also reduced the cost of making.
As a kind of improvement project of the present utility model, described shell afterbody also is provided with a grease trough, and the outside of grease trough is provided with O-ring seals, adjusts on the gland and also is provided with a pump nozzle, pump nozzle can communicate with grease trough, can make the pump nozzle can both oiling in any angle like this.
As a kind of improvement project of the present utility model, described shell afterbody also is provided with an axially locating groove, embeds in the axially locating groove during axially locating screw location, so as required set casing and the relative position of adjusting gland.
As a kind of improvement project of the present utility model, described annular protrusion is a rubber material, and the joint of annular protrusion and black box inwall meets at right angles, and the longitudinal section of each annular protrusion all becomes hook-type, and the sealing effect of this annular protrusion is better.
As a kind of improvement project of the present utility model, also be provided with the multiple tracks trim ring between described shell and the seal, the number of trim ring is identical with the number of annular protrusion, and this is because annular protrusion adopts rubber material, and therefore material softer has more originally added trim ring.
As a kind of improvement project of the present utility model, the inwall of described outside thread gland is provided with O-ring seals, also is provided with packing ring between outside thread gland and the seal.
