Abstract
The utility model discloses a filling material sealing device of a rotating shaft, which relates to a sealing device between a mechanical rotating shaft and a filling material box case of gas, liquid, solid-liquid mixed fluid, powder and particle solid media, and is generally applied to filling material sealing of screw shafts, stirring shafts, slurrying devices and the like. The filling material sealing device structurally comprises a press cover, the filling material box case, filling materials and a bottom ring, and is characterized in that a filling material ring, an oil storage ring, a filling material ring and an airflow sealing ring are sequentially arranged from one end of the press cover in a cavity formed by the pressing cover, the filling material box case, the bottom ring and the shaft surface of the rotating shaft, the filling material box case in the oil storage ring position is provided with an oil filling hole passage, and the filling material box case of the airflow sealing ring is provided with an air inlet hole passage. The filling material sealing device adds the airflow sealing ring in the filling material box case, the sealing ring is provided with an air inlet hole, airflows enter a cavity of the sealing ring through the air inlet hole, the air in the sealing cavity forms positive pressure, the airflows are blown out along the peripheral gap between the shafts and the sealing ring, and the relatively low-pressure sealing medium leakage passages are blocked. The sealing medium leakage passages are effectively blocked, and the sealing effect is ensured.
Description
Technical field
A kind of stuffing seal of running shaft, relate to the seal arrangement between a kind of stuffing box shell that is used for mechanical rotating shaft and gas, liquid, solid-liquid fluid-mixing and powder, granular solids medium, be applied to packing seals such as screw axis, stirring shaft, pulp device usually.
Background technique
In the chemical metallurgy production process, to use screw axis, stirring shaft, pulp device usually, its mechanical rotating shaft and gas, liquid, solid-liquid fluid-mixing and powder, granular solids medium require to have good sealing.At present, its seal arrangement can often adopt stuffing seal.
Packing seal is a kind of traditional gland seal, and filler is packed into after the stuffing box shell, through gland it is made axial compression, and when axle and filler had relative movement, the axial force of generation made filler generation plastic deformation, makes it closely to contact with stuffing box shell inwall with axle.Meanwhile, the oiling agent that floods in the filler is extruded, and forms oil film between surface of contact.Owing to exist micro-gap between axle and the packing surface of contact, the oil film that forms presents uneven contact condition, " boundary lubrication " state just appears in the contact position, and the recess of contact does not form little oil groove, thicker oil film is arranged, irregular labyrinth is formed with the non-contact position in the contact position, medium during this time in the crack repeatedly by throttling, play and stop liquid to flow leakage effect.Shortcoming is a poor sealing performance.
After stuffing seal uses a period of time at present, because regular extruding filler, make the oiling agent exhaustion of dipping, produce insufficient lubrication, cause between filler and the axle dry friction to occur, the gap that causes axle to occur between heavy wear, filler and the rotating shaft increases, and medium leaks out from the gap location direct-axis, the medium that flows out enters in the spiral Partner bearing support, causes damage of bearings.
Summary of the invention
The purpose of this utility model is at the deficiencies in the prior art part, and a kind of effectively plug for seal dielectric leakage passage is provided, and guarantees the stuffing seal of the running shaft of sealing effect.
The purpose of this utility model is achieved through the following technical solutions.
A kind of stuffing seal of running shaft, the structure of its device comprise gland, stuffing box shell, filler, base ring; It is characterized in that in the cavity that gland, stuffing box shell, base ring and running shaft axial plane form rising and be provided with packing ring, oil storage ring, packing ring, air current sealed ring successively by gland one end; Stuffing box shell at the oil storage ring position has the oiling duct, has the air inlet duct on the stuffing box shell at air current sealed ring place and air-flow seal ring.
The stuffing seal of a kind of running shaft of the present utility model is characterized in that being provided with sealed cap on described oiling duct.
The stuffing seal of a kind of running shaft of the present utility model is characterized in that being provided with suction tude on described air inlet duct.
The stuffing seal of a kind of running shaft of the present utility model is characterized in that the inlet hole that is provided with is along circumferential 3 uniform inlet holes on stuffing box shell and the air-flow seal ring on described air inlet duct.
The stuffing seal of a kind of running shaft of the present utility model, in the stuffing box shell, install air current sealed ring additional, seal ring has inlet hole, air communication is crossed in the cavity that inlet hole enters seal ring, because the gap between seal ring and the axle is very little, the sealing intracavity gas forms malleation, and air-flow blows out along the circumferential clearance between axle and the seal ring, has blocked the sealing medium leakage way of relatively low pressure.Effectively plug for seal dielectric leakage passage has guaranteed sealing effect.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
A kind of stuffing seal of running shaft, the structure of its device comprise gland 1, stuffing box shell 2, base ring 4; In the cavity that gland, stuffing box shell, base ring and running shaft 9 axial planes form, rise and be provided with packing ring 3, oil storage ring 5, packing ring 3, air current sealed ring 6 successively by gland one end; Stuffing box shell at the oil storage ring position has the oiling duct, has the air inlet duct on the stuffing box shell at air current sealed ring place and air-flow seal ring; On described oiling duct, be provided with sealed cap 8; On described air inlet duct, be provided with suction tude 7; The inlet hole that is provided with on described air inlet duct is along circumferential 3 uniform inlet holes on stuffing box shell and the air-flow seal ring.
During operation, increase original stuffing box shell length, the stuffing box shell increases oil-filling device, keeps filler and axle lubricated good, avoids axle and filler dry friction.In the stuffing box shell, install air current sealed ring additional, seal ring has 3 inlet holes, connect pressurized gas, compressed air stream enters in the cavity of seal ring by 3 inlet holes, the sealing intracavity gas forms malleation, air-flow blows out along the circumferential clearance between axle and the seal ring, has blocked the sealing medium leakage way of relatively low pressure.To guarantee sealing effect.
