Abstract
Can add filler formula oil blanket. Not wear -resisting, short -lived, the elasticity that can solve the existing equipment existence do not lead to the problem that the leakproofness is low well. Include the round ring ontology who matches with the output shaft, open in circle ring ontology's inside wall middle section has round ring groove, is equipped with the packing in the circle ring groove, and the packing is outer distolateral inside circle ring groove, the distolateral circle ring groove outside that is in in the packing. Simple structure makes with low costs, simple structure, operation and convenient to use and practicality strong.
Description
Technical field
The utility model belongs to sealing device field, it relates to a kind of oil field sealing equipment, specifically can filled formula oil sealing.
Background technology
Tradition rod-pumped well reduction box or the oil sealing at output shaft of gear-box place, employing be mostly rubber, and rubber oil sealing is not wear-resisting, work-ing life is short, it is necessary to often change, and reduces working efficiency, having part to adopt packing, although improve rub proofness, but the not good sealing property of its elasticity is not high yet.
Summary of the invention
In order to solve not wear-resisting, the life-span is short, elasticity does not cause stopping property low well problem that existing installation exists, the utility model proposes and a kind of be mainly used in rod-pumped well reduction box or the oil sealing at output shaft of gear-box place, its concrete technical scheme is as follows:
Can filled formula oil sealing, comprising the circular body mated with output shaft, the inner side-wall stage casing of described circular body has circle shape groove, is provided with packing in circle shape groove, side, packing outer end is in circle shape groove inside, and the inner side of packing is in outside circle shape groove.
Described packing is high water base packing.
Described circular outer body wall is evenly provided with some fixed orificess.
Described circle shape groove is made up of the V-groove wall of ring-type, has circular gap on V-groove wall with on the card end of described circular body both sides end face in the same way.
The beneficial effects of the utility model: wear-resistant make its long service life, good springiness effectively ensure that sealing effect; Structure simply makes that cost is low, structure is simple, operation and easy to use and practical.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the right side structure schematic diagram of Fig. 1.
In figure: the circular body of 1-, 2-circle shape groove, 3-packing, 4-V type cell wall, the circular gap of 5-.
Embodiment
For the ease of understanding, below in conjunction with Fig. 1 and Fig. 2, the utility model is further illustrated:
Embodiment 1: can filled formula oil sealing, comprise the circular body 1 mated with output shaft, the inner side-wall stage casing of described circular body 1 has circle shape groove 2, so that packing 3 can be added; Packing 3 it is provided with, so that improving wear resistance in circle shape groove 2; It is inner that side, packing 3 outer end is in circle shape groove 2, and the inner side of packing 3 is in outside circle shape groove 2.
Embodiment 2: further, in order to better improve elasticity and the stopping property of this product, described packing 3 is high water base packing.
Embodiment 3: further, in order to ensure the firm effect of this product, described circular body 1 outer side wall is evenly provided with some fixed orificess.
Embodiment 4: further, in order to effectively improve the sealing effect of this product, described circle shape groove 2 is made up of the V-groove wall 4 of ring-type, thus provide a mutability space for described packing 3, have circular gap 5 on V-groove wall 4 with on the card end of described circular body 1 both sides end face in the same way, thus ensure can better ensure sealing effect in the case of crushing.
Useful effect: structure simply makes that cost is low, structure is simple, operation and easy to use and practical; Effectively solve not wear-resisting, the life-span is short, elasticity does not cause stopping property low well problem that existing installation exists.
