Abstract
The utility model discloses a hosepipe following deflection-regulation polish rod sealer which comprises an upper packing box and a lower packing box which are installed on a polish rod; an upper hosepipe flange and a lower hosepipe flange are installed at intervals on the polish rod between the upper packing box and the lower packing box; the upper hosepipe flange and the lower hosepipe flange are connected through a stainless steel hosepipe; oil cotton sleeves are matched and sleeved on the upper hosepipe flange, the lower hosepipe flange and the polish rod in the stainless steel hosepipe; a support corrugated pipe or a spring skeleton is matched and sleeved on the outer wall of the oil cotton sleeve in the stainless steel hosepipe; and two hosepipe protection covers are installed at the exterior of the stainless steel hosepipe. The hosepipe following deflection-regulation polish rod sealer provided by the utility model is simple in structure, is convenient to operate, and can be used for thoroughly solving the problem of defection abrasion of the polish rod.
Description
Technical field
The utility model belongs to oil pumper well head water-tight equipment, relates to the improvement, particularly flexible pipe servo-actuated tuningout polished rod sealer of anti-eccentric wear packing box structure.
Background technology
OrderEmployed polished rod sealer in recovering the oil in preceding oil field; In the oil pumper running, can not adapt to because oil pumper is made the polished rod axis of multiple factor affecting generation such as alignment error and pit shaft inclination and the well head offset problem that the skew of sealer body axis causes, cause sealing ring eccentric wear, crude oil leakage; The polished rod wearing and tearing; Shorten maintenance period, increase cost.
Summary of the invention
The purpose of the utility model is to provide a kind of flexible pipe servo-actuated tuningout polished rod sealer, and it is simple in structure, and is easy to operate, can thoroughly solve polished rod eccentric wear problem.
The purpose of the utility model is achieved in that a kind of flexible pipe servo-actuated tuningout polished rod sealer; Comprise the packing box up and down that is installed on the polished rod; On the polished rod between the packing box bottom hose flange is being installed at interval up and down; Link to each other through stainless steel flexible hose between the last bottom hose flange; Cooperate suit oily cotton-padded covering on the polished rod in last bottom hose flange and the stainless steel flexible hose, cooperate suit support bellows or spring skeleton on the oily cotton-padded covering outer wall in the stainless steel flexible hose, two lobe flexible pipe protective covers are installed outside stainless steel flexible hose.
The utility model has changed the fault of construction of the hard sealing of oil pumping polish rod employing in the past tuningout, and result of use is following: 1, can guarantee that packing box is tentatively set upright and sealed down; 2, flexible pipe is swung with polished rod, avoids the packing box eccentric wear; 3, last packing box Follow-up seal can thoroughly solve polished rod eccentric wear problem; 4, simple in structure, make easily, reduce material consumption; 5, avoided setting upright firmly the frictional force of structure, the life-span is long.
Description of drawings
To combine accompanying drawing that the utility model is done further detailed explanation below.
Fig. 1 is the main TV structure sketch map of the utility model.
The specific embodiment
A kind of flexible pipe servo-actuated tuningout polished rod sealer; As shown in Figure 1; Comprise the last packing box and the following packing box 6 that are installed on the polished rod, at interval bottom hose flange 1 is being installed on the polished rod between the upper and lower packing box, link to each other through stainless steel flexible hose 5 between the last bottom hose flange 1; Stainless steel flexible hose 5 length are 100 ~ 300mm, and internal diameter is φ 25 ~ φ 60mm.Cooperate suit oily cotton-padded covering 3 on the polished rod in last bottom hose flange and the stainless steel flexible hose, oily cotton-padded covering 3 plays waterproof, and is antifreeze, the auxiliary seal effect of lubricated polished rod.Cooperate suit support bellows 4 or spring skeleton on oily cotton-padded covering 3 outer walls in the stainless steel flexible hose, two lobe flexible pipe protective covers 2 are installed outside stainless steel flexible hose 5,, prevent that fatigue damage from appearring in flexible pipe in order to compress stainless steel flexible hose 5.The utility model is simple in structure, and is easy to operate, can thoroughly solve polished rod eccentric wear problem.
