Abstract
The invention relates to a sealing system for sealing a drive head of a borehole pump relative to a borehole. The drive head consists of a drive and a casing. The sealing system is disposed on a base of the casing, wherein a polished rod extends through the sealing system. The sealing system is detachably connected to the base of the casing.
Description
Technical field
The present invention relates to a kind of sealing system, be used for making the driver of borehole pump to seal with respect to drilling well.
Background technology
American documentation literature US5,711,533 disclose a kind of sealing device, are used for having the oil pump device of the device of adjusting polished rod.The sealing device consists of two parts.These two parts couple together by flange.Be provided with static seal between flange, it seals flange relative to each other.The lower part of sealing device is provided with screw thread, and with the preventer of oil pump device, is connected.
American documentation literature US7,337,851 disclose a kind of driver element for oil pump device, and wherein, sealing unit directly is arranged on quill shaft below the polished rod clip.Two members are positioned at the top of hydraulic drive motor., by this layout, can dismantle driver and just can change the parts of sealing unit.
Canadian Patent document CA2515616C discloses a kind of sealing device, and wherein front and back have one after the other set gradually a plurality of joint rings, so that in the situation that the single joint ring that worn and torn can not produce leakage.Maintenance hole by this joint ring back of coming into force can be detected, and whether also has enough sealings, otherwise will activate in the additional encryption seal one.
, from many apparatus and method known in the state of the art, by them, the drive head of borehole pump is sealed with respect to drilling well.But, by by the known system of prior art, can't make sealing unit be adapted to other size and the size of polished rod.
Summary of the invention
Therefore the objective of the invention is, create a kind of sealing system, can be economical and the drive head of borehole pump is sealed with respect to drilling well by the sealing system, and the sealing system can be adapted to the different polished rod of diameter.
The sealing system of the feature of above-mentioned purpose by having claim 1 is achieved.Other favourable structural scheme is drawn by the feature of dependent claims.
The application discloses a kind of sealing system, and it makes the drive head of borehole pump seal with respect to drilling well.The drive head of this borehole pump consists of driver and so-called package assembly.This package assembly is arranged on the below of housing unit, and driver is hinged on this housing unit.This package assembly is by package assembly framework, dynamic sealing and be used for guiding the axle sleeve of polished rod to form.The external structure of this package assembly designs like this, make the power that occurs can from drilling well or in drilling well without the safety wind strategical vantage point by the flange connector transmission.The sealing system is arranged on the matrix of package assembly, and wherein for driving force being delivered to the borehole pump in drilling well, polished rod extends through sealing system.The sealing system removably is connected with the matrix of package assembly.
The sealing system is provided with Connection Element at downside, and sealing system removably is connected with the matrix of package assembly with force closure ground by this Connection Element type is sealed.In a preferred embodiment, this Connection Element is flange and/or screwed Connection Element.This screwed Connection Element for example refers to flange, and it is provided with screw thread on its outside, and this screw thread can be screwed in the matrix of package assembly.
Be provided with static potted component between the matrix of Connection Element and package assembly.This static potted component constitutes O-type circle or flat sealing ring in a preferred embodiment.In addition, the sealing system also has dynamic potted component.This dynamic potted component is gland or bearing ring seal spare.By the present invention, dynamic potted component refers to such element, namely by the parts of its salable activity, and the polished rod of rotation for example.Static potted component for example refers to O type circle or flat sealing ring, and they make not movable member, as sealing system and package assembly, mutually seal.
The internal diameter of dynamic potted component can be adjusted like this, makes the polished rod of various outer diameter to seal by sealing system.In another embodiment, whole sealing system consists of package assembly, and by the sealing system with other internal diameter, is replaced.By these modular makes, the polished rod of same salable various outer diameter.The advantage of two embodiment when making drive head is, always package assembly can arrange identical matrix, no matter the diameter of driver and polished rod is much.
Description of drawings
Below should at length set forth embodiments of the invention and advantage thereof by accompanying drawing.Each element mutual size in the accompanying drawings always is not equivalent to real size, because some shape is simplified, but other shape is in order to realize that better diagram is compared and enlarged with other element.
Fig. 1 shows by the position of sealing system of the present invention in drive head;
Fig. 2 there is shown by sealing system of the present invention at section.
The specific embodiment
Fig. 1 shows by the position of sealing system 20 of the present invention in the drive head 10 of conveying device.This drive head 10 consists of driver 16 and package assembly 22 basically, in this package assembly, other parts can be set.Driving-energy is delivered on polished rod 26 by driver 16.This polished rod 26 is connected with the borehole pump 12 that is arranged in drilling well 14.This borehole pump 12 is driven by polished rod 26.For drive head 10 is sealed with respect to drilling well 14, sealing system 20 is connected with the matrix 24 of package assembly 22.Structure and the function of sealing system 20 have been described more accurately in Fig. 2.
Fig. 2 there is shown by sealing system 20 of the present invention at section.Sealing system 20 is connected with the matrix 24 of package assembly 22 by Connection Element 32.In an illustrated embodiment, Connection Element 32 consists of flange connector, and wherein sealing system 20 removably is connected with matrix 24 by screw 28.In order to ensure can trickle between package assembly 22 and sealing system 20, sealing system 20 be provided with static potted component 34 on its downside 30, and this downside inserts in the matrix 24 of package assembly 22.Polished rod 26 seals with respect to the drilling well (not shown) by dynamic potted component 36.In a preferred embodiment, this dynamic potted component 36 is glands.Sealing system 20 is characterised in that, the sealing system can be complementary from different polished rod 26 and/or drilling well.This point realizes in the following manner, and namely the inner diameter, ID of dynamic potted component 36 and the outer diameter A D of polished rod 26 are complementary.But for pumped (conveying) medium is discharged once from sealing system 20 situation, it also is provided with outfall 18.
The present invention is described with reference to preferred embodiment.
