Description
Technical field
The utility model relates to polymer-injecting pump sealing technique used in tertiary oil production in oil field, specifically a kind of polymer-injecting pump
Adjustable type Jie's rod seal apparatus.
Background technique
Currently, the polymer-injecting pump that the poly- scene of note uses is reciprocating plunger pump, it is the key equipment for pumping polymeric media.
The polymer-injecting pump that three centers of adopting of lonely east use is largely the reciprocating plunger pump of Shengli Oil Field overall mechanical factory production.In daily production
In operational process, there are following three points in the main reason for causing polymer-injecting pump lubricating oil to waste, first is that when Jie's bar is injured or addition lubrication
When oil is excessive, Jie's bar concentricity is poor, there is Jie's bar oil seal failure, serious oil leakage phenomenon occur；Second is that when plunger wear is tight
Weight, packing occur thorn leakage, polymer mother liquor are caused to bring crankcase by Jie's bar, so that lubricating oil generation is rotten, viscosity is reduced,
Lubricant effect is poor, once tours of inspection not in time, be easy to cause crankcase temperature excessively high, tile kilning phenomenon occurs.Third is that when note is poly-
The bearing damage of pump, bearing clast enter lubricating oil, cause bearing bush abrasion, deterioration of lubricant, these factors all seriously affect
The normal production of polymer-injecting pump, wastes a large amount of lubricating oil.
The power end of polymer-injecting pump is box-structure, and power end is using splashing mode to the movements such as crankshaft, connecting rod, crosshead portion
Part friction pair is lubricated, and lower part is oil sump in cabinet.On the cabinet of polymer-injecting pump, motive position is by oil sealing at two
Sealing is realized, first is that Jie's bar enters crankcase position, second is that this is all by oil sealing at two with crankcase junction outside crankshaft
Realize sealing, lubricating oil is mainly to pass through to leak at oil sealing, it is main that this, which is the internal factor for influencing lubricating oil leakage,
Factor, when plunger damages, packing thorn leakage, mother liquor enters crankcase by Jie's bar, causes lubricating oil to whiten rotten, and viscosity reduces,
This is the external factor for influencing lubricating oil leakage.So as long as we have found the internal cause and external cause for influencing lubricating oil leakage,
The method for solving lubricating oil leakage can be found.
Summary of the invention
The purpose of this utility model designs a kind of polymer-injecting pump adjustable type Jie aiming at drawbacks described above of the existing technology
Rod seal apparatus.
The utility model is realized by following technical proposals:
The utility model includes: sealed letter, airtight and watertight padding, pressure cap, gland, Jie's bar；It is characterized in that: the polymer-injecting pump is adjusted
Airtight and watertight padding is equipped in the sealed letter of formula Jie's rod seal apparatus, pressure cap pushes down airtight and watertight padding, and gland is threadedly coupled with sealed letter, will
Airtight and watertight padding compresses, and Jie's bar passes through from the centre bore of sealed letter, airtight and watertight padding, pressure cap, gland, and bolt passes through consolidating on sealed letter
Determine hole, sealed letter is connect with polymer-injecting pump shell.
Sealed letter stepped cylinder described in the sealed letter cuts structure, and the right lower part lacks for flange, periphery horizontal symmetrical
If centre bore is stepped hole, and left side macropore is equipped with internal screw thread and pressure cap external screw thread cooperates, and lower part is equipped with " L " there are four fixation hole
Type oil return hole.
The airtight and watertight padding is lead powder oil immersion asbestos packing.
The pressure cap is step ladder circular ring structure, is equipped with centre bore, interior annular groove is equipped in centre bore, left end outer diameter is greater than the right side
Outer diameter is held, outer circle is equipped with outer annular groove, and interior annular groove and outer annular groove pass through cross-hole connection.
The gland is similarly step ladder circular ring structure, is equipped with centre bore, and left end outer diameter is less than right end outer diameter, and left end is equipped with outer
Screw thread and sealed letter screw-internal thread fit, left end outer circle are laid with six rectangle handling slots.
Working principle: by the fixed oil sealing of original polymer-injecting pump Jie's bar, it is changed to threaded adjusting gland, gland compresses sealing and fills out
Material, airtight and watertight padding generate radial deformation, and aperture becomes smaller, and uniform force, good heat dissipation effect, automatic compensation ability is strong, realize Jie's bar
Sealing, is adjusted at any time according to the wastage of lubricating oil, in addition, the arrangement achieves " zero load " sealing, pressure cap centre bore it is interior
Annular groove is by cross-hole and outer annular groove connection, and by lower return hole in sealed letter, the machine oil that Jie's bar is taken out of is again
Crankcase is flowed back into, " stifled ", " thin " combination is realized, oil sealing is made to work in the absence of stress, reaches ideal sealing effect
Fruit.
The beneficial effects of the utility model are: being suitable for the sealing of polymer-injecting pump Jie's bar used in tertiary oil production in oil field, structure
Simply, installation and repairing is convenient, and good reliability is cheap, and by the fixed oil sealing of polymer-injecting pump Jie's bar, it is close to be changed to threaded adjusting gland
Envelope, is conveniently replaceable airtight and watertight padding, reduces airtight and watertight padding replacement frequency, accomplishes cleaning, safety in production, reduces production cost, greatly
The leakage of amplitude reduction lubricating oil saves lubricating oil, reduces environmental pollution, mitigate the labor intensity of worker.
