Abstract
Be seal box of plunger pump extracting tool disclosed in the utility model, be particularly useful for the maintenance of oil-field flooding, polymer injector system plunger type water injection pump, the sealed letter tool special for dismounting used when being a kind of maintenance.This extracting tool comprises screw rod, fixed head and top board, and the periphery of fixed head centre bore is corresponding with the bolt hole of pump head arranges bolt fixing hole, to be arranged on by screw rod in fixed head and to hold out against on top board, being provided with rotating handles in the upper end of screw rod.This extracting tool volume is little, lightweight, easy to carry, and simple to operate, steadily quick, safe and reliable, result of use is remarkable.The sealed letter of plunger displacement pump can be disassembled reposefully during operation, not damage sealed letter, improve maintenance work efficiency, reduce labour intensity, rate when improve the operation of plunger displacement pump.
Description
Technical field
The utility model relates to the maintenance unit of plunger type water injection pump, particularly seal box of plunger pump extracting tool, is particularly useful for the maintenance of oil-field flooding, polymer injector system plunger type water injection pump, the sealed letter tool special for dismounting used when being a kind of maintenance.
Background technology
The plunger type water injection pump of extensive use in oil-field flooding, note polymerizing technology, because the plunger of plunger displacement pump moves reciprocatingly, needs to install the total paired column of sealed letter and fills in row sealing, for preventing the leakage of pumped (conveying) medium.But due to the long-time high-pressure work of plunger displacement pump, sealed letter subjects pressure and wearing and tearing, therefore, often dismounting is needed to carry out overhauling or changing aborning.The method for dismounting of current employing is first unloaded by the platen bolt outside sealed letter assembly, is then fixed on rotation in bolt hole with jackscrew, platen is separated with pump head, then sealed letter and platen are unloaded.Position residing for sealed letter is special and due to impacts such as corrosion in water foulings, cause sealed letter and close adhesion between platen and pump head, very difficult during dismounting, wastes time and energy, inefficiency.In order to solve this difficult problem, maintenance sites needs seal box of plunger pump extracting tool.
Summary of the invention
The purpose of this utility model is to provide seal box of plunger pump extracting tool, can be disassembled by sealed letter stably, do not damage sealed letter from plunger displacement pump, improves dismantlement work efficiency, for convenience created by field maintenance plunger displacement pump.
The technical program can reach above-mentioned purpose: seal box of plunger pump extracting tool comprises screw rod, fixed head and top board, the periphery of fixed head centre bore is corresponding with the bolt hole of pump head arranges bolt fixing hole, screw rod to be arranged in fixed head and to hold out against on top board, being provided with rotating handles in the upper end of screw rod.
Compared with prior art the beneficial effects of the utility model are:
1, this extracting tool volume is little, lightweight, easy to carry, and simple to operate, steadily quick, safe and reliable, result of use is remarkable.
2, the sealed letter of plunger displacement pump can be disassembled reposefully during operation, not damage sealed letter, improve maintenance work efficiency, reduce labour intensity, rate when improve the operation of plunger displacement pump.
Accompanying drawing explanation
Fig. 1 is the structural representation of this instrument.
Fig. 2 is the structural representation of fixed head.
Fig. 3 be this extracting tool install and use schematic diagram.
Detailed description of the invention
Below in conjunction with accompanying drawing, this instrument is described in further detail: see Fig. 1 and Fig. 2, seal box of plunger pump extracting tool comprises screw rod 3, fixed head 2 and top board 4, the periphery of fixed head 2 centre bore is corresponding with the bolt hole of pump head 5 arranges bolt fixing hole, screw rod 3 to be arranged in fixed head 2 and to hold out against on the top plate 4, being provided with rotating handles 1 in the upper end of screw rod 3.In order to alleviate the weight of instrument, the peripheral structure of fixed head 2 is arc-shaped triangles.The lower end of screw rod 3 is that arc-shaped structure contacts with top board 4.The top cylindrical of top board 4 is provided with step, and this step coordinates with the lower end inner circle of sealed letter 7; The height of top board 4 conforms to the gap between sealed letter pressure cap 8 and sealed letter 7.
Concrete use procedure: as shown in Figure 3, first unloads sealed letter assembly from pump, the set bolt of platen 6 and sealed letter pressure cap 8 is unloaded, is installed between sealed letter 7 and sealed letter pressure cap 8 by top board 4, reinstall sealed letter pressure cap 8.Fixed head 2 and pump head 5 to be bolted and fastening.Drive screw rod 3 to rotate by rotating handles 1, screw rod 3 matches with top board 4, utilizes the thrust of screw rod 3, sealed letter 7 and platen 6 is released from pump head 5 reposefully, completes the unloading process of sealed letter assembly.
