The oil field plunger pump packing box gland tripping prevention device disclosed by the utility model is reasonable in design, and due to the adoption of a special structure, high support force is provided for the plunger pump packing box gland; the plunger pump packing box gland is prevented from tripping or withdrawing, the security in production operation is improved, and daily maintenance in the production process is facilitated.
Description
Technical field
?the utility model relates to a kind of Machining Technology field, especially a kind of oil field plunger pump gland for packing box trip-proof device.
Background technology
?at present, the most of plunger displacement pump that adopts of oil field flood pattern is to oil-field flooding, to supplement stratum energy.Need to carry out re-injection in order to save water resource to a large amount of oilfield produced waste waters toward contact, but find in actual moving process, because oilfield sewage has very strong corrosivity, often cause the connecting filament buckle corrosion of packing box and gland, contact surface is reduced, bonding strength declines, and deviates from phenomenon thereby produce gland, affects production safety operation.
Utility model content
?the technical problems to be solved in the utility model is to provide a kind of oil field plunger pump gland for packing box trip-proof device reasonable in design, easy to use.
?for solving the problems of the technologies described above, technical solution adopted in the utility model is: a kind of oil field plunger pump gland for packing box trip-proof device, comprise end cap, be connected to the middle hollow cylinder on end cap right side, be threaded connection the supporting hollow cylinder of position adjustable on middle hollow cylinder, be arranged on left setscrew nut and the right setscrew nut at middle hollow cylinder two ends and be arranged near the stiffnut in supporting hollow cylinder upper surface, the described end cap back side is provided with the recessed circular hole corresponding with plunger pump grease seal end cap nut location, be provided with internal thread in middle hollow cylinder inside, on supporting hollow cylinder, be provided with the external screw thread corresponding with middle hollow cylinder internal thread.
?further, described end cap and middle hollow cylinder are for being welded to connect or clamp connection.
?further, described end cap is symmetrical Split type structure.
?further, described middle hollow cylinder is symmetrical Split type structure.
?further, described supporting hollow cylinder is symmetrical Split type structure.
?further, the recessed circular hole that described end cap back side annular arranges is 4.
?the beneficial effect that adopts technique scheme to produce is: a kind of oil field plunger pump gland for packing box of the utility model trip-proof device, device adopts arranged concentric, and the support hollow cylinder of anti-tripping end cap, middle hollow cylinder, position adjustable all adopts symmetrical split-type structural.Trip-proof device end cap is provided with and the corresponding shrinkage pool of plunger pump grease seal end cap nut location, to ensure the close contact of two end cap end face.The utility model preventing plunger pump trip gear, can give the very strong supporting force of plunger displacement pump gland for packing box, when particularly packing has just been changed, the junction button number of packing box and gland is less, its positive role is more obvious, by the effect of an additional support force, utilizes the frame for movement performance of this device can effectively prevent that plunger displacement pump gland for packing box from deviating from, reach the object that ensures safe operation in manufacturing process, can be convenient to again the regular maintenance in manufacturing process.

Detailed description of the invention
?below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
?as shown in accompanying drawing 1-6, a kind of oil field plunger pump gland for packing box trip-proof device, comprise end cap 1, be connected to end cap 1 right side middle hollow cylinder 3, be threaded connection position adjustable on middle hollow cylinder 3 supporting hollow cylinder 4, be arranged in the middle of left setscrew nut 2-1 and the right setscrew nut 2-2 and being arranged at hollow cylinder 3 two ends support near the stiffnut 5 hollow cylinder 4 upper surfaces.Be provided with the recessed circular hole 6 corresponding with plunger pump grease seal end cap nut location at end cap 1 back side, to ensure the close contact of two end cap end face.Be provided with internal thread in middle hollow cylinder 3 inside, on supporting hollow cylinder 4, be provided with the external screw thread corresponding with middle hollow cylinder 3 internal threads.The end cap 1 of trip-proof device and middle hollow cylinder 3 can be combined into a black box, and therebetween by being welded to connect or clamp connection, concrete structure is symmetrical split, the supporting hollow cylinder 4 of built-in adjustable position has the structure of overall cylinder also to be arranged for symmetrical split, ensures that by stiffnut 5 the supporting hollow cylinder 4 of adjusting position has overall cylinder performance, the supporting hollow cylinder 4 of middle hollow cylinder 3 and adjustable position is by being threaded, at setscrew nut 2-1, in the middle of under the effect of 2-2 and stiffnut 5, hollow cylinder 3 and supporting hollow cylinder 4 can have the regulating action of integral hollow cylinder, the change in location of the supporting hollow cylinder 4 by adjustable position, ensure that the end face of the supporting hollow cylinder 4 of position adjustable tightly withstands the end face of plunger displacement pump packing box, give plunger displacement pump packing box a pre-pressure on top surface, thereby reach anti-tripping object, ensured the safe operation in manufacturing process, be convenient to again the regular maintenance in manufacturing process.
