Description
Technical field
The utility model relates to a kind of pump, especially relates to a kind of screw pump for underground mining viscous crude.
Background technique
The developing history of volute pump is longer, can trace back to mid-term nineteen twenties, is invented at first by the artificer of France, through the technical perfection of decades, is widely applied in every field.
Its basic working principle is such: be interference fit in subsurface progressive cavity rotor and stator rubber, when rotor when making planet gyration around the axis of stator in die cavity, turn the airtight wrist formed between stator and just produce displacement along rotor helical, can by medium continuously, average rate ground, constant volume ground are delivered to from suction port and are extruded end.
Subsurface progressive cavity has had the development of more than ten years, and quality of product obtains constantly perfect, and on-the-spot application area constantly expands, and displacement range is large, can meet the exploitation of sand containing crude oil, high live crude, and the needs of heavy oil cold flow production.
The screw pump parameter of present employing can reach: discharge capacity: 3 ~ 300m3/d, range of lift: 500 ~ 2000m, rotating speed: 60 ~ 200r/min, medium viscosity: <8000mpa*s, and medium contains sand :≤3%, medium gassiness :≤90%.
But current screw rod stator is metal tube liner rubber structure, and adopt over-surplus fit structure, the needs to the not enough well of feed flow, high-temp thermal recovery well cannot be met, and General Purpose Rubber volute pump is only suitable for cold adopting.
Summary of the invention
For the problems referred to above, the purpose of this utility model is to provide the screw pump of the high temperature resistant all-metal screw pump of a kind of MEC400 Thickened oil injection-production integration, energy conservation.
To achieve these goals, the technical solution of the utility model is yes: the high temperature resistant all-metal screw pump of a kind of MEC400 Thickened oil injection-production integration, it is characterized in that: comprise by metal stator, metallic rotator, screw pump upper connection, screw pump lower contact and snubber, described metallic rotator one end is connected with screw pump upper connection, the other end is connected with screw pump lower contact, described metal stator design is enclosed within metal stator outside, and described snubber is arranged between described lower contact and metallic rotator.
Further, described screw pump rotor, screw pump stator material are alloyed steel, stator surface hardness HV900-950, rotor surface hardness HV500-550.
The metal stator characteristic of hot extracting thick oil metal stator screw pump makes it eliminate conventional rubber stator screw pump not heatproof, easily swelling, easy to wear, the shortcomings such as the life-span is short, have application area widely simultaneously, can except works fine except at most hole condition, also be widely used in high viscosity, Gao Hansha, high corrosion, the oil well of high gassiness, particularly needs the oil well of heating exploitation.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1: the utility model structural drawing.
Wherein, 1, metal stator; 2, metallic rotator; 3, screw pump upper connection; 4, screw pump lower contact; 5, snubber.
Embodiment
The technological means realized to make the utility model, creation characteristic, reaching object and effect is easy to understand, below in conjunction with concrete diagram, setting forth the utility model further.
As Fig. 1, the high temperature resistant all-metal screw pump of a kind of MEC400 Thickened oil injection-production integration, comprise by metal stator, metallic rotator, screw pump upper connection, screw pump lower contact and snubber, described metallic rotator one end is connected with screw pump upper connection, the other end is connected with screw pump lower contact, described metal stator design is enclosed within metal stator outside, and described snubber is arranged between described lower contact and metallic rotator.
Ground drives hot extracting thick oil metal stator screw pump to be a kind of efficient, energy-conservation oil field equipment, primarily of metal stator, and metallic rotator, screw pump upper connection, screw pump lower contact, the parts compositions such as snubber.Metal stator and metallic rotator material are all superior alloy steel through milling with whirling cutter processing and the strengthening of glow discharge nitriding artistic face, stator surface hardness HV900-950, rotor surface hardness HV500-550, metal stator and metallic rotator machining accuracy high, surface hardness is high, has good wear resistance, heat resistance and corrosion resistance.Metal stator is sleeved in outer tube after the single-unit stator combination by multiple same size to form.
It is high that ground drives hot extracting thick oil metal stator screw pump to have precision, and quality is good, and long service life is wear-resistant, high temperature resistant, corrosion-resistant, and moment of torsion is little, easily changes, the features such as oil producing operation expense is low after rotor wearing and tearing.
The metal stator characteristic of hot extracting thick oil metal stator screw pump makes it eliminate conventional rubber stator screw pump not heatproof, easily swelling, easy to wear, the shortcomings such as the life-span is short, have application area widely simultaneously, can except works fine except at most hole condition, also be widely used in high viscosity, Gao Hansha, high corrosion, the oil well of high gassiness, particularly needs the oil well of heating exploitation.
More than show and describe basic principle of the present utility model and major character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and specification just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
