Abstract
The invention discloses a stator of a screw rod pump. The stator is formed by a plurality of substators which are connected in sequence. The substators are made of round steel of 38CrMoAl, a clamping groove and a bump are respectively arranged on the connecting portion of two adjacent substators, the two adjacent substators are welded and connected, and the clamping groove and the bump are matched. The stator is formed by the plurality of the substators, so that the stator of the screw rod pump is convenient to machine and capable of effectively reducing manufacturing cost. Meanwhile, the two adjacent substators are matched, welded and connected through structures of the clamping groove and the bump, so that matching is tight and solid. In addition, the substators are made of the round steel of 38CrMoAl, so that the stator of the screw rod pump has the advantages of being abrasion resistant, high temperature resistant, shock-resistant, and long in service life.
Description
Technical field
The present invention relates to a kind of screw pump, relate in particular to a kind of stator of screw pump.
Background technique
At present, in the oil recovery machiner that use in China oil field, beam pumping unit occupies the majority, it is simple in structure, easy to manufacture, easy to maintenance, energy consumption is high, inefficient problem but it exists, and along with deepening continuously that each elephant of China is developed, the development difficulty in oil field constantly increases, particularly high sand content, viscous crude that viscosity is large use beam pumping unit to be difficult to realize economic, effectively exploitation.In view of the above problems, a kind of have that economic performance is good, pressure is high and even, flow is even, rotating speed is high, have the screw pump of taking the characteristics such as sand function is used widely in thickened oil recovery.Screw pump is the formed engagement spatial volume variation of the dependence pump housing and screw rod and moves and carry liquid to make it to be lifted to the rotary pump of surface duct or container.The existing stator that is used for the screw pump of thickened oil recovery is elastomer stator, and it is wear-resisting, resistance to high temperature is relatively poor, and working life is short, if adopt wear-resisting, resistant to elevated temperatures metallic material manufacturing, stator length is difficult to satisfy the requirement of recovering the oil.
Summary of the invention
The object of the invention is to for the problems referred to above, a kind of stator of screw pump of wear-resisting, high temperature resistant, simple in structure, low cost of manufacture is provided.
The objective of the invention is to be achieved through the following technical solutions:
A kind of stator of screw pump, described stator is made of a plurality of sub-stators that connect successively, and described sub-stator is made by the 38CrMoAl round steel, and the jointing of two adjacent sub-stators is respectively arranged with draw-in groove, projection, and two adjacent sub-stators are welded to connect, and described draw-in groove matches with projection.
Further, described sub-stator and projection are structure as a whole, and sub-stator and draw-in groove are structure as a whole.
Further, described stator integral body is columnar structured.
Beneficial effect of the present invention is that the stator of described screw pump is made of a plurality of sub-stators, is convenient to processing, effectively reduces fabricating cost; And two adjacent sub-stators match by the structure of draw-in groove, projection, and are welded to connect, and cooperate tight, firm; In addition, sub-stator adopts the 38CrMoAl round steel to make, and has the advantage of wear-resisting, high temperature resistant, shock resistance, long service life.
Description of drawings
Fig. 1 is the structural representation of the stator of a kind of screw pump of the present invention.
Among the figure:
1, sub-stator; 2, draw-in groove; 3, projection.
Embodiment
Further specify technological scheme of the present invention below in conjunction with accompanying drawing and by embodiment.
Please refer to shown in Figure 1ly, Fig. 1 is the structural representation of the stator of a kind of screw pump of the present invention; In present embodiment, a kind of stator of screw pump, described stator integral body is columnar structured, it is made of a plurality of sub-stators 1 that connect successively, and described sub-stator 1 is made by the 38CrMoAl round steel, and the jointing of two adjacent sub-stators 1 is respectively arranged with draw-in groove 2, projection 3, and two adjacent sub-stators 1 are welded to connect, described draw-in groove 2 matches with projection 3, and described projection 3 and sub-stator 1 are structure as a whole, and sub-stator 1 and draw-in groove 2 are structure as a whole.
The quantity of sub-stator 1 determines according to required stator length, consists of stator by a plurality of sub-stators 1, is convenient to processing, effectively reduces fabricating cost.
Above embodiment has just set forth basic principle of the present invention and characteristic; the present invention is not limited by above-described embodiment; without departing from the spirit and scope of the present invention, the present invention also has various variations and change, and these variations and change all fall in the claimed scope of the invention.The claimed scope of the present invention is defined by appending claims and equivalent thereof.
