Abstract
The invention relates to a water outlet section for a submersible electric pump in a deep well and a machining method. The water outlet section comprises a water outlet section body; a flaring port is formed at one end of the water outlet section body through a flaring port transition section; a necking port is formed at the other end of the water outlet section body through a necking port transition section; an external thread which is matched with a pump body thread is arranged at the flaring port; and an internal thread is arranged at the necking port. The machining method comprises the following steps of: selecting and using a tubular product, mechanically controlling a total length, forming the flaring port after flaring at one end through a stamping technology, then forming the necking port at the other end and finally machining the external thread at the flaring port, the internal thread at the necking port and an annular convex shoulder. The water outlet section has the beneficial effects that the integrated water outlet section is low in the cost of materials and simple in working procedures, has better stability and is suitable for the submersible electric pump in the deep well.
Description
Technical field
The present invention relates to the water pump field, especially a kind of water exit end and processing method that is used on the deep-well Submerged Motor Pumps.
Background technique
The existing water exit end that is used on the deep-well Submerged Motor Pumps has two kinds: a kind of water exit end for being connected with the pump housing through screw thread, a kind of is the water exit end that is connected with the pump housing through pull bar.Before a kind of manufacturing process of water exit end of Placement, be well known that two kinds of branches, a kind of for casting forms, a kind ofly be welded for many parts.Water exit end on the existing deep-well Submerged Motor Pumps exists with the material cost high, and operation is loaded down with trivial details, the deficiency that pore is wayward with folder sand, product stability is relatively poor.
Summary of the invention
The objective of the invention is to the existing water exit end that is used on the deep-well Submerged Motor Pumps existing high with the material cost; Operation is loaded down with trivial details; The deficiency that pore is wayward with folder sand, product stability is relatively poor; Provide a kind of low with the material cost, operation is simple, the stable water exit end and the processing method that is used for the deep-well Submerged Motor Pumps preferably of product.
The present invention solves the technological scheme that its technical problem adopts: this water exit end that is used on the deep-well Submerged Motor Pumps, comprise the water outlet segment body, and an end of water outlet segment body forms enlarging through the enlarging changeover portion, and the other end of water outlet segment body forms reducing through the reducing changeover portion; Be provided with the outside thread with pump housing screw-thread fit in enlarging place, be provided with internal thread in reducing place.
As preferably, form annular convex shoulder in described enlarging and enlarging changeover portion joint.
This processing method that is used for the water exit end on the deep-well Submerged Motor Pumps of the present invention; Comprise that step is following: select tubing for use; Car control length overall; Through forming enlarging after the stamping process enlarging at one end, and then form reducing, process the outside thread of enlarging place, the internal thread and the annular convex shoulder of reducing place at last at the other end.
As preferably, described tubing is big thick walled steel tube.
The effect that the present invention is useful is: provide a kind of low with the material cost, operation is simple, the stable integral type water exit end that is used for the deep-well Submerged Motor Pumps preferably of product.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Description of reference numerals: water outlet segment body 1, enlarging 1-1, reducing 1-2, enlarging changeover portion, 1-3, reducing changeover portion 1-4, annular convex shoulder 2.
Embodiment
Below in conjunction with accompanying drawing the present invention is described further:
As shown in the figure, this water exit end that is used on the deep-well Submerged Motor Pumps comprises water outlet segment body 1, and an end of water outlet segment body 1 forms enlarging 1-1 through enlarging changeover portion 1-3, and the other end of water outlet segment body 1 forms reducing 1-2 through reducing changeover portion 1-4; Be provided with the outside thread with pump housing screw-thread fit at enlarging 1-1 place, be provided with internal thread at reducing 1-2 place.Form annular convex shoulder 2 at described enlarging 1-1 and enlarging changeover portion 1-3 joint.
This processing method that is used for the water exit end on the deep-well Submerged Motor Pumps of the present invention; Comprise that step is following: select for use big thick walled steel tube as tubing, car control length overall is through repeatedly punching press of stamping process; At one end form enlarging 1-1 after the enlarging; And then, process the outside thread at enlarging 1-1 place, the internal thread and the annular convex shoulder 2 at reducing 1-2 place at last at the other end formation reducing 1-2, process through fine finishing.
When water exit end of the present invention and pump housing assembling, the outside thread that is located at the big end of water exit end is threaded together with the pump housing.During being connected of water exit end and the pump housing, carry out spacingly through the ring-like convex shoulder 2 that is located at water exit end, the sealing configuration between the water exit end and the pump housing is made up of outside thread that is located at its big end and the annular convex shoulder of establishing above that 2.
Except that the foregoing description, the present invention can also have other mode of executions.All employings are equal to the technological scheme of replacement or equivalent transformation formation, all drop on the protection domain of requirement of the present invention.
