Abstract
A fixing tool for repairing a screw pump stator is applied to the technical field of maintenance of downhole tools in oil fields, and is particularly used for repairing the screw pump stator. Is characterized in that: the two hoops are respectively made of rectangular steel plates, and the structures of the two hoops are the same; the hoop is provided with a semi-arc plate, flat plates and a vertical plate, the inner diameter of the semi-arc plate is the same as the outer diameter of the screw pump stator, two flat plates are respectively bent outwards at two ends of the semi-arc plate, and a screw hole is respectively arranged on each of the two flat plates; a vertical plate vertical to the plane of the flat plate is bent at the end part of one flat plate; the semicircular arc plates of the two hoops are opposite, screws respectively penetrate through screw holes of the flat plates, and nuts are fixed at the end parts of the screws. The effect is as follows: the screw pump stator is fixed on the outer wall of the screw pump stator during assembly and disassembly, the condition that the stator swings or droops back and forth is overcome, and the safety performance is high; small volume, light weight, time and labor saving.
Description
Technical field
The utility model relates to downhole tool maintenance technique field, oil field, and particularly a kind of specific purpose tool that keeps in repair large and medium-sized screw pump use is a kind of setting tool that keeps in repair screw pump stator.
Background technology
At present, the large and medium-sized screw pump in domestic oil field is when maintenance, and the outer wall of screw pump stator is the cylinder bodily form, is difficult to make the screw pump stator that is keeped in repair to be fixed.Cause that not only the maintenance personal is many, the operating time is long, and labour intensity is big; Because the environment and the space of maintenance are less, make maintenance tool not only not bring into play its effect in addition, bring potential safety operation hidden danger to the maintenance personal on the contrary.
The utility model content
The purpose of this utility model is: a kind of setting tool that keeps in repair screw pump stator is provided, screw pump stator can be fixed.Improve maintenance work efficient, reduce staff labor intensity.Safety coefficient when improving maintenance.
The technical solution adopted in the utility model is: the setting tool of maintenance screw pump stator, comprise two clips, screw and nut, and it is characterized in that: two clips adopt the rectangle steel plate to make respectively, and the structure of two clips is identical; Described clip has semi arch plate, flat board and riser, and the internal diameter of semi arch plate is identical with the external diameter of screw pump stator, to excurvation one flat plate is arranged respectively at the two ends of semi arch plate, and a screw hole is arranged respectively on two flat boards; Therein the end of one flat plate curved have become vertical riser with plate level; The semi arch plate of two clips is relative, is installed with screw in the screw hole of described flat board respectively, and the end of screw is fixed with nut.Screw nut, can be fixed on two clips on the outer wall of screw pump stator,
The semi arch plate of described two clips relatively after, the distance between the plate level at two semi arch plate two ends is between 4～15mm.
The principle of the setting tool of summary maintenance screw pump stator: when maintenance maintenance screw pump stator, two semi arch plates are placed on relatively on the outer wall of maintenance screw pump stator, put on the screw threads jack panel.Just can carry out the installation or removal of equipment.
The beneficial effects of the utility model: the setting tool of the utility model maintenance screw pump stator, be fixed on during dismounting on the outer wall of screw pump stator, overcome that stator swings back and forth or sagging situation, the security performance height; Volume is little, and is in light weight, time saving and energy saving.Utilize this instrument the runner of screw pump stator can be fixed on a direction, avoided regulating back and forth stator.
Description of drawings
Fig. 1 is the setting tool structural representation of the utility model maintenance screw pump stator.
Fig. 2 is the vertical view of Fig. 1.
Among the figure, 1-riser, 2-flat board, 3-semi arch plate, 4-screw, 5-nut.
The specific embodiment
Embodiment 1: the setting tool with a maintenance screw pump stator is an example, and the utility model is described in further detail.The external diameter of maintenance screw pump stator is 224mm.
Consult Fig. 1.The setting tool of the utility model maintenance screw pump stator comprises two clips, screw 4 and nut 4.
It is 50mm that two clips adopt width respectively, and thickness is that the rectangle steel plate of 6mm is made, and the structure of two clips is identical.Described clip has semi arch plate 3, flat board 2 and riser 1, and the internal diameter of semi arch plate 3 is identical with the external diameter of screw pump stator, is 224mm.There is one flat plate 2 at two ends at semi arch plate 3 to excurvation respectively, dull and stereotyped 2 length 70mm.It is 17 screw hole that a diameter is arranged respectively on two flat boards 2.The end of one flat plate 2 is bent to have with dull and stereotyped 2 planes and is become vertical riser 1, the length 200mm of riser 1 therein.The semi arch plate 3 of two clips is relative, the semi arch plate 3 of two clips relatively after, the distance between flat board 2 planes at two semi arch plate 3 two ends is 14mm.Be installed with the screw 4 of M16 in described dull and stereotyped 2 screw hole respectively, the end of the screw 4 of M16 is fixed with the nut 5 of a M16.Screw nut 5, can be fixed on two clips on the outer wall of screw pump stator,
