Description
Technical field
A kind of oil pipe leakage magnetic detection device is the modifying device that the oil field oil sampling drawn tube is carried out Magnetic Flux Leakage Inspecting.
Background technology
Oil sampling drawn tube is the important equipment of production on artificial lift, in use ruptures in order to prevent oil sampling drawn tube, must carry out carrying out flaw detection to its surface and underbead crack, shortcoming.And the present reliability that is mostly to judge by Magnetic Flux Leakage Inspecting oil sampling drawn tube, and the device that uses generally is with 3 function differences, independently saturation coil, degaussion coil and the arrangement of magnetic test coil coaxial cable separately, it is bulky, complex structure, accuracy of detection are low, is difficult for realizing integrated detection.
Summary of the invention
The oil pipe leakage magnetic detection device is a kind of modifying device that is used for oil field oil sampling drawn tube Magnetic Flux Leakage Inspecting.It unifies saturation coil and degaussion coil, and is distributed on the same circumference with magnetic test coil, thereby has dwindled volume, simplifies the structure, and has improved accuracy of detection, helps realizing integrated detection.
The oil pipe leakage magnetic detection device comprises bearing, overcoat, bar hole, aperture end plate, macropore end plate, interior cover, driving stem, ramp, support, push rod, roller, spring, saturation coil and magnetic test coil.Wherein the upstanding portion of inverted T shape bearing and top are connected along the cylindrical jacket that circumferentially has bar hole, and a side is with the shutoff of aperture end plate, and opposite side is with the shutoff of macropore end plate, and overcoat, aperture, macropore three are concentric.In cover and overcoat movingly, driving stem passes described bar hole and puts in being fixed on.So when driving stem was mobile in the stroke that bar hole limits, the relative overcoat of interior cover turned over certain angle.Uniform 4, thickness even ramps of becoming isometric on the inwall of interior cover with bar hole.4 supports that the position is corresponding with ramp are circumferentially equidistantly fixed in the inwall upper edge of aperture end plate, the push rod of an outside of each plug-in mounting band roller in radially the perforate on it, and its inner cambered surface can contact with the intimate of oil sampling drawn tube.Above-mentioned installation should guarantee, when driving stem when an end of bar hole moves on to the other end, under the drive of interior cover, the roller on the push rod will move on to the other end from an end of ramp, cause push rod radially to move in support, and then adapt to the oil sampling drawn tube of different-diameter.1 saturation coil of each suit on a pair of horizontal stand of positioned opposite, and respectively place 1 magnetic test coil passing another push rod the inner to the vertical support.The spring that is sleeved on the push rod helps push rod to reset.
When using the utility model to carry out oil sampling drawn tube flaw detection work, only need to move driving stem according to the oil sampling drawn tube diameter, the opening and closing push rod inserts oil sampling drawn tube in the space that surrounds between the push rod cambered surface, adjust driving stem again, the inner cambered surface of push rod is contacted with the oil sampling drawn tube intimate get final product.The drive unit supporting with the utility model will drive oil sampling drawn tube uniform rotation, feeding, finish the flaw detection work on whole pipe ranges.
During detection, reach capacity for earlier the saturation coil excitation, by the magnetic leakage flux on the magnetic test coil detection oil sampling drawn tube, the power supply mode that changes saturation coil is afterwards demagnetized.
The utility model compact conformation, volume is little, accuracy of detection is high, realizes that easily electromechanical integration detects.
