The utility model content
The purpose of the utility model provides the quantitative non-destructive detecting device of a kind of oil annular tube defective, and the quantitative detecting method that can be defective provides appointed condition.
The quantitative non-destructive detecting device of the described oil annular tube defective of the utility model is to be made up of probe, probe frame, signal wireless transmission and signal amplifying system, ball, stator, mover, support and roller;
The drum type brake stator that twines copper cash is fixed on the support; Three balls are fixed on the stator inner surface; The drum type brake mover that twines copper cash places on the ball, and mover connects as one with the probe frame, and 2-4 probe is along circumferentially evenly being installed in probe frame inside surface; Signal wireless transmission and signal amplifying system and battery are installed on the probe frame outside surface, and are connected with probe; Roller places the support both sides.
Probe is by ac-excited signal coil, and strong magnetoelectricity magnet and magnetosensitive sense original paper constitute; Ac-excited signal coil is a cubic coils; Strong magnetoelectricity magnet is made up of four strong magnetoelectricity magnet of Z direction periphery and the strong magnetoelectricity magnet in Z direction center; Four strong magnetoelectricity magnet of Z direction periphery are evenly arranged in ac-excited signal coil 1 periphery; The strong magnetoelectricity magnet in Z direction center is positioned at ac-excited signal coil center, and is in the opposite direction with the strong magnetoelectricity magnet of Z direction periphery; Magnetosensitive sense original paper is made up of Z direction magnetic field magnetosensitive sense original paper, directions X magnetic field magnetosensitive sense original paper and Y direction magnetic field magnetosensitive sense original paper; Magnetosensitive sense original paper in Z direction magnetic field is made up of four magnetosensitive sense original papers; Be evenly arranged between the strong magnetoelectricity magnet of strong magnetoelectricity magnet in Z direction center and Z direction periphery; Magnetosensitive sense original paper in directions X magnetic field is made up of two magnetosensitive sense original papers; Be arranged between the strong magnetoelectricity magnet of the strong magnetoelectricity magnet in Z direction center and former and later two Z directions periphery, magnetosensitive sense original paper in Y direction magnetic field is made up of two magnetosensitive sense original papers, be arranged in the strong magnetoelectricity magnet in Z direction center and about between two strong magnetoelectricity magnet of Z directions periphery.
According to the thick definite wire circle of detector tube body wall, in the middle of coil, twine electromagnet, electromagnet is also settled in the centre at edge, four limits, and the hub of a spool position is placed X, Y, Z magnetosensitive sense original paper respectively.Link to each other with signal handling equipment with the high-frequency ac electric signal source, coil goes out ac signal at the body surface excitation, acts on the magnetic line of force and produces ultrasonic propagation in the body.When defectiveness, X, Y, Z change to the detected field signal intensity of magnetosensitive sense original paper, begin to detect defective this moment.Recover just often when the magnetic field intensity that probe detects, defective finishes.Set up the funtcional relationship that probe translational speed axial and circumferential on the body surface and signal intensity change the time, can calculate the flaw size size according to the probe signal intensitometer.
Because this technology is an electromagnetic method, has avoided thorough cleaning requirement, than classic method many facilities is arranged; Particularly need not carry out visual inspection to detection zone; Can obtain whole testing result records and be used for examination and alignment purpose,, reduce manually-operated and rely on so that more high reliability to be provided.Because this technology provides great deal of information such as defect length, the degree of depth and position, the result of these detections can be used as historgraphic data recording in computer, is provided with the back data and traces to the source and examine use.
