Abstract
The invention provides a spraying device of a magnetic powder flaw defector. In the magnetic powder flaw defection, small defects will be missed for defection if concentration of a magnetic suspension is too low; contrast will be reduced if the concentration is too high, the concentration of the magnetic suspension will be reduced gradually due to reasons of magnetic powder precipitation, absorption by containers and the like in the detection process, and further the accuracy of magnetic powder flaw defection results is affected. The spraying device comprises a suspension collecting tank (1). A sealing box (2) is mounted in the suspension collecting pool , a motor (3) is mounted in the sealing box, power output shafts (4) are arranged on the upper side and the lower side of the motor respectively, a group of impellers (5) are mounted on the power output shafts on the upper side of the motor, a group of reversion water wheels (6) are mounted on the power output shafts on the lower side of the motor, and a distributor (7) is mounted above the impellers, and the distributer is connected with a group of spraying pipes (8). The spraying device is used for ancillary facilities of magnetic powder flaw defectors.
Description
Technical field
The present invention relates to a kind of extraordinary chemical plant pick-up unit, be specifically related to a kind of spray equipment of magnaflux.
Background technology
Magnetic powder inspection is after utilizing ferrimagnet to be magnetized; Because discontinuous existence; Local distortion takes place and produces stray field (being the magnetic field that lines of magnetic induction leaves and forms when getting into the surface) absorption and be applied to the magnetic of surface of the work in the magnetic line of force that makes surface of the work and nearly surface; Be formed on appropriate light and shine visual visible magnetic trace down, thereby demonstrate position, shape and the size of uncontinuity.Magnetic powder inspection can detect defectives such as crackle in the ferrimagnet, hairline, white point, folding, snotter, has very high detection sensitivity, and can demonstrate position, shape, size and the order of severity of defective intuitively, the good reproducibility of inspection defective.In tubing, bar, section bar, weldment, machined piece, forging flaw detection, obtained using widely, especially pressure vessel decide bringing into play unique effect in the inspection especially.The magnetic trace shows that degree not only shows that with defect property, magnetization degree, magnetic application process and workpiece state is relevant, and is also relevant with this character such as magnetic, granularity, shape, density activity, resolution, concentration of magnetic; For black particle and red particle that wet method is used, the concentration of magnetic flaw detection ink is too low, little defective meeting omission; Concentration is too high, can make the reduction contrast, and can on the magnetic pole of workpiece, attach excessive magnetic, disturbs the demonstration of defective, so the concentration of magnetic flaw detection ink will suit in the testing process.Owing to the deposition of magnetic in the testing process, the reasons such as absorption of receptor, cause the concentration of magnetic flaw detection ink to reduce gradually, thereby influence the result's of magnetic powder inspection accuracy.
Summary of the invention
The objective of the invention is to provide a kind of spray equipment of magnaflux, can effectively avoid the deposition of magnetic in the magnetic flaw detection ink, make that the result of magnetic powder inspection is more accurate to the problem of above-mentioned existence.
Above-mentioned purpose realizes through following technical scheme:
The spray equipment of magnaflux comprises the magnetic flaw detection ink collecting pit, in the described magnetic flaw detection ink collecting pit seal box is installed; Motor is installed in described seal box the inside; The upper and lower both sides of described motor have PTO respectively, are positioned at one group of impeller is installed on the PTO of described motor upside, are positioned on the PTO of described motor downside one group of wheel of turning one's coat is installed; Divider is installed in described impeller top, and described divider connects one group of shower.
The spray equipment of described magnaflux, described shower linearly type are arranged.
The spray equipment of described magnaflux, described shower is circle-shaped arrangement.
Beneficial effect:
1. the present invention adopts two groups of reverse impellers of a driven by motor; Top impeller is used for magnetic flaw detection ink is drawn into divider; Following reverse impeller is used for suspending liquid is washed downwards; Avoid the deposition of magnetic, made the concentration of magnetic flaw detection ink in the magnetic powder inspection process keep stable as far as possible, helped the accuracy of result of detection.
2. the present invention is arranged to different spread geometries in order to use the shape of different equipment to be detected with shower.
Description of drawings
Fig. 1, structural representation of the present invention.
Fig. 2, the structural representation when shower of the present invention is arranged in a linear.
Fig. 3, the structural representation when shower of the present invention is circumferential arrangement.
