Abstract

The invention relates to the field of acoustic methods of Hepaapyi monitoring. The aim of the invention is to reduce the consumption of contact liquid when inspecting a product from vertical surfaces due to the formation of a collection funnel with elastic tapes and a guide eaves due to the provision of a device with a tapered roller and a certain arrangement of the device elements. From the feed system 5, the contact liquid 7 penetrates into the slit gap 14 between the transducer 2 and the controlled product 12. Scanning of the product 12 is performed by turning the rollers 1. After the gap 14, the liquid 7 falls on the moving elastic band 3, which collects it into the funnel formed over - by the product 12 and the tapered roller 8 raised by a part of the tape 3. Then the liquid flows onto the elastic wedge-shaped tape 4 ,. deflecting it. inside adjacent to the tape 4 of the pallet 17 of the system 6 removal. Ultimately, the liquid 7 enters the storage tank 19 and out of it through the pump 20 into the supply system 5. 2 Il. c (L 4i 4 D 00: D Figure 1

Description

The invention relates to the field of Acoustic methods of non-destructive testing and can be used lipH ultra sonic (US) defect-proof and various products, for example, coreyB reactors.

The purpose of the invention is to reduce the expansion of contact liquid from the vertical surfaces of the product with its 1 |: control due to the formation of the team hole using one of the elastic jteHT and the eaves to the pallet using another elastic tape.

Figure 1 is a schematic representation of a device for ultrasonic inspection of products; in FIG2 - view A in FIG. 1.

The device for control of products contains two parallel elastic 1: atka 1, an ultrasonic transducer 2 mounted between them, two elastic tapes 3 and 4 connecting the rollers 1, systems 5 and 6 for supplying and removing contact fluid 7 and a tapered roller 8. | In addition, the device contains the rollers 9, providing tension on the belts 3 and 4, the electric motor 10 and the gear 11, degrading the mechanical connection of the electric motor 10 with 1 |) one of the rollers 1 o Piggy 12 marked as a controlled item.

The device also includes an elastic: & 13 element, which performs during the course of)) operation, pressing converter 2 against the surface of the test article 12 with a gap 14. The feed system 5 is made in the form of a tank 15 with an aperture 16 for feeding a contact sensitivity of 7 in the clearance 14. The system 6 is removed. The device is designed as a pallet 17c (by an opening 18 connected to the opening 18 of the accumulation tank 19 and connected to the last pump-out pump 20. - The outlet of the pump 20 of the removal system 6 is connected to the reservoir 15 of the supply system 5 . The thickness of the tapes 3 and 4 exceeds the gap 14. Tape 4 is made in the form of a V-belt. The roller 8 is mounted so as to grow between the rollers 1. and interact with the belt 3, the latter interacts with the rollers 1 and the roller 9 with the inner surface, and with the roller 8 - the external one. tape 4. In a direction parallel to the axis of rotation of the rollers 1, feed system 5, converter 2, tape 3 with roller 8, tape 4 and -pallet 17 of the removal system 6

arranged in series. During the inspection of the product 12 from the vertical surface, the pallet 17 of the removal system 6 takes the lower position, and the rollers 1 interact with the surface of the product 12,

Device for ultrasonic control products works as follows.

The reservoir 15 of the feed system 5 is filled with a contact liquid 7, for example water. The rollers 1 of the device are pressed against the vertical surface of the test article 12, while using an elastic element 13 between the transducer 2 and the surface of the product 12, a slit gap 14 is formed. When the rollers 1 are pressed against the surface of the product 12, the endless elastic bands 3 and 4 are tensioned by the rollers 9 and tightly to the surface of the product 12. During the scanning of the product 12, the electric motor-10 is turned on and through the transmission 11 rotates one of the rollers 1. Also during the scanning, the pump 20 is turned on. The properties of product 12, liquid 7 from tank 15, is fed under converter 2 through opening 16 to a controlled surface from unit 12 and flows along it, forming a local bath in slot 14. Then the liquid 7 falls on a moving endless elastic band 3, which collects it into a funnel formed by the surface of the products 12 and with the roller 8 raised with a part of the band. The band 3 can be made flat. Further, the liquid 7 falls on the moving elastic wedge-shaped tape 4, which forms a cornice above the tray 17 and deflects the liquid inside the tray 17 of the removal system 6. From the pallet 17 through the opening 18, the liquid 7 is discharged into the container 19 and from there pump 20 is supplied to the reservoir, 15. In the container 19, the liquid 7 is settled and, if necessary, cleaned, the ultrasonic transducer 2 controls the product 12,

The device for ultrasonic inspection of products allows to prevent the spreading of the contact liquid to the sides and down both on a flat, ak and a convex surface. Reducing the flow rate of contact liquid by wetting it only controlled

the area of the surface of the product and use to control the contact liquid collected in the storage tank is most pronounced when the cycle is closed, since special sewage is not required for the waste contact liquid in the presence of radioactive - - r4, 1 C1L 1
