Abstract
The invention discloses a single-transmitter double-receiver working method for ultrasonic flaw detection. In the method, at least two probes for transmitting and receiving ultrasonic waves are utilized, wherein one of the probes is used for simultaneously transmitting the ultrasonic waves and receiving reflected waves. When two probes or multiple probes are used for ultrasonic flaw detection by adopting the working method, the transmitting probe can transmit the ultrasonic waves and receive the ultrasonic reflected echoes, and can simultaneously perform penetrated flaw detection and reflected flaw detection, thereby improving the operating efficiency of ultrasonic flaw detection, and easily finding and positioning the defect of a detected workpiece.
Description
Technical field
The invention belongs to lossless detection, especially UT (Ultrasonic Testing) detection technique field.
Background technology
At present, UT (Ultrasonic Testing) detects and can be divided into by hyperacoustic emission receive mode: take in concurrently, bill probe defectoscopy; Many probes defectoscopy that double probe testing method that sending and receiving separate and sending and receiving separate.When two probes and many probe carrying out flaw detection, the corresponding receiving transducer of transmitting probe, transmitting probe emission ultrasonic signal, receiving transducer received ultrasonic signal.
Summary of the invention
In view of the deficiencies in the prior art, the objective of the invention is to design two knocking off of a kind of UT (Ultrasonic Testing) detection and make method, make it to realize simultaneously the flaw detection of pulse reflection method and through transmission technique, the defective of easier discovery and coordinate detection workpiece.
The objective of the invention is to realize by following means:
UT (Ultrasonic Testing) detects two knocking off and makes method, adopts at least two probes to carry out hyperacoustic transmitting and receiving.A probe double as emission ultrasound wave is arranged in the described probe and receive reflection wave and use.
Adopt the solution of the present invention, when two probes and many probe carrying out flaw detection, receiving transducer received ultrasonic signal, transmitting probe also received ultrasonic signal except that the emission ultrasonic signal.A probe emission, two probes receive the ultrasonic echo signal can realize pulse reflection method and through transmission technique flaw detection, the defective of easier discovery and coordinate detection workpiece simultaneously.
Description of drawings is as follows:
Fig. 1 is the inventive method principle of work synoptic diagram.
Fig. 2 is the inventive method principle of work synoptic diagram.
Fig. 3 is the inventive method principle of work synoptic diagram.
Fig. 4 is the work block diagram of the present device of two probes of employing.
Embodiment:
The invention will be further described below in conjunction with drawings and Examples.
Technical method such as Fig. 1, Fig. 2, shown in Figure 3 of the present invention's employing: when carrying out the UT (Ultrasonic Testing) detection with two probes or many probes, the ultrasonic emitting probe also can receive ultrasound echo signal, and this is the basis of two receipts technology.When two probe carrying out flaw detection (multi-probe carrying out flaw detection principle is the same with two probes), the receiving transducer received ultrasonic signal carries out carrying out flaw detection, transmitting probe also received ultrasonic signal carries out carrying out flaw detection, and a probe emission ultrasonic signal, a probe receive the easier discovery of detection mode and the location defective of echo when detecting than present two probes.
Embodiment
Fig. 4 has expressed the work block diagram of the present device that adopts two probes, transmitting probe 1, receiving transducer 2, pre-service 3, pre-service 4, passage switching 5, program control amplification, filtering 7, A/D conversion 8, CPU and digital interface 9 thereof, emission control 10, storer 11, keyboard 12, display screen 13, audio driven 14, usb 15, RS232 mouth 16.
Transmitting probe 1 is launched the ultrasonic listening signal under the control of emission control 10, receive the ultrasonic echo signal simultaneously, converts echoed signal to electric signal, send pre-service 3 circuit.Receiving transducer 2 receives the ultrasonic echo signal, converts echoed signal to electric signal, send pre-service 4 circuit.Pre-service 3 circuit carry out amplitude limit to the electric signal that transmitting probe produces.Pre-service 4 circuit carry out amplitude limit to the electric signal that receiving transducer produces.Passage switches 5 by the signal of CPU and digital processing 9 control switching selective reception probe generations or the signal that transmitting probe produces, and send program control amplification 6.Program control amplification 6 amplification channels switch the 5 ultrasonic echo signals of sending here, and gain is by CPU and digital processing 9 controls.7 pairs of signals of filtering carry out low-pass filtering treatment.A/D conversion 8 transfers into simulating signal to digital signal.CPU and digital processing 9 are cores of system, and data are carried out calculation process and storage, and the control peripheral circuit.Emission control 10 control ultrasonic emitting probe emission ultrasound waves.
Storer 11 is the storer of CPU and digital processing 9, is used for stores processor data and result data.Keyboard 12 is accepted button operation, and display screen 13 shows related data and figure, realizes human-computer interaction function.Audio driven 14 drives loudspeaker, produces the voice and the audio alarm sound.Usb 15 is used for unloading data and ROMPaq.RS232 mouth 16 is exported operation informations, is used for the running status of supervisory system.
Obviously, the enforcement of basic scheme of the present invention is not limited to the situation of described two probes of above embodiment, and the present invention is used to have on the equipment of probe (being a plurality of probes) more than two and compares with the equipment that is used for two probes, should not have substantial difference." two a receipts " described in the application is just for the convenience on narrating.Its common advantage is clear and definite: a probe is launched double as reception, one (many) probes reception echo, penetrates flaw detection simultaneously and reflects and detect a flaw, and will improve the operating efficiency that UT (Ultrasonic Testing) detects, the defective of easier discovery and coordinate detection workpiece.
