Technical field
The utility model relates to the pick-up unit technical field of air drilling mesohigh manifold, is mainly used for, in drilling process, the wall thickness of high pressure pipe joint is carried out to Real-Time Monitoring.
Background technology
High pressure pipe joint is widely used among the public lives such as the industry production such as petrochemical complex, metallurgy, electric power and gas and heating system, is undertaking the conveying task of high temperature, high pressure, inflammable, explosive and poisonous medium.Growth along with service time, its tube wall is because being subject to the effects such as fluid scouring, galvanic corrosion, can progressively there is tube wall attenuate, crackle and corrosion failure in manifold, especially at elbow, threeway, caliber mutable site and adjacent straight tube position, finally cause transfer efficiency to reduce, if can not find in time to change the pipeline of seriously corroded, when serious, easily leak, once occur to leak or blast, likely cause catastrophic accident.Therefore manifold being carried out to in-service detection is extremely necessary.
Traditional ultrasonic sensor manufacturing cost is high, and has the coupled problem that causes the loss of signal or read untrue.Good ultrasonic transmission depends on all air of removing between sensor and test surfaces, enough readings and metering design guarantee that ultrasonic sensor is with the minimum loss of signal or decay, as transmitted and received signal in the situation that not there is not bubble or gap.Ultrasonic sensor typical case utilizes couplant to strengthen the transmission between test material and sensor.Traditional fluid couplant comprises propylene glycol or glycerine.Fluid couplant becomes dry, and spills or overflow below sensor, and this causes signal transmission issues.The people such as Cawley disclose a kind of elongate strip of ultrasound wave emissive material in international application published WO2007/051959.
In industry, attempted magnet or bonding agent for transfer of ultrasonic energy system.Yet these bonding agents weaken or break due to As time goes on bonding, have the problem that crash rate is high.From the energy of ultrasonic sensor input, also may aggravate adhesive failure.The United States Patent (USP) 4881409 of Roarty discloses a kind of flexible magnetic material with array of ultrasonic sensors.The people's such as Fripp United States Patent (USP) 7234519 discloses transducer has been bonded to the pipeline for petroleum drilling.Although magnetic or bonding agent can provide the signal transmission of longer time before bonding agent lost efficacy than fluid couplant, but need the ultrasonic sensor of longer or permanent installation service time.
Summary of the invention
For solving the existing technical matters of above-mentioned prior art, the utility model proposes the ultrasonic probe of the permanent installation of a kind of dry coupling, adopt the not restriction of examined position of the utility model, convenient and reliable, and solved the technical matters of " it is not high that the conventional ultrasonic hand-held thicknessmeter using is measured reliability ".
The utility model adopts following technical proposals to realize by employing:
The ultrasonic probe of the permanent installation of a kind of dry coupling, it is characterized in that: comprise ultrasonic probe, probe mounting frame, probe fixing bracket and dry coupling material layer, described probe mounting frame and probe fixing bracket link into an integrated entity, ultrasonic probe is arranged in the inner chamber of probe mounting frame, below ultrasonic probe, be provided with dry coupling material layer, probe mounting frame is laminated to ultrasonic probe and dry coupling material on the high pressure pipe joint that will install by probe fixing bracket.
Described dry coupling material layer is the layer structure of being made by silica gel.
Described probe mounting frame and probe fixing bracket are integrated, and probe mounting frame and probe fixing bracket form installs fixed housing, and it is shaped as open-topped cowboy's hat.
Described ultrasonic probe is that a plurality of, all ultrasonic probes is all connected with an audiogage.
Compared with prior art, the beneficial effect that the utility model reaches is as follows:
One, in the utility model, by adopting the technical scheme of " being provided with probe mounting frame and probe fixing bracket outward at ultrasonic probe; probe mounting frame is laminated to ultrasonic probe and dry coupling material on the high pressure pipe joint that will install by probe fixing bracket ", there is following technique effect:
1, the utility model adopts dry coupling material layer, can not affect the presentation quality of tested steel pipe, and the impact of the acoustic noise of having stopped fluid couplant on thickness measuring signal, reduces the maintenance workload of equipment.
2, the version that adopts probe mounting frame and probe fixing bracket, ultrasonic probe and high pressure pipe joint permanent contact, reduced manual operation, improved security and the integrality of thickness measuring.
3, adopt the utility model, ultrasonic probe is directly disposably and permanently arranged on elbow, and be connected to instrument and then pass the signal in the display device in pulpit.If bend is operated in eminence (being above the ground level 6 meters), can stops technician and climb the dangerous situations such as framing scaffold and cost saving.Meanwhile in ultrasonic probe transducer with workpiece without directly contacting, greatly extended the serviceable life of probe.
Two, in the utility model, the version that adopts " described probe mounting frame and probe fixing bracket are integrated; probe mounting frame and probe fixing bracket form installs fixed housing; it is shaped as open-topped cowboy's hat; ultrasonic probe is a plurality of; all ultrasonic probes are all connected with an audiogage ", has following technique effect:
1, thickness measuring is highly sensitive: the precision of this thickness measuring system can reach 0.1mm.
2, can monitor numerous probes.
In the utility model, all probes are all connected to an audiogage, and audiogage is connected to main frame by netting twine.Between probe and Ultrasound Instrument, equal connecting multi-channel relay, is controlled by single-chip microcomputer by multistage one minute eight switches.Realized the thickness monitoring to each measuring point.
3, automaticity is high.
Trunk coupling ultrasonic probe can be realized in-service detection, save time, and will show successively the thickness measuring signal of all probes of diverse location on main frame, and autostore detects data.Meanwhile can also manually recall the pipe thickness information of optional position.The continuous monitoring of realization to pipe thickness, controls steel pipe thickness abrasion condition in time.When tube wall is thinned to wall thickness minimum threshold, by showing on computers, the direct economic effect indirect economic effect of acquisition.
