Abstract
The utility model relates to an ultrasonic transducer used in petroleum industry, mainly comprising an annular ultrasonic wave oscillator which is fixed by a top and a bottom connecting sleeves, a connecting rod and a support ring. The utility model is characterized in that the ultrasonic wave oscillator ring is a vacuum cavity, the outer sides of the top and the bottom connecting sleeves are provided with rubber protective sleeves for sealing the ultrasonic wave oscillator. With adopting the vacuum structure, the utility model can effectively prevent internal radiation and can increase ultrasonic transducing efficiency, and meanwhile, the utility model can solves the problem that large power heating causes a radiation surface to separate from a protective layer. So the utility model can be used for petroleum emulsion, petroleum pipeline descaling, etc.
Description
The utility model relates to a kind of ultrasonic transducer that is used for petroleum industry ultrasonic cleaning, ultrasonic emulsification.
The present used ultrasonic transducer of petroleum industry, its ultrasonic oscillator inboard is provided with media such as foam, silicone oil, when ultrasonic oscillator receives when being vibrated by electrical power emitter emitted power and electrical signal of the frequency, cause that the inside and outside medium of oscillator vibrates simultaneously, promptly to inside and outside while emittance.Because the phase place of the inside and outside vibration of oscillator opposite (phase difference 180 degree), like this in radiate supersonic wave pass to the oscillator outer surface by medium, and subtract each other to extraradial ultrasonic wave, make to extraradial ultrasonic energy and weaken, thereby make the reduction of ultrasonic transducer efficient.In addition, owing to have the energy of inside radiation, the protective layer heating that the ultrasonic oscillator outer surface is joined with it is thrown off, and also influences the efficient of transducer.
At the deficiency that above-mentioned prior art exists, the purpose of this utility model provides a kind of ultrasonic transducer that improves conversion efficiency.
The purpose of this utility model is achieved in that it mainly comprises by by the fixing ring-type ultrasonic oscillator of upper and lower adapter sleeve, connecting rod and support ring, is characterized in that; In the ultrasonic oscillator ring is vacuum chamber, and the upper and lower adapter sleeve outside is provided with the rubber sheath of sealing ultrasonic oscillator.
The utility model is because the inboard vacuum structure that adopts of ultrasonic oscillator; effectively carried out acoustic shielding; make the acoustic energy of inside radiation ease down to zero; promptly there is not interior radiation problem; thereby ultrasonic transduction efficient is improved greatly; ultrasonic oscillator external radiation face and rubber sheath are tightly joined, can guarantee acoustic energy, can better solve the problem that high-power heating is thrown off radiating surface and protective layer again to external radiation.
Below in conjunction with accompanying drawing the utility model is explained.
Accompanying drawing is the utility model structural representation.
By accompanying drawing as can be known, the utility model is made of upper and lower adapter sleeve 3,10, connecting rod 6, support ring 8, ultrasonic oscillator 5, rubber sheath 4, it is fixing to go up lower joint sleeve 3,10 by connecting rod 6, by support ring 8 that ultrasonic oscillator 5 is fixing upward between the lower joint sleeve, rubber sheath 4 places the lower joint sleeve outside and ultrasonic oscillator is sealed in it, ultrasonic oscillator 5 adopts the piezoelectric ceramics annulus, and its outer felt makes it have certain stress that gives around epoxy fibreglass 11.Ultrasonic oscillator 5 ring inboards are vacuum chamber 7, are the cable connectors 2 of connection electrical power emitter cable 1 with ultrasonic oscillator above the upper joint sleeve 3.Steam vent 9 in the accompanying drawing vacuumizes usefulness.By cable 1, cable connectors 2 the large power, electrically signal that the electrical power emitter sends is delivered to ultrasonic oscillator, and by its conversion acoustic energy signal by rubber sheath to external radiation, can be used for petroleum emulsification and pipeline antiscale.For example, when when extraradial ultrasonic wave is propagated along petroleum pipeline is surperficial, can cause between salt crust particulate and the metal surface shear action takes place, thereby hinder the formation of salt crust.
