Ultrasonic Source for Medical Ultrasonic Diagnostic ultrasonic transducer repair
Ultrasonic transducer, due to accidental damage, less noise corner of the window, the matching layer has a defect, failure of the ultrasonic transducer sealing, ultrasonic transducer of normal use. Test measurements, we found that the transducer leakage current is greater than IO0 / ~ A; for ultrasound power measurement must be used in addition to gas distilled water for acoustic coupling agent, if not repaired transducer, the project can not be measured, and may cause no Ke Wanhui loss. Approach similar to the above: the broken handle clean and dry at 24h, with a liquid silicone rubber deposited equal its cures of measurement transducer leakage current is less than lA, compliance test procedures put into use upon request. In summary, members of metrological verification of medical ultrasonic diagnostic ultrasound on the source of measurement, the first ultrasonic transducer should be checked for damage, and the matching layer acoustic window between the availability of retting and the air exist, such as the existence of ultrasonic transducer to control damage, etc., should be repaired, the repaired ultrasonic transducer should have good moisture sealing insulation, in line with the requirements of metrological verification. Eccentric horizontal circle theodolite rapid adjusting of Lei Feng Wang Jiankun (Tai'an City of Measurement and Testing, Tyan 2710O0) ● theodolite over a period of time use,stivali ugg, due to deformation, gap, determined to prevent the fall, when all 23 balls in the vertical axis of the root, use the vibration and other factors, the level of the dial may appear eccentric. General butter to cement. Remove the instrument shaft seat jacket in a safe condition after the need for dial tone on the eccentric instrument repair, if you do not have the degree of the level of local dial + and then tighten the screws a little loose, and then awarded the Department with the wear plate instrument, then the repair can not be adjusted. Through many years of work put back together the base of real preparation of the adjusting dial +. Practice, summed up a simple repair method of adjusting for the peer reference Secondly, through the eyepiece micrometer 0O, 180 ~, 90 ~, 270 ~ 4 个 to TDJ6 type of theodolite, for example,tory burch, if the level of eccentric position of the dial there eccentric position on the dial, as in 90 offices and 270 sub-dial at the designated time. In a different location on the dial, through the eyepiece micrometer dial points crossed with the naked eye can determine the length of the apparent difference, to determine the length of the instrument line and the line will be worse than the obvious difference between the normal state, indicating the presence dial eccentricity difference. Then stick with a small dial in the radial direction of the adjusting apparatus to carry out. Adjusting of the following sequence: the crossed from the sub-location of a long short dash to the direction of sub-tapping, while the first will be connected to the theodolite and the base screws loose and the edges by tapping in the observation of the micrometer eyepiece, repeated several times, degree of latitude with the naked eye can not see out from the cradle apparatus, and almost put the brake telescope to telescope and instrument panel there is a different location on the sub-crossed the length difference in the degree of the instrument can be considered as the fulcrum of the top bracket will be the main instrument upside down. Stable release, the spin difference between the disc eccentricity are eliminated. Then, the Ministry awarded the equipment from the horizontal circle gently on the bottom of outer shell protecting the four large screws, remove the hand holding the instrument base (to prevent the horizontal deflection dial), fastening the horizontal dial is good, shaft seat jacket in one hand and hold the Department awarded, you can dial up the level of proposed demolition order by the assembly will be good theodolite, and then for examination. And the protection shell and so on. Should pay attention to check on the raised level of stability of the dial are tightened Subscribe \the latest technology, metal cutting research, development and application of new tools, CNC tool system, new cutting tool material, coating technology and equipment, cutting tools CAD / CAM, tool management systems,ugg milano, localization tools, measurement and error theory , development and application of new measuring meter, precision measurement and quality control, coordinate and laser measuring instruments, electronic digital display measuring tools, mold fixture design and technology, hardware and machine tools,ugg boots günstig, products and technology, plant technology innovation and practical technology, technology market and technical seminars. journal for the field of mechanical manufacturing engineering and technical personnel, skilled workers, the research institutes and scientific and technological personnel, the institutions of higher education teachers and students to read.
