ultrasonic converter

Description

Ultrasonic booster can change the amplitude of transducer. Booster is a passive device and cannot produce vibration itself. It is only to output after the input vibration amplitude changed, and finish the impedance conversion at the same time. Under the stimulation of electric field, ultrasonic transducer can produce regular vibration and the amplitude is about *0Î&frac*4;m commonly. That is not enough to directly finish the welding and other working process. Through the suitable booster, the amplitude of ultrasonic can be raised in a large range. Material permiting, the amplitude can exceed **0Î&frac*4;m. We name it as oscillator when connecting ultrasonic transducer with booster into a whole. On another hand, when the booster works vibration through longitudinal and extension, on the both sides of the particle moves in opposite there seems to be a rest section. This section is named nodal point, which is the best-fixed point of the oscillator. To departure from the fixed point will reduce the work efficiency of the oscillator. The transform efficiency of aluminum booster is always high but the intension of material is low, it`s easy to crack and to slip in screw threads;the intension of the steel booster is high but sound impedance is large comparetively;the all round properties of the titanium alloy booster is good but with expensive price and difficult process. Main technical parameter: The range of frequency:*5kHz***0khz The ratio of the amplitude:0.2:**1:*5 Material: alloyed steel, alumnar, and titanium alloy Surface treatment:black oxide, polish, chromium, galvanized
