交通部上海船舶运输科学研究所,采用全部国产化元、器件,经过3年多时间的努力,研制成功了新一代超声波玉石加工机,命名为CK-250-1型。前不久在北京通过定型鉴定。 该机由超声波发生器、振动系统和机床部等三大部分组成。超声波发生器:全晶体管化;输出电功率≥250W(连续可调),工作频率为21kHz±2kHz,输出阻抗:45Ω、50Ω、75Ω、100Ω、150Ω五档;有他激、自激两种工作方式,在满负荷功率下可连续工作8小时,功耗不大于450VA。振动系统:由阶梯式压电型振
Ministry of Communications Shanghai Shipping Institute of Shipping, using all the domestic yuan, devices, after more than three years of hard work, the successful development of a new generation of ultrasonic jade processing machine, named CK-250-1 type. Not long ago in Beijing through the stereotyping. The aircraft by the ultrasonic generator, vibration system and machine parts and other three major components. Ultrasonic generator: all-transistor; output power ≥ 250W (continuously adjustable), the operating frequency of 21kHz ± 2kHz, the output impedance: 45Ω, 50Ω, 75Ω, 100Ω, 150Ω five files; , At full load power can work continuously for 8 hours, the power consumption is not greater than 450VA. Vibration system: by the step-type piezoelectric vibration
