振荡器是生物培养工作中必需的机械设备之一,它广泛应用于生物学、医学、制药、食品等研究和生产单位。因国内多年来使用的振荡器,一般用交流异步电机驱动,通过齿轮箱或皮带轮变速,调速性能大多不完善。这类振荡器功率损耗大,噪声指标高,由于机械摩损严重,维修也较频繁。 Oscillator is one of the necessary mechanical equipment for biological cultivation work. It is widely used in the research and production units of biology, medicine, pharmacy and foodstuffs. Due to the domestic use of oscillators over the years, generally driven by AC induction motor, gear box or pulley speed, speed performance mostly imperfect. Such oscillator power loss, high noise index, due to serious mechanical damage, maintenance is also more frequent.
