    摘要： A driving device for a vortex mixing apparatus comprises holders for holding a mixing unit of a type having at each opposite end a pumping diaphragm for imposing a pulsatile flow on a liquid passing through a primary channel in the unit. Two pistons are each arranged to cooperate with a respective one of the diaphragms and to reciprocate between a retracted position clear of the unit and an extended position in which it extends into a housing of the unit and compresses the respective diaphragm. Driving mechanisms are normally arranged to reciprocate the pistons in phase at the same frequency such that when one piston is moving from its retracted position to its extended position the other is moving from its extended position to its retracted position and vice versa. Control mechanisms are arranged, upon stopping of the driving mechanisms, to cause both pistons to adopt retracted positions so that the unit may be inserted into, and removed from the holders without interference from the pistons.

    摘要翻译： 用于涡流混合装置的驱动装置包括用于保持混合单元的保持器，该混合单元在每个相对端具有泵送隔膜，用于在穿过该单元中的主通道的液体上施加脉动流。 两个活塞各自布置成与相应的一个隔膜协作并且在远离单元的缩回位置和延伸位置之间往复运动，在该延伸位置中，两个活塞延伸到单元的壳体中并压缩相应的隔膜。 驱动机构通常布置成以相同的频率使活塞往复运动，使得当一个活塞从其缩回位置移动到其延伸位置时，另一个活塞从其延伸位置移动到其缩回位置，反之亦然。 控制机构在驱动机构停止时被布置成使两个活塞采用缩回位置，使得该单元可以在不受活塞干扰的情况下被插入和移出。
