摘要： A pair of parallel metal lances is driven by a transversal drive into and out of heat exchanger tubes. The lances are supported by a plurality of spaced apart, retractable door supports so that the transversal drive mechanism can approach the tube sheet of the heat exchanger tubes as closely as possible. A pair of rotational drive motors rotates the lances at a user controllable speed. As the lances are moved into the tubes, the interlocked support doors retract one at a time, sequentially. Similarly, as the lances are withdrawn from the tubes, the support doors close one at a time in an interlocked fashion.
摘要翻译： 一对平行的金属喷枪由横向驱动器驱动进入和离开热交换器管。 喷枪由多个间隔开的可收回的门支撑件支撑，使得横向驱动机构可以尽可能接近热交换器管的管板。 一对旋转驱动电机以用户可控速度旋转喷枪。 当喷枪移动到管中时，互锁的支撑门依次缩回一个。 类似地，当喷枪从管中取出时，支撑门以互锁的方式一次关闭。
