It is necessary to keep the preload constant over the speed range of the spindle.

保存在纱锭的速度范围上的预载常数是必需的。

This apparatus is enable to change the rotational speed of the pump in a wide range, to heat recirculating water and to load both axial and radial forces on the pump spindle.

该装置的特点是调速范围大，工作介质温度高，可以同时对泵轴进行径向和轴向加载。
