Abstract: A braking arrangement for drive heads or pump heads, to be preferably used in a progressing cavity pump (PCP) system in oilfields, consisting of at least one disk moving inside a viscous fluid and facing a static disk, in which mechanical energy is transformed into heat. The viscous brake is a device acting as a function of the rotation speed, in which a higher speed generates a higher braking power caused by the increase of friction among the disks and the fluid. The arrangement may comprise more than one mobile and static disk assemblies, as well as a hollow axis instead of a solid one, to allow housing the pumping rod inside the axis, and may also comprise an anti-reverse bearing.

Abstract translation: 用于驱动头或泵头的制动装置优选用于油田中的前进空腔泵（PCP）系统中，由至少一个在粘性流体内移动并面向静态盘的盘组成，其中机械能被转换成 热。 粘性制动器是作为转速的函数的装置，其中较高的速度产生由盘和流体之间的摩擦增加引起的更高的制动功率。 该装置可以包括多于一个的移动和静止盘组件以及空心轴线而不是固体轴承，以允许泵送杆在轴线内容纳，并且还可以包括防反向轴承。
