电磁涡流剎车又称电磁涡流制动器。它是一种将机械能转换成电能,又将电能转换为热能的能量转换装置。和水剎车一样,它是钻机的一种辅助刹车。早在二十多年前,美国就第一次成功地将这种剎车运用在钻机上。此后,这种技术冒益被人们所重视,并不断得到发展与完善。 Electromagnetic eddy current brake, also known as electromagnetic eddy current brake. It is a kind of energy conversion device that converts mechanical energy into electrical energy and converts electrical energy into thermal energy. Like a water brake, it is an auxiliary brake for the rig. As early as more than two decades ago, the United States successfully applied the brakes to drilling rigs for the first time. Since then, this technology has taken people’s attention, and continue to be developed and improved.
