盘式刹车热状态的计算与分析

依据钻采设备刹车装置的工作原理和热传递的基本理论,对盘式刹车工作过程的实际物理现象做了合理的抽象,建立了热物理模型和相应的热传递数学模型。在研究一般钻采设备盘式刹车工作过程的基础上,以石油大学设计、用于30t修井机的YPS20型盘式刹车为例,计算了它在连续下放油管柱时的溫度场,并阐明了它的温度特征。

Calculation and analysis of the thermal state of disc brakes

According to the working principle of the braking device on drilling and production equipment and the basic theory of heat transfer, this article takes a rational abstraction of the actual physical phenomena of the disc brake in operation, establishes a thermal physical model and the corresponding thermal transfer mathematical model, and taking the disc brake on a 30t workover rig as an example, calculates its temperature field and expounds its temperature features as the disc brake is used to run continuously the tubing string.
