通过常规ZJ 70D/DB电驱动钻机的配置,以钻进工况额定泵压和80%额定泵压两个工作点为例,给出了一种功耗计算方法和发热组合方式,提出了冷却系统设计必须注意的主要因素和空调选择的要点。由于石油钻探工作的特殊性,钻探装备需要经常进行搬迁。以晶闸管或IGBT变流调速装置等为核心的各种电驱动控制功能总成的密闭运输单元,称为电控房(SCR/VFD),是石油钻探装备的重要构成之一。电控房的工作环境多种多样,有一般的陆地,也有高温的沙漠,还有极地、海上平台等环境,温
Through the configuration of the conventional ZJ 70D / DB electric drive drilling rig, taking two operating points of rated working pressure and 80% rated pressure of drilling as an example, a calculation method of power consumption and combination of heating are given, and a cooling System design must pay attention to the main factors and air conditioning options. Due to the special nature of oil drilling, drilling equipment needs to be relocated frequently. A closed transport unit of various electric drive control functions, such as an SCR (Electronic Control Room) (SCR / VFD), with thyristors or IGBT variable speed drives as the core, is one of the important components of oil drilling equipment. Electronic control room of the working environment varied, there are general land, but also the high temperature of the desert, as well as polar, offshore platforms and other environments, temperature
