【摘要】 石油钻机用调速型液力偶合器用于与交流电动机配套而取代柴油机和液力传动装置配套的动力机组。该偶合器由冷却系统、旋转系统、供油系统、排油系统和辅助系统等组成。偶合器具有无级调速且变化范围宽、可空载启动、隔离振动、有过载保护、适应恶劣工况和气候、可手动或自动控制等特点。现场实际运行表明,与电动机配套的2台调速型液力偶合器机组与2台190型柴油机及液力传动装置机组相比,偶合器机组每年可节约电费78.6万元。更多还原

【Abstract】 The speed-adjustable hydraulic coupling for drill rig is used with AC motor to replace the combination of diesel engine and hydraulic drive device. The coupling consists of cooling system,rotating system,oil-supplying system,oil-discharging system and auxiliary system. And it features stepless speed regulation,wide change range,no-loading startup,isolation vibration,overload protection,adaptability for hostile working condition and weather,manual operation and automatic control. The field operation indicates that the two hydraulic couplings with electric motor can save electricity fee of 786 thousands Yuan annually compared with two 190 type diesel engines with hydraulic drive device.更多还原
