抽油机定时控制器是用来减少抽油系统的水击影响、抽油杆故障、减速器齿轮磨损、电视停歇时间和动力机燃料消耗的一种装置。它由计时钟和抽空控制器两部分组成。计时时钟主要控制电机合理的停歇时间,抽空控制器控制抽油机排量。 抽空控制器由载荷-时间控制器、电机电流-时间控制器和游梁振动控制器三部分组 Pumping timing controller is a device used to reduce water hammer effects of pumping system, sucker rod failure, gear wear of the reducer, TV pause time and power unit fuel consumption. It consists of clock and evacuation controller of two parts. The timing clock mainly controls the reasonable stopping time of the motor, and the evacuation controller controls the displacement of the pumping unit. The pump-down controller consists of a load-time controller, a motor current-time controller and a beam vibration controller in three parts
