    • It is an object of the invention to provide a pump jack pump-off control method and a pump jack control apparatus in which, even when the speed of a pump jack is reduced due to generation of a pump-off condition, the pump jack is not caused to stop due to the motor overload abnormality or the coagulated crude oil and, even when the pump-off condition is generated, the reduction of the production capacity of the pump jack can be prevented as much as possible. On detecting the pump-off condition, while the pump jack is in operation with the speed thereof being reduced, or while the pump jack is in operation at the lowest speed, according to the overload warning signal of an ac electric motor, the pump jack is switched over to its intermittent operation. Also, the pump jack can be operated in such a manner that the stroke speed of the pump jack in the up stroke operation can be switched from a sinusoidal wave form over to a rectangular wave form, or, in the operation of the pump jack by an inverter, the pump jack can be operated such that it can carry out its up stroke operation with a limit imposed on torque.
    • 本发明的一个目的是提供一种泵千斤顶排水控制方法和一种泵千斤顶控制装置,其中即使当由于产生排水状态而使泵千斤顶的速度降低时,泵千斤顶 不会由于电机过载异常或凝固原油而停止,即使在产生脱离状态的情况下,也能够尽可能地防止泵千斤顶的生产能力的降低。 一旦检测到脱水状态,当泵式千斤顶的运转速度降低时,或者当泵式千斤顶以最低速度运转时,根据交流电动机的过载报警信号,泵的千斤顶 切换到间歇操作。 此外,泵千斤顶可以以这样的方式操作,使得在上行程操作中的泵千斤顶的行程速度可以从正弦波形切换到矩形波形,或者在泵千斤顶的操作中 一个变频器,可以操作泵千斤顶,使其能够以施加扭矩的极限进行上行程操作。
