以往调整抽油机每分钟的抽油次数(冲次)是靠更换、调整电动机皮带轮直径来实现的。这种操作费时、费力。目前研制的组合式皮带轮是在小直径基轮之上,根据采油现场对抽油机冲次调整的要求,套上不同直径的轮套来实现的。这一改进措施省去了取下皮带轮工序,操作起来更为省时、省力。
In the past to adjust the pumping unit per minute pumping times (impulse) is replaced by adjusting the diameter of the motor pulley to achieve. This operation is time consuming and laborious. At present, the combined pulley developed on the small-diameter base wheel meets the requirement of adjusting the stroke of the pumping unit according to the oil field and sets the wheel sets of different diameters to achieve. This improvement eliminates the need to remove the pulleys and save time and effort when operating.
