为使抽油机的抽油参数达到最优,就必须调参.而在调参中,只有调冲次才是最经济、最简单、增产见效最快的方法.要调冲次必须拆卸电机上的皮带轮,但因电机与皮带轮长年在风吹雨淋下工作,大部分电机轴与皮带轮都已锈死,采用传统的撬击法以及三角拉力器(一种拆卸电机轴承的专用工具)都很难把皮带轮从电机轴上拆卸下来.为此,大庆采油六厂研制了一套专用拆卸电机皮带轮的抱合式拉力器. In order to make pumping unit pumping parameters to achieve the best, it must be transferred.And in the reference, only the transfer is the most economical and easiest, the most effective way to increase production.To adjust the frequency must be disassembled motor On the pulley, but the motor and the pulley for many years in the wind and rain work, most of the motor shaft and pulley have been rusty, using the traditional method of prizing and Triangle Rally (a special tool for motor motor disassembly) are It is difficult to disassemble the pulley from the motor shaft.To this end, Daqing Oil Production Plant has developed a set of special motor pulley disassembly Coincident Rally.
