1.结构及工作原理多用拆装机由液压系统和机械系统两部分组成.液压系统包括液动钳油缸、固定钳油缸、手摇泵和液压操作箱.机械系统包括液动钳、固定钳、支承轮和机座.其工作原理是:由液压操纵箱控制液压缸动作,液压缸的活塞杆与曲臂一端相连,曲臂另一端装有链片及变径钳牙组成的自动锁紧机构.当活塞上行时,钳牙放松,活塞下行时,钳牙自动咬紧接箍随活塞的下行做圆周运动,从而实现上、卸丝扣的目的.多用拆装机主要用途是拆装深井泵、封隔器及其他用丝扣连接的井下作业工具.
1. Structure and working principle The multi-purpose disassembly machine is composed of hydraulic system and mechanical system.The hydraulic system includes hydraulic vise cylinder, fixed vane cylinder, hand pump and hydraulic operation box.The mechanical system includes hydraulic clamp, fixed clamp, Supporting wheel and base.Its working principle is: the hydraulic control box controls the action of the hydraulic cylinder, the piston rod of the hydraulic cylinder is connected with one end of the crank arm, the other end of the crank arm is equipped with an automatic locking mechanism When the piston goes up, the jaws relax, the piston down, the jaws automatically bite the coupling with the piston to do the circular motion of the downlink, in order to achieve the purpose of unloading the thread. The main purpose is to dismantle the deep well pump Packers, and other downhole tools that are threaded together.
