The invention provides a split type
plunger steel wire liquid draining device. The split type
plunger steel wire liquid draining device is divided into an upper part and a lower part, wherein the upper part comprises a steel
wire rope connector, an upper weighing rod, an upper
sieve pipe, a
damper and a lower
sieve pipe which are sequentially in threaded connection from top to bottom; the lower part comprises a wing ring, a linkage rod, a
plunger and a lower weighing rod, the upper end of the linkage rod penetrates through the wing ring and is connected with the lower
sieve pipe, the plunger comprises a plunger sleeve and a plunger rod, the lower ends of the plunger sleeve and the plunger rod are connected and sealed, the lower end of the linkage rod is inserted into the plunger sleeve and is connected with the upper end of the plunger rod, the lower end of the plunger rod is connected with the lower weighing rod, the outer
diameter of the plunger sleeve is smaller than the inner
diameter of an oil tube, and the density of the plunger sleeve is smaller than that of the lower weighing rod. According to the split type plunger steel wire liquid draining device, the plunger is driven through a steel
wire rope, so that a user does not need to be consider whether the energy in a well is sufficient, and the plunger is unlikely to be blocked; by virtue of the
damper, the phenomena of twisting and bending of the steel
wire rope caused by the upward movement accelerated by relatively
high pressure in the well are effectively prevented, and the service life of the steel wire
rope is guaranteed; the liquid draining efficiency is high, and accumulated liquid at the bottom of the well can be thoroughly eliminated.
