Abstract
A device is proposed for controlling a hydraulic lifter which includes a throttling valve, two servocylinders with pistons and profile feeler mechanism. In order to improve reliability of automatic lowering of the well pipe string according to the assigned law and to simplify the design, the throttle valve is made in the form of a cylinder with openings and slide valve. The device is equipped with an end switch and a float located on the outer surface of the cylinder. The lower cavity of the throttling valve by means of the pipeline with valve is connected to the cavity of the servocylinder, while the float is installed with possibility of interacting with the end switch which is connected to the pipeline valve.
