Wireline Pressure Control Wireline Hay Pulley
I. Introduction:
The ground pulley is used to pull the steel wire or cable (wire
rope) from the top of the blowout pipe to the steel wire or cable
drum plane, so that the pulling force of the steel wire or cable
(wire rope) is moved from the vertex to the Christmas tree, thereby
reducing the steel wire or cable (wire rope) The side tension load
prevents the blowout pipe from being bent and damaged. You can also
lift the ground pulley to change the load direction of the steel
wire or cable (wire rope).
II. Technical parameters:
1. Applicable steel wire specification: 0.16";
2. Pulley specification: 16";
3. Safety load: 20KN (2.0 tons).
III. How to use:
1. After connecting the ground pulley to the tension meter
(referring to the weight meter), connect it to the well head with a
rope. Adjust the rope length according to the position of the winch
drum to make the wire as parallel as possible to the drum plane
(that is, the angle between the wire coming down from the top of
the blowout pipe and the wire going out of the drum is
approximately 90 degrees);
If the ground pulley is hoisted to change the load direction of the
steel wire or cable (wire rope), directly use the hook to pass
through the hoisting ring to hoist the pulley;
2. Unscrew the compression nut on the pulley bracket, and unscrew
the lock block counterclockwise to expose the groove on the pulley
bracket;
3. The steel wire or cable (wire rope) is inserted into the pulley
groove through the pulley bracket groove;
4. Rotate the lock block 90° clockwise, and then tighten the
compression nut.
IV. matters needing attention:
1. Before use, check the wear of the anti-hopping block on the
carrier to ensure that the steel wire or cable (wire rope) does not
jump out of the wheel groove;
2. When storing, it is strictly forbidden to hit the pulley with
heavy objects to avoid deformation;
3. The specifications of the ground pulley should be selected
according to the diameter of the steel wire or cable (steel rope),
so as to avoid excessive bending of the steel wire or cable (steel
rope) and fatigue damage;
4. When the ground pulley is used in conjunction with the floor
stand, it can prevent the steel wire from instantaneous relaxation
and impact on the pulley.
