The heavy workload of the operator in the process of well repair is to put on and unload the oil pipeline tools and drilling tools of the silk buckle, in the past has been using pipe pliers or chain pliers, not only the labour intensity is large, but also has the danger. Hydraulic power pliers are the mechanical tools for uploading and unloading the wire fasteners operated by the power of the well dressing machine, which can reduce the labour intensity of the well dressing workers and avoid or reduce the occurrence of injury accidents. At the same time, the hydraulic power clamp enhances the torque of the wire fastening of the tubing and drilling tools, and reduces the occurrence of tubing and drilling tool debuckling accidents. The working principle of the hydraulic power tongs is to transfer the power of the well dressing machine to the hydraulic motor of the hydraulic power tongs through the stroke reducer, and then through two or one level of deceleration, so that the tongs open gear rotation, resulting in two kinds of high and low rotational speeds, so as to drive the tubular tools (drilling tools) to rotate. When the open gear rotates, its pallet frame does not rotate under the braking effect of the brake hammer, so that there is a relative motion between the open gear and the pallet frame. In this way, the two rollers of the palate plate will climb on the slope plate and force the jaws on the crotch plate to move towards the centre of the pipe tool (drilling tool) until they bite into the pipe tool (drilling tool), and then drive the pipe tool (drilling tool) to rotate together with the opening gear.
Hydraulic power tongs product features:
1, torque control system integrated in the power tongs torque control precision;
2、Intelligent control of rotational speed;
3, automatic identification of forward and reverse rotation;
4, on-site real-time viewing on the buckle torque curve;
5, can be made of flexible materials with large contact area clamp teeth, reduce the damage to the surface of the oil pipe;
6, optional speed control function valve group.
