What are the advantageous features of hydraulic power tongs?

Hydraulic power tongs is a kind of open type power tongs, which is a special equipment for loading and unloading pumping rods, tubing, small drilling rods and small casing threads in oilfield well repairing operation.

The hydraulic power tongs are driven by a low-speed, high-torque cycloidal oil motor, and the manual reversing valve is directly matched with the motor. The hydraulic power clamp has a simple and compact structure, and is a lightweight, flexible and reliable hydraulic power clamp for tubing in the hydraulic power clamp for well repair.

Hydraulic power tongs have the following advantages:

1、Hydraulic power tongs and the main clamp with the composition of the combined clamp, operation of the main clamp on the manual reversing valve, synchronized automatic tightening or loosening of the oil pipe.

2, the chuck of the main clamp and the rear clamp is a two-way clamping mechanism, the inner curved roller climbs upward. Just rotate the steering gear on the main clamp and rear clamp by 180 degrees to change the clamping direction.

3、According to user needs, the power clamp can also be equipped with a safe valve, in the oil supply system safety valve failure to play the role of overload protection.

4、The opening of the clamp head is equipped with automatic opening and closing of the protective door, and the workshop plays a safe and protective role.

5, adjust the oil supply pressure, in order to obtain the required tightening torque of various materials oil pipe.

The working principle of the hydraulic power clamp is to transfer the power of the well dressing machine to the hydraulic motor of the hydraulic power clamp, through the stroke reducer, and then through the two-stage or one-stage deceleration, so that the open gear clamp head rotates to produce high speed and low speed, so as to drive the drilling tool (drilling tool) rotation.
