Advantages of Hydraulic Power Tong
Reduce labor intensity: Hydraulic power tongs use the power of the well dressing machine to work and mechanically unload the threads, which greatly reduces the labor intensity of the well dressing workers and avoids or reduces the occurrence of injury accidents.
Improve safety and efficiency: Hydraulic power tongs reduce the occurrence of accidents of starting and stopping the drilling of tubing and drilling tools by increasing the torque of tubing and drilling tool threads, thus improving the safety of the operation.
Improve productivity: The working principle of hydraulic power vise is to transfer the power from the well dressing machine to the hydraulic motor of the hydraulic power vise, and make the vise head open gear rotate through the stroke reducer to produce high and low rotational speeds, so as to drive the tubular column (drilling tools) to rotate. This design improves productivity and saves 30%-200% of machining and clamping time in mass production cycle.
Ensure machining accuracy: The hydraulic fixture is used for mounting and positioning, which can quickly and accurately determine the relative position between the workpiece and the machine tool and cutting tool to ensure the machining accuracy and continuous stability. The high hardness jaws and jaw bodies combined with high precision machining technology make the repeatability precision reach 0.02mm, parallel precision reach 0.02mm and vertical precision within 0.02mm.
Universality and flexibility: The vise base of the hydraulic power vise can be arbitrarily combined with a series of modular jaws of different standardized designs, functions and specifications to realize the machining of workpieces of various sizes and specifications, effectively improving productivity and reducing loading and unloading time.
Adapt to special working environment: Hydraulic power vise is simple to operate, easy to replace and has a long service life. The cutter is bolted for easy disassembly and replacement. In addition, its optimized dynamic design makes it powerful and increases the effective working time.
Safety protection measures: The opening of the clamp head is equipped with an automatic opening and closing safety door, which plays a role of safety protection when working. According to user needs, the power vise can also be equipped with a relief valve and a special torque pressure gauge, real-time monitoring of the torque output of the power vise, in the hydraulic system pressure is higher than the rated pressure of the power vise or the hydraulic system relief valve fails to play a role in overload protection.
Preparation before operation

Hydraulic Power Tongs Common Faults And Solutions
High gear pressure can not go up
The cause of the failure may include oil falling into the high gear air tire, resulting in a failure to hold, or a problem with the hydraulic system (e.g., a malfunctioning upper threaded relief valve). The solution includes removing the oil from the friction plate of the air tire and adjusting or replacing the relief valve.
Low gear pressure can not go up (thread can not be unloaded)
The cause of the malfunction may include: the low gear tire friction plate is seriously worn, can not hold; low gear tire friction plate is stained with oil; low gear airbag separation is not clear; the big brake belt is too loose. Solutions include replacing the low gear friction plate, removing oil contamination, making sure the oil volume is sufficient, and adjusting the tightness of the big brake belt.
High gear idling (pressure is not high)
The cause of the problem may include the brake band being too tight or poorly lubricated. The solution includes adjusting the length of the brake band and strengthening the lubrication.
Hydraulic clamp oil leakage fault
Hydraulic clamp oil leakage is a common type of malfunction that may be caused by aging, wear or deformation of seals. Oil leakage may damage other parts of the hydraulic clamp, affecting work efficiency and safety. To deal with hydraulic clamp oil leakage, you can replace the seals or repair the sealing surface.
Hydraulic tongs do not work properly
Hydraulic tongs can not work properly due to a variety of reasons, such as oil line blockage, insufficient oil delivery pressure, electronic control components failure. The solution includes checking and clearing the oil circuit, adjusting the pressure, and replacing the faulty components.
Hydraulic clamp jammed or stuck
Hydraulic clamp jamming or seizing may be caused by operation error, damaged components, hydraulic cylinder leakage and other problems. Treatment includes correct operation and replacement of damaged parts.
Excessive operating noise of hydraulic tongs
Excessive operating noise of the hydraulic tongs may pose a threat to the health and safety of the operator. This is a common type of fault, due to air into the system, excessive air bubbles in the hydraulic system or high pressure, or due to the failure of some components in the system, such as aging rubber gasket, serious wear of the pins, and so on. Solutions include removing air and air bubbles, reducing pressure, and repairing faulty components in the system.
Hydraulic tongs not holding pressure
Failure of the hydraulic clamp to hold pressure can also be caused by oil leaks, worn seals, air in the system, etc. Treatments include replacing seals, checking and terminating oil lines, and removing air bubbles from the system.
Structural Features of Hydraulic Power Tong
• The hydraulic power tong is driven by a low-speed, high-torque hydraulic motor. This design allows the clamp to generate high clamping forces for applications requiring high torque.
• The vise head utilizes a bi-directional clamping mechanism with an internally curved roller climbing mechanism. This design allows the clamp to hold a wide range of pipe diameters tightly while being simple to operate and easy to maintain.
The large clamp is equipped with an automatic opening and closing safety gate, which provides protection during operation and improves operational safety.
• The hydraulic power tong can be directly connected with the power of the well dressing machine, and the power is transmitted through the hydraulic system to realize the quick clamping and loosening of the clamp, so as to improve the working efficiency.
• The clamp is equipped with a safety valve and a special torque pressure gauge to provide protection and monitoring when the system pressure is too high or when the torque output needs to be monitored.
• Hydraulic power tongs are designed with a safety pressure relief device. When the pressure reaches the set value, an audible warning is issued and the action is stopped to prevent accidents.
