The key point of high quality of the most representative bolt tensioner!Air hacksaw company

　　The company (Company) bolt (composition: head and screw) tensioner is mainly used for the fixed value fastening and disassembly of various specifications (specifications) bolts, using the tension generated by the ultra-high pressure oil pump (Deep well pump) (explanation) : The mutual traction force when the object is under tension), so that the applied bolt is elongated in its elastic deformation zone, and the bolt diameter is slightly deformed, so that the nut is easy to loosen. In addition, it can also be applied as a hydraulic (hydraulic) interference connection. Axial force device for top pressure installation. The biggest advantage of the tensioner is that multiple bolts can be fastened and disassembled at the same time. The distribution force is uniform (jūn yún), which is safe and efficient (referring to high efficiency) , Fast (meaning: fast and agile) tools. The hydraulic wrench transmits power to the working head through the high-pressure oil pipe and the hydraulic pump, which drives the working head to tighten or loosen the nut. The hydraulic pump can be driven by electricity or compressed air. The working head of the hydraulic wrench is mainly composed of three parts, the frame (also called the shell), the oil cylinder and the transmission parts. The output force of the oil cylinder, the piston rod of the oil cylinder and the transmission part form a motion pair. The distance from the center of the oil cylinder to the center of the transmission component is the hydraulic wrench amplification arm. The oil cylinder output multiplied by the arm is the theoretical output torque of the hydraulic wrench. The actual output torque is smaller than the theoretical output torque. The THA series of ordinary hydraulic tensioners are suitable for the tensioning of single-size bolts. Due to the use of a high-precision (precision) sensor (transducer) (0.3% deviation) to detect the pressure and the microcomputer processing (chǔ lǐ) to control the start and stop of the stretcher pumping station, ensuring the tensile force of the stretcher (tensile pull) High-precision output, tensile force output error ≤±1%. This revolutionary achievement has won a national patent (meaning: open letters or public documents), breaking through that similar products can only achieve an output accuracy of ±5%. Due to the direct digital preset of the stretching force value, which is stored in the chip (also called microcircuit), the stretcher will alarm when the stretcher reaches the required stretching force, and will automatically stop, and the stretcher will automatically reset at the same time. Absolutely avoid the occurrence of over-travel and overload accidents of the stretcher. A start-stop switch is installed on the working head of the stretcher, so that the stretcher can be started and stopped directly on the working head, which is easy to operate and control. A set of stretcher only needs one person to operate and control, and it is especially suitable for long-distance high-altitude operations.
