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.
