The hydraulic bolt tensioner uses the hydraulic source provided by the hydraulic booster pump (ultra-high pressure oil pump), determines the tensile force according to the tensile strength, yield coefficient and elongation of the material, and uses the tension produced by the ultra-high pressure oil pump to make the applied bolt stretched in its elastic deformation zone and the diameter of the bolt slightly deformed, so that the nut is easy to loosen, and can also be used as a hydraulic interference. Connecting the device to exert axial force and installing under top pressure, the greatest advantage of the stretcher is that it can make multiple bolts fastened and disassembled at the same time with fixed value and uniform cloth force. It is a safe, efficient and fast tool and the best way to fasten and disassemble bolts of various specifications.

Hydraulic bolt Tensioner is referred to as hydraulic stretcher. The function of its power element is to convert the mechanical energy of the prime mover into the pressure energy of the liquid. It refers to the oil pump in the hydraulic system, which provides power to the hydraulic bolt stretcher to realize the conversion of the hydraulic pump to the mechanical energy. The function of the power element of the hydraulic bolt stretcher is to convert the mechanical energy of the prime mover into the pressure energy of the liquid, referring to the oil pump in the hydraulic system, which provides power to the whole hydraulic system.
Application of hydraulic bolt Tensioner: electric power, shipbuilding industry, metallurgical coal mine, petrochemical industry, heavy machinery and other fields.
