SL-TA Self-resetting Bolt Tensioner

The working principle of bolt stretcher is mainly based on hydraulic transmission, using the Pascal principle to transfer energy. twelve The bolt stretcher applies direct external force to the bolt through a hydraulic cylinder, causing it to be stretched within the elastic deformation zone. This stretching causes slight deformation of the bolt diameter, making it easier for the nut to loosen. During the operation, the design of the hydraulic tensioner allows multiple bolts to be tightened and disassembled at fixed values simultaneously, ensuring even force distribution. This method is not affected by bolt lubrication and thread friction, thus providing more accurate bolt load control. In addition, the design of hydraulic stretchers also takes into account the requirements of usage space and bolt exposed length to ensure correct use. When using, it is necessary to calculate the set tensile force based on the pre tightening force requirements of the bolt and ensure that it does not exceed the allowable stress of the bolt. For multiple bolts on the flange surface, it may be necessary to stretch them in stages and in order to avoid uneven tensile force between bolts.

High-Quality Self-reset Bolt Stretcher for Purchase

Bolt tensioner is the abbreviation of bolt hydraulic tensioner, hydraulic tensioner, which with the help of hydraulic boost pump (ultra-high-pressure hydraulic pump) to provide a hydraulic source, according to the tensile strength of the material, yield coefficient and elongation to determine the tensile force, the use of ultra-high-pressure pumps generated by the tensile force, so that the bolt is applied force in its elastic deformation zone is stretched, the diameter of the bolt slightly deformed, so as to make it easy for the nut to loosen, and in addition also can be used as a Hydraulic interference connection applying axial force for top pressure installation. The biggest advantage of the tensioner can make a number of bolts at the same time be fixed tightening and dismantling, cloth force is uniform, is a safe, efficient, fast tool is the best way to tighten and dismantle a variety of specifications of the bolt. It is used in petrochemical, nuclear power, wind power, hydropower, thermal power, ship, railway, aerospace, mining, heavy machinery and other fields. According to different working conditions application conditions and user requirements, special tensioner design can be made.
