The principle and function of hydraulic bolt tensioner
source:Industry News release time:2022-08-15 Article author:yu Popular:Air band saw
The hydraulic bolt tensioner is used on the bolts by the pulling force generated by the manual or electric high-pressure pump, so that the bolts are elongated in the elastic bending area, the diameter of the bolts is slightly reduced, and the nuts can be easily screwed to the bottom. After the tensioner is unloaded That is, the tightening work is completed, otherwise, the nut can be easily removed, and the thread of the bolt pair is not damaged and the pulling force is accurate. It is a safe, efficient and convenient bolt tightening and dismantling tool.
Bolt tensioners are widely used in the bolt removal and locking of different types of equipment in all walks of life, solving many problems in bolt removal and locking for customers. Practice has proved that our company's bolt tensioners meet the needs of customers in different working conditions.
Principle of hydraulic bolt tensioner
It uses the hydraulic source provided by the hydraulic booster pump (ultra-high-pressure oil pump) to directly exert external force on the bolt end and uses the tensile force generated by the ultra-high-pressure oil pump to stretch the bolt to the required length, and the diameter of the bolt is slightly deformed, so that the nut is easy to Loosening, since it is not affected by the lubrication effect of the bolt and the friction of the thread, the tensile method can obtain a more accurate bolt load.
In addition, it can also be used as a device for applying axial force for hydraulic interference connection to perform top pressure installation. It is a safe, efficient and fast tool and the best way to tighten and remove bolts of various specifications.
Hydraulic bolt tensioner
The biggest advantage of the tensioner is that multiple bolts can be tightened and disassembled at the same time, and the force is evenly distributed. It is a safe, efficient and fast tool. It is the best way to tighten and disassemble bolts of various specifications. Used in petrochemical, nuclear power, wind power, hydropower, thermal power, ships, railways, aerospace, mining, heavy machinery and other fields. According to different working conditions, application conditions and user requirements, special tensioner designs can be made.
