The hydraulic nut is an advanced bolt assembly method, which isespecially suitable for the mechanical fastening of narrow space and heavy load vibration. The working principle of the hydraulic nut is to use the hydraulic cylinder to directly apply external force to the bolt, so that the bolt to be applied is stretched in its elastic deformation zone. After the bolt is stretched, tighten the lock ring on the hydraulic nut, so that the bolt will be locked in the stretched position by the lock ring.
1.Due to the use of an ultra-high pressure hydraulic system, the size of the hydraulic bolts matches the originaltraditional nuts, and there is no need to modifytheoriginal bolt pair design.
2.There is no need for wrench and socket space, and the size of the bolt pair is more compact.
3. The screw operates in a pure tensile state, and the same size screw can provide more than 20% -30% output contribution, making the bolt pair safer.
4. By hydraulically stretching the bolts, the predetermined load is more accurate and the tightening is more reliable
5. Adopting the most advanced polyurethane/metal composite sealing structure in the world, the overall sealing structure has fewer sealing components, and the sealing form takes into account low pressure, high pressure, and ultra-high pressure sealing, especially suitable for working under ultra-high pressure conditions.
6. The oil cylinder has good operating stiffness, stable and reliable operation, and is easy to operate
7. When the piston exceeds its stroke, the system automatically releases pressure, and the operator’s mistake can be effectively corrected by the system.
