Working principle of hydraulic nut

In the 1990s, the traditional nuts could not meet the fastening requirements in the field of heavy machinery. As a result, a new type of powerful fastening element-hydraulic nut appeared abroad. Hydraulic nut is a common part of steel machinery, which is often used to disassemble bolts, pre-tighten bolts and lock mechanical workpieces. The working principle of hydraulic nut is to use the piston thrust generated by high-pressure oil pump driving hydraulic oil to complete the installation and disassembly of shaft. Using hydraulic nuts can not only speed up the working time, but also improve the installation accuracy and disassembly safety.

Hydraulic nut is a detachable tool, which is widely used in interface locking of large machinery. Its shape is usually circular or conical, which is very suitable for specific workpieces. The basic working principle of hydraulic nut is to inject hydraulic oil into the nut to generate strong pressure, thus pushing the piston and making the installation and disassembly of the workpiece more convenient. Using hydraulic nut is a safe and non-wasteful method, which promotes the development of industrial production.
