Working principle of hydraulic stretching machine

Hydraulic stretching machine is the use of hydraulic principle, adopts the hydraulic oil to drive the movement of the piston to work, the hydraulic cylinder directly on the bolt force is applied, is applied force of bolts in the elastic deformation region are elongated, bolt diameter micro deformation so that nut easy to loose.

The work of hydraulic stretching machine hydraulic press machine manufacturers is gentle static pressure, which is mainly used for the fixed value fastening and disassembly of various kinds of bolts.

Some users reflect the speed of hydraulic machine is slow, and that how to improve speed? Simple explanation, hydraulic tensile machines have entered will fast forward, fast forward is the full flow of hydraulic pump, industry and trade into the start control valve or the balance valves and other components, pressure balance valve needs and system about debugging, make sure reasonable pressure difference.
