Operation of Hydraulic Stretcher, Operate the ultra-high pressure oil pump, input the high pressure oil to the cylinder of the hydraulic stretcher, the piston starts to work, and the hydraulic stretcher enters the working state. At this time, attention should be paid to the working pressure of the ultra-high pressure oil pump and the stretching length of the hydraulic stretcher, and it must be controlled within the set range.

When the working pressure and drawing length of the hydraulic stretcher reach the rated value, the ultra-high pressure oil pump should stop working immediately, insert the dialing handle into the dialing hole of the round nut, and pull the round nut firmly in place clockwise.
In the operation of hydraulic stretcher, the process requires to continue stretching to increase the elongation length. After the round nut is tightened in place, the ultra-high pressure oil pump should relieve pressure according to the operation procedure, and then insert the dialing handle into the piston dialing hole of the hydraulic stretcher, and dial the handle to make the piston reset. Then operate according to the above method until the process requirements are met.
