Main operation method of hydraulic nut

The hydraulic nut is composed of a nut body, a pressure ring, an oil filling port and an oil drain and exhaust joint. The appearance of the nut is cleaned when using it. Screw the nut into the workpiece and lock the nut. The pressure ring should be in the original position. Then insert the oil injection hose interface of the hand pump into the oil injection port, lock the handle of the unloading switch on the right side of the hand pump, slowly pressurize, and drain the oil at the same time The bleed cap on the upper part of the vent connector is rotated inward and deflated until the air in the nut is drained. After the clean hydraulic oil flows out, the bleed cap is loosened outward to close the one-way valve and continue to pressurize the oil to make the pressure ring Press out to achieve the purpose of compaction, until the pressure reaches your desired compaction purpose. Loosen the handle of the unloading switch and loosen the pressure hose joint of the hand pump. (Guide: Determination of screw tightening torque during assembly)

　　The manual pump is filled with hydraulic oil before use. The oil filling port is at the back end of the manual pump. Open the nut to fill the oil, and lock it after filling. When pressurizing, press the handle on the top of the pump up and down, and lock the handle of the unloading switch on the right side of the pump clockwise; when depressurizing, turn the handle counterclockwise. Connect the pressure gauge on the left side to observe the pressure indication during pressurization, and connect the oil injection hose to the front end of the hand pump.
