Working principle of crushing hammer

When change valve bottom right absorption, hydraulic oil inlet from the lower end of the piston rod, under the action of fluid pressure, piston rod up and cavity on the piston rod of hydraulic oil from the oil outlet flow in the body, in the process of the piston rod up nitrogen chamber is compressed nitrogen, nitrogen pressure, at the same time, the accumulator and the inlet of the bottom unicom, accumulator energy storage at the same time, Until the accumulator pressure equalizes with the inlet pressure.

When the piston rod upward to travel peak, upper and change valve, inlet hydraulic oil from the top of the piston rod, under the action of fluid pressure, piston rod down, at the same time on the compression of the top surface of the piston rod and the nitrogen chamber high pressure nitrogen gas, in addition, the piston rod of the hydraulic oil is flowing to the piston rod inside inferior vena cavity, this is equivalent to fast forward, When the piston rod contacts the brazing rod, the high speed impact of the piston rod and the force of hydraulic and compressed nitrogen act on the brazing rod at the same time, so that the brazing rod produces instantaneous explosive force, so as to be indestructible.
