Hydraulic drive works: the oil as a working medium, relying on changes in the volume of the seal to convey the movement, relying on the pressure inside the oil to transmit power. In fact, the hydraulic drive is an energy conversion device which converts the mechanical energy into a hydraulic energy for easy transport and then converts the hydraulic energy into mechanical energy to drive the working mechanism to complete the required action.
Hydraulic drive structure: hydraulic chuck mainly consists of the cylinder, piston, ring, support sets, kava blocks, disc springs, kava, protective cover, protective cover, thrust ball bearings, seals and other parts and standard components.
Hydraulic chuck works is the work of hydraulic oil from the tank into the fuel tank into the cylinder, the cylinder and the piston constitutes a closed chamber, with the pressure increases, under the action of pressure oil, the piston down, the thrust ball bearing push card Circle, support sets together down, so that the disc spring is compressed, the collar in the downward movement at the same time driving the three kava to leave the center of the horizontal movement, so as to achieve the purpose of releasing the drill pipe.
Need to clamp the drill pipe, the operation of the valve to open the control valve, the chuck closed cavity of the oil by the tubing, hydraulic check valve and valve and the mailbox connected, then closed chamber without pressure, Spring in the role of elastic force, automatically reset, and to promote the support sleeve, collar, thrust ball bearings and piston up to move, driving the three kava to the horizontal movement, so as to achieve the role of clamping the drill pipe.
