Super high pressure high-flow telescopic oil pipe follow-up oil delivering method

Abstract

The invention relates to a super high pressure high-flow telescopic oil pipe follow-up oil delivering method. The super high pressure high-flow telescopic oil pipe follow-up oil delivering method comprises the steps that a telescopic oil pipe, an upper end valve block and a lower end valve block are manufactured respectively, then the telescopic oil pipe conducts follow-up oil delivering, the upper end valve block is connected with an oil pipe cylinder, oil fills the oil pipe cylinder through a liquid filling valve, a high pressure flange is communicated with high pressure oil liquid, oil liquid pressure is increased by inputting the pressure oil liquid into the oil pipe cylinder through the valve blocks, the oil pipe cylinder is connected with a supporting block and is fixed to a hydraulic machine rack, an oil pipe piston is fixed to the lower valve block through a piston press ring, the lower end valve block and a hydraulic machine movable cross beam conduct follow-up motion, the high pressure oil liquid fills the oil pipe cylinder from the upper end valve block and is delivered to the lower end valve block through a hollow piston oil pipe in the oil pipe cylinder, and the oil liquid is delivered to the oil pipe movable cross beam fixed to the rack through follow-up motion of a hydraulic cylinder. The limit of pressure resistance of the oil liquid of a high pressure hose is broken through, the telescopic oil pipe is large in oil delivery capacity and small in occupied space, requirements of quick liquid filling and pressure increasing of a super high pressure hydraulic machine are met, the work efficiency of the hydraulic machine is improved, the universality is high, the applicable range is wide, and the safety degree is high.

Description

technical field [0001] The invention relates to the technical field of ultra-high-pressure large-scale hydraulic equipment, in particular to an ultra-high-pressure large-flow telescopic oil pipe follow-up oil delivery method. Background technique [0002] Large-scale hydraulic equipment is a kind of equipment that uses liquid as the working medium and is extruded by hydrostatic pressure. The mechanical body of the hydraulic press is mainly composed of column archway, hydraulic cylinder, movable beam, mobile workbench and other parts. Among them, the hydraulic cylinder is the key power device of the hydraulic equipment. According to the requirements of different equipment, the hydraulic cylinder is mostly installed in the fixed beam of the press, the movable beam and the mobile workbench. The tube follows the oil delivery, the pressure resistance of the high-pressure hose is limited, the wall thickness of the tube is large, the bending radius is large, the use space is limit...

Among them, the hydraulic cylinder is the key power device of the hydraulic equipment. According to the requirements of different equipment, the hydraulic cylinder is mostly installed in the fixed beam of the press, the movable beam and the mobile workbench. The tube follows the oil delivery, the pressure resistance of the high-pressure hose is limited, the wall thickness of the tube is large, the bending radius is large, the use space is limited, the oil delivery flow is low, and the working efficiency of the hydraulic cylinder is reduced, so it cannot be widely used in large-scale hydraulic equipment with ultra-high pressure and large flow
