The utlity model has following advantage: use because oil cylinder adopts common low pressure source only to make the low pressure oil cylinder, high-pressure system is realized by plunger pump, thereby need not oil cylinder is carried out enhancement process, making its compact structure, volume is little, cost is low, power consumption is little, noise is low, supercharging efficient height; The low pressure input can be gas and also can be liquid, is widely used.
Description of drawings
Fig. 1 is a structural principle schematic representation of the present utility model.
Embodiment
The utility model is designed for waterpower cutting or water swelling device, bidirectional piston 2 and seal ring 29 thereof are housed in the oil cylinder 1, therefore this mechanism is the symmetrical configuration of the benchmark left and right sides with the middle vertical plane of piston 2, serves as main to working principle narration of the present utility model below in conjunction with accompanying drawing with the structure in left side.
The solid seat in oil cylinder 1 two ends is in left and right sides cylinder seat, cylinder seat 3 is shaped in low pressure oil-feed duct 31 and the cylinder and communicates, cylinder seat 3 is axially installed with plunges pump body 4 respectively, the coaxial in opposite directions axial center hole that is installed in piston 2 of plunger 21 of the hollow structure that is slidingly matched with the plunges pump body inwall; The middle part, cylndrical surface of piston 2 is shaped on annular groove 27 and radial direction through hole 28, and radial direction through hole 28 is communicated with annular groove 27 with the axial center hole of piston, and plunger 21 afterbody portions have through hole 24, also are that radial direction through hole 28 is communicated with annular groove 27 with plunger cavity.The tube wall of plunger 21 also has small through hole 25, and cylinder seat bottom surface, the left and right sides is shaped on the draining hole 32 that communicates with the port of plunges pump body 4 respectively, and annular groove 27 is communicated with draining hole 32.The inwall of plunges pump body 4 is embedded with oil-containing lining 44.Left and right sides pump cover 7 is shaped on radially low pressure water inlet duct 73 and axially high pressure water outlet duct 71 respectively, and axially high pressure water outlet duct 71 is connected with high-voltage tube by high-pressure pipe connector 72.Valve piece 6 edges are fixed in the inner of pump cover 7, be shaped on the low pressure duct 61 and the high pressure duct 62 of mutual isolation in the valve piece 6, low pressure duct 61 1 ends are communicated with the radially low pressure water inlet duct 73 of pump cover, the other end is communicated with plunges pump body apical pore 42 by one-way valve 5, high pressure duct 62 1 ends are communicated with axial high pressure water outlet duct 71 by one-way valve 8, and the other end is communicated with plunges pump body apical pore 42.
