| Gas-liquid pressurized cylinder overview and principle | Gas-liquid pressurized cylinder overview and principle
Keywords: hydraulic and pneumatic supercharging cylinder, The cylinder, Working principle
Along with the development of modern industrial automation, stamping, molding parts more to realize the stamping or injection molding must have an output force big part to squeeze metal, rubber or plastic. Because single hydraulic and pneumatic supercharging cylinder speed control, not in load changes greatly circumstance, vulnerable to crawl, "or" from "go" phenomenon. Although the pressurization system and hydraulic power output has characteristics, but need a independent motor and oil pump, valve, E-mail, etc. Of the components of hydraulic tube, the high cost of manufacture hydraulic power, and noise. Leakage and oil temperature control system in hydraulic booster driving system is difficult to solve, industrial demand. According to the gas and liquid pressurization cylinder of fluid mechanics and pneumatic, hydraulic principle of pneumatic transmission and hydraulic transmission synthesis principle of pneumatic transmission and hydraulic transmission comprehensive advantages of using the incompressible fluid, with force equilibrium theory, through the input low pressure obtain larger output force. Meet the metal, such as rolling rivetting plank, extrusion of various container etc request.
The gas and liquid pressurization cylinder structure theory
Gas-liquid pressurized cylinder, mainly by oil cylinder cylinder B and convert cylinder composed C. Cylinder B is the common after buffer, the piston and cylinder, piston rod area ratio of the area is pressurized cylinder of gas and liquid pressurization than beta, beta = piston area/piston area = D2 / d (D2, d B piston cylinder respectively with the diameter of piston rod B (A1). In connection with oil cylinder lid D A, B and convert cylinder cylinder C, in order to prevent the hydraulic oil and gas, the internal mutual string of groove design of high machining accuracy, the reasonable selection of seals. Seal performance for the purpose of the cover, the main consideration wear-resisting sealing seal, so choose, B32028 type polyurethane P5008 park circle, For the cover of the sealing performance is better, the seals and sealing is dependent on its YX form in the open lips tightly sealed surface and keep good sealing, sealed performance, less friction, compression performance and working stability, long service life, when used alone, so don't roll in the selection of the sealing side cover sealing, guarantee the YX gas cylinders to cover a string of not mixed with oil. When installed, piston B in the left with no more than the length of the cover in connection with the cylinder cover the hole is advisable, guarantee the hydraulic oil cylinder of A covered by entering the gas-liquid piston cylinder C convert into Detroit piston and A2 A3 two parts. Cylinder, due to the selection of gas-liquid convert cylinder C under high pressure, need strength than oil cylinder and cylinder, so B gas-liquid convert cylinder C chose intensity of 20 steel, Since A major oil cylinder storage, cylinder pressure cylinder diamethe B, small, cylinder of A and B strength requirement is not high, so choose materials for A6063D - T5 steel. Gas-liquid pressurized cylinders using pure barometric pressure, low proportion of product will improve several times supply gas-liquid convert cylinder C using the pressurization. |
