| Gas-liquid pressurized cylinders work quickly | Cixin pressurized cylinder is pressurized cylinder by, cylinder, fast into the cylinder and tank, the reason is not using liquid of compressibility, According to the balance of power: A1P1 = A2P2, (A1, P1; the piston area and A2, under pressure; the small piston area and P2 by pressure), Two area of piston fixed together, its ends for: P1 / than pressure P2 = A2 / A1, Using compressed air pushes the piston, piston small proportion of liquid and close the high-pressure liquid output, high-pressure liquid cylinder piston utility to achieve the pressurized on purpose. The working procedure can be explained as the following three phases:
1 and rapid development stages: in the mouth cavity cylinder C the compressed air, fast and solid coupling of piston mobilization pressurized cylinder piston to advance rapidly, the workpiece subarachnoid D mouth connected air. While the cavity through pressurization cylinder valve from oil to fuel oil cylinder quickly on oil cylinder subarachnoid cavity, return the tank. Until the workpiece, the piston rod contact with resistance to thrust into the balance, fast and pressure cylinder to stop.
2 and pressurized work into phases: when the cylinder quickly into the thrust forward, not A pressurized cylinder start up time cavity compressed air, the pistons general mobilization and solid connected to the pressurized turbocharged piston cylinder into its mouth and inferior vena B, connected to the air, While cutting oil cylinder valve and the turbo tank, make them no longer connected. Pressurized cylinders in liquid at the booster, plunger, its volume sends his misfortune occurred, volume oil pressure rising proportion, Utility in pressurization piston thereby pressurization cylinder of greater power output, and quickly into the cylinder piston work together, until turbocharged into the job requirement.
3, fast reduction stage: pressurization work in this matter, and in the mouth and pressurized cylinder D time cylinder of inferior vena B mouth simultaneous compressed air, two cylinders on A, C mouth cavity through the air, pressure cylinder quickly changed: While oil cylinder valve connected with tanks, pressurized cylinder piston in fast into the mobilization under the oil cylinder, turbo, subarachnoid cavity platoon until the oil cylinder. To this, the hydraulic and pneumatic supercharging cylinder of a job this course, from next process repeated.
Supplement: pressurization trip to production needs, regulators: pressurization can be a cavity in parallel, travel by adjusting the regulator volume regulator, to transform work, adjusting range from 0 to the master schedule for 20mm. According to the truth of the liquid compressibility V1 = V2 not to.
