State shown in the figure is the original state of simulated automotive, i.e. static, the state of blowing out under the room temperature.Its principle of work and process are:
At first on PLC controller 4 operation interfaces, can see real-time air pressure, parameter values such as temperature and rotating speed.Air pressure at first is set, select automatic or manual operation, for the ease of introducing, here with the manual operation example: at first by selecting cylinder to descend, select pressurization then, then hydraulic drive container upper cover 6 along slide bar 7 slow descend and with a bigger pressure with itself and pressure vessel 8 compactings, with the assurance impermeability.And the topworks of this operation is a pneumohydraulic pressure-cylinder 1.
Pneumohydraulic pressure-cylinder 1 is by pressurized cylinder, pressurizing cylinder, and fast inlet casing and fuel tank are formed.Its principle is to utilize the incompressibility of liquid and according to the equilibrium of forces principle, the piston that two areas are not waited connects firmly together, promote the big piston end with pressurized air, the just proportional output highly pressurised liquid of liquid of valve piston end sealing, thus highly pressurised liquid acts on the purpose that reaches supercharging and reinforcing on the oil cylinder piston.
Its working routine can briefly be illustrated as following three phases:
1, the quick propulsion phase: feed pressurized air at the F.F. upper chamber of air cylinder, the F.F. piston drives the pressurizing cylinder piston that connects firmly with it and advances to workpiece fast, at this moment its cavity of resorption connection air; Simultaneously the pressurizing cylinder epicoele by Fill valve from the quick repairing of fuel tank to the oil cylinder epicoele, oil cylinder cavity of resorption fluid flows back to fuel tank.Up to F.F. piston rod contact workpiece, the balance that F.F. thrust and resistance reach, fast inlet casing stops and pressurize.
2, the supercharging worker advances the stage: when fast inlet casing F.F. thrust can't advance, pressurized cylinder began to the logical pressurized air of epicoele, and its piston drives the supercharging plunger that connects firmly together with it and puts in its cavity of resorption and air communication to pressurizing cylinder; Fill valve cuts off pressurizing cylinder epicoele and fuel tank simultaneously, and they no longer are communicated with.Pressurizing cylinder epicoele liquid is in closed state, and with putting in of supercharging plunger, its volume changes, the proportional rising of volume inner fluid pressure; Make the bigger power of pressurized cylinder output on the charged piston thereby act on, advance with F.F. cylinder piston supercharging worker, up to reaching job requirement.
3, quick reseting stage: the supercharging worker advances to finish, in the logical simultaneously pressurized air of cavity of resorption of fast inlet casing and pressurized cylinder, two cylinder epicoele blowing airs, pressurized cylinder fast return; Fill valve is communicated with pressurizing cylinder and fuel tank simultaneously, under the drive of F.F. cylinder piston, and the oil extraction of pressurizing cylinder epicoele, the cavity of resorption repairing puts in place up to fast inlet casing.So far, a course of work of pneumohydraulic pressure-cylinder finishes, and from the beginning next process repeats.
