The hydraulic control system of vulcanized press and fittings
At this time into the oil cylinder of the hydraulic oil, because of the single valve can't back, forcing cylinder rod up, and then work continue to make the hydraulic oil into the hydraulic cylinder, thus rising
Answer: hydraulic principle is power element. The pressure on the closed liquid is passed in all directions. Additional: five parts of hydraulic cylinder: cylinder, cylinder cover, piston and piston rod, sealing device, buffer and exhaust device. The working principle of each cylinder is similar, through the manual booster lever (hydraulic manual pump) to allow hydraulic oil to pass a single valve into the cylinder
Turn on the hydraulic valve when it is coming down, and the hydraulic tank. This is the simplest working principle, and everything else is improved on this basis.
