The working principle of sc cylinder related knowledge

Working principle of the sc cylinder knowledge generally refers to sc cylinder cylinder combined with hydraulic cylinder form gas-liquid damping cylinder, gas-liquid boosting cylinder, etc. As is known to all, usually cylinder is compressed air as the working medium, its characteristic is fast, but not easy to control speed, when the load change is bigger, prone to 'crawl' or 'walk from the phenomenon; The hydraulic cylinder use working medium is usually considered incompressible hydraulic oil, its characteristic is as cylinder move quickly, but the conditions of the Canadian immigration rate is easy to control, when the load change is bigger, adopt appropriate measures, general won't produce 'crawl' and 'walk from the phenomenon. The cylinder and the hydraulic cylinder ingenious combination, complement each other, which became widely used in pneumatic system of gas-liquid damping cylinder. Is actually a sc cylinder and hydraulic cylinder series, two piston fixed on the same piston rod. Hydraulic cylinder without pump oil, as long as full of oil, is equipped with hydraulic check valve, throttle valve, and between its import and export of oil cup. When the right end gas cylinder, cylinder to overcome the load safety cabinet hydraulic cylinder piston movement to the left ( The left cylinder exhaust) , the left side of discharge of the hydraulic cylinder, one-way valve closed, only through the throttle valve into the hydraulic oil cylinder cavity and oil cup, right at this moment if the throttle valve opening, cavity discharge of oil hydraulic cylinder left unobstructed, two piston movement speed is fast, on the contrary, if the throttle valve down, discharge of oil hydraulic cylinder left cavity is blocked, two piston movement speed will slow. Adjust the throttle valve opening size, can control the rate of movement of the piston. It can be seen that the output force of gas-liquid damping cylinder should be the force created by the compressed air in the cylinder, Push or pull) The difference of the CPC with hydraulic cylinder damping force.
