Hydraulic, pneumatic and sealing industry development process of hydraulic, pneumatic and sealing industry development process can be divided into three stages, namely: the early 1950s to early 1960s infancy; 60 to 70 years for specialized production system growth stage; 80 to 90 years of rapid development stage. Where 1500T cylinders, hydraulic industry in imitation of the Soviet Union in the early 1950s grinder, broaching, copying lathes and other hydraulic transmission started, hydraulic components plant by the machine hydraulic workshop production, production for own production from the machine tool industry. By the late 1960s, early 1970s, with the development of mechanization of production, especially in the second car factory to provide efficient, driven automation equipment, hydraulic components manufacturing industry experienced rapid development of the situation, a group of SMEs has become a professional manufacturer of hydraulic parts. Hydraulic cylinder piston works only one-way movement of the piston cylinder manufacturer, its movement in the opposite direction from the force required to complete. But its stroke hydraulic cylinder piston generally more big. Hydraulic cylinder piston rod can be divided into single and double rod two structures fixed by way of fixed and fixed two cylinder piston rod, according to the role of fluid pressure in the case of a single-acting and double-acting. In a single-acting hydraulic cylinder, the pressure oil chamber is for a hydraulic cylinder, hydraulic pressure against the direction of movement of the cylinder to achieve a single cylinder, the opposite direction by an external force (e.g. spring force, its own weight or external loads, etc.) to achieve; and double-acting hydraulic cylinder piston movement in both directions through the two chambers alternately into the oil, by the effect of fluid pressure to complete. Single-pole double-acting hydraulic cylinder piston. There is only one side of the piston rod, and thus the effective role of different areas of the two chambers. Are the same, different chamber into the oil, the piston velocity at different fuel supply; load force to be overcome in the same, different 50T cylinder into the oil chamber, the required supply pressure of different, or the pressure settings in the system after , sanitation garbage truck hydraulic cylinder movement in both directions to overcome load force different cylinder manufacturers, Mianyang cylinders, hydraulic speed quality provided by the mass-velocity Dezhou City, hydraulic machinery factory. Dezhou City mass-velocity hydraulic machinery plant (www.dzzhisu.com) (www.dzzhisu.com) strong, credible, in Dezhou hydraulic equipment industry has accumulated a large number of loyal customers. The company better work attitude and constantly improve the quality of innovative ideas will lead you hand speed hydraulic and into the brilliant, for a better future!
