Step 1 hydraulic cylinder design, master raw materials and the design basis, including: the host uses and working conditions; structural features of work organization, load conditions, stroke size and movement requirements; selected hydraulic system operating pressure and flow; the reality of materials, parts and processing; the relevant national standards and technical specifications. 2. The hydraulic cylinders are exposed to the external load force large hydraulic engineering cylinders and reasonable price, such as gravity, external kinematic friction, inertia force and the work load, to determine the variation of the hydraulic cylinder at each stage of the trip, and the load that must be provided power values. 3, according to the hydraulic cylinder workloads and selected oil pressure of work, to determine the diameter of the piston and the piston rod 4, according to the work schedule requirements, determine the maximum working length L of the hydraulic cylinder hydraulic engineering cylinders, usually L> = D, D for rod diameter. Due to the elongated rod, should be stability and longitudinal bending strength check calculation of hydraulic cylinders. Piston hydraulic cylinder piston works only one-way movement of large hydraulic engineering cylinders wholesale authentic, 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, by hydraulic pressure of the cylinder to achieve a single direction of movement, the movement in the opposite direction by an external force (e.g. spring force, its own weight or external loads, etc.) to achieve; and bis acting hydraulic cylinder piston movement in both directions through the two chambers alternately into the oil, by the action of hydraulic 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. In the same amount of oil, into the oil chamber of different double-acting hydraulic cylinders engineering factory, piston velocity is different; the need to overcome the load force is the same, different chamber into the oil, the oil pressure required is different, or that the system After the pressure settings, sanitation garbage truck hydraulic cylinder movement in both directions to overcome load force large hydraulic engineering different wholesale authentic quality speed hydraulic cylinders _ _ Bengbu hydraulic engineering cylinders provided by Dezhou City mass-velocity hydraulic machinery factory.
