The general design of the hydraulic cylinder step 1) master the original data and the design basis, including: host uses and working conditions; structural features work organization, load conditions, stroke size and movement requirements; hydraulic system operating pressure and flow rate selected ; the reality of materials, parts and processing technology; relevant national standards and technical specifications. 2) Select the type of structure and operation of the hydraulic cylinder according to the requirements of the host. 3) The hydraulic cylinder is exposed to the external load forces, such as gravity, friction and external body motion, the inertial force and the work load on the hydraulic cylinder to determine the variation of the stroke of the load on each phase and a power value must be supplied. 4) According to the hydraulic cylinder workload and selected fluid pressure of work, determine the diameter of the piston and piston rod. 5) The moving speed of the hydraulic cylinder, the piston and rod diameter determine the flow rate of the hydraulic pump. 6) Select the cylinder material, calculated outside diameter. 7) Select the cylinder head structure, the calculation of the cylinder head and cylinder connection strength. 8) According to the working stroke requirements, determine the maximum working length of the cylinder L, typically L> = D, D is the diameter of the piston rod. Due to the elongated rod should be stability and longitudinal bending strength check calculation of the hydraulic cylinder. 9) When necessary to design a buffer, exhaust and dust and other devices. 10) Draw the hydraulic cylinder assembly drawings and part drawings. 11) finishing design calculations, drawings and other technical documents validation. Hydraulic cylinder design issues to consider 1) to ensure the speed of the hydraulic cylinder reciprocating stroke needed traction. 2) To minimize the dimensions of the cylinder, so compact. 3) by the pull rod is best under pressure, to avoid bending. 4) to ensure that each part has sufficient strength, rigidity and durability. 5) Try to avoid hydraulic cylinder under lateral load. 6) When a long stroke hydraulic cylinder piston rod should avoid sagging. 7) to eliminate the deflection of the piston, the piston rod and the guide rail. 8) According to the hydraulic cylinder working conditions and circumstances, to consider buffering, exhaust and dust control measures. 9) have likely sealed to prevent leakage. 10) when the cylinder is not due to temperature changes, and is deflected restricted. Especially the long cylinders should pay attention. 11) structural elements of the hydraulic cylinder standard series sizes should be used, try to choose a standard often used. 12) try to make low-cost, easy to manufacture, easy maintenance.
