Hydraulic cylinder design steps

On the hydraulic cylinder design steps are as follows:

(1) grasp the original information and design basis, mainly including: the use of the host and working conditions; working mechanism of the structural characteristics, load conditions, stroke size and action requirements; hydraulic system selected working pressure and flow; materials, Accessories and processing technology of the real situation; relevant national standards and technical specifications.

(2) Select the type and structure of the hydraulic cylinder according to the action requirements of the host.

(3) According to the hydraulic cylinder to withstand the external load force, such as gravity, friction, inertia and work load, determine the hydraulic cylinder type and structure form. Force and working load, to determine the rule of change of the hydraulic cylinder in the various stages of the stroke on the load and the value of the power must be provided.

(4) According to the working load of the hydraulic cylinder and the selected working pressure of the fluid, determine the diameter of the piston and piston rod.

(5) According to the movement speed of the hydraulic cylinder, piston and piston rod diameter, determine the flow rate of the hydraulic pump.

(6) Select the cylinder material, calculate the outer diameter of the cylinder.

(7) Select the structural form of the cylinder head, calculate the strength of the cylinder head and cylinder connection.

(8) According to the requirements of the working stroke, determine the maximum working length of the hydraulic cylinder L, usually L> = D, D for the piston rod diameter. Diameter. As the piston rod is long and thin, longitudinal bending strength should be checked and the stability of the hydraulic cylinder calculation.

(9) If necessary, the design of buffer, exhaust and dust protection devices.

(10) Drawing hydraulic cylinder assembly and parts drawings.

(11) collate the design calculations, audited drawings and other technical documents.
