Lift platform of hydraulic oil cylinder use requirement
1, ensure the reciprocating movement of the hydraulic cylinder to get the required speed, stroke and force;
Cargo-lifts use hydraulic oil cylinder to choose the structure of cylinder head, calculation of the connection strength of cylinder head and cylinder;
2, according to the requirements of the cargo-lifts action to choose the type and structure of the hydraulic cylinder form;
(1) the structural elements of the hydraulic cylinder, to adopt standard series size, as far as possible choose often use standard parts and seals;
(2) manufacturing easy, maintenance simple, low cost.
3, design the buffer when necessary, exhaust and dust control device;
4, according to the hydraulic cylinder of the workload and the selected oil pressure of work, determine the diameter of the piston and piston rod;
(1) the size of the reasonable design and selection of pole.
(2) ensure that the hydraulic cylinder each parts have enough strength, stiffness and life;
(3) in the selection of hydraulic pump oil pressure and flow conditions, in order to try to reduce the size of the hydraulic cylinder;
(4) the best make the piston rod tension at work, lest produce buckling,
(5) the hydraulic cylinder should be avoid as far as possible under lateral load;
5, according to the rate of movement of the hydraulic cylinder, piston and piston rod diameter, determine the flow of hydraulic pump. ;
(1) due to changes in temperature elongation, hydraulic cylinder cannot be the deflection due to constrained;
(2) according to the requirement of the machinery and equipment, choose the appropriate buffer, dust and exhaust;
(3) the structure design of the hydraulic cylinder should fully pay attention to the technology of parts processing and assembly,
6, choose the cylinder material, calculated outside diameters;
7, drawing hydraulic cylinder assembly drawing and part drawing;
8, according to heilongjiang cargo-lifts work schedule requirements, determine the maximum working length L of the hydraulic cylinder, usually L > = D, D for piston rod diameter. Because of the slender rod, should carry on the longitudinal bending strength checking and stability calculation of the hydraulic cylinder;
(1) hydraulic cylinder axis should be consistent and to be the movement direction of the drag mechanism,
(1) avoid sagging during long hydraulic cylinder piston rod out;
(3) the various parts of the hydraulic cylinder sealing is reliable, less leakage. The friction is small;
