Design of hydraulic cylinder of plane gate hoist
Abstract
Hydraulic hoist is mainly used in hydraulic engineering gate, hydraulic hoist has a significant advantage:Technology leader, layout rigorous, craft, price is cheap; the operation is stable, safe, reliable, high efficiency;Can realize stepless speed regulation; easy to centralized control, automatic operation is simple, convenient maintenance;Hydraulic hoist is conducive to optimizing the overall water industry and trade of the building is placed, it in water conservancy, navigation locks, power generation, flood control flood control projects use by leaps and bounds.But in the practical application, the hydraulic hoist still has many problems which are puzzling its development, which needs to be solved urgently.Especially for the water conservancy and hydropower project, the design and application of hydraulic cylinder of large hydraulic cylinder is put forward.
Hydraulic cylinder is the main structure of the hydraulic hoist. The performance of the hydraulic cylinder is directly related to the good operation of the gate.After consulting a large amount of relevant data, the paper analyzes the development trend of the hydraulic cylinder, and designs the hydraulic cylinder.The design includes the selection of working load of the hydraulic cylinder, cylinder, cylinder, piston rod, piston, septum, guide sleeve and exhaust device design,The design of the connection between the sealing element, cylinder and end cap, the thickness of the cylinder wall, the strength and stability of the piston rod, the strength of the connection bolt and the installation method of the hydraulic cylinder.
