Piston oil cylinder: The transmission of force and motion is achieved through the reciprocating motion of the piston in the cylinder barrel. It has a simple structure and reliable operation, and is one of the most common types of large oil cylinders.
Piston oil cylinder: composed of a plunger and a cylinder barrel, the plunger is only subjected to unidirectional force, and the return requires external force or self weight, suitable for large equipment with a long stroke.
Swing type oil cylinder: capable of achieving rotational motion at a certain angle and outputting torque, commonly used in large machinery that requires rotary action, such as ship servo swing oil cylinder and mining machinery rotary mechanism oil cylinder
Classified by work pressure level
High pressure oil cylinder: The working pressure is usually above 14MPa and can withstand huge loads. It is widely used in metallurgy, heavy machinery and other fields, such as high-pressure oil cylinders for large presses and hydraulic presses
Ultra high pressure oil cylinder: With a pressure of up to 21MPa and above, it is specifically designed for extreme working conditions, such as ultra-high pressure oil cylinders for large engineering equipment and ultra-high pressure oil cylinders for offshore platform lifting devices
Classified by purpose and function
Lifting cylinder: mainly used for lifting heavy objects, such as lifting equipment in car maintenance and synchronous lifting systems for large bridges.
Push pull oil cylinder: realizes linear push pull action, commonly used in the telescopic arm drive of large machine tools and port cranes.
Damping cylinder: By controlling the flow velocity of hydraulic oil, it buffers impact and vibration, protecting the stability of large equipment during operation, such as the buffering mechanism 1 of large forging equipment.
Classified by degree of customization
Standard large oil cylinder: Designed and manufactured according to general standards, it has a wide range of applicability, such as HSG type engineering
Hydraulic Cylinder and DG type vehicle hydraulic cylinder.
Customized large oil cylinders: Personalized design based on specific engineering requirements, such as cylinder bodies with ultra large diameters (greater than 500mm), oil cylinders with special stroke or installation methods, commonly used in large special machinery equipment.
From the above classification, it can be seen that the classification of multi-stage telescopic oil cylinders needs to be based on structural characteristics, power modes, and application requirements. Different categories of products have significant differences in stroke, load capacity, and control accuracy, which can meet diverse needs from ordinary machinery to special engineering.
