Principle Of Hydraulic Transmission Pressure Of Hydraulic Cylinder

The principle of hydraulic cylinder pressure transmission remains consistent: the pressure is determined by the area of the piston. A larger piston area results in higher pressure, while a smaller area leads to lower pressure. Electric hydraulic jacks are components of hydraulic transmission systems. They convert hydraulic energy into mechanical energy. Electric jacks can be used individually or in combination with other jacks or mechanisms to perform specific tasks. Hydraulic cylinders are widely used in machine tool hydraulic systems due to their simple structure and reliable operation.
An electric jack is a type of hydraulic actuator that converts hydraulic energy into mechanical energy, enabling linear reciprocating or rocking motion. It operates reliably with a simple structure. Leverage principles also apply to jacks. Jacks, whether mechanical or hydraulic, are relatively simple lifting devices with small lifting heights (usually less than 1m). Mechanical jacks come in rack and screw types but require manual effort due to their limited lifting capacity. Hydraulic jacks, on the other hand, have a compact structure, stable operation, and self-locking effect, which makes them widely used. However, they have limitations in terms of lifting height and speed. Hydraulic jacks are classified as general or special-purpose jacks.
Special hydraulic cylinders can be used as tensioning tools for prestressed concrete component manufacturing, specifically for applying tension to prestressed steel bars. Most special hydraulic jacks are double-acting types, such as through-hole jacks and cone-anchor jacks. Through-hole jacks are suitable for tensioning steel tendons or wire bundles. They consist of a tensioning cylinder, pressing cylinder, pressing piston, and spring.
