Hydraulic power machinery is a kind of mechanical equipment that uses liquid to transfer energy to realize force and motion. Its working principle can be simply summarized as the use of liquid to transfer pressure and force characteristics. In hydraulic systems, liquid is used as the medium for transferring energy. When a pressure is applied to a liquid, the liquid transmits the pressure and maintains the same magnitude and direction. This property is called Pascal's law ".
The hydraulic system is usually composed of hydraulic pump, hydraulic cylinder, hydraulic valve and pipeline. When working, the hydraulic pump will produce high-pressure liquid and deliver it to the hydraulic cylinder through the pipeline. When the valve is opened, the fluid flows into the hydraulic cylinder, moving the piston, thereby generating force and pushing the load to complete the work.
The working principle of hydraulic power machinery has the advantages of greater transmission force, stable action, controllable operation, long life and so on. Therefore, it is widely used in many fields such as factory production lines, construction engineering and agricultural machinery.
In general, the working principle of hydraulic power machinery is based on the characteristics of liquid transmission pressure and force, and the force and movement are realized through the hydraulic system, which provides efficient and reliable power support for industrial production.
