Hydraulic Pumps can be mainly divided into hydrostatic and hydrodynamic. The former is a kind positive displacement pumps. Being distinguished from hydrostatic pump, the later one can be fixed displacement, in which the displacement cannot be adjusted. At the same time, hydrodynamic pumps have a more complicated construction that allows the displacement to be adjusted in special need by the user.
How does the hydraulic pump work?
It works based on Pascal’s Law which states “The pressure, in a static hydraulic fluid in a closed system is everywhere the same”. Generally, in a hydraulic pump, water or another fluid is highly pressurized and moved through various motors and cylinders. To control the fluid various valves, hoses and tubes block or disperse the fluid creating the pressure and force without the need of an external power source. By using the kinetic energy (molecular energy) of the water/fluid to power the pump, no electricity is needed. And according to the law, if you increase the pressure in one area of a system, it increases throughout the system.
Of course, like many other types of pumps, the hydraulic pump also has a wide range of applications. Its application can be summarized as transferring and circulation of liquids within light industry and farming irrigation and pressure boosting. And it also can be applied tin cooling systems and air-conditioning systems.
