Hydraulic pump to provide pressurized fluid to a hydraulic device for hydraulic transmission, is a pump. Its function is to power machine (such as a motor and an internal combustion engine, etc.) of the mechanical energy into pressure energy of the liquid. Output flow can be adjusted as needed is called variable displacement pump, the flow rate can not be adjusted is called a metering pump. Hydraulic systems commonly used in pump gear pumps, vane pumps and piston pumps three kinds. Today, the development of the machinery industry is getting ahead of refinement variable pump, while the hydraulic industry also will be vacated born. Hydraulic power units is variable displacement pump hydraulic system monopoly, its role is the original motivation of the mechanical energy into fluid pressure energy, refers to the hydraulic system of pumps, which provides power to the entire hydraulic system. The general structure hydraulic gear pumps, vane pumps and piston pumps. By Cipian introduction, makes you a better understanding of the hydraulic pump.
