The working principle of positive displacement hydraulic pump Hydraulic pump is based on changes in the volume of the seal to achieve oil and oil pressure, the size of the oil discharge depends on the volume of the sealed chamber changes, so this type of hydraulic pump, also known as displacement hydraulic pump. Constitute a positive displacement hydraulic pump two necessary conditions are: â‘ a cyclical change in the sealing volume, sealing volume from small to large oil, from large to small pressure; â‘¡ with a flow device, which ensures that the sealed volume from small to large When only connected with the suction pipe, the sealing volume from large to small when only connected with the pressure pipe. The working principle of displacement hydraulic motor and the positive displacement hydraulic pump is reverse. If you can turn the piston working chamber turns pressure oil and fuel tank, it will make the crankshaft rotation. During one half of the cycle, the pressure of the fluid can be converted to mechanical energy; the spent fluid medium is discharged during the other half of the cycle. According to different structure, hydraulic pump is divided into gear pump, vane pump, piston pump and screw pump and other types. Press the output flow can be adjusted, can be divided into quantitative pumps and variable pumps.
