How to choice the correct Hydraulic Pump(Piston Pump,Vane Pump,Gear Pump)

 Hydraulic pump is the power component of the hydraulic system, is by the engine or motor drive, from the hydraulic oil tank in the inhalation of oil, the formation of pressure oil discharge, to the implementation of components of a component. Hydraulic pump according to the structure is divided into gear pump, piston pump, vane pump and screw pump.
 Hydraulic Pump can be divided according to the flow : variable displacement pump and fixed displacement pump.
 According to the hydraulic system used in the pump structure is divided into: gear pump, vane pump and piston pump.
 1,Gear pump: small size, simple structure, the cleanliness of the oil is not strict, the price is relatively cheap, but the pump shaft by the imbalance force, serious wear and tear
 2,Vane pump: divided into two acting vane pump and single acting vane pump. The pump flow uniformity, smooth operation, low noise, pressure and volume efficiency than the gear pump, the structure is more complex than the gear pump 
3,Piston pump: high volumetric efficiency, small leakage, can work under high pressure, mostly used for high power hydraulic system, but the structure is complex, the material and processing accuracy is high, the price is expensive, the oil cleanliness requirements are high.
