Electric hydraulic pump structure

Electric fluid pump in China, the use of more and more widely in many areas it has no other advantages of the pump equipment, electric hydraulic pump types mainly gear pump, vane pump and plunger pump three Product composition. Schematic diagram of electric hydraulic pump (Asia Fluid Network) 1, electric hydraulic pump purposes: electric hydraulic pump is to provide a hydraulic fluid pressure of a hydraulic component, is a pump. Its function is to convert the mechanical energy of power machines (such as electric motors and internal combustion engines) into liquid pressure energy. Electric hydraulic pump output flow can be adjusted according to need called variable pump, the output flow can not be adjusted electric pump called quantitative pump. 2, electric hydraulic pump types: hydraulic system commonly used electric hydraulic pump gear pump, vane pump and plunger pump 3 kinds. 1) gear pump: smaller, simple structure, less stringent requirements on the cleanliness of oil, the cheaper prices; but the pump shaft by the unbalanced force, serious wear and tear, leakage larger. 2) vane pump: divided into double-acting vane pump and single-action vane pump. This pump flow uniform, smooth operation, low noise, work pressure and volumetric 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 for high-power hydraulic system; but the structure is complex, high material and processing accuracy, expensive, demanding clean oil. Generally in the gear pump and vane pump can not meet the requirements of the plunger pump. Domestic piston pump can also meet the needs of domestic customers can reach 80MPA pressure, but the price is cheaper than imported, quality and performance are no problem. 4) There are some other forms of hydraulic pumps, such as screw pumps, but not as good as the above three kinds of universal. Many times the use of electric hydraulic pump products should pay special attention to its structure, different types of electric pump products may also be slightly different structure, these differences are the actual use of different roles in the embodiment. With the increasing demand for electric hydraulic pumps, accelerating the research and development of such products has become very necessary.
