Electric pump advantages and disadvantages Do you understand?

[Asia pump network hearing] Electric hydraulic pump is to provide 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. Output flow can be adjusted according to the needs of the variable pump, called the quantitative pump can not be adjusted. Hydraulic system commonly used pump gear pump, vane pump and plunger pump three. Electric pump advantages and disadvantages Do you understand? 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. Vane pump: divided into double-acting vane pump and electric single-action electric pump hydraulic 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. Piston pump: high volumetric efficiency, small leakage, can work under high pressure, mostly for high-power hydraulic system; but the structure is complex, high requirements of materials and processing precision, expensive, high cleanliness of oil. Generally in the gear pump and vane pump can not meet the requirements of the plunger pump. There are some other forms of hydraulic pumps, such as screw pumps, but not as good as the above three applications. In the past, the products of our country all depend on imports, but with the increasing demand for such products in our country, our domestic products can also meet the production needs. We have a great advantage in terms of price, meanwhile, Performance, we also have the same advantage. So the advantages and disadvantages of electric hydraulic pump in concrete performance? Output flow can be adjusted according to the needs of the variable pump called, the flow can not be adjusted as a quantitative pump. Hydraulic system commonly used pump gear pump, vane pump and plunger pump 3 kinds. 1, gear pump: Advantages: smaller size, simple structure, less stringent requirements on oil cleanliness, cheaper prices. Disadvantages: pump shaft unbalanced force, serious wear and tear, leakage larger. 2, vane pump: advantages: divided into double-acting vane pump and single-action vane pump, this pump flow uniform, smooth operation, low noise, working pressure and volumetric efficiency than the gear pump. Disadvantages: structure than the gear pump complex. 3, piston pump: Advantages: high volumetric efficiency, small leakage, can work under high pressure, mostly for high-power hydraulic system. Disadvantages: complex structure, demanding materials and processing accuracy, the price is expensive, the oil cleanliness requirements. Generally in the gear pump and vane pump can not meet the requirements of the plunger pump. There are some other forms of hydraulic pumps, such as screw pumps, but not as good as the above three kinds of universal. Through the analysis of the above three kinds of pumps, we can further understand that the advantages and disadvantages of the electro-hydraulic pump in different models and types may not be the same, but because of these differences, users can make the product purchase more Many options, such a variety of significance for the production. As many industries in our country increasingly demand such products, they are urgently needed to improve and innovate.
