What is the type of hydraulic pump

Hydraulic pump is a hydraulic system of power components, the work is mainly driven by the engine or motor, sucked in from the hydraulic tank, forming a pressure oil discharge, sent to the implementation of an element. Hydraulic pump according to the structure of its type can be divided into gear pump, piston pump, vane pump and screw pump. As people's demand for hydraulic systems continues to grow, so does the demand for hydraulic pumps. Because of its different flow and structure, the type of hydraulic pump is not the same. So what kind of hydraulic pump in the end? Types of hydraulic pumps What are the commonly used types of hydraulic pumps: 1, according to whether the flow can be adjusted can be divided into: variable and quantitative pumps. Output flow can be adjusted according to the needs of the variable pump, called the quantitative pump can not be adjusted. 2, according to the hydraulic system commonly used pump structure is divided into: gear pump, vane pump and plunger pump 3 kinds. 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 single-action vane pump. This pump flow uniform, smooth operation, low noise, 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 kinds of universal. Through the above analysis, we can very clearly understand that the hydraulic pump according to the flow to divide its variable and quantitative pumps, divided according to the structure can be divided into gear pumps, vane pumps divided piston pump. As the use of such products continues to increase, research on such products has also been accelerated.
