How much do you know about the types of Rexroth hydraulic pumps? The hydraulic pump is the power element of the hydraulic system. It is driven by an engine or an electric motor. It sucks in oil from the hydraulic oil tank to form a pressure oil repellent and sends it to the actuating element. The types of Rexroth hydraulic pumps are: No. yi. Gear pumps: smaller in size, slightly larger in structure, less demanding for oil cleanliness, and cheaper; the pump shaft is subject to unbalanced forces, severe wear, and greater leakage. 2. Vane pump: It is divided into double dip-dye vane pump and single dip-dye vane pump. This kind of pump has uniform flow, stable operation, low noise, higher working pressure and volumetric efficiency than gear pumps, and its structure is more complicated than gear pumps. Third, the plunger pump: high volumetric efficiency, low leakage, can work under high pressure, mostly used in high-power hydraulic systems; but the structure is complex, the material and processing accuracy requirements are high, the price is expensive, and the cleanliness of the oil is high. The characteristics of Rexroth hydraulic pumps: First, how many seals are there and there is room for periodic changes. The output flow of the pump is proportional to the volume change of this space and the number of changes per unit time, and has nothing to do with other components. 2. The pressure of the liquid in the tank must be equal to or greater than the atmospheric pressure. This is the external condition that the positive displacement hydraulic pump can suck in oil. Therefore, in order to ensure that the hydraulic pump can absorb oil abnormally, the oil tank must be the same as the atmosphere, or a closed sub-filled oil tank must be used. Third, it has a corresponding flow distribution mechanism. Separate the suction tank and the discharge tank to ensure that the hydraulic pump continuously sucks and discharges liquid regularly.
