The difference between variable vane pump and fixed vane pump

August 05, 2022
Variable vane pump and vane pump have the advantages of low noise, high efficiency, relatively low cost, etc., then how to distinguish between the two? Variable vane pump and the difference between the quantitative vane pump First of all, You can distinguish between the two based on speed. Under the conditions of constant speed, the pressure is constant The output flow can be adjusted for the variable vane pump, the pressure is constant and the flow is not adjustable for the quantitative vane pump. Their biggest difference is that the variable displacement vane pump shaft is easy to install. Second, you can distinguish between the two based on traffic and stress. Simply quantitative vane pump speed selected, his flow and pressure is determined, it can not be adjusted. Variable vane pump output flow can be based on the pressure changes in the hydraulic system (external load size), automatically adjusts the flow, that is, the pressure is high, the output flow is small, the pressure is low, the output flow, so he can save the number of hydraulic components, which Simplifies the oil system and reduces oil heating. The disadvantage is that the flow pulsation serious hydraulic system pressure is not stable, short pump life, pump bearings easily broken, because he is the heart of the installation, and the pump noise.
