I believe that most users understand that for Vickers vane pump, as long as the swash plate inclination angle or cylinder swing angle can change its displacement and output flow, so as to realize the speed regulation of hydraulic motor or hydraulic cylinder, which is an important feature of Vickers vane pump. So do you know the regulation knowledge of Vickers vane pump? Let's give you a detailed explanation of the regulation knowledge of Vickers vane pumps as follows:
Explanation of the regulation knowledge of Vickers vane pumps
First, the adjustment can be continuous, stepless, or it can be carried out without stopping during the working process of the hydraulic system.
Second, by changing the displacement to achieve speed regulation becomes volumetric speed regulation, this method and another so-called throttling speed regulation, the power loss is small, avoiding the system heating, very suitable for high-power systems.
Third, although the rigid pressure-flow characteristics of positive displacement pumps are very valuable for hydraulic transmission, they often contradict the requirements of flow regulation, so it is necessary to modify the original pressure-flow characteristics of positive displacement pumps. This is the task of the variable regulating mechanism.
Fourth, the power source and control methods that promote the action of the variable mechanism in the Vickers vane pump are diverse, but generally can be layered into two categories:
1. One is the direct regulation or control of the variable mechanism by external force or external signal;
2. The other type is to use the flow, pressure, power and other working parameters of the pump itself as signals, and realize the feedback control of its flow, pressure and power by changing and controlling the displacement of the pump, and automatically adjust.
