CASAPPA马达POLARIS系列介绍
现代机械的电路越来越复杂，通常需要单独和独立运动的组合。 POLARIS 10 和 POLARIS 20 分流器提供高技术、低成本的动力传输，并解决液压流量分配的应用问题。 根据简化液压回路设计的策略，分流器内置有溢流阀，用于限制压力并防止气蚀。
这些组件可以巧妙地优化液压回路并降低安装成本。 POLARIS 分流器是两个或多个具有公共内部连接轴的部分分配器。 这根据截面位移保持通过每个截面的流量之间的恒定比率。 旋转分流器的理论工作实际上不会耗散能量，如果一个部分的出口压力低于输入压力，该部分将作为电动机运行并从流体中获取能量。 该能量不会被浪费，而是通过公共轴转移到作为泵运行的其他部分，因此需要出口压力大于入口压力。 在工况下，整体效率取决于单段效率之和。
因此，这些产品可用作流量均衡器、分流器和增压器。
Modern machinery with increasingly complex circuits often needs combinations of separate and independent movements. POLARIS 10 and POLARIS 20 flow dividers provide technically advanced, low cost power transmission and solve application problems wherever hydraulic flow has divided. In line with our policy of simplifying the design of hydraulic circuits, our flow dividers have relief valves built into limit pressure and prevent cavitation.
These components permit hydraulic circuits to be cleverly optimised and reduce installation costs. The POLARIS flow dividers are two or more section dividers with a common internal connecting shaft. This maintains a constant ratio between the flows through each section in accordance with section displacement. Theoretical working of rotary flow dividers do not dissipate energy in fact if the outlet pressure of one section drops below input pressure, that section operates as a motor and takes energy from the fluid. This energy is not wasted but transferred by the common shaft to the other sections which operate as pumps and therefore need outlet pressure to be greater than inlet pressure. In working conditions, overall efficiencies depend on the sum of the single sections efficiency.
These products can therefore be used as flow equalizers, flow dividers and pressure intensifiers.
