DANA Flow Divider

DANA Flow Divider

A flow divider Includes two or more modular elements (sections) with gears mechanically linked an Internal shaft that causes them to turn at the same speed.
Unlike multiple pumps, In which the Input power is mechanical (pump shaft connected to a motor), In a flow divider the Input power is of a fluid-mechanical nature.
In a circuit with a flow divider there is a flow of oil inder pressure that suppplies the modular elements parallel and the modular elements are in turn connected to the hydraulic circuit serving the actuators.
The portion of the flow utilized by each element is solely determinated by its nominal flow rate.
Therefore, unlike stadard static dividers with variable ports, the flow dividers do not cause dissipation and are much more precise.
Theoretical working of rotary flow dividers do not dissipate enetgy 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 efficiences depend on the sum to the single sections effuciency.
The use of flow dividers in a system reduces the number of pumps secessary as well as the associated individual mechanical power takeoff and complex mechanichal couplers.
The gear flow dividers, if correctly used, permit to optimize hydraulic circuits and to reduce the installation costs.
