Hydraulic Flow Divider
1. Technical Definition
A hydraulic flow divider is a hydraulic control device designed to split hydraulic fluid flow from a single source into two or more separate circuits while maintaining proportional flow distribution. It ensures that multiple hydraulic components receive the correct amount of hydraulic oil simultaneously.
Flow dividers are commonly used when two actuators or hydraulic systems must operate together and receive balanced hydraulic flow.
In roll forming machines, hydraulic flow dividers are commonly used in systems supporting:
Hydraulic punching systems with multiple cylinders
Hydraulic lifting mechanisms
Hydraulic actuator synchronization systems
Hydraulic press assemblies
Hydraulic power distribution circuits
They ensure consistent hydraulic performance across multiple circuits.
2. Where It Is Located
Hydraulic flow dividers are installed in hydraulic supply lines where fluid flow must be distributed to multiple hydraulic circuits.
Common installation locations in roll forming machines include:
Hydraulic manifold blocks
Hydraulic supply lines after the pump
Hydraulic actuator supply circuits
Hydraulic cylinder synchronization systems
Hydraulic press mechanisms
They are typically installed close to the components that require balanced flow.
3. Primary Functions
3.1 Divide Hydraulic Flow
Splits hydraulic oil into two or more circuits.
3.2 Synchronize Hydraulic Actuators
Ensures multiple cylinders move at the same speed.
3.3 Maintain Balanced System Operation
Prevents uneven hydraulic movement.
3.4 Improve Hydraulic Control
Allows precise distribution of hydraulic fluid.
4. How It Works
Hydraulic flow dividers regulate fluid distribution using internal mechanical or gear mechanisms.
Typical operation process:
Hydraulic oil enters the flow divider through a single inlet port.
Internal mechanisms divide the incoming flow.
The divided flow exits through multiple outlet ports.
Each outlet receives a proportional share of the fluid.
Hydraulic actuators connected to each outlet operate simultaneously.
This ensures balanced and synchronized hydraulic movement.
5. Types of Hydraulic Flow Dividers
