Cast Iron Hydraulic Gear Flow Divider

Cast iron hydraulic synchronous flow dividers are core precision components in hydraulic systems that achieve synchronized speed control of multiple actuators. The valve body is primarily made of cast iron, making it suitable for high-pressure, heavy-duty applications. Structurally, they are mainly divided into two categories: gear type and flow dividing/combining valves. The synchronization accuracy typically reaches ±1% to ±3%, and they are widely used in engineering machinery, metallurgy, mining, and other fields.

Product Introduction

Feature of cast iron hydraulic gear flow divider


1. High strength and durability
Cast iron materials have high mechanical strength and wear resistance, and can withstand large pressure and impact loads.
Suitable for high pressure and heavy load conditions.

 

2.Good corrosion resistance
Cast iron material has certain corrosion resistance and can resist the erosion of various chemical media.
Suitable for corrosive environments such as chemical industry and petroleum.

 

3. Excellent sealing performance
Cast iron diverters are usually equipped with high-quality seals to ensure that the fluid does not leak during the diverting process.
Suitable for occasions requiring high sealing performance

Working principle of cast iron hydraulic gear flow divider
The working principle of a gear flow divider is based on the intermeshing of gears.

When one gear rotates, other gears will also rotate through the meshing effect of the gears, thereby achieving power distribution and synchronous output.

Differences in performance between cast iron and aluminum gear flow divider

Cast iron gear flow divider:
1‌. High strength‌: Cast iron material has high compressive and tensile strength and is suitable for bearing larger loads.
2‌. Good wear resistance‌: Cast iron material has good wear resistance and is suitable for frequent use occasions.
‌3. Poor thermal conductivity‌: Cast iron has poor thermal conductivity and is not suitable for applications that require rapid heat dissipation‌

 

‌Aluminum gear flow divider
‌1. Light weight‌: The density of aluminum alloy material is low, which reduces the overall weight and makes it easy to carry.
‌2. Good thermal conductivity‌: Aluminum alloy has good thermal conductivity and helps to dissipate heat quickly

Application of cast iron hydraulic gear flow divider

Gear flow dividers are mainly used in situations where synchronous output of multiple output shafts is required.

For example, in tunnel boring machines, gear flow dividers are used to divert or combine hydraulic components to ensure stable operation of the machine.

In addition, the gear flow dividers can also divide equal amounts of oil from the oil pump into two, four or multiple ways, up to 12 ways, or perform accurate splitting in different proportions, and is widely used in various hydraulic systems.
