product structure
The structure of hydraulic filter cartridge oil filters can vary according to their type and design, but generally, they comprise the following key components:
I. Outer Shell
Material: The outer shell is typically made of metal materials such as stainless steel to ensure strength and corrosion resistance.
Function: The shell not only protects the internal filter element but also serves as the support structure for the entire filter.
II. Filter Element
Material: The filter element is the core of the hydraulic filter cartridge oil filter, and its materials are diverse, including stainless steel woven mesh, sintered mesh, iron woven mesh, etc. The filter media primarily consist of glass fiber filter paper, synthetic fiber filter paper, and wood pulp filter paper.
Structure: The filter element is typically composed of single or multiple layers of metal mesh and filter media. The number of layers and the mesh size are determined based on the specific operating conditions and applications. For instance, some filters employ a mesh-type structure where a porous U-shaped frame is covered with one or two layers of copper mesh, while others use a sintered filter element made by melting and bonding particulate metal powder at high temperatures.
Working Principle: As oil passes through the filter element, solid particles are trapped outside, allowing clean oil to flow through and exit, thus achieving filtration.
III. Seals
Function: Seals ensure the tightness between the filter element and the outer shell, preventing unfiltered oil from bypassing the filter.
Material: Seals are often made of elastomeric materials such as rubber or silicone.
IV. Other Components
Oil Inlet and Outlet: These ports facilitate the entry and exit of oil, ensuring smooth filtration through the filter element.
Fixing Devices: Components like screws and clips secure the filter element within the shell, preventing movement or detachment during use.
V. Special Design
Smart Sensors: Some high-end hydraulic filter cartridge oil filters are equipped with smart sensors that monitor the dirt level of the filter element. When the filter becomes sufficiently dirty, the sensor automatically issues a warning, prompting the user to replace the filter element promptly.
In conclusion, the structure of hydraulic filter cartridge oil filters is complex and intricate, with each component working in harmony to ensure oil cleanliness and equipment operation. During design and manufacturing, factors such as material selection, structural rationality, and sealing performance must be thoroughly considered to optimize filter performance and lifespan.
