The manufacturing process of WU/XU oil suction filters is a comprehensive endeavor involving multiple stages to ensure the filter's performance and quality. Below is a summary of the key steps involved in the production of WU/XU oil suction filters, based on relevant information:
I. Material Selection and Preparation
Filter Media Selection: WU/XU oil suction filters typically employ high-strength filter media such as glass fiber filter paper (BN) and stainless steel woven mesh (W), renowned for their excellent filtration performance and durability.
Auxiliary Materials: Suitable housing materials, including high-strength carbon steel, stainless steel, or cast aluminum, are selected along with connecting components like pipe or flange fittings.
II. Design and Drafting
Structural Design: Based on the filter's application requirements and operating environment, a rational structure is designed, encompassing dimensions of the filtration chamber, arrangement of filter media, and locations of inlet and outlet ports.
Drafting: The design plan is translated into detailed engineering drawings, specifying dimensions, tolerances, and mating relationships of individual components, serving as a foundation for subsequent processing and assembly.
III. Processing and Manufacturing
Housing Processing: Precise machining of the housing is performed using CNC machines or mechanical processing equipment to ensure dimensional accuracy and surface quality.
Filter Media Treatment: Necessary treatments like cutting, pleating, and pressing are applied to the filter media to meet the filtration requirements of the filter.
Assembly: The processed housing, filter media, and connecting components are assembled to form a complete filter.
IV. Inspection and Testing
Visual Inspection: The filter's exterior is examined for defects such as cracks, scratches, or rust.
Performance Testing: Performance tests, including filtration accuracy, oil flow capacity, and resistance, are conducted to ensure the filter meets design specifications.
Leakage Testing: The filter's sealing performance is verified to prevent leaks during operation.
V. Packaging and Shipment
Packaging: Qualified filters are packaged to protect them from damage during transportation and storage.
Final Inspection: A final inspection is conducted before shipment to ensure product quality conforms to standards.
Accompanying Documents: Necessary documents like product certificates and user manuals are provided for user convenience and comprehension.
VI. Special Processes and Precautions
Advanced Processing Techniques: Employing advanced processing techniques minimizes filter media damage during pleating, ensuring consistent and stable filtration accuracy.
Multiple Standard Tests: Filters undergo multiple tests adhering to standards like ISO 2942:2004 to verify the absence of structural defects that could compromise filtration accuracy assessments.
Rigorous Quality Control: A stringent quality control process spans raw materials, semi-finished products, and finished goods, with 100% inspection of outgoing products to guarantee superior quality.
In conclusion, the manufacturing process of WU/XU oil suction filters is intricate and meticulous, requiring rigorous control over every stage to ensure product performance and quality.
