Induced Draft Fan Control Oil Line HU25040-22G: Maintenance Essentials and Fault Handling

Induced Draft Fan Control Oil Line HU25040-22G: Maintenance Essentials and Fault Handling

The Induced Draft Fan Control Oil Line HU25040-22G is a critical component of the fan, and its condition directly impacts the fan's operational stability. Today, we share the core maintenance essentials and fault handling methods for this oil line.

I. Key Maintenance Focus for Oil Line HU25040-22G: Three Core Defects to Check

• Leakage Defects: Focus on checking the oil pipe joints, flange interfaces, and welded areas. According to regulations, the oil system should be free of oil leaks at all points. Confirm that welding spots used flame welding or TIG welding for the root pass process.

• Wear and Deformation: Measure the oil pipe wall thickness. If wear exceeds 1/3 of the original thickness, action is required. Check the oil line for flattening or bending, particularly pipes near rotating parts, ensuring no signs of friction.

• Blockage and Impurities: Assess the pipe's flow integrity through oil flow observation and pressure testing. Simultaneously check the oil filter element and the oil tank for foreign matter to prevent impurities from causing pipeline blockage.

II. Oil Line HU25040-22G Blockage and Wear: Targeted Solutions

• Handling Pipe Blockage: First, disassemble the oil line and mark its position. Use a high-pressure washer with a specialized cleaning agent to flush the interior. For stubborn clogs, segment-by-segment cleaning can be employed. After cleaning, the oil tank must be cleaned, and the filter element replaced to ensure oil cleanliness before reassembling the pipe according to the original markings.

• Handling Wear Failures: Minor wear can be repaired by patch welding, which must adhere to the original process standards. If wear is severe or cracks appear, direct replacement is recommended. Here, we recommend Induced Draft Fan Control Oil Line HU25040-22G. Its material is compatible with the fan's working temperature and pressure, the welding process meets standards, and it effectively prevents leakage and premature wear, meeting the flow and pressure requirements of the oil station.

• Reinstallation and Testing: After replacement or repair, an oil pressure test must be performed. Ensure the oil pump outlet pressure is no less than 0.20 MPa, and the motor bearing pad oil supply pressure is no less than 0.08 MPa. Conduct a two-hour trial run without leakage or abnormal vibration.

III.  Product Advantages and Maintenance Tips

The  Induced Draft Fan Control Oil Line HU25040-22G strictly adheres to the fan's technical specifications. Its material is wear-resistant and high-temperature tolerant, and the interface dimensions are precise, requiring no extra adjustment during installation.

Maintenance Tips: Before dismantling the oil line, be sure to seal the interfaces to prevent foreign matter intrusion. After reassembly, the line must form a clear oil path with the oil station and bearing box to ensure the stability of the lubrication and hydraulic system.

Regularly performing maintenance on the oil line HU25040-22G and selecting the compatible spare parts can significantly reduce the risk of induced draft fan failures and extend the equipment's service life.
