के बारे में कंपनी की खबरें Advantages and Operating Instructions for Metal Bellow Mechanical Seals
I. Core Advantages (Compared with Conventional Spring Seals)
1. Excellent Adaptability to High & Low Temperatures
• No vulnerable components prone to failure under extreme temperatures
• Stable performance in high-temperature, low-temperature and fluctuating temperature conditions
2. Superior Axial Flexibility & Compensation Ability
• Metal bellows act as both elastic element and secondary seal
• Effectively compensates for shaft runout, axial movement and installation misalignment
3. No Clogging & Long Service Life
• No small springs that may get stuck by particles, crystals or viscous media
• Reduces frequent maintenance and replacement
4. Strong Corrosion Resistance
• Made of high-grade alloys (Hastelloy, Inconel, stainless steel, etc.)
• Suitable for corrosive, toxic and hazardous media
5. Zero Leakage & High Reliability
• Integral welded structure minimizes leakage points
• Ideal for flammable, explosive and environmentally sensitive fluids
6. Wide Pressure & Speed Range
• Performs well in high-pressure and high-speed working conditions
• Maintains stable sealing under variable working loads
II. Operating Instructions
1. Installation Requirements
• Keep sealing surfaces clean and scratch-free
• Ensure concentricity of shaft and sealing cavity
• Tighten fasteners evenly to avoid distortion
2. Media Compatibility
• Select appropriate bellows material according to medium properties, temperature and concentration
• Not recommended for media causing severe erosion or rapid crystallization
3. Start-Up & Operation
• Run-in at low speed and pressure before full operation
• Avoid dry running, which may cause overheating and damage
• Maintain stable lubrication and cooling conditions
4. Maintenance & Inspection
• Regularly check for leaks, abnormal noise or vibration
• Inspect bellows for cracks, deformation or fatigue damage
• Replace worn sealing faces and gaskets in a timely manner
5. Storage Conditions
• Store in dry, dust-free environment away from direct sunlight
• Prevent collision or compression that may deform the bellows
