| Abstract: | Mechanical seal leakage is one of main faults during operation of Twin-screw Compressor.According to the characteristics and related theories of process medium,the mechanical seal structure and pattern of Twin-screw Compressor had improved design.Using the existing auxiliary system and keeping the existing sealing structure,the non-contact mechanical sealing of double reverse crossing-groove oil film has ’self-cleaning function’ which was applied to the screw compressor.The analysis of its application technology and performance was carried out,the problem of butadiene gas twin-screw compressor shaft seal leakage had been solved. |
