Steam turbine seal bush (oil seal bush) is a critical sliding sealing component installed at turbine shaft ends. It forms an oil film sealing structure with the rotating shaft to prevent outward leakage of lubricating oil and avoid steam intrusion into the oil system, protecting the safety of bearing and lubrication system.
We provide fully customized manufacturing services of turbine seal bushes applicable to large thermal power turbines, small & medium industrial turbines, waste heat turbines and generator sets. We produce split-type seal bushes and integral seal bushes. Optional Stellite alloy hardfacing can be implemented on the sealing working surface to improve wear resistance and anti-erosion performance. Our products support new unit assembly and overhaul spare part replacement.
Cast tin bronze, aluminum bronze, 42CrMo, 25Cr2MoV, stainless steel and other alloy materials. Material selection matches unit operating temperature, shaft linear speed and lubrication medium requirements.
Strictly control inner hole cylindricity, split surface fitting clearance and oil groove dimensional accuracy. Ensure stable oil film formation during operation, effectively eliminate oil leakage risk.
Reasonable material matching. For units with harsh operating conditions, Stellite hardfacing can be adopted to enhance high-temperature friction resistance, resist shaft abrasion and extend service cycle.
Custom design and processing according to customer drawings: different inner/outer diameter, split structure, oil groove layout, mounting flange form. We also provide targeted optimization schemes for on-site oil leakage faults of old units.
Complete raw material test reports, heat treatment documents, dimensional inspection records and NDT certificates can be provided. Comply with power industry equipment manufacturing standards.
Suitable for high & low pressure shaft ends of large turbines, as well as small waste heat turbines, back-pressure turbines and generator bearing sealing systems.
