Core Principle of Oil-Pressure-Difference Balancing
Oil pressure difference exists between adjacent bearing housings of steam turbine units, which can lead to oil churning, oil leakage, and oil contamination. Installed on the rotor journal between two bearing housings, the intermediate oil baffle acts as the key component to balance oil-pressure difference. Equipped with a floating self-adaptive structure and multi-stage throttling passages, it dynamically diverts oil flow from the high-pressure side and buffers pressure on the low-pressure side, offsetting pressure difference step-by-step and preventing cross-flow of lubricating oil. Our intermediate oil baffle is optimally designed based on this principle and compatible with operating conditions of various units.
Key Function Pathways for Oil-Pressure-Difference Balancing
Multi-stage Throttling for Gradual Pressure Reduction
Multi-layer labyrinth throttling grooves are integrated inside the intermediate oil baffle. When lubricating oil from the high-pressure side flows through, damping effect is generated via abrupt clearance changes to reduce oil pressure progressively. This prevents high-pressure oil from directly rushing into the low-pressure bearing housing and mitigates impact caused by pressure difference.
Floating Fitting for Dynamic Pressure Equalization
The floating-type structure enables the inner ring to achieve self-adaptive concentricity with the rotor, maintaining uniform and controllable radial clearance. During pressure-difference fluctuation, the oil baffle fine-tunes its clearance automatically to balance oil pressure on both sides, avoiding oil-film rupture and bearing wear induced by excessive local pressure difference.
Oil-return Diversion for Stable Pressure Difference
Precision-made oil-return passages are reserved to divert excess oil back to the oil tank. This prevents pressure build-up caused by oil accumulation inside bearing housings, keeps the oil-pressure-difference within safe limits, and eliminates oil cross-flow, oil splashing, and oil degradation.
Preferred Solution for Pressure-Difference Balancing
Conventional oil baffles suffer from pressure-difference imbalance due to fixed clearance and poor sealing. Our intermediate oil baffle specifically addresses these issues. It adopts high-strength wear-resistant alloy featuring high-temperature resistance and oil corrosion resistance. Combined with floating labyrinth structure and precise throttling design, its pressure-difference balancing efficiency is increased by 40%. The integrated reinforced structure eliminates loosening and deformation for long-term stable operation. This solution thoroughly addresses issues including bearing-housing oil cross-flow and pressure-difference fluctuation, serving as a reliable option for unit sealing retrofitting.
Performance Advantage: 40% increase in pressure-difference balancing efficiency compared to conventional oil baffles.
