Customized Steam Turbine Diaphragm Shroud Steam Seal Ring
Product Overview
The diaphragm shroud steam seal ring is a critical flow-path steam seal component within steam turbine sealing systems. As an inter-stage steam seal, it functions to mitigate steam leakage in non-work-expansion sections, specifically serving as part of the blade tip-root sealing system alongside root steam seals.
Installation & Structural Features
Installation Position
Mounted on the inner upper edge of the diaphragm or stationary blade carrier, facing the outer circle of moving blade shrouds or blade tip shields.
Sealing Mechanism
Utilizes multi-row teeth configuration where steam passes through sequential throttling orifices and expansion chambers, converting kinetic energy to thermal energy for step-by-step pressure reduction.
Core Sealing Functions
Reduces Inter-stage Leakage Loss: Minimizes short-circuit leakage through blade-tip gaps, improving stage efficiency and overall unit thermal economy
Prevents Steam-flow Disturbance: Ensures steam expands following designed flow paths and stabilizes internal flow-field of each stage
Accommodates Clearance Variation: Elastic retractable structure enables fine adjustment of seal segments to maintain optimal sealing clearance during operational changes
Product Advantages
Our diaphragm shroud steam seal ring features an optimized high-low tooth configuration with increased sealing teeth count for superior throttling performance. Manufactured from premium alloy steel with moderate hardness, it delivers excellent wear resistance without damaging rotor components.
High-precision spring strips provide stable centripetal force and sufficient retraction stroke
Well-suited for frequent load fluctuations in peak-shaving units
Rigorous quality inspection ensures compliance with industrial standards
Direct replacement for OEM parts improves flow-path efficiency and reduces coal consumption
