The main oil pump rotor is a critical core component of steam turbines in power plants. Its primary function is to deliver stable, reliable, and sufficient oil supply for turbine lubrication and governing systems. This component plays an irreplaceable role in ensuring long-term, efficient, and safe turbine operation, with its performance directly determining the normal operation of the entire turbine unit.
Product Features
High-Precision Manufacturing Process
Advanced CNC machine tools and high-precision machining technology ensure strict dimensional accuracy and geometric tolerances. Axial and radial run-out are controlled within extremely narrow limits, ensuring stability at high rotating speeds, lowering vibration, and extending service life. Fine surface polishing reduces fluid resistance, improves oil delivery efficiency, and mitigates local wear.
Premium-Grade Material
High-strength, high-toughness, corrosion-resistant alloy steel is selected for superior mechanical properties. The material maintains stable dimensions and performance under long-term high-temperature, high-pressure, and oil-medium service conditions, resisting deformation, fracture, and corrosion. Rigorous inspection and heat-treatment optimize internal metallographic structure, enhancing strength and toughness for safety and stability under complex operating modes.
Optimized Lubrication & Sealing Design
Optimized internal oil passages enable smooth oil flow and form stable lubricating oil films, effectively reducing friction and wear between rotor and bearings. Advanced sealing configurations such as mechanical seals and labyrinth seals deliver dependable sealing performance, preventing oil leakage, environmental contamination, and maintaining oil cleanliness.
Excellent Dynamic Balance Performance
Strict dynamic-balance correction during production achieves high-grade balance accuracy for high-speed rotation. Precision counterweight neutralizes centrifugal force, minimizing vibration and noise while enhancing overall turbine smoothness and reliability to support stable power-plant output.
Customizable Design
Custom-built main oil pump rotors are available for different turbine models and site operating conditions. Dimensions, profiles, materials, and performance parameters can be tailored to achieve perfect compatibility with customer systems and deliver optimized solutions.
Application Scope
Widely used for various steam turbines across power-generation and industrial sectors:
Large thermal power-plant turbines: Supplies steady oil for high-power, high-parameter thermal units to sustain lubrication and governing systems for efficient power generation.
Small-scale power-plant turbines: Suitable as main or standby pump rotor to secure stable equipment operation.
Combined heat and power (CHP) turbines: Provides reliable oil supply for simultaneous power generation and heat-supply, boosting overall energy efficiency.
Industrial steam turbines: Applied in chemical, metallurgical, and other industries for driving turbines to guarantee continuous industrial production.
