In large-scale thermal power plants, the turbine serves as the core equipment, with its rotor weighing tens of tons and rotating at high speeds of 3,000 RPM. Reliable lubrication is an absolute prerequisite for preventing bearing failure and ensuring the safe and stable operation of the unit. Within this critical lubrication oil system, the gear pump lubricating oil supply unit plays an indispensable role.
The core advantages of our SBG gear pump are highly aligned with the requirements of this application scenario:
01
Strong Self-Priming Capability
Ensures reliable suction of lubricating oil during system startup or oil level fluctuations, preventing cavitation.
02
Compact Structure and High-Pressure Resistance
The simple and robust design of the gear pump offers a small footprint while generating stable discharge pressure sufficient to maintain the required lubricating oil pressure (typically 0.1-0.2 MPa).
03
High Reliability and Easy Maintenance
Its rugged construction allows for prolonged standby periods without requiring special maintenance, resulting in a low failure rate.
04
Insensitivity to Medium Viscosity
Capable of steadily conveying high-viscosity lubricating oils.
Within the turbine lubrication oil system of a power plant, the gear pump acts as the primary backup and emergency oil pump. Its value lies not in continuous operation, but in its critical reliability – embodying the principle of "maintaining readiness over long periods to be deployed at a crucial moment." Leveraging its inherent technical characteristics, the gear pump provides the most direct and reliable lifeline for core equipment worth hundreds of millions during unit startup, shutdown, and most critically, during emergency fault conditions. It is an essential and classic component in the power plant's safety chain. Our gear pumps and Roots blowers have a proven track record of excellent performance in projects at major Chinese power plants, including China Datang Corporation and CGN Power.
