Gearboxes for Gas Turbine Power Generation

Advantage of customized service: The high-speed gearbox for combustion engines has the outstanding feature of customized design, which can be tailored to the unique requirements of different units.

Flexibility of accessory integration: The provision of a variety of accessories and integrated design according to the actual needs of this feature brings great convenience to users. For example, according to the environment of the power generation equipment and specific operational requirements, different accessories such as cooling devices, lubrication system monitoring modules, vibration sensors and other accessories can be integrated, so that the gearbox has a more comprehensive functional protection in complex power generation conditions.

High-standard quality assurance: The gearbox and its accessories fully meet the international and industry advanced standards such as API, AGMA and ISO.

High Precision Gear Process: The gears are of ISO Class 3 - 5 accuracy, which means that the gears are machined and manufactured to a very high level of precision.

Highly efficient Power transmission : with an efficiency of 98.5% or more, this high transmission efficiency is a significant advantage in the power generation process of a combustion turbine.

Smooth and low-noise operation: It has the excellent characteristics of low noise and smooth operation. In relatively quiet environments such as power plants, low-noise operation will not cause too much interference to the surrounding environment, and also indirectly reflects the good coordination between the internal components of the gear box, stable transmission.

Precise detection function: It has high-precision vibration, temperature and other system detection functions, which is the key to ensure the high reliability of the gearbox operation. Through real-time monitoring of the vibration and temperature changes of the gearbox during operation, potential faults can be detected in a timely manner, such as wear and tear of gears, poor lubrication, loose parts and other problems.

 

Reasonable center distance range: the center distance is between 200 - 1,000 (mm), which covers a wide range of specifications and sizes, and can be adapted according to the specific structural and layout requirements of different powers and types of combustion turbine generator sets.

flexible Speed Ratio Adjustment: The speed ratio range is set from 1 to 10, and such a wide range of speed ratios enables the gearbox to flexibly respond to the diversified demands for speed and torque in different application scenarios, such as gas turbine power generation, steam turbine power generation and distributed energy power generation in power plants.

Suitable speed range: The speed range is ≤25000 r/min, and this speed limit is determined based on the design performance of the product as well as the reliability considerations in practical applications.

Powerful Power Coverage: With a rated power of ≤100,000 kW, the wide power range allows it to accommodate a wide range of power generation scales, from small distributed energy generation projects to large-scale power plants.

 

It is mainly used in the fields of gas turbine power generation in power plants, steam turbine power generation in power plants and distributed energy power generation. In power plant gas turbine power generation, as the key transmission component connecting the gas turbine and generator, it efficiently and stably transmits the mechanical energy generated by the high-speed rotation of the gas turbine to the generator, which is then converted into electric energy and transmitted to the power grid to meet the demand for large-scale power supply; in power plant steam turbine power generation, it also plays an indispensable role in the transmission and ensures that the power from the steam turbine can accurately drive the generator to work, realizing stable power production. For distributed energy power generation projects, such as small gas power stations, biomass power stations, etc., the gearbox can also help these distributed energy equipment to realize efficient power generation by virtue of its flexible parameter adaptability and reliable performance, providing clean and reliable power resources for the local area, and playing an important role in the modern energy supply system.

 

Before installation, the installation site should be investigated in detail to ensure that the site has a solid, level foundation, good anti-seismic performance, and meets the installation requirements of the gear box and ancillary power generation equipment.

Before the first operation, it is necessary to carry out a comprehensive cleaning of the gear box interior, carefully check the installation of the gears, bearings, shaft seals and other key components as well as the lubrication status, and refill high-quality lubricating oil in accordance with the specified oil level and oil requirements.

In the process of operation, a perfect equipment operation monitoring system should be established, and the oil temperature, oil pressure, vibration, temperature, rotational speed and other key parameters of the gear box should be strictly tested and recorded on a regular basis, while paying attention to the overall operating conditions of the supporting power generation equipment.

For the long-term out of service or seasonal out of service equipment, the equipment should be cleaned, anti-corrosion, anti-rust treatment before decommissioning, and the lubricant in the gear box should be discharged cleanly and properly preserved. Before re-activation, the equipment needs to be fully inspected and maintained, and the preparatory work should be carried out according to the requirements before the first operation to ensure that the equipment can be safely and reliably put into operation again.
