2. Multi-model Adaptation, Strong Scene Versatility
   It covers a full range of models including back pressure type, condensing type and extraction condensing type, which can operate for pure power generation or realize cogeneration and waste heat recovery power generation. It can meet the centralized power supply needs of large power plants, as well as small and medium-sized working conditions such as factory self-provided power stations, waste heat utilization and steam pressure reduction power generation, with models customizable according to users’ steam parameters and power load.
3. Intelligent Automatic Operation, Simple Operation and Maintenance
   Equipped with a full-automatic PLC intelligent control system, it supports one-key start and stop, automatic speed regulation, voltage and frequency stabilization, and automatic load adjustment. It can monitor core parameters such as unit temperature, pressure, speed, vibration, current and voltage in real time. With functions of self-fault diagnosis, over-limit alarm and automatic shutdown protection, it does not require full-time on-duty personnel, greatly reducing manual operation and maintenance costs and ensuring safe and controllable equipment operation.
4. Precision Structural Design, Stable Operation and Long Service Life
   Core components such as steam turbine rotors, blades and bearings are made of high-strength alloy materials, through precision processing, dynamic balance correction and non-destructive testing, featuring strong vibration resistance, low wear and no easy deformation. The whole machine has an excellent sealing structure with low steam leakage rate and stable lubrication of the bearing system, which can operate continuously at full load for a long time with low failure rate and long service life.
5. Energy Saving and Environmental Protection, Comply With Green Production Standards
   Based on the principle of waste heat recovery and cascade utilization, it maximizes the recovery of industrial waste steam and waste heat resources to turn waste into energy, effectively reducing enterprises’ external power purchase costs. The unit operates with low vibration, low noise and compliant emissions without secondary pollution, fully meeting the policy requirements of industrial green production, energy saving, consumption reduction and low-carbon emission reduction.

Material & Core Process

1. Turbine Core Material
   The rotor and blades are made of high-temperature, high-pressure and fatigue-resistant alloy steel, which is resistant to high-temperature creep, high in strength and good in toughness, and not easy to be damaged during long-term high-speed operation; the cylinder is made of high-quality cast steel with excellent pressure bearing performance and strong sealing, suitable for high-temperature and high-pressure steam working conditions.

2.Power Generation System Process
The generator adopts full-copper winding with high insulation grade and optimized heat dissipation structure, featuring low temperature rise, low loss and high power generation efficiency. The stator and rotor are precisely laminated and formed with high dynamic balance accuracy, no jitter during operation and stable voltage output, suitable for long-term grid-connected and independent power supply working conditions.

3.Sealing and Lubrication Process
Adopting a multi-stage labyrinth sealing structure with high-end sealing fillers, it effectively blocks steam leakage and reduces thermal energy loss; the circulating lubrication system has high filtering precision and stable oil supply, which continuously cools and reduces wear for bearings and transmission components, ensuring long-term stable operation of the unit.

4.Inspection and Calibration Process
The whole machine undergoes dynamic and static balance test, water pressure test, air tightness test, insulation test, no-load and full-load trial operation before delivery, with all parameters precisely calibrated. Vibration, temperature rise, noise, voltage and frequency all meet the standards, eliminating hidden operational faults.
