Product Description
RODUCT DESCRIPTIONSteam turbine is a kind of power equipment that converts steam heat energy into rotary mechanical energy. It is most commonly used to drive generators to generate electricity and can also replace electric motors to directly drive pumps, fans, compressors and other shaft rotating equipment. According to the thermodynamic system, steam turbines are mainly divided into backpressure type, condensing type, extraction condensing type, extraction backpressure type, etc. The backpressure/extraction backpressure type steam turbine has the relatively simple thermodynamic system, there is no phase change of steam turbine exhaust steam in the system and will trans to the next heat exchange process directly by pipeline, it is the core equipment in high-efficiency cogeneration projects. In other words, these two kinds of steam turbine generator unit are the device that uses the pressure difference between the boiler and the heat supply to do power generation. It has met the heat supply demand as the primary function, and power generation exists as an auxiliary energy-saving function.
According to the rating of inlet steam parameter, the steam turbine also canbe divided into hi-temperature & hi-pressure or hi-temperature & ultra-high pressure type, medium temperature & medium-pressure type, low parameter type. These two types of steam turbine are widely use in industries included paper mills, sugar mills, printing and dyeing mills, chemical industry, petrochemical industry, food stuff industry, etc. that need a lot of heat energy consumption.

High Efficiency Ratio - The steam turbine mostly designed to multi-stage small enthalpy drop impulse type, generally have 2 to 4 stages more than traditional design models: this design arranged more stage and reduced the distance between each flow stage by adjusting the distribution of enthalpy drop, by decreased impeller diameter and increased blade height in each stage of steam turbine to reduce the interstage losses; also optimized the design of the blades, nozzles, and diaphragm nozzles profile, effectively reducing the frictional heat loss of the steam turbine, thereby improving the thermal-mechanical conversion efficiency (internal efficiency) of the steam turbine. The actual operating steam consumption rate is relatively lower, and the internal efficiency is at least 5-10% higher than traditional design models.
Wide Governing Range - The governing stage of steam turbine adopted a step-by-step regulation method to make the inlet regulation range of steam turbine more widely, and more suitable for variable operating conditions and overload operation of steam turbine.
Lower Vibration Value and Noise Level - The final rotor assembly of the steam turbine is a rigid solidly forged with CNC precision machining rotor. Compared with traditional flexible assembly rotors, the operating vibration value & failure rate of our products are significantly lower than other manufacturers' traditional models. The vibration value of the bearing pads of our units that have been put into operation are all within 0.02mm, and noise under 80dB by 1 meter distance away from the unit.
Less Steam Leakage- The steam chest & casings of the steam turbine are integrally cast and formed, the structure optimized design as horizontal split overall spherical structure is more reasonable and compact, with uniform thermal expansion and less deformation that cannot cause steam leakage on the horizontal split of the casings; The shaft gland seal system adopts axial flow labyrinth type with expansion compensation device, combined with the patented design of a reverse pressure steam seal compensation device, which has advantage of low friction on the main shaft, and steam leakage during operation have reducted more than 50% compared to traditional models, it greatly improving the safety and economy of unit operation.
More Safety & Sensitive For Governing System - Digital Electro-hydraulic Control governing (DEH) and emergency trip system (ETS) adopted separate high-pressure wear-resistant (flame resistant) oil supply system (EH), it has the characteristics of sensitive response, good stability, and low failure rate. Compared to regulation and crisis security system with low-pressure lube-oil supply, the actuator has high pulling force with high adjustment accuracy and is not easy to jamming, ETS has fast emergency trip response speed, this application eliminates the hidden failures of control hydraulic oil system caused by water emulsification and deterioration in the shared lubricating oil system.
Quickly Start-up - The high-temperature high-pressure and high-temperature ultra-high-pressure units adopt casing sleeve design of high-pressure inner casing and outer casing, this application can adapt thermal expansion of casing under startup, shutdown, and variable operating conditions, so the warm-up speed of the unit is fast, and the startup time can be reduced by more than one-third compared to traditional single casing models, greatly reducing the steam consumption during the startup of the steam turbine, thus reducing the operating cost of the unit.
Low cost of construction and operation - Due to compact structure, modular design, and small volume weight, the unit also has advantage of convenient installation and maintenance with low cost on construction & operation. TECHNICAL FEATURES
