Product Description

High Speed & High Efficiency Impulse Steam Turbine

The QNP steam turbines` capacity mainly covers 200MW and below, include NI series (Normal Impulse Turbines) and HE series (High Efficiency Turbines). Our Steam Turbines are flexible and diverse in structure and layout so as to meet various requirement of our users. Aiming at the global leading equipment manufacturing enterprise, our design and R&D standards are higher than GB standard and in the same league with European and American energy equipment manufacturers.


Characteristics of QNP Turbine:

  • High speed, high efficiency, low energy consumption
  • Highly integrated three platform and one station, require smaller space
  • In-the-factory assembly and whole machine transportation make site installation easier, faster and more economical.
  • Single-tier and direct exhaust, condenser floor installation, lower construction cost.

Technical characteristics of parts

Gland sealing matching: the industry-leading and advanced gland sealing structure design reduces the steam leakage loss.
Blade assembling: the optimized blade molded lines are designed by the international advanced design software and processed by high-grade, high-precision and advanced technology which improve the thermal efficiency greatly.

Governing system: advanced governing methods are used for high control precision and fast response speed and which also has the electronic over-speed trip function, load shedding trip function, as well as auto start, grid connection and on-load function.


Rotor: we have shrink-on rotor and solid forging structure rotor which are all processed by Mitsubishi Planer machine and adjusted by vacuum high speed dynamic balancing machine to make sure the vibration of each position of bearing is in good state when the Steam Turbine running. Small vibration of the rotor we produced is a distinctive characteristic of our products.

Condenser: the stainless steel screwed pipe is used as heat exchanger with good anti- pollution ability and high heat-exchange efficiency. High-quality titanium tube is used when the cooling water is seawater. We use digital controlled lathe for drilling hole.


Casing: the split is processed by one-off molding technology and the precision of which can be 0.0058MM without any steam leakage. The concentric circles of the whole axis are processed by high precision turn-milling of the 5-joint axis machining center.


Diaphragm: we use qualitative carbon steel as the support and make the flow field better comply with the design via special welding technology so as to improve the internal efficiency.

Lubricating oil system: the multiple filtration technology--impurity strainer of oil tank, double bucket strainer for refined filtration, bearing inlet strainer which can be replaced during running--make the turbine oil entering the bearing bush achieve the best performance.

Control and protection system: QNP uses the Siemens microprocessor as the core of the system to ensure the stability and timeliness of signal processing. For important signal, multistage redundancy functions are introduced to ensure the safe and stable operation of equipment. Friendly interface makes operator work easily. More than 3-monthes` record of operating data can be saved by recording system and also can be extracted at any time.   


Various layout and application


Except the general double-tier layout structure, we also developed steam turbine with single-tier and fast-installation layout structure, mainly includes:
 
(1)Oil tank as base plate:


Oil tank as base plate

The position of oil tank for Condensing Steam Turbine can be designed under the steam turbine as the base plate with the steam turbine, bearing pedestal and gear box on it which has same horizontal plane with condenser.

(2)Three platform and one station steam turbine:



Three platform and one station steam turbine

Composed of steam turbine base plate, auxiliaries base plate, control base plate and centralized oil station for a convenient installation and layout at site. And the centralized pipeline will let the site more clean and tidy.

(3)Axial exhaust type
Axial exhaust type
Mainly applied in 15-50MW condensing and pumping condensing high efficiency turbine. This type of steam turbine adopted single-tier arrangement, with axial exhaust directly into the condenser. Suitable for whole machine delivery, and can considerably shorten the installation period and reduce civil engineering costs.

Manufacture & Test



Project Cooperate With Us:

  • QNP, in cooperation with the Chinese Academy of Sciences (CAS) has adapted it's evaporative cooling technology for cooling of distributed energy Generators, which has reduced the size of Generators significantly.
  • In collaboration with Sea Water Desalination Institute of State Oceanic Administration, QNP has formed a technical team to carry out research on the key technologies of power generation and sea water desalination.
  • QNP has set up a training mechanism for senior managers with Tsing Hua University and Peking University, as well as technical trainings with Xi`an Jiaotong University, the Huazhong University of Science and Technology, and Shandong University in multiple fields.
  • The rapid development of QNP has captured the attention of the Fortune Global 500 companies, such as the M AN Group from Germany, and Mitsubishi Heavy Industries from Japan. These companies and numerous others have worked with QNP for technical exchanges.
  • QNP has also gotten strong support from central and local government. Top government officials at all levels have visited QNP many times and given high ratings on QNP`s development.
