Danish Energy Agency released the latest data show that in 2009, the Danish wind power to restore growth and full-year land-based wind power production increased by 97 megawatts (MW), the highest since 2002, offshore wind power production increased by 237 megawatt (MW).

According to the Danish Energy Agency statistics, the Danish wind turbines accounts for about 20% of the total electricity consumption. Danish Wind Industry Association has previously set forth their goal, that is, by 2020, wind power accounted for 50% of the total electricity consumption. Although Denmark has long been considered to be the world’s leading wind power technology-exporting countries, but in recent years has experienced a low growth period. Danish Wind Industry Association of the Energy Department has announced

Renewable energy is receiving increasing attention as the world attaches importance to the environmental protection and energy conservation. Among all the types of green energy, Wind power generation is a generation mode which has relatively mature technology and prospect for large-scale development and commercial exploitation. Hence it gains increasing concern and has broad development prospect.

In order to improve the market competitiveness continuously we have to pay great attention to Independent Innovation. For a long time, Hummer Dynamo Company has always attached great importance to the development,manufacture and technical services of products . For meetting much more environmental demands as well as configure suitable wind generator for customer much more flexibly, we have begun to develop the 30Kw wind generator which is more powerful than H9.0-20000w ever since May 2008,include:H8.0-10000,H2.7-500w,H4.6-3000w,H6.4-5000w ,H3.8-2000w and H3.1-1000w,we have completed the preliminary research and development work on September 2009.By the end of 2009, the 30kw hummer wind generator has been tested in-situ and achieved great success!

4) hummer wind turbines Nose Cone Protection Cover

Nose cone is made of reinforced aluminum alloy.

hummer wind generators Nose Cone Protection Cover locates in front of blades to reduce the wind resistance. The generator is enclosed in the nose cone, which is favorable for heat dispersion.

Protection cover’s made of reinforced aluminum alloy.

It is located between blades and nose cone to further reduce the wind resistance and protect the wind generator.

5) yaw shaft

It is made of superior steel to integrate blades, the wind turbines, tail pole, tail wing and tower.

Tower not only supports the wind turbine but also determines how good the wind is .Usually ,the higher the tower is ,the faster the wind blows thus more energy grasped .And the quality of the tower also effect the usage of the whole system to some extent .

We can offer guys tower ,free standing tower and hydraulic tower for wind turbines ,they with respective advantanges .

Hummer guys tower is made of steel tube ,anti-corrosion processed .Our standard height of the guys tower is from 6m to 12m ,the diameter is from 76mm to 220mm ,also can produce as customers’ demands .

And we suggest customers use guys tower in 500W to 5000w wind generator .For more details,pls check with us !

Designed for non-turbo, large – bore rotating equipment applications, the new Type 2800X dual seals feature patented new technology that provide environmentally-friendly and emission-free sealing. The 2800X seals have been created for use in a wide variety of performance-critical applications. These include the processing of extremely pure materials where no contamination is permissible, the use of reactive or temperature-sensitive media where local process ‘hot spots’ can cause unwanted chemical reactions, cold applications such as ammonia processing, and air/oxygen-sensitive processes where unwanted oxidation reactions could occur. The seals feature spiral grooves machined into the mating ring faces of the seal heads. As the pump shaft rotates a pressurised inert gas is injected between the faces and compressed as it flows into these grooves. The gas expands again as it leaves the spiral grooves and generates a force which separates the faces to create non-contact operation. This minimises seal face wear, reduces running and repair costs and extends seal life. Because the gap between the seal faces is kept to a minimum, barrier gas usage is also reduced. A reverse pressure capability ensures that if the barrier gas fails the process pressure will close the seal faces, preventing any large-scale loss of process fluid to atmosphere. The result is safer and more environmentally-friendly operation, even under breakdown conditions. The system also eliminates the need for any complex barrier fluid system, which simplifies the installation procedure. This environmentally friendly performance of the 2800X seals also translates into greater economy for the end user. Figures released by the Fluid Sealing Association show that these seals reduce the cost of electricity used and the associated greenhouse gas emissions by 92% when compared to a conventional wet seal rotating at normal pump speeds and pressures. The patented 2800X design can accommodate both lower and higher speeds and pressures than similar seals and this further extends reliability, while the use of new polymeric components reduces hang-up problems with solid-in-liquid process fluids. The various 2800X seals also incorporate many common components. This minimises spares stockholding and also encourages the re-use, refurbishment and re-cycling characteristics of the seals. The ability to retrofit the 2800X range into installations currently using John Crane 2800, 2800ER, and 2800HP seals enables end-users to upgrade their current sealing arrangements as part of their normal maintenance programmes. Included in the 2800X range are versions that meet and exceed the performance and design requirements of the latest American Petroleum Institute API 682 edition seal standard.
