Mechanical Seals Manufacturer In China

Hummer H4.6-3000w small wind generator is the most advanced in the world, which has four patents.

It is extreme light and small, high in efficiency–more than 0.8 of utilization ratio.

Light: wind Generator is extremely light; the weight of H4.6-3000w small wind turbines is only 60kg, including blades, hub and nose cone.

Small: The wind turbines is inside the nose cone, and the volume is only 1/6 of conventional ones.

Low in energy consumption, noise and speed-up wind speed (3m/s for 3KW).

Swift running: hummer generator runs 1.5-3 times faster than other types of generators under equal condition due to lightness, high efficiency and low resistance. As a result it can output more power than others.

Swift charging: due to high efficiency and low wind start-up, the running time of hummer generator will be longer than conventional ones, and that is why it can charge batteries faster than others.

H4.6-3000w small wind generator has obatined CE certificate and 7 patents . For more details ,pls check on our website or contact with us directly

Hummer Wind Turbines

The Hummer wind generators hydraulic tower system can be applied in erecting up and lowering down the towers automatically during the installation and maintenances of wind turbines . By means of this equipment , a crane is saved and the cost of installation and maintenance is reduced greatly .

Furthermore ,the hydraulic equipment can be used repeatedly,more practical and economic , the tower is been hot-dip galvanize and paint coating , can well anticorrosive .

Hummer hydraulic system is classified as electric mode and manual mode . The manual mode is basically used for H4.6-3000w wind generator and below models , while the electric mode is mainly for 5kw and above models

The whole system include tower ,tower base,reversing lever ,pipleline , ram , hydraulic pump .For more details , pls contact with us directly .

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.
