Roots Blower

First half 2008: industry fan is great, but very crowded market - fans, market analysis, Refrigeration - Air Conditioning Industry
Channel recommended: Help CVC overcome in the reconstruction
Source: Market HC Shown: in January 2008? In June, the trend Fans consistent supply and demand, except in March? In April between the supply rate slightly lower than buying more. February and May, or buy both supply peaked in February 2008 is Chinese New Year, fans of this month market operations are active in the network shows, fans also got a agreement Coach of the New Year, the markets for production, and in May of this season is the traditional sale of refrigeration, in May 2008, more manufacturers of fans, and as in previous years participation in the regular trade , as more social responsibility, the magnitude 8 earthquake makers can not stand for fans of both products are used for relief or supply, the natural tendency of showing a peak in May. However, the supply in January, March and April and demand in the hem.

Fans, including the fan, fan turbine fan and compressor turbine Roots, a detailed breakdown, including the centrifugal compressor, axial compressor, fan, centrifugal blower roots blower centrifugal fan and axial fan, etc. Yip 7 categories. Demand characteristics of the fan

include the use of ventilators for small and medium to large, the product structure and manufacturing process is relatively simple, inexpensive, user is the main pursuit of high efficiency, low noise, long life and low cost. The other is the capital and technology intensive, the structure of complex products, the production cycle is long, thorough and systematic as strong, but also in the high pressure, high temperature and high speed running condition, some even in bad condition, the user class fans have different requirements. On the turbine and compressor and blower fan large, the user is the main pursuit of high quality, high reliability, proper operation and long life.

The application of large areas of structure prediction for the general ventilation fan (usually small and medium-sized centrifugal and axial fans) the most widely used, demand is increasing, manufacturers have the most. Generally speaking, this type of oversupply of products. Special Purpose fans (including fans anti-corrosion, heat fan, fan wear, fire exhaust fan, etc.) demand, while not great, but the environment of special service, a separate treatment, because the main material has a specific need. Roots Blower The most important feature is that when the pressure in the range of allowable setting, the flow was little changed, the line pressure range of options has forced the transmission characteristics of gas, the main drawback is noisy. In recent years, thanks to the introduction of technology, joint ventures and self-development, etc., China has launched a low-noise fan lobe Roots, well received by users and market outlook. compressor turbine (including the centrifugal compressor, axial compressor and axial - centrifugal compressors) complete sets of equipment is an important facility for major projects, played an important role in the national economy. The performance of the turbine compressor to the pressure of high demand, but also flows. With the full set of aircraft size and increasingly necessary parameters of the turbine compressor. Equipment such as blast furnaces, large scale coal-chemical equipment, large-scale chemical fertilizer plant, large air separation units importantly, a natural gas pipeline to transport equipment and oil field equipment gas injection. The total demand for the products in question for fans of very few but important and complex structure, the length of production cycle, high technology, therefore, have better economic and social benefits. the level of manufacture turbine compressor represents the overall level of the fan.
