The overall development direction of Chinese fan industry (3)
From;    Author:Stand originally
3, implement science and technology hard development is new span
(one) the current situation of fan industry and difference
(1) the current situation
① main product reachs technical level
1) the centrifugal type compressor of structure of horizontal analyse cent, approach the advanced level of world congener product, little part product reachs world advanced level.
2) centrifugal type compressor is much axis isotherm international 80 age level.
3) gear assembly type is centrifugal compressor is international 90 age level.
4) centrifugal type air-blower is odd axis high speed international 90 age level.
5) the advanced level that the axis spreads type compressor to be close to world congener product, little part product reachs world advanced level.
6) the centrifugal type air-blower of general use is international 80 age level.
7) the advanced level that Luo Ci air-blower approachs world congener product.
8) boiler beat brings fan to be international 80 age level.
9) the power station moves Xie Ke to move an axis to shed type fanner to be international 80 age level.
10) child midday quickens fanner to be international 90 age level.
11) inclined shed fan to be international 90 age level.
12) mine axis sheds fanner to be international 80 age level.
Ability of fan of form a complete set of equipment of ② great technology
1) can be produce per year carbon dioxide of form a complete set of plant of 52 tons of urea centrifugal type compressor
2) can synthesize gas, air and ammonia to produce per year form a complete set of plant of ammonia of 300 thousand tons of synthesis refrigerant and centrifugal compressor
3) can enrage to produce per year splitting decomposition of form a complete set of plant of 300 thousand tons of ethylene, ethylene and propylene are centrifugal type compressor
4) can be produce per year rich energy of life of form a complete set of device of 3 million tons of catalytic cracking centrifugal compressor
5) can divide air of device form a complete set for sky of 30 thousand M3/h centrifugal compressor
6) can be form a complete set of 1000 M3 blast furnace centrifugal type and axis shed type compressor
7) can be 30~60 matched stack of electric machinery of fire of 10 thousand KW covers large shaft to flow or centrifugal type fanner
8) can be air-blower of aeration of form a complete set of device of sewage disposal of 1 million M3/d
(2) difference
Ability of form a complete set of equipment of ① large technology needs to rise further
As the accretion of petro-chemical, metallurgy and power plant dimensions, fan capacity also incline to is large change. If ethylene plant already amounted to 45~78 10 thousand tons / year, synthetic ammonia plant already amounted to 680 thousand tons / year, device of catalytic cracking of unit oil refining already amounted to 60 million tons / year, firepower generates electricity dimensions already achieved 60~130 myriad to cover with tiles. These high capacity fan remain at fan industry each enterprise is developed.
