The progress and development of vortex blower
Abstract: industrial pressure blower exclusive NSK/SKF bearing steel, more outstanding, more suitable for long term non-stop operation, a top two domestic machine using high-pressure fan blade design industry; the best angle, let our volume larger, higher wind pressures; leaf independent Taiwan high pressure blower humanized connecting disc for you, even in the direct extraction of waste, can also avoid the direct damage to the bearings.
Vortex blower adopted the German air force technology, even if the wind is squeezed to operate freely, to please with runtime wind pressure small situation; unique air inlet silencing cotton design, let the wind machine to run our more quiet!
First of all, a high pressure blower with blowing and suction double function, most of the time, all can be done in one machine, can use suction, can also use the hair dryer. There is a high pressure blower less oil or oil-free operation, the output air is clean, use in our daily life is also very much.
Secondly, we want to know is, high pressure air relative to the centrifugal fan and middle fan, the pressure is much higher, often more than a dozen times centrifugal fan, which shows high pressure fan function is quite complete. If the pump body is integrally cast, but also the use of the earthquake to install the feet, then it to the installation requirements are very low.
Finally, that is to say, a high pressure blower can be maintenance free use, loss of it is only two of a bearing, in the warranty period, basically do not need maintenance, while the mechanical wear of high pressure fan is quite small, and most of all, it is easy to install, use more convenient.
At present, high-pressure vortex blower are mostly used for industrial production, is widely used in environmental water treatment, such as the sewage aeration, in order to meet the need of the aerobic microorganisms in activated sludge wastewater with activated sludge oxygen and full contact mixed conditions, and degradation of various organic matter to the purification of wastewater, but also the function of mixing, and the plating bath stirring, aquaculture, all have the same effect.
With the era of progress and development, people are not satisfied with the pressure and volume of centrifugal pump and centrifugal pump, requirements, noise also has become the factory internal headache. So, Japan launched the first full closed type flow measurement type fan, also is the high pressure fan now (vortex vacuum pump). Compared with its fine appearance and noise, for the first time to meet the demand for high pressure fan at that time society. Later, after the fan to upgrade, has developed to single, double section, three section high pressure blower impeller, and the maximum pressure in the high pressure fan once refresh to 230kpa, but only as the ultimate pressure fan.
Extensive use of vortex blower, various devices have a standard process for its operation, through a large number of experimental data we know that the exhaust pressure of high-pressure blower (vacuum) increased, high pressure blower flow decreased, shaft power increases, the total efficiency curve of a parabola, and has a high point. High pressure fan curve diagram, see the high pressure fan efficiency in the positive pressure air supply conditions is low it is clear, the highest efficiency is only 44%, but the efficiency is lower in the high pressure blower suction conditions, the highest efficiency is only 32%, so sometimes the high pressure fan can be used as a rough vacuum generating device.
