Explosion-proof electric fan company _ _ Kaka proof fans

 Overview of the company with 20 years of professional experience in research and development of dedicated special fan in the full investigation and fieldwork basis Beijing, Shanghai, Hong Kong and other overseas subway ventilation system on proof axial fan manufacturers, joint Beijing University of Aeronautics and Astronautics, Shanghai Jiaotong University, the use of China Aerodynamics Research and Development Center experimental test mechanism Institute of China Aviation Gas Turbine Laboratory studies and, through a large number of fans and the passage vortex system test, the fans build digital models, repeated operation, designed to maximum minimizes the harmful tip vortices at the blade root, in order to achieve high efficiency, low noise, compact structure, reliable operation purposes. On the basis of absorbing international advanced technology, but also by domestic subway explosion-proof fans, tunnel expert institute enthusiasm to help, guidance, and the successful development of high-quality, subways, tunnels dedicated fan. Now DTF (R) (R) series fan (TVF fans) have been identified by national experts and users practical application of proven, high-efficient, low-noise, Reversible switching time is short (), high temperature (by the national testing center detection qualified), compact structure, smooth running and other notable features, experts agreed that has reached the international advanced level. Shangyu fan and also the introduction of a random variable pressure specially developed new technology fan leaf angle and anti-surge means new products to further meet the requirements under the subway, tunnel-specific conditions. Applications tunnel axial fan is mainly used for subway ventilation, ventilation can be used for railway tunnels, mountains and underground engineering and buildings, is a high-pressure, low noise, high efficiency axial fans. For still no dedicated fan of the series, but the status quo thriving underground engineering construction and the need to import large quantities, using advanced CAD system software, designed by the multi-objective optimization and general domestic Underground Construction, subway tunnels matched leaf type and machine number, its technical performance indicators have reached or part than similar foreign products. M such notice with squirrel-cage induction generator directly connected to the grid, the fan rotor through a gearbox and generator connected as shown in Figure 8-6, the Danish wind power technology is the core technology of manufacturing technology. The advantage of the fan is simple and reliable regulation, the control system can greatly simplify, when the stall effect works, without the use of the control system; big disadvantage is that the blade mass (with the variable pitch fan blades than W, wheel Yi, tower, etc. member by the force increases. stalling effect is complex dynamic process, it is difficult to accurately calculate the wind speed under unstable conditions, and thus a long period of time is considered not available for a large reward movable hair. Teow type and medium 'Peng Well! Tired of experience so that designers can more reliably calculate the stall phenomenon, but still avoid using Mw 9- dynamic stall effects. (2) That the reclining pitch regulated wind turbine with variable pitch means mounted on the wheel Yi leaves, you can help control the pitch angle change its method of adjusting the size of their divided into three stages: the first stage of the boot stage, when the fan reached operating conditions, a computer command to adjust the pitch angle of the pitch angle adjustment. to 450, when the speed reaches a certain time, and then adjusted to 00, until the fan to rated speed and power generation; the second stage, when the output power is less than the rated power, the pitch angle remains unchanged at 00 positions; the third phase explosion-proof fans installation diagram, when the generator output power rating, adjust the system is put into operation, when the output power changes proof axial fans, timely adjust the size of the angle of pitch, when the wind speed is higher than the rated wind speed, the output power of the generator base unchanged.
