4-73 boiler fan product introduction
1, Y4-73 boiler through, induced draft fan can work stably in the higher medium temperature, in the case of meeting the pressure requirements, can output a large gas flow, low noise.
2, the blade placement Angle is optimized, more wear resistance, longer service life.
3. Adjustable door can be used to flexibly adjust the pressure and flow of the fan during operation. Variable frequency motor can also be selected to adjust the pressure and flow of the fan by changing the speed.
4. 4, according to different working temperature and working speed, choose to use high strength carbon steel, low alloy steel, high temperature resistant alloy steel, high temperature resistant high strength alloy steel, so that the impeller and spindle still maintain reliable strength at high temperature.
5. 5. The fan system with the nominal diameter of the impeller less than 1400mm running at normal temperature does not need additional bearing cooling device, which reduces the investment and maintenance workload of the user.
6. 6. The impeller is annealed to eliminate the internal stress of the structure generated during welding, so as to ensure that the impeller will not have contour creep and crack.
7, the impeller's weld and spindle through ultrasonic inspection, to ensure that there are no welding defects and material defects, to ensure strength. The impeller is calibrated by high standard dynamic balance to ensure the stable operation of the fan.
8, the fan accessories are complete, for users to choose configuration.
