Dongguan Quanfeng Environmental Protection Equipment Co., Ltd. tells you how to select a high-pressure blower:
1) Before choosing a high-pressure blower, you should understand the production and product quality of domestic high-pressure blowers. For example, the varieties and specifications of high-pressure fans produced, the special uses of various products, the development and promotion of new products, etc., the requirements of environmental protection should also be fully considered in order to select the best fans.
2) When there are more than two types of high-pressure fans to choose from on the high-pressure fan selection performance chart, you should give priority to the one with higher efficiency and smaller machine size: the one with a larger adjustment range. Of course, they should be compared and decided after weighing the pros and cons.
3) According to the different physical and chemical properties of the gas transported by the high-pressure blower, select high-pressure blowers for different purposes. If you want to transport explosive and flammable gases, you should choose an explosion-proof high-pressure fan; if you want to remove dust or transport pulverized coal, you should choose a dust-exhaust or pulverized coal high-pressure fan; if you want to transport corrosive gases, you should choose an anti-corrosion high-pressure fan; when working in high-temperature situations or To transport high-temperature gas, high-temperature and high-pressure fans should be selected.
4) If the diameter of the selected fan impeller is much larger than that of the original high-pressure fan, in order to use the original motor shaft, bearings and supports, the motor starting time, high-pressure fan must be adjusted The strength of the original components and the critical speed of the shaft are calculated.
5) When selecting a centrifugal high-pressure fan, when the motor power it is equipped with is less than or equal to 75KW, the valve only for starting is not required. When a centrifugal boiler induced draft fan is selected to discharge high-temperature flue gas or air, a starting valve should be installed to prevent overloading during cold operation.
6) When selecting high-pressure fans, try to avoid using high-pressure fans working in parallel or in series. When unavoidable, high-pressure fans of the same model and performance should be selected to work together. When using series connection, there should be a certain pipeline connection between the first-stage high-pressure fan and the second-stage high-pressure fan.
7) For ventilation systems with noise reduction requirements, a high-pressure fan with high efficiency and low impeller circumferential speed should first be selected and made to work at the highest efficiency point; the noise generated by the ventilation system and the According to the propagation mode of vibration, take corresponding noise elimination and vibration reduction measures. Vibration reduction measures for high-pressure fans and motors generally use vibration reduction foundations, such as spring shock absorbers or rubber shock absorbers.
8) The selected new high-pressure fan should consider making full use of the original equipment, being suitable for on-site production and installation, and safe operation.
