Selection points of suction fan for dust collector equipment :
1: Before selecting the suction fan of the dust collector equipment , we must know the current product and product quality of the domestic suction fan, such as the manufacture of suction fans and various types of products and various uses, and some manufacturers' products Quality, after-sales service and other situations and inspections.
2: According to the type of gas transported by the suction fan, there are different suction fans used in the selection. For example, if it contains explosive and flammable gases, you should choose an explosion-proof suction fan; choose a pulverized coal suction fan in the industry that transports pulverized coal; choose a suction fan with anticorrosive properties for gas with corrosiveness; Should choose a suction fan that can adapt to high temperatures.
2 种以上的吸风机可让我伴们选择时，我们应该先选择效率套机号较小、在调节上范围比较大的一种。 3: For the dust removal equipment , there are more than two types of suction fans on the chart of the function of suction fan selection. When our companions choose, we should first choose the one with the smaller efficiency package number and the larger adjustment range.
75kW 时，可以不设启动用的阀门。 4: When the motor power of the suction fan of the dust collector equipment reaches ≤ 75kW , there is no need to set a valve for starting. When transporting high-temperature soot and selecting a centrifugal boiler induced draft fan, a valve for starting should be installed to prevent overload during cold operation.
5: In the exhaust system that requires the muffler, the suction fan with low noise should be selected first, for example, the suction fan with higher efficiency and the impeller has a round speed, so that the machine can operate at a high efficiency point, and the relative muffler can be used Method, such as installing professional muffler equipment.
6: When selecting the suction fan, the dust removal equipment factory should not use the action of the suction fan in series or parallel as much as possible. 1 级吸风机到第 2 级通风之中应该有一定相同的的联结管路。 When the suction fans are operated in combination, different models and specifications of suction fans can be used in parallel and in series to work; when used in series operation, the first -stage suction fan to the second -stage ventilation should have the same connection pipe.
7: When the suction fan of the dust collector equipment needs to be replaced, we should pay attention to the use of previous equipment, suitable on-site installation and operational safety, etc. The previous operating conditions and existing problems of the original fan are used to determine the design and Parameters to prevent the air volume and resistance required to install the new type of suction fan and not meet the current actual air volume requirements.
