The Industrial Revolution in Britain brought about earth shattering changes in people's lives, and the invention and application of the steam engine led to the rapid development of manufacturing and metallurgical industries. Fans are also important equipment in these industries. Over the years, technicians have made various improvements and updates to wind turbines with the aim of achieving environmental protection, reducing noise, and lowering energy consumption. The focus of enterprises in selecting wind turbines is precisely the goals that technical personnel need to achieve. So when choosing a fan, the first direction to lock in is environmentally friendly models, such ashigh-pressure blowerAfter selecting the model, it is important to pay more attention to the operation to maximize the efficiency and lifespan of the fan.
In this article, we will mainly explore the advantageous measures of fans in eliminating noise.
*Reduce the relative acceleration coefficient of the airflow at the blade inlet and lower the vortex noise of the fan. Secondly, adopting a reasonable geometric dimension between the impeller outlet and the volute tongue, as well as a reasonable volute tongue shape, can reduce the alternating force between the impeller outlet airflow and the volute tongue, as well as the changes in airflow density caused by the shedding of vortices on the object surface, thereby reducing the noise of the fan. Thirdly, when designing the regulating valve, a reasonable number of guide vanes should be used to minimize the frequency of the impeller and the inlet regulating valve. Fourth, add a muffler to the air supply fan. Fifth, add soundproof wrapping to the fan casing.
In addition, there are many operations during the installation and use of fans that can reduce noise. The motor current of the high-pressure fan in operation is proportional to the vacuum degree and pressure index, and excessive current can directly cause the contactor to trip. Users should increase the cross-sectional area of the fan outlet or install a wind pressure and air volume control valve on the suction or exhaust side of the fan without causing detachment. The specific operation method is as follows: the inlet for air supply must be equipped with a filter that meets the actual usage situation, and the total cross-sectional area of the air outlet of the fan equipment should be greater than half of the outlet cross-sectional area of the equipment. If encountering the situation of air supply in water, the water depth pressure during the operation of the fan should be maintained below 70% of the maximum static pressure value marked in the equipment model catalog. When the fan is pressurized for air supply, if the outlet temperature of the equipment is higher than 10 degrees Celsius above room temperature, it is within the normal operating range. Air friction is the main reason for the temperature rise, so iron pipes with a length of more than one meter should be selected. A silencer should be installed at the outlet of the fan for suction, ensuring that the total cross-sectional area of the suction hole of the equipment is more than half of its inlet cross-sectional area. Proficient in cleaning the fan filter. Gently unscrew the self rotating joint of the device filter, and then use an air gun or brush to remove dust and dirt from the filter screen.
