How do you know if the quality of the fan is good? In this fan application industry, not only to seriously consider procurement, but also in accordance with the provisions of the use. If the operation error of the centrifugal fan is related to personal safety, safety and production is in order, but the structure of the centrifugal fan is very complex, the key is the air inlet. Electric air valve. Fan Blades. Motor. The vent is composed of. Under different circumstances, the effect of centrifugal fan is not the same. How Do I get the centrifugal fan in good condition? First, it is a mechanical device that uses incoming chemical energy to raise the gas pressure and transport the gas side by side. This is a kind of driven fluid machinery. The gas accelerates through the high-speed fan impeller and then decelerates. Change the flow of mechanical energy into gravitational potential energy.
Now let’s see how to adjust?
Centrifugal fan needs motor rated power refers to the centrifugal fan inlet and outlet pipeline gate valve under the necessary load closed, centrifugal fan operating current exceeds the rated voltage.
Up and down is the adjustment method of centrifugal fan, proper adjustment can improve the efficiency of centrifugal fan. Improve People’s productivity. In order to ensure personal safety, the use of centrifugal fan, normal maintenance can not or lack of appropriate adjustment, learning appropriate adjustment can be stronger work, how to know the good quality of the fan? Looking for qualified manufacturers, centrifugal fan dedicated to axial flow fan and centrifugal fan products of the market sales and service projects solutions.
The centrifugal fan allows the motor to start at rated power or at reduced voltage. When the motor rated power start, rated voltage about 5-7 times the rated voltage. The step-down starting torque is proportional to the square meter of working voltage. When the power grid capacity is insufficient, should choose the step-down start.
During trial operation, check whether the connection mode is the same as the same connection mode, and check the working frequency of the centrifugal fan switching power supply. Whether the capacity of distribution components meet the requirements, whether the switching power supply phase or the same position.
During the trial operation, two people up and down, each operation of switching power supply, observe the centrifugal fan operation, immediately shut down to check abnormal phenomenon.
Four. When the two-speed centrifugal fan is in trial operation, start the low gear first to see if the direction of rotation is appropriate.
When the centrifugal fan exceeds all the normal transmission ratios, the input current of the centrifugal fan should be measured and the running current should not exceed the rated voltage. If the rated voltage is exceeded, check the working voltage of supply and demand balance.
