In order to make the air pressure and volume of high-pressure blower reach a certain target value, it is necessary to control the blower and pipe network manually, also known as regulation. Through effective adjustment, the blower can ensure stable working conditions, meet the requirements of production flow, and achieve large energy saving. Customers choose different adjustment methods, the same goal, but the effect is different.
There are three designs for high-temperature exhaust fans. Smoke exhaust and ventilation set up a system, a second smoke exhaust and ventilation system, a third use of induction fan exhaust system and smoke exhaust system. After choosing these three schemes, the wind volume is calculated. The exhaust time is 6 times, and the ventilation time is the air volume needed to eliminate the harmful substance concentration. Specific calculation methods include standardized course inspection. After calculating two air volumes, take the large value as the calculation air volume. Then there is the choice of smoke outlets and exhaust outlets. Generally speaking, choose the plate type smoke outlet HTF fire high temperature smoke exhaust fan. And Square diffuser exhaust.
Now pipes, vents, smoke outlets, total tension, total air volume have, according to the total tension and air volume to choose the fan. After selecting the model and specifications, there are some data, such as wind speed and diameter. Calculate the air volume of a single outlet. The total air volume divided by the air volume of a single outlet is the number of exhaust and exhaust outlets. The basic system has been set up. Make a sketch. Carry out hydraulic calculation, calculate the diameter of air duct. Identify adverse circuits. Determine the resistance of the pipe and calculate the resistance loss. Total resistance loss and tail wind speed tension are provided by the fan dust. Special note: must follow the specifications. : select a two-speed fan. Usually shoot wind.
If the relative flow change is small (or the adjustment depth is small) , the difference between the adjustment methods is not significant. In other words, the adjustment method has no effect on the energy-saving effect, not only energy-saving, because the presence of the adjustment device consumes a large amount of electricity. The speed control curve is close to the ideal curve. Therefore, the speed adjustment method is excellent, excellent, especially suitable for the use of variable-frequency motor speed adjustment of the energy-saving program, but need to increase the frequency conversion settings. It is suggested that large-capacity high-voltage inverter should be used in small-and medium-capacity inverter because of its high price. In the normal environment, the more obvious energy-saving effect. Therefore, we should carefully choose the adjustment method to obtain great benefits.
