VENTILaTION : PULLEYS

The actual resistance of ductwork systems is not always identical to the calculated theoretical values. To rectify this, it may be necessary to modify the pulley and belt setting. To this effect, the motors are fitted with variable pulleys. AIRFLOW BALANCING Measure the absorbed amps If the absorbed…

CHECKING AIRFLOW AND ESP

2nd method when adjusting the pulley : -Close the pulley fully and count the number of turns from fully closed position. Using table 1 determine the motor pulley actual diameter. -Determine the fan speed using the following formula: Using the fan curves on page 25, 26, 27, the airflow, the total…
