Abstract
PURPOSE:To minimize the pressure loss of filter and the operational power of fan and to eliminate the useless electric power consumption by controlling the number of revolutions of motor so that the measured flow rate is to be within a set air flow rate and keeping the air flow rate passing through a dust collector being constant. CONSTITUTION:After the revolution of the motor 3 is started and reached to a specified number of revolutions, a suction fan 15 is started in operation. In this state, the practical air flow is measured by a flow rate sensor 2 to compare it to a set air flow rate in a flow rate calculating, indicating and setting device 5 from which the calculated output is sent to a central processing unit 8 to determine whether the measured flow rate is within the set air flow rate or not. If the flow rate is within the set value, the revolution of a motor 3 is kept as it is, and if the flow rate is larger than the set value, the revolution of the motor 3 is controlled through a revolution control device 6. If the flow rate is smaller than the set flow rate, it is judged to be the clogging of a filter 14, and a direction is outputted to a dust removing control unit 7 to operate a dust removing device 9 during the period of specified count.
