Timer controller is a pulse jet control device that is a main control device in a jet dust-cleaning system of a pulse bag-house. It outputs driving electromagnetic pulse valve, to control compressed air, to jet dust on the filtration bag in a proper sequence, and to keep the operation resistance to clear dust within the set range, so as to guarantee the processing capability and dust-Collection efficiency of the baghouse.
The control device creates driving voltage output every time. One driving voltage has duration, called a pulse width. The interval time between the two-interfacing output-driving voltages is called as pulse interval. The time necessary for the control device to complete electromagnetic valve outputs of all bits is called as pulse cycle. Pause time between the two pulse cycles is called as cycle interval.
