                       Common problems and solutions of pulse dedusting controller

Pulse dedusting controller is the main control device of pulse bag filter. Its output signal controls the electromagnetic pulse valve to recycle the filter bag, so as to ensure the processing capacity and dust collection efficiency of the dust collector. The product's pulse interval, pulse width, output path, cycle interval can be adjusted, data can be displayed by digital tube, output path can be adjusted according to the demand. So let's talk about common problems and solutions of pulse dusting controllers.

Pulse dedusting controller is the main control device of pulse bag filter. Its output signal controls the electromagnetic pulse valve to recycle the filter bag, so as to ensure the processing capacity and dust collection efficiency of the dust collector. The product's pulse interval, pulse width, output path, cycle interval can be adjusted, data can be displayed by digital tube, output path can be adjusted according to the demand. So let's talk about common problems and solutions of pulse dusting controllers.

Three, working principle

The pulse controller adopts industrial chip as the control core. There are obvious setting marks on the printed circuit board, which can facilitate the setting of the controller; The output side of the controller is provided with working instructions for each output point, which can quickly judge the state of the output point. The controller is equipped with a manual operation button to facilitate the debugging and operation of the equipment; The output of each output control the opening of the electromagnetic pulse valve, jet compressed air to clean the ash, at the same time has led display jet sequence. When the dust collector is cleaning, the dust is sprayed while filtering. The pulse controller adopts waterproof shell structure according to the set pulse width and pulse controller, and can be used in outdoor and dust environment with waterproof connector. The pulse controller is equipped with pluggable printed circuit board terminals, which can be connected conveniently.

Pulse interval output electrical signal control pulse valve one by one jet ash.

Common problems and solutions of pulse dedusting controller

Pulse controller is one of the commonly used parts of dust collector, today we will introduce common problems and solutions in the use of pulse controller:

I. what matters to note when using off-line ash removal?

The pulse controller produced by the company provides the functions of online and offline ash removal, but when using off-line ash removal, it is necessary to pay attention to the control of the lifting valve, because the output to the lifting valve has only one input signal, so it is only suitable for the use of single-coil reversing valve (two four-way valve) cylinder. Of course, double coil control can also be achieved through external relay extension, but single coil control can also achieve the control of lifting valve, we recommend the use of single coil control.

How to use pulse controller to control signal skillfully?

1. External differential pressure control switch

In the case of external differential pressure control switch, the output passive contact signal of differential pressure switch can be used as differential pressure control signal to realize the automatic opening of the pulse controller.

2. Use the panel installation type as the system start signal

The use of external panel switch to do the system start signal, the benefit is far more than the direct control pulse controller power supply, after customer verification, the MCU every power on all need 1 ~ 2 seconds of stability, and the use of this method, MCU is only in standby and work between the state of transition.

3. Install the control instrument on the top of the dust collector for remote control signal

Many small precipitators are installed directly on the top of the precipitator pulse controller, so through external control signals to control the opening and closing of the controller is very convenient
