The three control modes of the pulse controller indicate that the three control modes of the convenient pulse controller are convenient. The electromagnetic pulse valve of the convenient pulse controller is effective for circulating cleaning of the filter bag, which is controlled by its output signal. Ensure the treatment capacity and dust collection efficiency of the dust collector. Mainly used in kiln, cement shaft kiln, mining and other industries pulse control instrument is the main control device for pulse bag type dust collector spraying and cleaning. The pulse interval, pulse width, number of output channels, and cycle interval of the pulse controller are adjustable, and the data can be displayed by a digital tube, and the number of output channels can be adjusted according to requirements. Most of the parts of the product are imported parts, and the performance is higher than that of similar products on the market, which makes the operation more intuitive and simple, and the performance is more stable.
The pulse signal generator is the main control device of the pulse bag type dust collector. By adjusting the pulse period and pulse width of the control instrument to ensure the normal operation of the dust collector, its performance directly affects the cleaning effect. The pulse controller has Electric control, pneumatic control and mechanical control.
1) Mechanical pulse controller: Using a mechanical transmission device, the pulse valve is directly triggered one by one. The characteristics are easy to master, reliable in operation, small in random variation, easy to realize system output, simple in structure, low in cost, convenient in maintenance, long in service life, easy to adjust pulse width, and not affecting temperature. The disadvantage is that the pulse period is fixed and cannot be adjusted.
2) Electric pulse controller: The electric pulse controller uses 220V power as energy source to output electric pulse signal, and it is used with solenoid valve, pulse valve or electromagnetic pulse valve. For example, the WMK type non-contact pulse controller is composed of a transistor circuit, which is characterized in that the pulse width and the pulse period can be adjusted at will, the adaptability is good, the use is reliable, the adjustment is easy, and the remote control can be performed. The disadvantage is that the structure is more complicated, requires a high level of maintenance and management, and is greatly affected by the environment. The general ambient temperature is -20~55 °C, and the relative temperature is 85%.
3) Pneumatic pulse control instrument: Pneumatic pulse control instrument uses clean compressed air to generate energy and output pneumatic pulse signal. It is equipped with pneumatic valve and pulse valve. The pneumatic pulse control instrument is composed of pneumatic pulse combination instrument. The characteristic is that the pulse width and the pulse period can be adjusted at will, and the automatic control can be realized, and the pneumatic control is also relatively easy. The disadvantage is that the cycle and width will change after using a section, it is not easy to adjust, and the maintenance workload is large: the environment is required to be clean, the working temperature is between -5 and 50 °C; compressed air is required.
