the pulse controller is the main body of the injection dust cleaning control device of the pulse bag filter. the pulse controller keeps the operating resistance of the dust collector in a controllable range to ensure the processing capacity and dust removal efficiency of the dust collector. botou jingbo dust removal equipment co., ltd. is a large-scale enterprise specializing in the production of a variety of dust removal equipment and dust removal accessories. the company's main products include: electrostatic precipitator, star unloader, high-voltage electrostatic precipitator, rotary umbrella high-efficiency electrostatic precipitator, collective high-voltage electrostatic precipitator, dust collector, tubular electrostatic precipitator, wide spacing electrostatic precipitator, pulse bag type dust collector, long bag off-line pulse dust collector, high-voltage off-line pulse bag type dust collector, micro shock flat bag dust collector, rotary back blowing dust collector bag type back blowing dust remover, dust removal framework, single machine dust remover unit.
the duration of each driving voltage of the pulse controller is called pulse width. the interval between two adjacent output driving voltages is called pulse interval. the time required for the pulse controller to complete the solenoid valve drive output is called the pulse cycle. the pause time between two pulse cycles is called the cycle interval. according to the dust removal requirements of the dust remover, set the cycle interval, pulse interval and pulse width parameters of the pulse controller, control the opening and closing of the electromagnetic pulse valve, and carry out regular dust removal of the dust remover. the pulse controller is equipped with the input contact of the differential pressure controller. after the differential pressure controller is connected, the ash can be cleaned at a constant differential pressure.
the circuit board on the pulse controller has led to display the working sequence of the electromagnetic pulse valve in turn. the manual button on the printed circuit board can check the operation of the electromagnetic pulse valve in turn. if the hａnd in button is pressed and held, the automatic carry can be locked. the nixie tube on the circuit board can display the timing time during operation and the parameter value during parameter setting. the pulse controller adopts a fully sealed plastic shell with good dust-proof performance. there are knock-out holes around and at the bottom for wiring, which can adapt to wiring in all directions and is convenient for installation and use.
wmk-20 dust removal controller is suitable for automatic dust removal control of various bag filters. it is controlled by single chip microcomputer. the parameter storage period is more than 10 years. various parameters are accurately adjusted, key operation, digital display, high-power contactless output, reliable short-circuit protection function, digital display, single valve continuous multi pulse output preset, timing and constant pressure, it can be selected according to user requirements, and can also be customized for special requirements.
