Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of pulse controllers, and particularly relates to a pulse controller with strong sealing performance. Background Art
[0002] The pulse controller is the main control device for the pulse jet cleaning of pulse bag filters. Its output signal controls the electromagnetic pulse valve to perform cyclic cleaning of the filter bags to ensure the treatment capacity and dust collection efficiency of the dust collector. The pulse controller adopts a unique anti-interference technology, which can ensure stable and reliable operation in the harshest industrial environment and can completely replace the PLC control to achieve the cleaning control of large dust collectors.
[0003] Most pulse controllers adopt the combination of a rear shell and a transparent front shell. When the rear shell and the front shell are combined, gaps will be generated, resulting in dust and water easily entering the interior of the pulse controller through the gaps between the rear shell and the front shell, which is likely to affect the normal use of the pulse controller and reduce the service life of the pulse controller. Therefore, we propose a pulse controller with strong sealing performance. Content of the Utility Model
