Abstract

A method for controlling the operation of a dust remover, the method comprising: obtaining sensor data (235) relating to an airflow (240) entering the dust remover (step S1); determining, based on the sensor data (235), whether the dust remover is operating in a high airflow operating range (step S2); and controlling a fan motor (210) of the dust remover to reduce the air flow (240) to a reduced flow level (330, 330 1) at or above a predetermined air flow level (340) and below an available flow level (310) in case the dust remover is operated in the high air flow operating range (step S3), where the predetermined air flow level (340) is associated with the dust collection capability of the dust remover (100).

Description

technical field [0001] The present disclosure relates to heavy duty vacuuming devices for use with construction equipment. A method and a control unit for controlling a fan motor included in a dust collector are disclosed. Background technique [0002] Dust and slurries are generated by cutting, drilling, grinding and / or removing concrete, brick and other hard construction materials. Dust and slurry can be collected by dust collectors and removed from construction sites in a controlled manner. A dust collector is a vacuum device that collects dust and slurry by generating negative pressure by a fan or impeller and motor equipment, that is, similar to a vacuum cleaner. Some dust collectors include a pre-filter or separator followed by a filter, such as a high-efficiency particulate air (HEPA) filter. [0003] Dust collectors typically include an electric motor powered by a mains and are therefore limited by the capacity of the power supply. It is desirable to minimize ene...
