Application of Frequency Conversion Control of Dust Removal Fan in the Positive Pressure Purification System of Electric Shovel
Due to the harsh working environment,the traditional dust removal device of WK-35 often blocks or lacks ventilation,causing dust to invade the machine shed,resulting in high temperature of the components inside the electrical cabinet,seriously affecting its lifespan.This makes the electric shovel frequently require shutdown maintenance,greatly reducing the efficiency of the dust removal system.A new ventilation device for the electric shovel shed has been designed to address this situation.By increasing the ventilation volume,it meets the needs of ventilation,dust removal,and cooling in the shed,and requires the fan to have temperature control and adjustment functions.A variable frequency control method for the dust removal fan has been designed to meet the electrical requirements of the ventilation device.After renovation,the ventilation and cooling performance of the WK-35 shovel can meet the requirements of the entire shovel positive pressure purification system.
