Air intake filtration systems for vehicles operated in high-dust conditions are characterized. The purposefulness of ongoing removal of dust trapped by cyclones from the sediment tank is explained. An ejection system for dust extraction from an inertial dust collector sediment tank is characterized. The influence of the extraction rate m on the efficiency and flow resistance characteristics of inertial dust collectors is presented. The reasons for the lower dust removal efficiency of a multicyclone compared to the individual cyclones from which it is built are analyzed. A methodology for experimental testing of the uniformity of dust extraction from individual cyclones of a multicyclone has been developed.Measurements of the values of extracted streams QSC from individual cyclones of an air filter multicyclone were carried out.
THE PROBLEMS OF DUST EXTRACTION FROM AIR FILTERS OF SPECIAL VEHICLE ENGINES
Inlet air filtration systems of vehicles exploited at large air dustiness conditions are characterized. The purposefulness of current sucking-off of the dust stopped by cyclones expediency is explained. An ejective system of dust extraction from a cyclonic deduster has been discussed. The influence of rate of extraction m on the characteristics of purification efficiency and flow drag of cyclonic dedusters has been presented. The authors have analyzed the reasons for lower efficiency of multicyclone extraction versus the extraction of an individual cyclone, from which a mutlicyclone is composed. There has been worked out a methodology of experimental research of dust extraction uniformity from individual cyclones of a multicyclone. The extracted streams QSC from individual cyclones of a multicyclone in the air cleaner have been measured. (…)
