Abstract:Aimed at the high oil temperature problem of the tamper molding machine for cigarette dust extraction in summer,in order to prevent the lubricating failure,a circulating pump was increased to decrease the cooling water temperature and at last reducing oil temperature.By using temperature control methods to start and stop the circulating pump,a good temperature control effect is realized.The oil temperature of the tamper molding machine is reduced from 65 ℃ to 55 ℃ in summer After the improvement,and the operation reliability of the drive friction pair is improved.
