| Abstract: | The leakage of powder might occur on the sealing spot after a period of time on account of the un reasonable design of sealing structure of driven shaft of TH250 powder lifter, which is unfavourable for the production. The overall structure of TH250 and the way to determine the driving power of troduced. Meanwhile a new type of seal structure is designed through technical reform the structure effectively solves the seal problem of driven shaft the motor of The practice rifter are inshows that |
