The invention provides a lifting component for a high-purity ammonia storage cylinder, and belongs to the technical field of machinery. By adopting the lifting component for the high-purity ammonia storage cylinder, the problem in the prior art that stability is poor is solved. The lifting component for the high-purity ammonia storage cylinder comprises a motor, a screw rod, a lifting barrel and aguiding structure; a base comprises a block-shaped body I and a block-shaped body II; the motor is fixedly connected to the body II; a rotary shaft of the motor is fixedly connected to the lower endof the screw rod; the lifting barrel is axially and fixedly connected to the body I; the upper end of the screw rod is embedded in the lifting barrel and is connected to the lifting barrel through threads; and a contact structure which can reduce friction resistance between a connection barrel and the body I is arranged between the end part of the connection barrel and the body I. The lifting component for the high-purity ammonia storage cylinder is high in stability.
