Then it has potential structural stability problem. Since the top of the guide rod and the screw post is in a suspended state, the necessary support structure is lacked, and the lifting seat mainly relies on the driving force of the single side of the screw post in the lifting process. The lifting mode of the single side stress is easy to cause the deformation of the lifting seat under the uneven stress, and then affects the normal operation and service life of the whole fire hydrant system.
