Beschreibung
Zusammenfassung:	The invention belongs to the technical field of fluid machinery, in particular to a follow-up motor type mechanical on-service adjusting device for the blade angle of a water pump. The follow-up motor type mechanical on-service adjusting device for the blade angle of the water pump comprises an adjusting motor, a speed reducing mechanism, an adjusting nut, an adjusting threaded rod and the like. The adjusting motor drives the speed reducing mechanism to operate so that the adjusting nut can be driven to rotate, and finally the adjusting threaded rod is driven to generate axial movement capable of changing the blade angle of the water pump. The follow-up motor type mechanical on-service adjusting device for the blade angle of the water pump is characterized in that an adjusting motor body can operate along with an adjusting device body, in addition, a lubricating and sealing system for the adjusting nut and the adjusting threaded rod is arranged, by the adoption of the structural layout of the sealing sleeve o
