进口高温高扬程泵Product Description:

With the impeller axial buffer device, the impeller hub is fixed on the pump shaft, the pump shaft is fixed with an axial extrusion part, the impeller hub and the axial extrusion part are connected with each other through an elastic part, and the elastic part applies a preload to the impeller hub in the direction parallel to the axis of the pump shaft. The impeller hub and the axial extrusion part are connected together through an elastic part, and the elastic part is compressed through the extrusion of the axial extrusion part, so as to apply a preload parallel to the axial direction of the pump shaft to the impeller hub, so as to prevent the impeller hub from axial displacement and irreversible damage.

进口高温高扬程泵characteristic:

The pump shaft is successively provided with a spring seat, a snap ring and a limit ring along the direction away from the impeller hub. The spring seat is an axial extrusion part, and the elastic part is a spring; The snap ring is fixed on the pump shaft, the limit ring body bulges towards the impeller hub to form a convex part for pushing the spring seat. The limit ring and the snap ring are connected by fixed bolts. By tightening the fixed bolts, the convex part on the limit ring pushes the spring seat to move towards the impeller hub, and the spring seat presses the spring to form a preload.

进口高温高扬程泵Principle:

The axial extrusion part and the elastic part are spring seat and spring respectively. The snap ring is fixed on the pump shaft, and the snap ring and the limit ring are fixed by fixing bolts. By tightening the fixing bolts, the convex part of the limit ring body exerts a pushing action on the spring seat, so as to compress the spring, so that the spring exerts a pre tightening force on the impeller hub; In order to prevent the fixed bolt from being too long to touch the spring seat, a holding cavity can be set on the spring seat for the fixed bolt to stretch into; Of course, when the limit ring body is not provided with a convex part, the fixed bolt is used to buttress the spring seat, and the end of the fixed bolt can directly push the limit ring to move.
