  Brief introduction of structure:

    1. DY type is horizontal, single-shell, radially split multistage centrifugal pump, inlet, outlet flanges are vertical upward, horizontal center line

         Support: DYP pump suction inlet is horizontal, horizontal outlet can also be vertical, foot support.

     2 impeller, balancing drums, bushings, etc. in turn mounted on the shaft, rotor components made by the both ends of the bearing radial and axial spacing.

     3 by the double-balanced drum axial force balance, the residual axial force from the thrust bearing to withstand.

     4 with the wear bar to inhale, middle, spit connected into one segment.

     5 bearings sliding bearings, thrust bearings angular contact ball bearings or thrust bearings Mitchell.

     6 using self-lubricating bearing lubrication (oil ring) or forced lubrication.

     7 static metal sealing surface sealing, wound pad seals and "O" ring seal.

     8 dynamic seal for mechanical seal, wash rinse cycle way from, outside tap and rinse washing three ways.
