D (DF, DY)and DG are horizontal, single-suction and multi-stage
centrifugal pumps. Their suction inlets are in a horizontal
direction while their discharge outlets are upward and vertical to
the horizontal line. Their case part, including water inlet
section, middle section, water discharge section and bearing body,
are integrated through the tension bolts. The pump stage number can
be selected in accordance with its lift head. (The water pump's
inlet and outlet directions can be customized).
The rotor part of this series is mainly made up of the shaft and
such parts mounted on the shaft as impeller, bushing and balanced
is c. Of them, the impeller quantity is subject to the pump stage
number. The parts mounted on the shaft are fastened with flat keys
and spindle nuts to make them integrated with the shaft. The whole
rotor is supported by rolling or sliding bearings on both ends. The
bearings, subject to different types, all bear no axial force.
Instead, the axial force is balanced by the balance disc. When the
pump is running, the rotor is allowed to move an axial movement in
the pump case. The annular ball bearing is not allowed to be used.
The rolling bearing shall be lubricated by grease while the sliding
bearing by thin oil with the oil ring for self-lubrication and the
circulating water for cooling.
The sealing surfaces between the pump's water inlet section, middle
section and water outlet section all adopt the molybdenum
disulphide grease for sealing. There's a sealing ring, a guide vane
bushing and so on mounted between the rotor and fixed parts for
sealing. When the sealing ring and the guide vane busing are so
worn to have an impact on the pump's working performance, they
shall be replaced.
The shaft seal has two modes: mechanical and packing. D pump adopts
the packing seal mostly while DF and DY pumps adopt mechanical seal
generally. Incase of packing seal, the packing rings hall be
positioned accurately with a proper tightness of packing, subject
to such a standard that the liquid can seep drop by drop. All
sealing elements of the pump are mounted in the sealing chamber
with a certain pressure of water inside the chamber for the purpose
of water seal, cooling or lubrication. There is a removable bushing
mounted on the shaft seal to protect the pump shaft.
DG pump sub-high pressure pump adopts the structure of sliding
bearing with thin oil lubrication generally. DG85-67 and DG 155-67
pumps adopt the structure of either sliding bearing with thin oil
lubrication or rolling bearing with grease lubrication. The rest
types all adopts the structure of rolling bearing with grease
lubrication. Generally the major part so flow/middle pressure pumps
adopt high-quality cast iron while those of sub-high pressure pumps
adopt cast or stainless steel.
This series is directly driven by the prime motor through the
elastic coupling. When viewed from the prime motor direction, the
pump rotates clockwise.
