General
Model S pump is a single-stage double-suction horizontal split
centrifugal pump and used to transport pure water and the liquid of
both physical and chemical nature similar to those of water, the
maximum temperature of which must not be over 80℃, suitable for
water supply and drainage in factories, mines, cities and electric
stations, waterlogged land drainage and irrigation of farming land
and carious hydraulic projects.
Structure
Both inlet and outlet of this pump are placed under the axial line,
horizoutally and vertical to the axial line, the pump casing is
opened in the middle so it is unneccessary to remove the water
inlet and outlet pipelines and motor. The pump moves CW viewing
from the clutch to it. The pump moving CCW can also be made, but it
should be specially noted at order.
The main parts of the pump are: pump casing(1), pump cove(2)r,
impeller(3), shaft(4), dual-suction seal ring(5), muff(6),
bearing(15), etc. and all of them, except the axle which is made of
quality carbo steel, are made of cast iron. The material maybe
replaced with others upon different media.
Both pump casing and cover form the working chamber of the impeller
and there are threaded holes for mounting vacuum and pressure
meters on the flanges ant both inlet and outlet and for water
draining on the lower side of them.
The impeller is static-balance calibrated, fixed with the muff and
the muff nuts in both sides and its axial position can be adjusted
via the nuts and axial force gets balanced by means of the
symmetrical arrangement of its blades, there may be residual axial
force which is borne by the bearing at the axle end.
The pump shaft is supported by two single-column centripetal ball
bearing, which are mounted inside of the bearing body on both ends
of the pump and lubricated with grease. The dualsuction seal ring
is used to reduce the leak at the impeller.
The pump is driven directly by means of connecting to it via an
clastic clutch.(set up a stand additionally in case of a rubber
band driving).
The shaft seal is packing sealand, to cooland lubricate the seal
cavity and prevent air from getting into the pump, there is a
packing ring between the packing. A smallvolume of high-pressure
water flows into the packing cavity via the tapered beard during
the pump’s working to act as a water seal.
