Horizontal Ring Section Self-Balancing Multistage Centrifugal
Mining Water Pump MD280-95X8P
Description
Water is a constant threat to mining, whether it enters a mine
through infiltration or comes from a storm. Mine operators must be
able to manage the water where it is known to exist and quickly
alleviate the problems associated with it when it rises
unexpectedly. Mine dewatering pumps generally need to pump water
horizontally-from a smaller sump to a larger sump-or vertically
from the bottom of the pit up to the elevation of the mine, and
then horizontally to a discharge point. The pumps most commonly
found in mine operations include vertical turbine pumps, electric
and hydraulic submersible pumps, horizontal multistage centrifugal
pumps and horizontal single-stage centrifugal pumps.
Our MD series self-balancing multistage ring section centrifugal
mining water pump is a innovative product which designed to remove
the mechanical balance drum, balance disc, balance socket and
related parts, and achieve the balancing function by reverse
circulation water pipe.
The external bypass pipe at the outside of the pump is
designed for water re-flushing, it will make the water flowing
directly into the end of the pump from the suction side, and
then return to the discharge section at the middle of the
pump, the axial force will be balanced by water flowing from
both sides of the discharge section.
It will balance the axial thrust caused by the high pressure
impeller from both sides and escape the mechanical wears out as
well as overloaded axial force of the traditional multistage pump,
and ensure the stability and endurability of the pumpset.
Horizontal centrifugal pumps can be multistage, i.e., multiple
impellers on a common shaft enclosed in the same pump casing. These
pumps generate increased pressure as the discharge of one enclosed
impeller is routed to the suction of another enclosed impeller
within the casing. Enclosed impellers limit the solids handling
sizes of these pumps. In addition, and much like their vertical
turbine counterparts, the efficiency and effectiveness of
horizontal multistage pumps is dictated by the life of the wear
rings and thin, multi-vane impellers.
