Machine PumpCirculation system-relay pump stationThe relay pump
station is divided into feeding slurry pump stations and
discharging slurry pump stations. The pump station is usually
equipped with an Feeding (discharging) slurry pump, motor,
transformer, the frequency converter, control cabinet and sealed
flushing booster pump group, etc., It is connected to the main
control room of the shield machine through the substation control
system for remote control.Feeding Slurry Pump station:The conveying
medium is a kind of prepared muddy water, which is mainly composed
of bentonite, CMS (methyl-condensed starch), sodium carbonate and
water. The specific composition should be related to the stratum,
and the fluid is within the range of 1.05-1.2. Compared with the
discharge slurry pump, the slurry inlet pump is lighter in weight,
small in size, and easy to install due to its density and low
wear.Discharge Slurry pumping station:The conveying medium is
slurry, which is mainly a mixture of soil slag that has been cut
and muddy water. Generally, the density is in the range of
1.15-1.4.Slurry Pump for Slurry Separation SystemThe slurry
separation station is for processing the slurry generated by the
tunneling of the shield machine during the construction of the
subway shield. The design and matching of the separation station is
mainly determined according to the pump flow rate of the shield
machine. Since the separation station is a modular design, it can
be installed according to the different flow rates produced by each
project.The slurry pump is a vital part of the slurry separation
station, and the stable operation of the slurry pump is directly
related to the operation status of the entire separation
station. Our company's slurry pump plays an important role in the
separation stations at different shield tunneling sites, and proven
to be of good performance.With the development and need of
shield-driven tunnels in domestic and foreign infrastructure
constructions, the buried depth is greater and the water pressure
is higher. A large-diameter shields machine is used to construct
the tunnels which are under various complex geological conditions.
According to the characteristics of the slurry pump and the complex
geological structure, our company specially designed the slurry
pump to continuously lead the technological progress and
development of tunnel construction. Qiangda Pumps adopt
better pump front liner, impeller and pump body material which are
strength optimization structure design to improve toughness
wear resistance and impact resistance, thus could deal with
different complex and harsh working conditions. At the same time,
our company's 300KSGH high-head slurry pump has been designed and
tested in this field and got very good feedback. The flow rate is
2800-3500m3/h, the speed is 550-700/min, the head is 60-80m, and
the efficiency is 78. this kind of pump could be used for
supporting large-scale shield machines over 12 meters.Feathered
