>>> Product Overview XBD series fire pump is the third
generation of our company based on the performance parameter of
international standard ISO2858 and JB/T6878.2-93, and "performance
requirement and experimental method of fire pump" of GB6245-2006
issued newly by nation. It is an upgrated product of old type XBD
with flow range of 1.5 to 1600m3/h and head range of 5 to 225m.
>>> Product Applications: XBD series fire pumps are
mainly used in the hydrant and automatic spray extinguishing
systems etc. in the fixed fire fighting system in
enterprises,institutions,project construction,high building etc,to
deliver clean water and medium similar to water in physiochemical
property,not containing solid grain and of temperature below
40°C. >>> Product Working Conditions 1. Please
inform us when placing an order if the working pressure of the pump
system is larger than 2.5MPa. 2. Proper medium: liquids with
chemical property similar to pure water should be non corrosive.
Solid size should be no larger than 30% of the pump suction
diameter. Fiber length should not be over 2.5 times of the pump
suction diameter. When the medium density is more than 1.05, the
motor power should be increased accordingly to prevent the motor
from overload operation. 3. Surrounding ambient temperature should
not exceed 40°C. Altituide should not exceed 1000m, Transferring
medium temperature should not exceed 40°C. Please inform us when
placing an order if the transferring medium
temperature exceeds 40°C. The motor power should be increased
in order to adapt to the high altitude area if the altitude exceeds
1000m. >>>Product Features 1. High efficiency and energy
saving Adopt CFD(computational fluid dynamics) to analyze and
calculate the relationship between pump pressure distribution and
valocity distribution. Optimize the pump flow channel design to
ensure a highly efficient hydraulic line and highly improved
efficiency. 2. Comfortable installment and maintaining The new
upgrated fire electric pump units combine using and maintaining.
Stainless steel impeller and pump spindle could prevent the entire
rust situation with pump body, which integrates domant stablility
commonly and starting reliability casually. 3. Stable operating
with safety and reliability Techniques with positioning connection
form makes sure that pump and motor has stable operating more safe
and reliable with coaxiality concentricity. 4. Bearing Both float
shaft bearing for motor shaft below (YX3) 280 and fan end shaft
bearing for motor shaft below YX3-180 adopt the sealed shaft
bearing. Under normal condition, motor shaft bearing is free of
maintenance. 5. Mechanical seal Basic part of the machanical seal
generally asopts the rubber corrugated pipe structure to replace
the O-ring line seal with rubber dual face seal as the shaft seal,
which improves the sealing effect when the medium is clean water.

Vertical Multistage Fire Pump>>> Installation Instructions
1. Check whether pump fasteners are loosen and whether the pump
body runner is blocked by foreign matters before installation to
avoid damage of impeller and pump body in running. 2. The
independent supporting shall be installed when installing inlet and
outlet tube of pump, so as to remove the pressure of the inlet and
outlet tube from pump and keep the shape of pump. Meanwhile, a
series self-regulation compensators such as flexible joint shall be
installed so as to adjust error of installation and avoid pull
caused by different thermal ratios of requirement and tube in
different seasons. The butterfly valve and sluice valve are
installed at lnlet and outlet parts of water pump for maintenance
using. The outlet part shall install back-pressure valve so as to
ensure that the net pressure would not backblash in the pump. 3.
XBD-KYL, XBD-DL, XBD-GDL, XBD-LG, XBD-HY series vertical fire pump
must be through gradienter. After the solidification of foundation
cement, pump is installed on the foundation, the upright situation
of pump and motor shaft should be detected. Iron pad adjust the non
upright situation. Then cement through grout hole pours foundation
and anchoring hole. 4. XBD-KYW, XBD-HYW series horizontal fire pump
must be through gradienter, after the solidification of foundation
cement, pump is installed on the foundation, and horizontal
situation of pump and motor shaft should be detected by gradienter.
Iron pad adjust the non horizontal situation. Then cement through
grout hole foundation and anchoring hole. 5. For the sake of
convenient service and safe use, mount one regulation valve on both
inlet and outlet pipelines of the pump and one monometer near the
out
