BQS(BQW) Flameproof submersible centrifugal sludge
pump
Summary
Comprehensive optimized and innovative designed
in the aspects of hydraulic model, sealing technology, mechanical
structure and protection control. Compared with domestic products,
this product has the advantages of safe&reliable,
portable&practical, good sewage flushing performance, long
serving life and so on. The whole series products are featured for
reasonable spectrum and convenient lectotype.
Â
Model screening: optimized performance, double
channel impeller, stable operation without clogging, strong sewage
flushing ability. Pump has the property of no overload(full head),
which means the power will never surpass the matched motor
power in any working condition. It applies to any coal mine
occasions, also can be multiple used.
Â
Mechanical seal reforming: adopts independent
serial mechanical seal and double-end mechanical
seal.
Â
Structural optimization: structure design is
good for mechanical sealing, smooth operation, higher reliability;
optimal design, more portable and practical, low energy
consumption. Long-time running in anhydrous
state.
Â
IPX8 motor protection class, good submersible
motor cooling effect, lower temperature rise than ordinary motor,
further improved durability, F class insulation to improve motor
serving life.
Â
Application:
Suitable for coal mine places contains
methane(commonly known as gas) and coal dust with explosion danger,
transportation for the mixed sewage contains the insoluble solids
centents like silt, slurry, gangue, cinder, and fiber. Which can
also be used for construcntion of building and bridge, sewage
discharge for hospital, resident area, public engineering, and road
traffic, transportation for sewage contains solid particles, waste
water with long fiber, and rainwater in small sewage
treatment.
Â
Working
condition:
Â
1.
Power: **0V or **0V, ***0V three-phase, *0HZ.
2. Medium temperature:
usually≦**0C, PH:**9, medium
density≤*1N/m3
3, Make the center of impeller as base,
underwater depth no more than 3m.
4. Unsuitable for strong corrosivity
fluid.
5,Diameter of solid in the medium should meet
the standard of MT/T*******5.
6,MT**8.*****9 coal mine used fire-residant
cable.
Â
Characteristic
1,Pump impeller
On the basis of testing, carefully choose and
match the pump body and impeller to realize non-clogging, high
efficiency, flat power curve, and non-overloading. The impeller is
balance and precise, with small vibration and running
stable.
2,Motor
Specially designed submersible motor, IPx8
protection, F grade insulation allows high temperatrue rise. In
normal temperature rise condition, the motor insulation life
prolonged. While, the diving makes coolling effect good, the actual
temperature rise low, thus the motor insulation life is much
longer.
3, Motor cooling
The motor dispatches heat through shell, if
only the medium submerged half of the sub-shell, the motor can run
stablly and safely. The more the sub-shell is submerged, the better
for motor cooling. The mechanical seal is series type. There is a
new type of double-end mechanical seal and pump adopts sandwich
strong cooling structure, which is our
companys
patent. At the first mechanical seal, make the medium decompression
to cool the motor, thus the motor can be idle running and always
keep the motor temperature rise below *0℃,greatly improves the
machines
serivice life. Suitable for the shallow water occasion, the pump
can be idle running for a long time without water. Can be used in
an unattended environment, save the labor
cost.Â
Â
4,Shaft seal
The shaft seal of motor adopts two independent
series mechanical seal to form 2 reliable sealing line. The first
sealing line is in the pump medium, the sealing surface will be
more tight with the increasing of medium pressure, which
effectively prevent water entering the oil chamber. The send
sealing line lies in the oil chamber to prevent oil entering the
motor. If the first line failed(its working condition is worse than
the second), the second line still can prevent water and oil
entering the motor. Bellow type mechanical seal matched with
innovative structure cavity, which greatly improve the reliability
of the shaft seal. Under the normal working condition, it will work
without failure for more than ***0h.
5.The oil chamber
The oil chamber is a barrier to prevent the
medium entering the motor. If the first mechanical seal leaked, the
oil chamber will buffer and prevent medium entering the motor.
Lubricating and coolling the 2 independent mechanical
sealsfriction surface at the same time to make the
mechanical seal work more stable. Besides, it can also takes away
some heat of the lower bearing and motor.
6, Bearing
The lower part of the double row angular
touches the bearing to generate strong carrying capacity, forms the
reliable support for the motor pump shaft with the upper deep
groove bearing, produces radial force, axial force and other forces
to pump during working. Have larger load margin to ensure the unit
work stable and serve a long time.
7,Cable and its
seal
(1.)Adopts MT**8.*****9 coal mine used
fire-residant cable, cable core section designed according to the
condition of *0℃environmental temperature and the motor works
stable and long-term with full load power. During working, if the
motor is not full load power and the environmental temperature is
below *0℃,
its serve life will be longer.
Â
(2)There is seal between the cable rubber
sleeve and motor cover to press tight, which prevent the medium
infiltrating the motor through the interface of cable and motor
cover.
Â
8 The motor casting, upper cover, lower
cover and other parts make up the motor shell. All the connection
of the parts have reliable static seal. Each has been checked
strictly by water pressure test to ensure there is no leakage and
perfectly safe.
Â
9, Special handle
Set special handle for easy moving. Absolutely
forbidden pulling cable(or use as string) when moving, thus the
seal between cable and motor cover will be loose and results in
water enter the motor. Even after pressed and fixed the cable onto
the handle, pulling the cable to move the sewage and sand
submersible pump is also forbidden.
Â
â–  Pump
selection
According to the
required flow Q(m3/h) and head (m) to search the model which the
matched or similar data correspond in the basic paramete table.
Flow should be within *2% to 5% of the needed, pump head should
better be higher than needed by 2% to 3%.
 How to choose the pump? Brief discription
stated as below to make some help.
Â
The flow marked on the nameplate and in the
parameter table are calledrated flow,
the head corresponds to the rated flow israted head(general the pump has the highest efficiency at
this condition). Suppose the rotating speed of motor is the same,
usually, for the same pump, its corresponding head will reduce with
the increase of flow, while, the motors
/output power will increase with the increase of flow. If the
flow increased to 1.2 times of the rated flow, the motor may run
overload, thus the motor will burn easily.
Â
Flow shows the amount of liquid or output
by motor in unit time. Pump head is the energy added value for unit
weight liquid goes from pump inlet to pump outlet. (Simply, under
the condition of no energy consumption, the unit weight liquid goes
through the pump, from the liquid surface the pump stays in to the
highest vertical height can be sent, namely is pumping liquid
column height, we used to call it meter for
short.
Â
When choosing the pump head, we must know: 1.
Net head**-the vertical height(m) between the the liquid surface
pump stays in to the surface the liquid should be pumped to. 2.
Needed head=Hnet+Hloss 3. Hloss**-The energy loss of the
liquid when goes through the pipe, valve, elbow and such
component.
