ZGB Series 5 Vanes Closed High Chromium Wear-Resistant Coal Mine
Slurry Pump
Main introduction:
The ZGB type slurry pump is a horizontal, single stage, single
suction, cantilever centrifugal slurry pump. The pump has the
characteristics of reasonable structure, high efficiency, reliable
operation and convenient maintenance and repair. It can be widely
used in electric power, metallurgy, mining, coal, building
materials, chemical and other industrial sectors to transport
slurry containing corrosive solid particles.
Multiple stages can be used in series within the allowable working
pressure range. The pump allows a maximum working pressure of no
more than 3.6Mpa

Structural features:
The ZGB slurry pump has the same structure except for the pump head
part (including the front and rear pump casings, the volute casing,
the front and rear guard plates, the impeller, etc.), and the rest
of the structure is similar. The same series of transmission parts
are used, and the pump head part and the shaft seal part are
pressed below. And the transmission part, respectively, describes
its structural characteristics.
1, ZGB slurry pump shaft seal part: shaft seal has three forms, the
auxiliary impeller shaft seal and packing shaft seal, mechanical
seal.
(1) Mechanical seal: For the condition that is not suitable for the
above two shaft seals, mechanical seal is adopted to reduce the
number of maintenance of the shaft seal part.
(2) Packing shaft seal: The packing shaft seal structure is simple,
the maintenance is convenient, and the shaft seal water is needed.
For the working condition which is not suitable for the shaft seal
of the auxiliary impeller and the working condition for pumping,
the packing shaft seal can be used.
(3) Sub-impeller shaft seal: Single-stage pump or multi-stage
series third-stage pump when the positive pressure of the pump
inlet is not more than 10% of the pump outlet pressure value, the
auxiliary impeller shaft seal can be used, and the auxiliary
impeller shaft seal has no Dilute the slurry, the sealing effect is
good and so on.
2, ZGB slurry pump pump head part: ZGB series slurry pump is a
double pump shell structure, namely the front pump casing, the rear
pump casing and the replaceable over-current part (including
impeller, volute, front guard, Rearguard). The front and rear pump
casings are made of gray cast iron or ductile iron according to the
working pressure. They are vertically opened and bolted. The rear
pump casing has a stop and bolts connected to the bracket. The
discharge port of the slurry pump can be installed at eight angles.
The front and rear covers of the impeller are equipped with back
blades to reduce leakage and improve pump life and efficiency. The
inlets of all types of pumps are horizontal, and the pump rotates
clockwise as seen from the transmission direction.
3. Transmission part: ZGB slurry pump adopts the same series of
transmissions, including bracket and bearing assembly. The pump
shaft has large diameter, good rigidity, short cantilever, and will
not bend and vibrate under severe working conditions. The bearing
adopts single row cone. Roller bearing and deep groove ball bearing
can be combined to withstand the maximum axial and radial load of
the pump. The bearing is lubricated with thin oil. The end of the
bearing body has a sealed end cap, which can effectively prevent
the slurry and other dirt from entering the bearing. ZGB slag The
slurry pump is provided with two hose joints in the bearing body,
which can be connected with the water source to cool the bearing
chamber, so it can work under high ambient temperature to ensure
the safe operation of the bearing and has a high life.
