6 Inch Diesel Engine Driven Centrifugal Pump Heavy Duty slurry pump
With Closed Type Impeller
Overview
The 6 Inch Diesel Engine Driven Centrifugal Pumps are cantilever
centrifugal slurry pumps, which are suitable for conveying abrasive
or corrosive slurry. They are widely used in metallurgical, mining,
petroleum, chemical, coal, power, transportation, River dredging,
building materials and municipal Engineering departments.
The series slurry pump can also be called heavy duty slurry pump.
Because the pump has thick bearing parts and heavy brackets, it is
suitable for conveying strong abrasion, high concentration slurry
or low concentration and high lift slurry. It can be used in series
At the maximum allowable working pressure range of the pump.
The 6 Inch Diesel Engine Driven Centrifugal Pumps are horizontal,
vertical open, double pump shell structure. The pump body and pump
cover have replaceable metal lining or rubber lining. The lining
can be used last worn out. It does not need to be replaced,
Prolongs the maintenance cycle and reduces the operation cost.
The 6 Inch Diesel Engine Driven Centrifugal Pump Heavy Duty slurry
pump uses a closed impeller. The closed impeller consists of blades
and front and rear covers. Closed impellers are more efficient.
In addition to the direct-coupled drive (DC), the 8/6E- slurry pump
has V-type V-belt drive, gear reducer drive, fluid coupling drive,
variable frequency drive, and thyristor speed control.

Precautions
During the operation of the slurry pump, attention should be paid
to the temperature and leakage of the packing gland. Normal packing
leakage should not exceed 10-20 drops per minute.
In the pump operation, if the slurry pump can take in air and it
can be solid, it will make an abnormal sound and vibrate
accordingly.
In the pump operation, if the backup valve of the backup machine
leaks and the switching valve is always open, it should be noted
that the backup machine is reversed due to the reverse flow.
When the pump regulates the flow during normal operation, it is not
possible to reduce the flow rate by reducing the opening of the
pump suction line valve. Otherwise, the pump inlet flow will be
insufficient and the pump will cavitation.
In the pump operation, for the bearings that need cooling water,
pay attention to the temperature and quantity of water, and try to
keep the bearing temperature within the specified range.
Slurry pump impeller function
1. The impeller is the part of the slurry pump overcurrent
component that works on the slurry.
2. The impeller is rotated by the pump shaft in the pump body to
obtain energy for the slurry.
3. The mechanical energy is transmitted to the slurry by the
rotation of the impeller, so that the slurry obtains the dynamic
pressure energy: it consists of four parts: the front wheel plate,
the rear wheel plate, the blade and the wheel hub.
