18/16TU-G Sugar Plant Electric Centrifugal Pump / Tailing Transport
Slurry Pump
Description
- The traditional concept of water pump design is that hydraulic
design is higher than structural design, in order to improve the
efficiency of water pump by 1%, regardless of the cost of products
increased by 10%. In the traditional design concept, design and
structure of hydraulic blade oblique flow impeller with space
become the main design method of deep well pump, because of the
high efficiency of the pump of this type, flow and head is also
consistent with the national standard value. However, this kind of
deep well centrifugal pump has the largest axial size, the most
difficult to manufacture blades, the highest production costs, so
its comprehensive economic benefits are very low.
- If the change of design concept, the design of the structure is
placed in front of the hydraulic design, according to the hydraulic
design method to determine the structural conditions, to reduce
production costs and improve reliability in the first place, to
meet the needs of hydraulic design, structure design, for deep well
pump, requires the use of vertical structure, which is a kind of
impeller maximum diameter design method and structure form of anti
missile vane supporting shell, this structure can achieve the
maximum diameter of the impeller, the shortest length of diversion
shell structure requirements.
- In this form of structure, the method of hydraulic design can be
expected to achieve maximum economic benefits.
Centrifugal pump (slurry pump) operation should pay attention to
the following points:
- Prohibition of waterless operation, do not adjust the suction
population to reduce displacement, prohibited under low flow
operation;
- Monitor the operation process, completely prevent the packing box
from leaking and replace the stuffing box with new packing;
- Ensure that the mechanical seal is adequately flushed and water
cooled bearings prohibit the use of excessive water flow;
- Don't use too much lubricant;
- Check according to the recommended cycle. Set up operation records
including running hours, filling adjustment and replacement, adding
lubricant and other maintenance measures and time. The centrifugal
pump suction and discharge pressure, flow rate, transmission power,
the temperature of the wash and bearing, and vibration should be
recorded regularly.
