When using slurry pump, we all hope to improve the production efficiency
But in the actual production, there are always some factors to reduce the efficiency of slurry pump
So what are these factors?
Let's analyze these factors:
Factors to reduce the efficiency of slurry pump:
1. The efficiency of slurry pump itself is the most fundamental influence, and the pump efficiency under the same working conditions may differ by more than 15%.
2. The operation condition of the slurry pump is lower than the rated condition of the pump, with low pump efficiency and high energy consumption.
3. The efficiency of the motor is basically unchanged in use, so it is important to select a high efficiency motor to turn it off.
4. Hydraulic loss includes hydraulic friction and local resistance loss.
After the pump runs for a certain period of time, it inevitably causes the surface wear of impeller and other components
The hydraulic loss increases and the hydraulic efficiency decreases.
5. The influence of mechanical efficiency is mainly related to design and manufacturing quality. After the pump is selected, the later management has little influence.
6. Pump volume loss is also called leakage loss
Including three leakage losses of impeller seal ring, interstage and axial force balance mechanism
Volume efficiency is not only related to design and manufacturing, but also to later management
After continuous operation of the pump for a certain period of time, due to the friction between the components, the clearance increases and the volumetric efficiency decreases
7. Because the filter cylinder is blocked and the pipeline is aspirated, the slurry pump is vacuumed and idled.
8. Before the start of slurry pump, employees do not pay attention to the preparation before the start of centrifugal pump
The basic operating procedures of warm-up pump, disk pump and filling pump were not thoroughly implemented
Often causes the pump cavitation phenomenon, causes the pump noise big, the vibration big, the pump efficiency low.
The above eight factors can not be ignored to reduce the efficiency of slurry pump.
To make the slurry pump work better, pay attention to the maintenance of slurry pump.
