Location of the pump’s optimal efficiency point
Thread Content
Dear all: According to API 610 6.1.13, the optimal efficiency point of a pump should be located between the rated flow rate point and the normal flow rate point. I have a few questions: 1. What is the difference between the rated flow rate point and the normal flow rate point, and how is it determined in practice? 2. Why must the optimal efficiency point be located between the two points? What will be the impact if the runtime efficiency point is outside these two points?
By understanding the working principle of the pump, these questions can be understood.
For example, an elevator is rated to carry 8 people (1000 kg); under normal circumstances, about 5 people will board it, with room for 1 more person. It’s not good either if too few people are carried or too many. Carrying one person wastes energy, while carrying too many leads to overload and prevents it from functioning properly
