当总循环泵变速运行时，各个支路的流量分配比例保持不变。
When the total cycle pump gear shift operation, the flow of the slip road ratio unchanged.
管段流量与终点水温的关系，是热水供应系统中循环泵选择计算研究的一个重要理论依据。
Therefore, this conclusion should be taken into account when we study how to select one circulation pump with reason in a hot-water supply system.
由于发动机冷却水循环泵由发动机带动，因此冷却水的流量仅同转速有关。
As the engine cooling water pump driven by the engine, so only the flow of cooling water of the same speed.
