1) Primary dynamic pressure
一次动压
2) primary air pressure
一次风压
1.
As a result,the opening of inlet damper is so small that the primary air pressure is too high and some pressure energy depletes during throttling with too much power consumption in pulverizing system.
在中速磨煤机制粉系统运行中,普遍存在着靠磨煤机入口风量挡板调整磨煤机通风量的大小,使磨煤机入口风量挡板开度很小,造成一次风压过高,一次风机的部分压能损失在挡板节流上,浪费了制粉电耗,这是中速磨煤机制粉系统运行中的一个误区。
3) the primary oil pressure
一次油压
1.
An analysis of the influence of oil temperature and oil gap leakage on the primary oil pressure has been given.
通过对 6号汽轮发电机组负荷异常降低到零的故障分析 ,计算、比较了油温及间隙漏油对一次油压的影响 ,总结提出了维持一次油压正常的几点建
4) primary voltage
一次电压
5) PRGMR. Primary
一次,低压
6) single pressing
一次压榨
