充水水泵在启动以前,泵壳和吸水管内必须先充满水,这是因为有空气存在的情况下,泵吸人口真空无法形成和保持。暖泵输送高温液体的泵,如电厂的锅炉给水泵,在启动前必须先暖泵。这是因为给水泵在启动时,高温给水流过泵内,使泵体温度从常温很快升高到1~2℃,这会引起泵内外和各部件之间的温差,若没有足够长的传热时间和适当控制温升的措施,会使泵各处膨胀不均,造成泵体各部分变形、磨损、振动和轴承抱轴事故。
ADL系列导轨式安装电能表不仅在外形和接线上具有灵活方便的特点,而且在功能和性能上也具有下述优点:a.计量正反向有功电量,功率潮流方向自动识别并指示,具有4费率及总电能计量功能。分时复费率功能,日时段可设4费率、8时段,时段内的小时间单位为1min。按月冻结转存功能,可统计上上月、上月及本月的总用电量和分时电量,用于月用电费的结算及监测用电情况。实时监测功能,测量显示电压、电流、频率、功率、功率因数。
下面举几个案例:贵州省某电厂,由于意外原因造成汽轮机突然停机,和汽轮机同轴高速运转的发电机不可能因此在短时间内降低转速,这时必须启动直流泵(或直流电机)来带动汽轮机继续转动,避免汽轮机和发电机之间的同轴扭曲,造成设备报废。然而在该电厂就是蓄电池没有足够的电能来带动直流泵(或直流电机)启动,造成同轴严重扭曲,直至汽轮机损坏,损失是可想而知的。江西省某22万变电站,由于天气原因造成高压进线短路,使得主变压器着火燃烧,整个变电站失去交流电源,只能靠蓄电池供电来启动保护系统,但是由于蓄电池不能及时提供足够的电能,使得保护系统不能及时切断电源,启动保护设备。
Gemasolar发电站的聚光系统由26多个聚光镜面板组成,散布在185公顷的空地上。单个镜面板接收到的光能被积聚在的接收器,将熔盐罐加热,通过热传导形成高温压力蒸气,推动涡轮机发电。光照充足时产生的多余能量被熔盐罐储存,在缺少阳光的情况下释放能量,可继续向电网供电15小时,从而实现24小时全天候不间断发电。熔盐罐所存储的能量是多少?就需要通过超声波流量计来计量。目前,实践证明,能够计量这种高温流体的超声波流量(能量)计,只有flexim超声波流量(能量)计比较合适。
