核子反应堆全部的“硬件”——压力管,所有的管道,泵、冷冻剂(水)储备,通通放入第三个容器。
The entire "hardware" of the nuclear reactor - the pressure vessel and all pipes, pumps, coolant (water) reserves, are then encased in the third containment.
主要利用ANSYS软件对屏蔽泵密封垫的应力进行分析,计算出压力容器管板的最大应力和应变。
The stress for sealing washer of canned motor pump is analyzed by ANSYS software, and the maximum stress and strain of tubular sheet of press container are calculated.
研究结果表明,管径、含气率以及流体粘度对管泵系统的流量影响不大,而对压力降则有显著影响。
The results have shown that diameter, gas fraction and fluid viscosity have slight impact on flow rate of this boosting system, but have remarkable influence on pressure drop of this system.
同时,给出了在特定工况下,确定最佳母管压力和变频泵最佳频率的方法。
Simultaneously, it provides the method to determine the best pressure of header system and optimum frequency of variable frequency pump based on the special working condition.
如果立管压力的变化规律与泵冲数的变化规律不一致,预警解决方案就可以识别出来。
The alarm solution identifies changes in the SPP that are not consistent with the changes, if any, in SPM.
由于该泵进口管径合理,故其必须吸入压力较低。
液压阀开启有响应时间,定量泵系统启动时,瞬间压力冲击特别大,油管容易爆裂。变量泵启动时只有3mpa左右的待命压力,消除了爆管的隐患。
As there is certain response time for hydraulic valve startup, constant pump has to bear the momentary extremely high pressure impact with a high risk of oil pipe explosion.
