【摘要】：高揚(yáng)程泵站因流量大、揚(yáng)程高,在事故工況時(shí)極易發(fā)生嚴(yán)重的斷流彌合水錘。以水錘分析為基礎(chǔ),結(jié)合工程實(shí)例,并通過(guò)數(shù)值模擬對(duì)事故工況時(shí)高揚(yáng)程泵站的水力過(guò)渡過(guò)程進(jìn)行計(jì)算分析,結(jié)果表明:采用調(diào)壓塔+空氣閥+泵端液控蝶閥防護(hù)效果最佳,將單向調(diào)壓塔裝設(shè)在起伏管道的最高點(diǎn)可有效消除負(fù)壓和降低停泵水錘帶來(lái)的升壓。
[Abstract]:Due to the large flow and high lift, the high lift pump station is prone to serious water hammer in the accident condition. Based on the water hammer analysis, the hydraulic transition process of the high lift pump station is calculated and analyzed by numerical simulation. The results show that the pressure regulating tower + air valve + pump end hydraulic butterfly valve protection is adopted. The effect is the best. Installing the one-way surge tank at the highest point of the undulating pipeline can effectively eliminate negative pressure and reduce the pressure brought by the water hammer.
