中文拼音 [yùzhēnkōngbèng]
預真空泵
英文
fore pump-
How many pumps were turned on should be based on the dynamic design according to project target. and how many pumps should be in operation in standard shut off procedure. it was approved that although the theoretical boundary of decline of groundwater level is 10m, the actual boundary is only about 6m
提出了一些與真空預壓加固地基設計相關的概念和處理方法，如定義真空預壓加固區場地形狀系數，提出按加固土體體積來確定射流泵數量、根據工程需要動態設計開泵量、增加停泵標準中對開泵量的規定等設計思想等，論證了真空預壓加固地基時地下水位下降的理論極限深度為10m ，而實際極限深度約為6m 。Based on the results of testing site, some problems of vacuum preloading was analyzed by plane strain finite element method. the relative stable seepage velocity field can be produced with the pumping time. the depth of negative pore - water pressure transferring increases with the pvds length
最後，對真空聯合堆載預壓的施工工藝進行了研究，提出了在真空聯合堆載預壓的中期，出水量已相對較少，可適當減少開泵量，並可採用停抽結合的變真空能量法，在不影響加固效果的前提下，可以大大節省用電量。The abnormal conditions of polyester vaccum system such as the frequent exchanging of liquid - ring pump in prepolycondensation, the occlusion of scraped condenser and vaccum atmospheric leg, the eg spray flow decreasing of vaccum injection pump, the working performance on the low side of the injection pump itself were analysed
摘要對聚酯真空系統的異常情況如預聚液環泵頻繁切換，刮板冷凝器、真空大氣腿堵塞、真空噴射泵eg噴淋流量降低，噴射泵本體工作性能偏低等進行了分析。Study on optimization matching of catcher and vacuum pump in vacuum cooling
