單螺桿泵調(diào)整參數(shù)有哪些手段 |
單螺桿泵調(diào)整參數(shù)有哪些手段
What are the parameters of a single screw to adjust the means
1) 無論改變泵出口管線結(jié)構(gòu)還是改變泵吸入口管線結(jié)構(gòu),都會對單螺桿泵的特性產(chǎn)生一定程度的影響。
1) Whether to change the pump outlet pipe structure or to change the pump intake pipe structure, and will feature a single-screw pump have a certain extent.
2) 改變泵排出口閥門開啟度,在一定范圍內(nèi)達(dá)到改變泵特性參數(shù)的目的,而且泵具有較高的工作效率。
2) changing the pump discharge outlet valve opening degrees, within a certain range to achieve the purpose of changing the pump parameters, and the pump with high efficiency.
3) 改變單螺桿泵吸入口閥門開啟度,當(dāng)吸入口真空度較小時,泵特性參數(shù)變化不大,而當(dāng)吸入口真空度較大時,泵的工作狀況急劇惡化。因此,這種方法不宜作為單螺桿泵調(diào)整參數(shù)的手段。
3) a change in single-screw pump suction valve opening degree, when the suction vacuum is small, pump parameters changed little, and when the suction vacuum is larger, the pump working conditions deteriorated dramatically. Therefore, this method is not appropriate as a single-screw adjusting parameters means. |
