          知識交流區--------------------------D礦用耐磨多級離心泵裝應該注意什么?
          安裝注意事項  1、安裝時管路重量不應承受在泵上,否則易損壞水泵;  2、安裝時必須擰緊地腳螺栓,且每間隔一定時段應對泵進行檢查防止其松動,以免水泵起動時發生劇烈振動而影響泵的性能;  2、安裝水泵前應仔細檢查泵流道內有無影響水泵運行的硬質物(如石塊、鐵砂等)以免水泵運行時損壞過流部件:  2、為了維護方便和使用安全,在泵的進出口管路上安裝一只調節閥及在泵進出口附近安裝一只壓力表,對于高揚程泵,為防止水錘,還應在出口閘閥前安裝一只止回閥以應付突然斷電等失去動力而生產的事故,從而確保水泵在最佳工況下運行,延長水泵的使用壽命;  2、泵用于有吸程場合,應裝有底閥,并且進口管路不應有過多彎道,同時不得有漏水、漏氣現象,以免影響水泵的吸入性能;  2、為不使雜質進入泵內而堵塞流道影響性能,應在泵進口前面安裝過濾器;  2、安裝管路前轉動水泵的轉子部件,應無磨擦或卡死現象,否則應將泵拆開檢查原因。

           
          150D30*7臥式多級離心泵,長沙東方工業泵廠優勢產品,十七年堅持生產臥式多級離心泵,傾力奉獻!

          流量:155立方米每小時(m3/h),揚程:210米(m),進出口徑均為:150mm,電機功率:160KW-4極。

          --------------------------多級泵效率計算公式及汽蝕余量、吸程概念
          什么叫多級泵的效率?公式如何?
          指多級泵的有效功率和軸功率之比。η=pe/p
          泵的功率通常指輸入功率,即原動機傳到泵軸上的功率,故又稱軸功率,用p表示。
          有效功率即:泵的揚程和質量流量及重力加速度的乘積。

          pe=ρg qh (w) 或pe=γqh/1000 (kw)     ρ:泵輸送液體的密度(kg/m3)
          γ:泵輸送液體的重度 γ=ρg (n/ m3)     g:重力加速度(m/s)
          質量流量 qm=ρq (t/h 或 kg/s)

          什么叫汽蝕余量?什么叫吸程?各自計量單位表示字母?
          泵在工作時液體在葉輪的進口處因一定真空壓力下會產生汽體,汽化的氣泡在液體質點的撞擊運動下,對葉輪等金屬表面產生剝蝕,從而破壞葉輪等金屬,此時真空壓力叫汽化壓力,汽蝕余量是指在泵吸入口處單位重量液體所具有的超過汽化壓力的富余能量。l單位用米標注,用(npsh)r。吸程即為必需汽蝕余量δh:即泵允許吸液體的真空度,亦即泵允許的安裝高度,單位用米。
          吸程=標準大氣壓(10.33米)-汽蝕余量-安全量(0.5米)

          易損件:首級口環(首級密封環)、次級口環(次級密封環)、軸套、導葉套、平衡環、平衡盤、平衡套、填料、機械密封、葉輪。材質:耐磨鑄鐵,鑄鋼,球鐵,不銹鋼等

          保質期:正常使用情況下,易損件保質半年,整機保質一年,配件供應充足。
