          產品詳細說明

           
          125D25*3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:101立方米每小時(m3/h),揚程:64.5米(m),進出口徑均為:125mm,電機功率:30KW-2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。
