結構特點:

VLC型立式長軸泵入口垂直向下,出口水平,單基礎安裝。

1、泵進口裝有濾網,開孔大小適當,既有效地防止大顆粒雜質進入泵內損壞水泵,同時又保證了凈進水面積,最大限度減少進口損失,提高了泵效率。

2、充分考慮了葉輪及導葉的抗磨、耐腐蝕性,使葉輪等易損件壽命提高;葉輪和導葉體為多級,適應不同揚程要求。

3、葉輪采用平衡孔平衡軸向力,葉輪前后蓋板均設有可更換的特殊堰堤型密封環,保護葉輪及泵體。有效防止泵停機后雜質沉淀至密封環間隙進口處,極大提高密封環和葉輪的使用壽命。

4、泵中間軸、揚水管和護管為多節,中間接軸采用套筒聯軸技術,徑向同軸度提高,整機振動減??;揚水管數量可根據用戶需要的液下深度增減,適應不同的也下深度要求。

Operation range:

VLC vertical long shaft pump is widely used for water treatment, sewage water treatment, power plant, Iron and steel industry, mining, public engineering, irrigation, and water conservancy and so on. It can also be used to transport clean water and sewage water which is contain some solid particle( scrap iron, gravel, braize), corrosive industrial sewage water, sea water, the temperature of transport liquid can not exceed 80.

 

Performance range:

Capacity  Q:608400 m3/h     

Head    H:12.594.5 m

Construction Feature

VLC vertical long shaft pump’s suction straight down, discharge horizontal , single basic installation.

  1. Pump suction installs filter, and with suited hole,  it not only prevent the bigger particle enter into pump and broken pump, but also ensure inflow water area.  Lower suction loss, improve pump efficiency.

2. Take a full Consideration of the impeller and vane abrasion resistance, extend the life of  impeller and other wear parts.  Multistage Impeller and defuser are adapt to varies head .

3. The Impeller can balance its’ axial force by balance hole, there is replaceable special dam type seal ring installed the throatbush and frame plate liner insert that can protect impeller and casing. It can prevent impurity sediment enter into the suction seal ring gap, this can exceed the using life of seal ring and impeller.

4. Middle shaft, water pipes and protective tube are knobby.middle shaft used sleeve coupling technology, improve radial direction and shaft grade, it can reduce pump vibration. The quantity of water tube can be supplied according the customer need the under water.

5、泵揚水管由法蘭連接,中間有導軸承。導軸承采用加強型填充聚四氟乙烯,也可采用丁腈橡膠(用于介質溫度高于55)。

6、軸由護管保護,當輸送清水時,可取消護管,導軸承不必接冷卻潤滑水;輸送污水時,導軸承需外接冷卻潤滑水。

7、傳動軸長度合理,剛度足夠,整機臨界轉速是泵轉速的3倍以上,泵絕不共振。

8、泵的軸封為填料密封,也可以采用機械密封,軸封及導軸承處裝有可更換的軸套,以保護軸。

9、泵的殘余軸向力和轉子部件的重量由泵自身的推力軸承承受或帶推力軸承的電機承受。推力軸承用稀油潤滑,采用自然冷卻或外接水進行冷卻。

10、葉輪的軸向位置由軸承部件上端或泵聯軸器內的調整螺母來調整,十分方便。

11、水泵可配備控制柜,它具有根據液位自動啟停和過載報警及實時遠程監控等多種功能,可實現多泵聯網遠程集中控制??趶酱笥?/span>500mm的泵設有自動排氣系統。

泵的轉向:

  泵和電機直聯,從電機端俯視泵為逆時針方向旋轉。

網的損失按每10m損失1.5M估算。

5. Water tube in pump connect by flange, install guide bearing in the middle. The material for guide bearing is  PTFE or nitrile rubber ( it used in the medium that the temperature is higher than 55).

6. Shaft is protected by protective tube, when transport clean water,  cancel the protective tube, the guide bearing don’t need to connect cooling lubrication water. When transport waste water, guide bearing need cooling lubrication water.

7. Suitable length rotor shaft, enough rigidity, complete machine’s critical speed is 3 times higher  than pump speed, pump has no resonance .

8. Pump shaft seal is packing seal, mechanical seal can also be taken. There is replaceable shaft sleeve installed during shaft seal and guide bearing, this can protect the shaft.

9. Pump residual axial force and rotor parts weight can be bear by its’ own thrust bearing or motor that have  thrust bearing  . The thrust bearing can be lubricated by thin oil, cooling by exterior water or by itself.

10. Axial position of the impeller can be adjusted by the nut on the top of bearing unit or in the pump coupling .it  is  very convenient.

11. Pump can be installed with control cabinet which obtain Auto start-stop, over load alarm and  Real-time remote monitoring function and so on, it can achieve  multiple pump connected to the remote centralized control . There is self-motion venting system installed if the pump caliber exceed 500mm.

Pump rotation:

Pump connected the motor directly. Pump rotation is anticlockwise when overlook from the motor end.

Model selection introduction:

You can reference to the performance parameter list, the specification listed is :in a atmospheric , the test performance for normal temperature clean water without lifting tube and strainer. When calculating installation head, the loss of lifting tube and strainer can according to 1.5M loss every 10m.
