应用范围:

SVG系列立式管道泵为单级、单吸、径向剖分式

离心泵。广泛用于石油化工、炼油厂、普通工业流程、煤化工和低温工程、供水及水处理、管线加压等行业。

输送介质:

各种液态石油化工产品、有机化合物及其它有腐

蚀性的原料和产品。

各种温度、浓度的酸性溶液、碱性溶液及盐溶液。

性能参数:

流量 Q :3~600 m3/h

扬程 H :4~200m

压力 p :0~2.5MPa(5MPa)

温度 t :-20℃~+250℃

型号说明:  

SVG100-250

SVG — 立式管线泵

100 — 泵排出口直径(mm)

250 — 叶轮名义直径(mm)

结构特点:

SVG系列泵型电机与泵之间带轴承架,由滚动轴承承受泵载荷,可使用在较高温度和较为重要的场合。

本系列泵型与相同性能的卧式泵比较,SVG泵的NPSH值较低。并且具有较小的占地面积和简单的管路连接,节省基础的投资费用。

本系列泵型的叶轮为单级、单吸、闭式叶轮。泵的轴向力通过叶轮前后耐磨环及平衡孔来平衡。

叶轮、泵体及泵盖带有可更换的密封环,轴封处带轴套,维修方便,节约备件费用

泵盖具有冷却或保温功能,可用于输送对温度有特殊要求的介质,同时泵盖带有放气塞,以便管路和泵工作前排气。

密封腔体尺寸适宜,可以采用填料密封和各种结构的机械密封,互换性好,改型费用低,并配有冷却、冲洗和密封液系统。

管线泵吸入、排出口法兰连接型式和法兰执行标准可根据用户要求变化,吸入排出口法兰额定压力等级相同,口径相同。

泵的转向:

从电机端看,泵为顺时针方向旋转。

Application Range:

Series SVG is single stage,single suction, radially split, vertical centrifugal inline pump. It is widely used for petrochemical industry, oil refinery, general industrial process, coal chemical industry, cryoge-

nic engineering, Water & Wastewater and pipeline pressure field and so on.

Pumping medium:

Various liquid petrochemicals, organic componds and other corrosive liquid.

  Acidic solution, alkaline solution and salt solution at various temperature and concentration.

Head        H: 4 to 200 m

Pressure      p: 0 to 2.5MPa5MPa

Temperature   t: -20 to +250

Description of pump type:

SVG100-250

SVG Vertical centrifugal inline pump

100 Discharge nozzle diametermm

250 Impeller typemm

Construction Features:

There is bearing bracket between pump and motor, and the pump force loading is borne by the rolling bearing, so that the pump could used for higher temperature and more important condition.

The SVG pump has lower NPSH compared with the other horizon-

tal pumps with the same performance, and its volume is smaller, so it needs smaller space for assembly at site. What’s more, its pipeline connection is simple, so the basis costs could be saved.

The SVG pump impeller is single stage, single suction and closed type. The axial force is balanced by the impeller front and rear wear ring, and the balance hole.

Impeller, pump casing and cover with interchangeable sealing ring, shaft seal with sleeve, easy to maintance, save spare parts cost.

Pump cover has the function of cooling and heating preservation. Which can be used for pumping mediums with special requirements, pump cover with ventilating plug, to vent the air in pipeline or pumps before operation.

Suitable dimension of sealing housing, use gland packing or vario-

us mechanical seal, good changability, low cost of size deviation, equiped with cooling, flushing, sealing liquid system.

The connection and standard of suction and discharge flange can be varied with customers requirements in rated pressure level and dimension.  

Pump Rotation:

Viewed from motor end, pump rotate in clockwise diameter.
