概 述GENERAL

S型泵是单级双吸卧式中开离心泵,供输送清水及物理化学性质类似于水的液体,液体最高温度不超过80°C,适合工厂、矿山、城市及电站的给排水,农田灌溉和各种水利工程。

S type pump is a single-stage double-suction horizontal spilt centrifugal pump and used to transport pure water and the liquid of both physical and chemical nature similar to those of water, the maximum temperature of which must not be over 80°C, suitable for water supply and drainage in factories, mines, cities and electric stations, waterlogged land drainage and irrigation of farming land and carious hydraulic projects.

结构说明about THE STRUCTURE

本型泵的吸入口和吐出口均在水泵轴心线下方,与轴线垂直呈水平方向,泵壳中开,检修时无需拆卸进水、排水管路及电动机(或其他原动机)。从联轴器向泵的方向看去,水泵为顺时针方向旋转,根据需要也可生产逆时针旋转的泵,但订货时应特殊提出。

Both inlet and outlet of this pump are placed under the axial line, horizontally and vertical to the axial line, the pump casing is opened in the middle, so it is unnecessary to remove the water inlet and outlet pipelines and motor(or other prime movers). The pump moves CW viewing from the clutch to it. The pump moving CCW can also be made, but it should be specially noted at order.

本型泵的主要零件有:泵体(1)、泵盖(2)、叶轮(3)、轴(4)、双吸密封环(5)、轴套(6)、轴承(15)等,除轴的材质为优质碳素钢外,其余均为铸铁制成。根据介质不同可换其他材质。

The main parts are: pump casing(1), pump cover(2), impeller(3), shaft(4), dual-suction seal ring(5), muff(6), bearing(15) etc. All of them, except the axle which is made of quality carbon steel, are made of cast iron. The material may be replaced with others upon different media.

叶轮经过静平衡校验,有轴套和两侧的轴套螺母固定,其轴向位置可以通过轴套螺母进行调整,叶轮的轴向力利用其叶片的对称布置达到平衡,可能还有一些剩余的轴向力则由轴端的轴承承受。

The impeller is static-balance calibrated, fixed with the muff and the muff nuts in both sides and its axial position can be adjusted via the nuts and axial force gets balanced by means of the symmetrical arrangement of its blades, there may be residual axial force which is borne by the bearing at the axle end.

泵轴由两个单列向心球轴承支撑,轴承装在泵体两端的轴承体内,用黄油润滑,双吸密封环用以减少水泵叶轮处泄露水。

The pump shaft is supported by two single column centripetal ball bearings,which are mounted inside of bearing body on both ends of the pump and lubricated with grease. The dual-suction seal ring is used to reduce the leak at the impeller.

水泵通过弹性联轴器与电动机直接传动。

The pump is driven directly by means of connecting to it via an elastic clutch.

轴封为填料密封,为了冷却润滑密封腔和防止空气漏入泵内,在填料之间装入填料环,水泵工作时少量高压水通过泵盖中开面上的梯形凹槽流入填料腔,起水封作用。

The shaft seal is packing seal land, to cool and lubricate the seal cavity and prevent air from getting into the pump, there is a packing ring between the packing. A small volume of high-pressure water flows into the packing cavity via the tapered beard during the pump's working to act as a water seal.
