S型单级双吸离心泵（中开泵）-广州广一泵业有限公司

S型泵执行标准 Q/GYGZ56-2008

概述
S型单级双吸泵为中开式离心泵，供抽送清水或物理化学性质类似于水的其它液体之用。被输送液体温度不得高于80℃，适用于工厂、矿山、城市给水、电站、农田排灌和各种水利工程。

结构说明
本型泵的吸入口与吐出口均在水泵轴心线下方，与轴线垂直成水平方向。检修时无需拆卸进出口水管及电动机。从传动方向看去，水泵为顺时针方向旋转（根据用户需要亦可改为逆时针方向旋转。）
泵的主要零件有：泵体、泵盖、叶轮、轴、双吸密封环、轴套等。除轴的材料为优质碳钢外，其余主要零件为铸铁制成。
泵体与泵盖构成叶轮的工作室。在进出水法兰上，制有安装真空表和压力表的管螺孔。进出水法兰的下部，制有放水的管螺孔。
经过静平衡校验的叶轮，用轴套和两边的轴套螺母固定在轴上，其轴向位置可通过轴套螺母进行调整。叶轮的辆向力利用其叶片对称布置、两面进水达到平衡。
泵轴由两个单列向心球轴承支承。轴承装在轴承体内，安装在泵体两端，用黄油润滑。
双吸密封环用以减少水泵压水室的水漏回吸水室。
泵通过弹性联轴器由电动机直接传动，必要时亦可用内燃机转动。
轴封采用软填料密封时，为了防止空气进入泵内和冷却润滑密封腔，在填料之间装有填料环，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。（根据用户需要亦可改装机械密封。）

Brief introduction
Series S Pumps are a single stage, double suction and axially split centrifugal pump and are used to pump clean water or Similar liquids in physical cal and chemical properties. The temperature of the pumped liquid should not be exceeded 80℃. And The pump is mainly suitable for water supply in factories, mines, cities, hydropower stations, various conservancy projects and irrigation in farms,ets.

Construction description
The inlet and outet of the pump are both under the centreline of the pump shaft, they are vertical to the shaft centreline andgo to horizental direction. You needn't dismount the outlet and inlet pipes for inspection. Looking from the driven direction therotaty direction is clockwise(Or can change to counterwise as user's requirement).
Main parts of the pump:(1)Pump casing (2)Pump cover (3)Impeller (4)Shaft (5)Double suction seal ring (6)Shaft sleeve, etc. They are made of cast iron except the shaft material being made of fine steel.
The impeller working house is composed of pump casing and pump cover. The threaded holes for installing the vacuum gauge and manometer are separately located at the suction flange and the discharge flange. At the bottom of the inlet or outlet flange a drain threaded hole equiped here.
The impeller checked by statical equilibrium is fixed on the shaft by the shaft sleeves and the shaft nuts, which axial position can be adjusted by the sleeve nuts. And for the axial force of the impeller, it can be adjusted by using the symmtrical distribution of the impeller and the balance of the two sides water.
The pump shaft is supported by two single redial ball beatings.
The bearing fitted on the ends of the pump casing is installed in the bearing body and is lubricated by oil grease.
The double suction seal ring is used to reduce the leaking water from the pressure water house which would flow back to the suction water house.
The pump is driven by the moto though the flexible coupling(It also can be driven by diesel engine if it is necessary)
The shaft seal is soft stuff. The packing ring is installed among the packings in order to prevent air from coming into the pump and cooling lubricating sealing case, and while the pump working, it is allowed to let a little high-pressure-water going through the trapeziform concave groove on the horzontally split face of the pump cover and flow into the packing case, function as wate seal(Mechanical seal is available as the customer's requirement.)
