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.
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。)
介绍英语泵的主要零件有: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。)
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.)

3装配与拆卸
1.装配转子部件:依次将键、叶轮、轴套、轴套螺母、填料压盖、挡水圈装在轴上,套上双吸密封环,装上轴承部件和联轴器。人教版一年级语文上册
2.分别检查转子部件上叶轮的密封部位外圆及轴套外圆的径向跳动,不超过下表规定:
名义直径≤50>50-120>120-260>260-500>500-800>800-1250跳动量0.060.080.100.120.150.20
3.将转子部件和螺柱装在泵体上,装好轴承体压盖。用轴套螺母调整叶轮的轴向位置到泵体流道的中间,加以固紧。
4.装上填料,放好中开面纸垫,盖上泵盖,拧紧螺尾锥销拧紧泵盖螺母。压紧填料压盖。但不要将填料压得太紧。过紧会使轴套发热,同时耗能增多;民不要压得太松,过松会使液体渗漏大,水泵效率降低。
5.装配用手转动转子,无卡擦、轻滑均匀即可。
6.拆卸可按上述装配顺序相反进行。宝笔顺
Assembly and disassembly
(Please use the following procedures to assemble)
1.Assemble keys. Impeller sleeves, sleeve nuts packing rings, and block water ring in order on the pump shaft. Afterwards sleeve the suction seal ring, and then the bearing part and coupling.
2.Individully inspect the radial beats of the excircle of the impeller seal position and the sleeve excircle on the rotor part, which is not allowed to exceed its provisions as following:
3.Assemble the rotor part and studs on the pump casing, and well install the bearing gland and tighten it with bolls, then you can adjust the axial position of the impeller with shaft sleeve nuts up to middle flow passage way of the pump casing and tighten it.
4.Feed the packing into the packing box. Place the horizental joint paper gasket, cover the pump, hammar(or other things) the taper pin with external thread tightly, the following, screw its nuts and mount the packing gland which degree of the packing tightness must be suitbale(if too light, the shaft sleeve would be over heated, samely more power would be consumed; if too loose, the leakage of liquid would be found from here, and thus would decrease the pump efficiency.)
5.After finish assembling the pump, tum the rotor with hands, it should be fiexible and smooth as well as no block and no rubbing, that is OK! And then you can operate it freely.
(Disassemble it according to the opposite order of assembling)

Installation
阅读的历史1.Check whether the pump and the motor are in good condition.
2.Make sure that the value of NPSH must be higher than the one that have been given, and ist foundation dimensions should be in comformity with the installation drawing.
3.The steps of installation:
(1)Sleeve the foot bolts and hat the nuts on the pump and the motor, place the pump on the concret foundation where some foot bolt holes are pre=built, correct the horizental and the coaxial degree between the pump shaft and the motor shaft by means of adjusting the wedge=shaped cushion, then fully pour the concrete into all the foot bolt holes.
(2)After the concret solidifed, again correct the coaxial degree in the excircle of the two couplings, the error of the correction is not more that 0.1mm, the allowable error of the inhomogeneous degree of the endface clearance along the circle is 0.3mm, Re-inspect the correct precision after tightening the foot nuts, finally, pour concrete fully under the foot of the pump and the motor except the around of the wedge shaped cushion. (3)After check the rotary direction of the motor which is now in keeping with that of the pump, you can install the connecting parallel pin of the coupling.
4.The inlet pipe and outlet pipe should be supported by a brasket instead of the pump casing.
5.The combination between the pump and the pipe must be keeping good sealing, especially no leakage of air occures from the inlet pipe and no possible remained air in it in the cause of installation.6.If the pump is installed above the suction water level, it should be equiped foot valve for pouring water and driving and it also can suck water by suction vacuum.
Above all the mentioned methods and requirements are suitable for the pump set without common bedplate; samely, for the pump set with common bedplate, you also can refer to the above mention methods.
