3、ervices in agriculture, etc.The nomenclature of the model is based on its size and characteristic. For example:250 CS 65 A Impeller diameter once cut to meet the required parameters Head 65mSingle-stage, double-suction, horizontal centrifugal pumpDiameter of the suction nozzle is 250mm二 結構說明從聯(lián)軸器端看，C

4、S型泵均為順時針方向旋轉。用戶如需要逆時針方向旋轉的泵，必須在訂貨時特殊提出。CS型泵的主要零部件有：泵體、泵蓋、葉輪、軸、雙吸密封環(huán)、軸套、軸承部件與聯(lián)軸器部件等。除軸的材料為優(yōu)質碳鋼外，其余主要零件為鑄鐵制成。泵殼制成水平中開，泵的吸入口與吐出口均鑄在下半部泵體上，泵蓋以螺尾錐銷定位，與泵體配合。檢查泵殼內(nèi)部時，只要拆開泵蓋，毋須拆卸進出水管路。泵體的進出水法蘭上，有安裝真空表與壓力表的管螺紋孔。在進出水法蘭的底部有放水用的螺塞。葉輪經(jīng)過靜平衡校驗，用軸套與兩側軸套螺母固定在泵軸上，其軸向位置用軸套螺母進行調(diào)整。葉輪設計成對稱，液體從兩測進入葉輪，可以平衡軸向力，倘有剩余軸向力，則由軸端軸

5、承來承受。泵軸的兩側由軸承支承，軸承裝在軸承體內(nèi)，用黃油潤滑。泵以彈性聯(lián)軸器與電動機直接聯(lián)接。如泵用皮帶傳動，必須另設支架支承皮帶輪。雙吸密封環(huán)，以其與葉輪的間隙，來減少壓水室內(nèi)的液體漏回吸水室。密封環(huán)保護泵殼免于磨損，本身為易損零件，磨損后可以備件更換。軸封采用軟填料密封，為了冷卻潤滑密封腔和防止空氣漏入泵內(nèi)，在填料之間裝有填料環(huán)，水泵工作時少量高壓水通過泵蓋中開面上的梯形凹槽流入料腔，起水封作用。填料處液體的滲漏，以每分鐘10滴至20滴為適當。CS型泵的進水口徑小于300毫米（包括300毫米）或電動機功率小于90千瓦時，可配帶公共底座，訂貨時應予以說明。II. Construction V

6、iewed from the driving end, all the CS pumps are rotating in clockwise direction. Pumps of counter-clockwise rotation can only be supplied upon special request.The main components of CS pump are listed as follows: lower half casing, upper half casing, impeller, shaft, double suction sealing, shaft s

7、leeves, bearing housings and couplings.The volute casing is split on the horizontal centerline with the suction and discharge nozzle cast integral with the pump casing. The upper casing is accurately located on the lower half by the use of dowel pins. The upper casing can be removed to inspect the i

8、nterior of the pump without disturbing the pipe connections or pump alignment. The suction and discharge flanges contain tapped holes for vacuum and pressure gauge. At the bottom of the flanges, there are tapped plugs for water drainage.The impeller has been balanced statically. It is securely keyed

9、 to the shaft and adjusted to proper axial position by the shaft sleeves and external shaft nuts. The impeller is a double-suction enclosed type. It is hydraulically balanced by its inherent design. In case there is some slight residual thrust, it can be carried up by the bearing on the shaft end.Ea

10、ch pump shaft is provided with two roller bearing mounted in the bearing housings at both ends. They are single row, deep-groove type, being lubricated with grease.The flexible couplings connect the pump with the motor directly. For pumps driven by belt, there must be an intermediate bracket fitted

11、for supporting the belt pulley.The close running fit between the wearing rings and the impeller minimizes the leakage of water back into the suction part. The rings protect the casing from wearing and can be promptly replaced with the spare parts when they have been worn out.The shaft sleeves extend

12、 through the stuffing boxes. They protect the shaft from wearing. The sleeves can be renewable with the spare parts after worn out.The shaft seal is soft packing. The stuffing ring is fit between the packing in order to prevent air from leaking into the pump and to cool and lubricate sealing case, a

13、nd while the pump is working, a small amount of high-pressured water flows into the packing case through the concave notch on the pump cover to function as water seal. The appropriate leakage from the packing case is at 10 to 20 drops per minute. When the diameter of the suction nozzle is not larger

14、 than 300mm, or, the motor power is lower than 90kw/h, the pump set will be completed with common bedplate, which should be specified when an order is made. 三 裝配與拆卸1 裝配轉子部件：依次將葉輪、軸套、軸套螺母、填料套、填料環(huán)、填料壓蓋、擋水圈、軸承部件裝在泵軸上，并套上雙吸密封環(huán)，然后裝上聯(lián)軸器；2 分別檢查轉子部件上葉輪的密封部件外圓，軸套外圓徑向跳動應不超過下表的規(guī)定：名義直徑50501201202502505005008008

15、001250跳動量0.030.040.050.060.080.103 將轉子部件裝在泵體上，調(diào)整葉輪的軸向位置到兩側雙吸密封環(huán)的中間加以固定，將軸承體壓蓋由固定螺釘緊固。4 裝上填料、放好中開面紙墊，蓋上泵蓋，擰緊螺尾錐銷后，擰緊泵蓋螺母，最后裝上填料壓蓋。但不要將填料壓得太緊，填料過緊會使軸套發(fā)熱，同時耗用功率大；也不要壓得太松，填料過松液體滲漏大，水泵效率降低，所以應在運行時予以調(diào)節(jié)。裝配完成后，用手轉動泵軸，沒有擦碰現(xiàn)象，轉動比較輕滑均勻即可。拆卸可按上述裝配順序相反地進行。III. Assembly and Disassembly1. Assemble keys, impeller,

16、sleeves, sleeve nuts packing rings, and block water ring in order onto the pump shaft. Afterwards add the suction seal ring, and then the bearing part and coupling.2. Individually inspect the radial run-out of the excircle of both the impeller seal and the sleeve on the rotor part, which is not allo

17、wed to exceed its provisions as follows:Nominal Diameter50501201202502505005008008001250Run-out0.030.040.050.060.080.103. Assemble the rotor part and studs onto the pump casing, and well install the bearing gland and tighten it with bolts, then you can adjust the axial position of the impeller with

18、shaft sleeve nuts up to middle flow passage of the pump casing and tighten it.4. Feed the packing into the packing box, place the paper lining, cover the pump, hammer the taper pin tightly with external thread. Screw the nuts on the pump cover and mount the packing gland. Tightness of the packing mu

19、st be suitable (if too tight, the shaft sleeve would be over heated, and more power would be consumed; if too loose, the leakage of liquid would occur from here, and thus would decrease the pump efficiency.)5. After finish assembling the pump, turn the rotor with hands, it should run flexible and sm

20、ooth without blocking and rubbing. That is OK! And then you can operate it freely.(Disassemble it according to the reverse order of assembling)四 安裝1 檢查水泵和電機應無損壞；2 水泵的安裝首先要滿足裝置汽蝕余量NPSHa大于泵的必須汽蝕余量NPSHr，使泵在運行時不發(fā)生汽蝕?；A尺寸應符合泵機組的安裝尺寸；3 安裝順序：（1） 將水泵放在埋有地腳螺栓的混凝土基礎上，用調(diào)整其間的楔形墊塊的方法校正水平，并適當擰緊地腳螺栓，以防走動；（2） 在基礎與泵

21、底腳之間灌注混凝土；（3） 待混凝土干固后，擰緊地腳螺栓，并重新檢查水泵的水平度；（4） 校正電動機軸與水泵軸的同心度，使兩軸成一直線，在兩聯(lián)軸器外圓上的不同心度允差為0.1毫米，端面間隙沿圓周的不均勻允差為0.3毫米（在聯(lián)接進出水管路及試運行后再分別校核一遍，仍應符合上述要求）；（5） 在檢查電動機轉向與水泵轉向相一致后，裝上聯(lián)軸器的聯(lián)接柱銷；4 進出水管路應另設支撐，不得藉泵本體支撐；5 水泵與管路之間的結合面應保證良好的氣密性，尤其是進水管路必須保證嚴格的不漏氣，并且在裝置上無窩存空氣的可能；6 如水泵安裝在進水水位以上時，為了灌泵起動，一般可裝底閥，也可采用真空引水方法；7 水泵與出水

22、管路之間一般需裝閘和止回閥（揚程小于20米的可不用）。止回閥裝在閘后面。以上所述的安裝方法是指不帶公共底座的水泵機組。對配帶公共底座的泵機組的安裝，只要調(diào)整底座與混凝土基礎之間的楔形墊鐵來校正泵機組的水平，然后于其間灌注混凝土。其安裝原則與要求和不配帶公共底座的泵機組安裝相同。IV. Installation1. Check whether the pump and the motor are in good condition.2. Make sure that the value of NPSH must be greater than the one that have been giv

26、ith that of the pump, you can install the connecting parallel pin of the coupling.4. A bracket instead of the pump casing should support the inlet pipe and outlet pipe.5. The combination between the pump and the pipe must be kept good sealing, especially no leakage of air occurs from the inlet pipe

27、and no air possibly remained in it in the cause of installation.6. If the pump is installed above the suction water level. It should be equipped foot valve for pouring water and driving and it also can suck water by a vacuum pump. All the above-mentioned methods and requirements are suitable for the

28、 pump set without common bedplate; for the pump set with common bedplate, you can also refer to the above mention methods.五、起動、停止和運行1 起動與停止：（1） 起動前，轉動泵機組轉子應該輕滑均勻；（2） 關閉出水閘閥，灌泵（如無底閥則用真空泵抽空氣引水），要保證泵內(nèi)充滿水，無空氣窩存；（3） 如果泵上裝有真空表或壓力表，要關閉其與泵連接管路上的旋塞再起動電動機，待轉速正常后再打開；然后逐漸打開出水閘閥，如流量過大，可以適當?shù)仃P閉閘閥進行調(diào)節(jié)，盡量使泵運行工況接近泵的設

30、其他不正常的聲音時，應立即停車，檢查原因，加以消除；（6） 不得任意提高泵的轉速，但可降低轉速，如本型泵額定轉速n，流量Q，揚程H，功率N，倘若降低轉速為n1，則流量為Q1，揚程為H1，功率為N1，其相互關系可用下列公式換算：Q1= Q()、 H1= H、 N1= NV. Starting Stopping and OperationStarting and stopping:1. Before starting, turn the rotor, it should run flexible.2. Close the discharge valve, pour water into the p

31、ump (if no foot valve, use a vacuum pump for sucking water instead). Be sure the pump is full of water and no air remained in it.3. If there is a vacuum gauge installed on the pump, the cocks on the pipes should be turned off. Then start the motor. It is not allowed to turn on the discharge valve un

32、til the running speed is normal, and then open gradually the brake valve until the sucked water of the two sides reach balancing.4. Screw properly the nuts on the packing gland so as to minimize the leakage of liquid as little as possible, at the same time, pay attention to the temperature rise of t

33、he packing case. 5. Before stopping the pump, first turn off the cocks of the vacuum gauge and manometer and the brake valve on the discharge pipe. If the ambient temperature is low, the coach under the pump casing should be loosened to drain away the rest water so as to keep the pump casing from be

If it will not be used for a long time, the pump must be disconnected and all the parts should be kept dry, and smeared on the machining face with rust-proof grease oil.Running:1. The temperature of the pump bearing should not exceed 75.2. The suitable amount of the good Ca-bas

35、ed grease used to lubricate the bearing occupies 1/3 to 1/2 space of the bearing body, and it should be changed periodically.3. When the packing became worn, tighten the packing gland properly or change it if it is necessary.4. Check the flexible coupling part, be watchful to the temperature rise of

36、 motor bearing. 5. During operation, if any noise or abnormal sounds are heard, stop the pump immediately, and find out the cause, then clear up.6. It is not allowed to increase the running speed wantonly, but you can decrease the running speed of the pump for the purpose of working. The performance
