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(huì)使軸套發(fā)熱，同時(shí)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(yīng)在運(yùn)行時(shí)予以調(diào)節(jié)。
裝配完成后，用手轉(zhuǎn)動(dòng)泵軸，沒有擦碰現(xiàn)象，轉(zhuǎn)動(dòng)比較輕滑均勻即可。
拆卸可按上述裝配順序相反地進(jìn)行。
1、檢查水泵和電機(jī)應(yīng)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(yùn)行時(shí)不發(fā)生汽蝕�；A(chǔ)尺寸應(yīng)符合泵機(jī)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(chǔ)上，用調(diào)整其間的楔形墊塊的方法校正水平，并適當(dāng)擰緊地腳螺栓，以防走動(dòng)；
(2)、在基礎(chǔ)與泵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(dòng)機(jī)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(jìn)出水管路及試運(yùn)行后再分別校核一遍，仍應(yīng)符合上述要求)；
(5)、在檢查電動(dòng)機(jī)轉(zhuǎn)向與水泵轉(zhuǎn)向相一致后，裝上聯(lián)軸器的聯(lián)接柱銷；
4、進(jìn)出水管路應(yīng)另設(shè)支撐，不得藉泵本體支撐；

ceed 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 easing and tighten it.
4. Feed the packing into the
packing box. Place the horizental join( paper gasket, cover the pump, hammar(or other
things) the taper pin with exteral 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, turn the rotor with hands, it should be
flexible 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)
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 its 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 concret into all the
foot bolt holes.
