生的誤差,在用圓螺母和彈性墊圈壓緊轉(zhuǎn)子時(shí)須將彈性墊圈壓至極限點(diǎn),然后旋轉(zhuǎn)180°松開圓螺母。
1、檢查水泵和電機(jī)應(yīng)無損壞;
2、混凝土基礎(chǔ)應(yīng)牢固,表面光滑平整;
3、把地腳螺栓插入底座上的螺孔,把泵放在基礎(chǔ)上,用水平儀在軸端或出口端調(diào)整水平,在泵腳和基礎(chǔ)靠近地腳螺栓處必須墊墊塊;
4、泵調(diào)整好水平后,給地腳螺栓灌漿,堅(jiān)固后均勻地?cái)Q緊地腳螺栓,并重新調(diào)整水平,然后給底腳灌漿;
5、校正電機(jī)與水泵軸的同心度,使兩軸成一直線,兩聯(lián)軸器外圓上的不同心度允差為O.1毫米,端面間隙沿圓周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O.3毫米(連接進(jìn)出水管路后再分別校核一遍,仍符合上述要求);
6、在檢查電機(jī)轉(zhuǎn)向與水泵的轉(zhuǎn)向一致后,裝上聯(lián)軸器的聯(lián)接柱銷;
7、不要把泵本身作為管路支撐點(diǎn),管路應(yīng)在泵的附近設(shè)可靠支撐。
以上為不帶底座的水泵機(jī)組的安裝方法。
對(duì)于配帶公共底座的泵,基礎(chǔ)與底座之間保留4~5毫米的間隙,用調(diào)整螺釘精確地調(diào)整機(jī)組并在聯(lián)軸器處對(duì)中。其安裝原則與不帶公共底座的機(jī)組相同。
1、起動(dòng):
1)、起動(dòng)前的檢查:
a).泵或底座是否與基礎(chǔ)緊固;

rotation;
3. Heat the deep groove ball bearing and
fit it onto the shaft (sleeve) ;
4. For compensate differences in thermal
expansion between pump shaft and the components fitted on it. Tension the rotor
parts elastically with groove nut and disc spring. For this purpose tension the
disc spring to blocking point and then undo the grooved nut again by half a turn
180℃.
1. Chech whether the pump and the motor are
in good condition;
2. The concrete foundation must have
been set hard and the surface must be smooth and flat;
3. Loosely insert the foundation bolts
in the baseplate. Position the pump set on the pump set on the foundation and
align using a spirit level placed on the shaft or discharge nozzle. Shims must
always be fitted to the left and right of the foundation bolts in close
proximity to the bolts, between the baseplate or foundation frame and the
foundation itself.
4. After alignment, grout in the foundation bolts using
cement mortar. When the mortar has been set hard, uniformly tighten up the
bolts and re- cheek the alignment. Grout in the baseplate (non- shrinking
mortar is highly recommend-ed), ensuring that no cavities remain.
5. After the eoneret solidifed, again
correct the coaxial degree in the exeircle of the two couplings, the error of
the correction is not more than 0.1mm, the allowable error of the inhomogeneous
degree of the endfaee clearance along the circle is 0.3mm, Re-inspect the correct prieision after
tightening the foot unts, finally, pour
eoncret fuly nuder the foot of the pump and the motor except the around of the
wedge shaped cushion.
6. After cheek 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.
7. The inlet pipe and outlet pipe should
be supported by a brasket instead of the pump easing.
Above all the mentioned methods and requirements
are suitable for the pump set without common bedplate.
