0.1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0.3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；
b)．聯(lián)軸器與泵機(jī)組是否校正；
c)．管路是否按要求連接；
d)．手是否能容易地轉(zhuǎn)動(dòng)轉(zhuǎn)子；
e)．是否所有軸承都有良好的潤滑。
2)、起動(dòng)前關(guān)閉出口閥，用介質(zhì)灌注排盡泵和管路內(nèi)的空氣。吸入狀況時(shí)，用泵體上部的螺塞排氣。在倒灌時(shí)泵也須排空；
2運(yùn)行：
1)、當(dāng)壓力表壓力升高，慢慢打開出口閥；
2)、打開所有輔助管路，并檢查流量；
3)、泵是填料密封運(yùn)行時(shí)，填料還處允許有多少量，滴水，輕輕壓緊填料壓蓋至少量滴水。
4)、為防止介質(zhì)升溫，泵不能在出口閥門

5. After the concret
solidifed, again correct the coaxial degree in the excircle of the two couplings,
the error of the correction is not more than O.1 mm, the allowable error of the
inhomo-geneous degree of the endface clearance along the circle is 0.3mm, Re- inspect the correct pricision after
tightening the foot unts, finally, pour
concret fuly nuder the foot of the pump and the motor except the around of the
wedge shaped cushion.
6. 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.
7. The inlet pipe and outlet
pipe should be supported by a brasket instead of the pump casing.
Above all the mentioned methods and requirements
are suitable for the pump set without common bedplate.
Samely, for the pump set with common bedplate.
Fit the pre -assembled set with foun-dation bolts loosely inserted in the cut-
outs in the foundation and align. There must be a 4-5cm gap between the top of
the foundation and the bottom of the baseframe. Precisely align the set using
the adjusting screws and check alignment on the coupling. Others you can refer
to the above mention methods.
1. Starting:
1 ). Before starting
up the pump make sure that the following requirements have been checked and fulfilled.
a). Has the pump been
firmly bolted to the base/foundation?
b) . Have the coupling
and pump unit been aligned as specified?
c). Are the pipes
properly fitted?
d) . Can the unit be
easily rotated by hand at the coupling? (Carry out at least one full rotation)
e). Has lubrication
been provided for oil-lubricated bearings?
2)Before the pump is
started up, it and the pipes must be vented and filled with the liquid to be
pumped. In the case of both gravity feed and suction operation venting must be
carried out via the hole on the upper suction elbow. In the case of suction
operation the upum must
