合后(逆时针方向),装上联轴器的联接柱销:

    4、进出水管路应另设支撑,不得藉泵体支撑;

    5、水泵与管路之间的结合面应保证良好的气密性,尤其是进水管路必须保证严格的不漏气,并且在装置上无窝存空气的可能;

    6、如水泵装置在进水水位以上时,为了灌泵起动,一般可装底阀,也可采用真空引水方法;

    7、水泵与出水管路之间一般需装闸阀和止回阀(扬程小于20米的可不用)。止回阀装在闸阀后面。

    以上所述的安装方法是指不带公共底座的水泵机组。

    对配带公共底座的泵机组的安装,只要调整底座与混凝土基础之间的楔形垫铁来校正泵机组的水平,然后在其间灌注混凝土。其安装原则与要求和不配带公共底座的泵机组安装相同。

五、起动、停止和运行

  1、起动与停止:

  (1)、起动前,转动泵机组转子应该轻滑均匀;

  (2)关出水闸阀,灌泵(如无底阀则用真空泵抽空气引水),要保证泵内充满水,无空气窝存;

  (3)、如果泵上装有真空表或压力表,要关闭其与泵连接管路上的旋塞再起动电动机,待转速正常后再打开,然后逐渐打开出水闸阀.如流量过大,可以适当地关闭闸

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.

  (2) After the eoncret solidifed, again correct the coaxial degree in the excircle of the two couplings, the error of the correction shoud be  not  more that O.1mm,  the allowable error of the inhomogeneous degree of the endface clearance along the circle is O.3ram, Re - inspect the correct prieision after tightening the foot nuts, finally, pour concret fully under the foot of the pump and the motor except the around

of the wedge shaped cushion.

  (3)  After checking 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 easing.

   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 wate level,  it should be equipped foot valve for pouring ware and driving and it also can suck water by suction vacuunl.

   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 cau refer to the above mention methods.

V. Starting stopping and running

   a. Starting and stopping:

   1. Before starting,  turn the rotor,  it should be flexible.

   2. Close the discharge valve, pour wate in it (if no foot valve, draw water inside with a vacuum pump).Be sure the pump is full of water and no air remained in it.

   3. If there is a vacuum gauge installed on the
