启动、运转与停机START,OPERATION,STOP

1、启动前的准备工作:

(1水泵转动部分轴向串量的调整:

水泵工作时,由于受轴向水推力的作用使传动轴产生伸长,调整轴向串量的目的是消除这一影响,保证泵正常工作。调整的方法是:旋转安装在传动装置轴上的调整螺母,将轴提升。由于传动轴因自重的作用由刚提升时受压而变为受拉状态,本身有一定伸长量,所以在旋转调整螺母的同时,不断向逆时针方向转动传动装置轴,当转动由很沉变为较轻且无反弹力时,则可认为叶轮端面与壳体刚刚离开。这时调整螺母的位置即为调整轴向串量的“起点”。从“起点”开始再转动调整螺母将轴提升的量即为“轴向串量”。不同的泵型或安装深度不同,应提升的轴向串量不一样,各种泵应提

升的“轴向串量”参见表1中“转子量小提升量”。应注意的是,“起点”不能一次就确定,应反复找几次为妥。同时,在开车以后正常投入运行之前,“串量”应重新调整,串量调好后就用螺钉将调整螺母固定。

(2预润:

在水泵启动之前,必须从泵座上的注水孔向扬水管内注入清水润滑橡胶轴承。当泵装有底阀时,必须将扬水管注满。无底阀时,灌入的水不得少于0.2m3,有条件时,应接通自来水或予润滑水箱,从开车前5分钟进行予润,到启泵上水后停止供水。

(3检查:

a、检查传动装置中的止逆装置是否有效;

b、检查转向是否符合要求,正确的转向是:从传动装置向下看,应为反时针方向旋转;

c、传动装置中润滑油或油脂是否按规定灌注完毕;

d、电器部分是否符合有关规定?是否与电机容量相适应。

在以上准备工作完成之后,将出口阀稍稍开启一点,即可启动水泵。

1.Before you start work:

(1The adjustment for the axial string of pump rotating part:

When pump works,because of the role of the axial hydraulic thrust,the driver shaft is extended,and the purpose of adjusting the axis string quatity is to eliminate this effect to make the pump’s normal work.Adjustment methods are:rotate the adjusting nut mounded on the transmission device shaft,and upgrade the shaft.Due to the role of weight,the shaft from the beginning of the state of press becomes the state of tension,itself has a certain amount of elongation,so as the same as ratating the adjusting nut,you should keep the

transmission device counterclockwise rotation,when turning from much heaviness becomes less and no rebound force, the impeller end surface and the shell can be considered just left.Then the location of adjusting nut is the"starting point”of the adjustment axis string quantity.From the"starting point"and then start turning the adjusting nut to make the quality of shaft upgr aded is“axis string quantity”. Different pump or different installation depth,the axis string quantity should upgrade not the same, "axial string quantity"which is upgraded for the various pumps refers to“the small quality of rotation to be upgraded”of tab le1,It should be noted that the"starting point"is not once determined,you should find several times.Meanwhile,After starting-up and before the normal operation,”string quantity”should be re-adjusted,and after a good adjustment of string quantity

,you will fix the adjusting nut with the screw.

(2Lubrication preparing:

Before starting the pump,you should inject water into the pipe of pumping water from water hole to lubricate rubber bearings.When the pump has not a bottom valve,you should pour into the water not less than0.2m3,If it is permissible,you should connect the tap water or water tank for providing lubricaton,and lubricate5minutes before

driving,until starting the pump to feed water,then stop suppling water.

(3Check:

a,check the non-return device of gearing whether is valid;

b,check the turning whether meeting the requirements,the right turning is:looking down from the gearing,it should be anti-clockwise;

c,oil or grease in the gearing whether pouring completly according to the regulations;
