潜水泵安全操作技术 | 2011-5-7 7:42:00

一、起动前检查:

1、水管应结扎牢固;

2、放气、放水、注油等螺塞均应旋紧;

3、叶轮绝缘应良好。

二、工作电压在342418V范围内。

三、电泵应放在坚固的网篮内放入水中,以防乱草杂物轧住叶轮,其沉入水中最浅深度为0.5m,最深不超过3m;应直立水中,不得陷入泥中,以防因散热不良而烧坏。

四、电泵放入水中或从水中提出,须拉住扣在电泵耳环上的绳子,严禁提拉电缆。出水管以能套上电泵管接头为宜。

五、接好电源后,先试运转,检查旋转方向是否正确。电泵在水外运转的时间不得超过5,以防过热。

六、电泵应装设接零保护或漏电保护装置,工作时,周围30m以内不得有人畜进入。

七、停转后不得立即再启动。每小时启动不得超过十次。停机后再间隔1秒以上才能开机。在运转中如发现声音不正常,应立即切断电源进行检查。

八、新电泵或新换过橡胶密封圈的电泵使用50小时后,应旋开放水封口塞检查泄漏量(流出的水和油),如不超过5ml说明密封正常。若超过5ml,应进行196kpa2kgf/cm2)的气压试验。检查泄漏原因后,予以排除。以后每月检查一次,若泄漏不超过25ml,可以继续使用。检查后必须旋开放油封口塞倒出油室内的储油,换上规定的润滑油。

九、经过修理的油浸式潜水泵,应先进行196kpa(2kgf/cm2)气压试验,检查各部无泄漏现象,然后将润滑油加入上、下壳体内。

十、电泵使用的地点气温低于0时,在停止运转时,应从水中提出电泵擦干后存放室内。

十一、每周应测定一次电动机定子绕组对地的绝缘电阻有无下降。
