不飞则已,一飞冲天;不鸣则已,一鸣惊人。——司马迁
进水塔渗漏水量较小时,经过一定时间的积累,达到主用潜水泵启动水位2.40m,用主用潜水泵D3进行排水;当水量增大时,达到备用潜水泵启动水位2.60m,增加备用潜水泵D4进行排水;在此过程中,若水位回落到停泵水位1.5m时,则停止潜水泵;若水量进一步增大,以致达到主用离心泵启动水位2.80m和备用离心泵启动水位3.00m时,则分别启动主用离心泵D1和备用离心泵D2进行排水。此时潜水泵作为离心泵的充水泵,同时启动潜水泵D3、D4,打开充水电磁阀Z1(或Z2),延时3分钟左右并且达到一定压力要求后启动离心泵并打开排水电动阀门F1(或F2)进行排水,然后关闭潜水泵D3、D4和电磁阀Z1(或Z2)。在排水过程中,若水位回落到停泵水位1.50m,则关闭离心泵。在关闭离心泵时,要先关闭相应的电动阀F1或F2,然后再关闭离心泵。其渗漏排水设备布置如图1所示。
