一、概述
ISG是立式循环单X单吸管道离心泵,主要用于抽取类似于清水的介质,ISG系列的泵可分为管道离心泵,热水泵,化工泵,油泵和低转速离心泵,用途十分广泛,安装方便,采用IS型离心泵和SG型管道泵之性能参数,在一般立式管道泵的基础上进行巧妙组合设计而成。
1、ISG型立式管道离心泵,供输送清水及物理化学性质类似于清水的其他液体之用,适用于工业和城市给排水、高层建筑增压送水、园林喷灌、消防增压、远距离输送、暖通制冷循环、浴室等冷暖水循环增压及设备配套,使用温度T<80℃。
2、IRG型立式热水管道泵广泛适用于:能源、冶金、化工、纺织、造纸、以及宾馆饭店等锅炉高温热水增压循环输送及城市采暖系统循环用泵,IRG型使用温度T<120℃。
3、IHG型化工泵,供输送不含固体颗粒,具有腐蚀性,粘度类似于水的液体,适用于石油、化工、冶金、电力、造纸、食品制药和合成纤维等部门,使用温度为-20℃ ~ 120℃。
4、YG型立式管道离心油泵,供输送汽油、煤油、柴油等石油产品,被输送介质温度为-20℃ ~ + 120℃。
二、型号含义
IRG80-160(I)(A)(B)(C)
IRG——单X单吸热水离心泵
80——泵进出口直径
160——叶轮名义直径
I——流量分类
A——叶轮X一次切割
B——叶轮X二次切割
C——叶轮X三次切割
叶轮切割次数代表着流量越来越小。
三、IRG20-110热水循环泵的特点
1、IRG20-110热水循环泵为立式结构,进出口口径相同,且位于同一中心线上,可象阀门一样安装于管路之中,外形紧凑美观,占地面积小,建筑投入低,如加上防护罩则可置于户外使用。
2、IRG20-110热水循环泵叶轮直接安装在电机的长轴上,轴向尺寸短,结构紧凑,泵与电机轴承配置合理,能X地平衡泵运转产生的径向和轴向负荷,从而保证了泵的运行平稳,振动小、噪音低。
3、IRG20-110热水循环泵轴封采用机械密封或机械密封组合,采用进口钛合金密封环、中型耐高温机械密封和采用硬质合金材料,耐磨密封,能X地延长机械密封的使用寿命。
4、IRG20-110热水循环泵安装检修方便,无需拆动管路系统,只要卸下泵联体座螺母即可抽出全部转子部件。
5、IRG20-110热水循环泵可根据使用要求即流量和扬程的需要采用泵的串、并联运用方式。
6、管道离心泵可根据管路布置的要求采用泵的竖式和横式安装。
