IS离心清水泵解析

■ 用途及特点IS、IR型泵是卧式单级单吸清水离心泵，供吸送清水及物理化学性质类似水不含固体颗粒的液体。

它广泛适用于工农业及城市、排水、消防供水等。

IS、IR 型泵系根据国际标准IS02858 所规定的性能和尺寸设计，其技术标准均向国际标准靠拢，达到国际先进水平。

它是我国推广的节能泵类产品之一。

本泵结构简单，性能可靠，体积小，重量轻，抗汽蚀性能好，电耗低，使用维修方便。

IS、IR 型泵通用性广，全系列共140 种规格，但只用四种轴；同一规格的轴，轴承，轴封，叶轮紧固件等均能互换；全系列泵的悬架也只有四种。

泵转速分为2900 和1450 转／分两种。

性能如下：2900 转／分1450 转／分最大流量：240 米3／分400 米3／分最高总扬程：l25 米55 米最高转速：3500 转／分(用于60 调波电源时，叶轮直径有所减少)最高工作温度：80℃允许吸入管路压力0.3MPa，泵的最高使用压力 1.6MPa。

■ 型号意义说明■ 结构说明本泵为后开式，拆开泵盖和叶轮时不需拆卸吸水和排出管路。

悬架内装有两个滚珠轴承，用机器油或润滑脂润滑。

泵通过弹性联轴器由电动机直接驱动。

涡室、脚、进水法兰和出水法兰铸成一个整体。
