2、进口屏蔽式管道泵热水型主要供输送温度不超过160℃不含固体颗粒的软水之用,适用于能源、冶金、化工、纺织、造纸以及宾馆、饭店、浴室、锅炉热水增压循环输送及城市采暖系统循环等场合。

3、进口屏蔽式管道泵防腐型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。

五、进口屏蔽式管道泵工作条件

1、介质必须为软水、稀薄、不凝固、非易燃、不含固体颗粒及纤维的流体。

2、介质温度普通型80℃,热水型为120℃。

3、一般情况下系统工作压力不超过1.2Mpa,进口压力不小于0.5Mpa,特殊场合应事先与生产厂家联系。

4、环境温度不超过40℃,相对温度不超过95%。

九、进口屏蔽式管道泵维护

进口屏蔽式管道泵一般输送介质温度可达350℃,流量可达300m3/h,扬程可达115m,适用于热介质油和热水等高温液体。

1、定时记录电源电压的变化和电压的不平衡度。电源电压过高或过低,三相电压的不平衡造成电流的不平衡,都可能引起电机的过热或其它不正常现象。

2、定时记录电泵的负载电流和不平衡度。电泵发生故障时大多数会反映到定子绕组的电流的剧增,使电机过热。

3、定时记录管路中的输液温度,以确保实际的输液温度低于或等于铭牌上所规定的输液温度,避免电泵长期处于超温状态下运行,降低电机的使用寿命。

4、定时记录电泵进、出口端上的压力表数值,进口处力表的数值不得小于零,出口处压力表数与进口处压力表数的差值,必须符合牌上的规定的压力值。

5、电泵在每一次使用前要排气一次,在长期运行时,必须每星期排一次气,因为泵长时间运行,水分子在电泵内高速搅拌和撞击,同时被输送的介质带有一定的温度,造成液体浆产生。

6、注意电泵的气味,振动和噪声,电机的绕组因温度过高就会发出绝缘的焦味。一般的机械故障会反映为振动和噪声。因此发现异常应立即停电检查。

7、定时检查电泵循环液通路,过滤装置是否有阻塞现象。

8、定期维修测量石墨轴承和轴套之间的间隙,以确保定子屏蔽套与转子屏蔽套之间间隙均匀,运转可靠。
