2 Introduction to the basic principle of the equipment

PP fiber filter element: unique outer loose and inner tight structure, can effectively remove suspended matter, sediment, and particulate impurities above 5micron or 1micron (determined according to the pore size of the PP fiber filter element) in the water source; effective activated carbon filter element: has a very strong Adsorption and filtration performance can effectively remove impurities such as color, odor and organic matter in distilled water.

Activated carbon filtration: chemical adsorption to remove chlorine, organic adsorption to remove soluble organic matter. Because the reverse osmosis membrane is sensitive to chlorine and soluble organic matter, carbon columns are often placed in front of the RO membrane to remove these substances.

Reverse Osmosis Membrane: Osmosis is the flow of water through a semi-permeable membrane from the low concentration side to the high concentration side. If a high-pressure pump is used to provide a high-concentration solution with a pressure greater than the osmotic pressure difference, water molecules will be forced to pass through the semi-permeable membrane to the low-concentration side. This step is called reverse osmosis. Reverse osmosis can filter out 90%-99% of most pollutants. Because of its superior purification efficiency, reverse osmosis is a very effective technology for water purification systems. Because reverse osmosis removes most of the contaminants, it is often used as a pretreatment method, which can significantly extend the life of the deionization column. Reverse osmosis treated water is high quality pre-purified water suitable for routine use in many laboratories. The reverse osmosis membrane made in the United States can effectively remove various salt ions, organic matter, bacteria, and viruses in the water, and the total salt removal rate can reach more than 99%, and can remove organic matter with a molecular weight greater than 300dalton;

Purification column: US ultra-pure water special ion exchange resin and special flow path design, high ultra-purification efficiency, can effectively remove trace ionic substances in water.

The operation control of the machine adopts intelligent microcomputer control, touch the button, and has the operation status display, and the water quality online monitoring, fully realizes the man-machine dialogue.

造水状态

5.3  启动

打开自来水阀门后,打开机器背部的电源开关,按下控制面板上启动键,“系统状态”灯亮;设备开始进入开机自动冲洗状态,“RO冲洗”灯闪烁;约3分钟后,如果纯水未满水,会自动切换到造水状态,“造水中”灯亮;反之,则“纯水备用”灯亮。

5.4  冲洗

5.4.1  上电自动冲洗。当按下启动按键后自动自行上电冲洗功能,可由RO冲洗键中断上电自动冲洗进入RO人工冲洗。

5.4.2  造水后自动冲洗。当造水水满后,自动执行造水后冲洗,可由RO冲洗键中断造水后自动冲洗进入RO人工冲洗。

5.4.3  定时冲洗。当累计造水超过两小时后,自动执行2分钟定时自动冲洗,定时自动冲洗未完成时可由RO人工冲洗中断进入RO人工冲洗,但不能立即消除系统的定时冲洗记忆,当中断RO人工冲洗后还会执行定时冲洗。但当执行上电冲洗或RO人工冲洗时间超过2分钟后,可消除系统中定时冲洗的记忆。

5.4.4   RO人工冲洗。当按下RO键,执行人工冲洗,再次按下RO按键中断RO人工冲洗,否则5分钟后自动结束冲洗。

上电冲洗、定时冲洗、造水后冲洗属于系统自动执行的冲洗动作,当执行自动冲洗时,冲洗指示灯闪烁指示,当自行RO人工冲洗时,冲洗指示灯常亮。

5.5  造水

当系统检测到水箱水位在中液位下时,启动造水,当水位到达高液位时,停止造水。但当虽然检测到中液位无水而高液位水满时(液位开关有故障),或检测到进水压力低时,则不会执行造水动作,如果正在执行造水动作也会立即中断,系统会进入报警状态(见报警)。

5.6  取水

当低液位有水时,按下三级取水按键,执行三级取水功能,再次按下相应按键,停止相应动作。

当电路板后面的K2处于断开状态时,系统工作于定时间取水模式。该模式下,如用户设定的定时间值不为0,取水动作执行到设定的时间后自动停止,如用户设定的定时间值为0(显示―――),则关闭定时功能。

5.7  压力控制

当选压力控制模式时,显示窗口显示压力桶压力。当水箱低液位有水10分钟后或当中液位有水时,系统判断压力值,当压力值低于设定的压力低限时,系统输出控制信号驱动外部故态继电器,反之,当压力高于等于设定的压力高限时,系统关闭该驱动输出。

5.8   报警及保护

5.8.1  当系统检测到进水压力低时,不能执行或中断执行的造水动作,系统发出1s-1s间隔的声光报警。按任意键或一分钟后自动消除报警声音。

5.8.2  当系统检测到中液位无水高液位水满时,不能执行或中断执行的造水动作,系统发出0.5s-0.5s间隔的声光报警。按任意键或一分钟后自动消除报警声音。

当系统检测到低液位无水时,不能执行取水、循环或中断当前的取水、循环动作,系统发出0.3s-2s间隔的声光报警。按任意键或一分钟后自动消除报警声音。

5.9  水质调节

当电导表显示电导值远大于5μs/cm时,需调小机箱内部“纯水手动针阀”,当“纯水手动针阀”调节至最小后,电导值仍远大于5μs/cm,此时需更换纯化柱mp3,以满足老化机进水水质要求;当电导表显示电导值小于5μs/cm时,需调大机箱内部“纯水调节阀”。

6  耗材更换操作步骤 

先关闭自来水进水阀,当低压开关报警后关闭电源开关,这样可减少滤芯中的余水量,便于耗材更换,再打开机箱两侧活动门,可利用简单工具进行设备的更换:

 6.1  一级预处理器滤芯:用皮带扳手套住标有一级预处理器滤芯(PP滤芯)的筒体逆时针旋转,慢慢将一级预处理器滤芯筒体拧松,取下筒体,将内部的滤芯取出,清洗一下筒体(清洗时请注意筒体内的黑色橡胶圈不要弄掉),将新一级预处理器滤芯(PP滤芯)装回筒体,注意PP滤芯的中心孔要与筒体的中心孔对齐,然后把筒体装到固定的端盖接口上,用皮带扳手套住筒体,顺时针旋转拧紧,参考示意图一、图二。

6.2  二级、四级预处理器滤芯:二级(活性炭滤芯)、四级(精滤滤芯)预处理器滤芯的更换与一级预处理器滤芯更换一样(请注意活性碳上的黑色橡胶垫圈不要弄掉)。

6.3  Molp mp3号纯化柱的更换:松开固定纯化柱的抱箍和纯化柱两端的PE管快插接头,换上新的纯化柱即可。更换时注意PE管快插接口要插紧,并用蓝色卡子卡紧。

6.4  反渗透膜的更换:了解膜的三个接口的进出水方向,特别注意纯水口与废水口不要混淆。然后松开固定膜的抱箍或单夹,接上新到的反渗透膜,连接好各对应接口管子,并用蓝色卡子卡紧。

注意:

①、按顺序安装,对号入座。

②、各个部件要拧紧,卡到位,否则设备在制水过程中容易漏水。

③、安装完毕后,接通电源进行冲洗和运行,如果发现漏水,请及时紧固接头,确认不漏水和水质达到标准方可使用。
