一．    设备简介

One Equipment introduction

电子化工行业中的超纯水设备主要应用于电池行溶剂用水、化学分析、化工材料、产品清洗、物质的分离、浓缩、提纯，废物回收等场合，对于水质要求相对来说不是太高，纯水电导率从0.1uS/cm-20uS/cm就基本上能满足要求。 lehu乐虎水务在满足用户用水标准的基础上，在设备系统中水箱均设有液位控制系统、水泵均设有压力保护装置、在线水质检测控制仪表、电气采用PLC可编程控制器，真正做到了无人职守，同时在工艺选材上采用推荐和客户要求的方法，使设备与其它同类产品相比较，具有更高的性价比和设备可靠性。

Ultra pure water equipment in electronic chemical industry is mainly used in solvent water, chemical analysis, chemical materials, product cleaning, material separation, concentration, purification, waste recovery and other occasions. The requirements for water quality are not too high. The conductivity of pure water from 0.1us/cm to 20us / cm can basically meet the requirements. On the basis of meeting the user's water use standard, Hongjie water has installed liquid level control system in the water tank of the equipment system, pressure protection device in the water pump, on-line water quality detection and control instrument, and PLC programmable controller in the electrical system, so that no one is on duty. At the same time, it adopts the method of recommendation and customer requirements in the technical material selection, so that the equipment can be compared with other similar products, It has higher cost performance and equipment reliability.
