一． 设备简介

1、 Equipment introduction

       电池行业用超纯水包括蓄电池生产用纯水，锂电池生产用纯水，太阳能电池生产用纯水，蓄电池格板用纯水。电池中电解液的配备对纯水要求严格,通常要求水的电导率在0.1us/cm（电阻值在10兆欧姆）以上。 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 for battery industry includes pure water for battery production, pure water for lithium battery production, pure water for solar cell production and pure water for battery grid. The electrolyte in the battery is strictly required for pure water, and the conductivity of water is usually required to be above 0.1 US / cm (the resistance value is 10 megaohm).   On the basis of meeting the user's water use standard, Hongjie water has set up liquid level control system in the water tank of the equipment system, pressure protection device in the water pump, online 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, the method of recommendation and customer requirements is adopted in the process of material selection, so that the equipment is compared with other similar products, It has higher cost performance and equipment reliability.
