概述
Zlsc water quality intelligent control device is specially used for water treatment of central air conditioning and industrial circulating water system. The system adopts advanced industrial automatic water treatment technology and is designed according to the operation characteristics of the system, It has a good water quality monitoring function. It integrates the functions of online water quality detection, automatic real-time addition of chemicals and automatic sewage discharge, gives full play to the scale inhibition, corrosion inhibition, sterilization and algaecide killing effects of chemicals, provides comprehensive, effective and economic protection for the central air conditioning system, and thoroughly solves the problems of scaling, corrosion, bacteria and algae breeding and slime deposition in the central air conditioning water system. The whole automatic dosing device adopts a special PLC central controller as the core, and is configured with 1-3 dosing buckets, agitators, liquid level devices, metering pumps, detection probes, solenoid valves and other external signal output equipment. Taking the conductivity value and concentration multiple of circulating water as the test object, the measured value is used to measure the quality of water quality, send out the signals of dosing and blowdown, and implement the dosing and blowdown through external equipment, so as to realize the automatic operation of the system, and maintain a certain concentration multiple of water while realizing the sterilization, alga killing, scale inhibition and corrosion inhibition. The main machine and main parts can be imported or domestic products, which can be formulated at will according to the needs of users. |

| The working principle of zlsc is shown in the figure. Small pipes are connected to the device from the main water supply and return pipes of the system to form a cycle management. Through high-precision online water quality detection equipment, the device tracks the change of circulating water quality, and controls the dosing pump to automatically and quantitatively add chemicals to the water in real time, so as to achieve the corresponding water treatment effect. At the same time, the device detects the concentration multiple of circulating cooling water, realizes quantitative automatic blowdown, and ensures that the concentration multiple of cooling water is within the range of economic rationality, so as to give full play to the role of chemicals and save the blowdown water. Zlsc, as a chemical water treatment equipment, has obvious treatment effect, avoiding the randomness of dosing time, dosing amount and sewage discharge during manual treatment. It can truly realize online sampling, automatic detection, automatic control, quantitative dosing, quantitative sewage discharge, real-time monitoring and other functions, accurately and effectively control dosing amount and sewage discharge amount, and maintain reasonable system water quality. | |

Zlsc has powerful control function and high intelligence.
1. Human machine interface: touch the key, Chinese LCD display, simple operation, function data display at a glance.
2. On line monitoring: system water circulation through the device, on-line sampling detection and analysis, real-time monitoring of water quality.
3. Intelligent operation: after setting parameters once, the equipment will operate automatically and intelligently. The central controller controls the dosing pump to add different chemicals in real time. According to the quality of circulating cooling water, the concentration multiple of water shall be controlled according to the set requirements, and the blowdown shall be controlled automatically without manual operation.
4. Manual control: at the initial stage of operation, in order to adjust the water quality as soon as possible, it can be switched to manual control mode for operation. /
5. Lack of medicine alarm: when the medicine in the device will be used up, it will automatically give an audible and visual alarm to prompt the dosing.
6. Record query: display the operation status of dosing pump, query the current added flow and current blowdown flow of various chemicals, and query the cumulative added amount and total blowdown of various chemicals.
7. System linkage: linkage with the central air conditioning system to avoid unnecessary operation, automatic start and stop, and no manual on-site operation.
8. Coupon test: zlsc is designed with test coupon, which can directly observe the status of test coupon in circulating water through pressure resistant plexiglass tube and indirectly infer the status of the system.
9. Sampling interface: the sampling valve is convenient for sampling the water quality of the system for detection and analysis, so as to prepare more suitable reagents.
10. Password protection: after setting password parameters, non management personnel can only view relevant data and cannot change parameter settings.
1. Zlsc adopts the most advanced industrial water treatment technology, complete functions can fully meet the needs of central air conditioning water quality treatment, and effectively monitors the chilled water circulation system and cooling water circulation system, with remarkable results. 2. Intuitive human-computer interface, touch key, Chinese LCD display, function data display at a glance. 3. The device adopts integrated design, sampling and dosing are automatically completed in the control cabinet, and the installation is simple and fast. 4. Track the water quality online and add the corresponding water treatment chemicals in real time, so as to realize the scale inhibition, corrosion inhibition, sterilization and algaecide killing effect, and ensure the efficient, energy-saving and stable operation of the system. 5. Linkage with central air conditioning system, fully automatic operation, only inspection and observation, greatly reducing the labor workload. 6. Zlsc adopts imported high-precision detection, analysis and control device and high-precision dosing metering pump to ensure the accuracy and reliability of dosing. 7. In case of drug shortage, the equipment will send out sound and light dual alarm, and prompt to add drugs. 8. The password protection function enables the management personnel not to worry about the original set parameters being changed, so as to maintain the normal operation of the system. | |
