Online water quality monitoring equipment maintenance content

Online water quality monitoring equipment is one of the important devices for analyzing water quality. Through it, it is possible to analyze whether the water quality is abnormal in real time. However, since the water quality in most environments is relatively poor, in order to avoid the degradation of the monitoring performance of the equipment after long-term use, it should be regularly monitored. To maintain it, let me tell you about the maintenance content of online water quality monitoring equipment. Maintenance content of online water quality monitoring equipment 1. Check the operating status of the equipment remotely every morning or afternoon to check whether the data transmission is normal. If there is any abnormality, go to the site for inspection in time. 2. Calibrate the zero point and span of the pH meter and online water quality monitoring equipment every 48 hours to ensure its stability. 3. On-site maintenance is required once a week. The main contents are: (1) Check the operating status and main parameters of each instrument and auxiliary equipment to judge whether it can operate normally. (2) Check the water supply and pump water intake, check whether the pipeline installation is normal, whether the cleaning device can operate normally, etc., and clean it in time if necessary. The water pump and filter screen need to be cleaned according to the actual situation. (3) Check whether the circuit system and communication system in the station building are normal. (4) If the equipment is measured by the electrode method, it is necessary to check whether the standard solution, electrode filling liquid, air pressure, etc. meet the testing requirements. (5) Check whether the standard solution and reagents of the instrument are within the effective use period, and replace the standard solution and reagents regularly according to requirements. (6) If the station uses gas cylinders, it is necessary to check whether the carrier gas path is sealed and whether the air pressure can meet the use requirements. (7) Observe the operation of the data acquisition device and check whether the connection is damaged. You can sample the data and check whether the data received by the analyzer and the joule host computer of the data acquisition device are consistent. In addition to regular maintenance, online water quality monitoring equipment also needs monthly maintenance and other preventive maintenance, as well as regular calibration and maintenance of equipment, so as to ensure long-term stable operation of online water quality monitoring equipment.
