  • Water Quality Tele-Monitering System (W-TMS)
  • water quality TMS maintenance: planning for maintenance and check to keep function of measurement equipment normal condition
  • The purpose of Maintenance
    1) Operate stably the continuous water monitoring equipment for long period
    2) Minimize chronometry of measurement equipment
    3) Obtain reliable measure
  • Best prerequisite for maintenance
    1) Engineering personnel- secure more than two people at short distance
        ① Engineering personnel for water quality maintenance
        ② Engineering personnel for the relative accuracy test
        ③ The personnel exclusively responsible for measuring instrument
             - Three Maintenance department, all of their members have the related certificate
             - Management for its rapid support, the advantage as local company
    2) Equipment and facility- secure parts in proper numbers
    3) Document management – documentation and manualization of its maintenance task
        ① Operating manuals by different equipments
        ② Correcting manual
        ③ Manual for periodic inspection




 
  • Planning Maintenance
    1) Establishment of repair, interval of inspection and method by maintenance procedure
    2) Setting Correction frequency and establishment of Overhaul method
    3) Proper management and exchange method of deteriorated parts
  • Maintenance procedure
    1) Procedure on Maintenance planning
        Yearly plan: interval of routine inspection, securing and use plan for correction period, consumable and reagent
        ② Monthly plan: planning daily inspection interval and replacement time of consumable and reagent
        ③ Management through flow chart of Daily and emergency inspection
    2) Procedure for Maintenance and inspection- inspection manual through daily, regular and emergency inspection, overhaul, correction and etc
    3) procedure for documentation management
        ① Maintenance record for automatic water quality measuring instrument- name of model, approval on model number, type approval number, name of manufacturer, number of instrument, date of production, measuring principle and measurement method, measurement range, type and requirement of power, installation date, standard for replacement parts and consumables, maintenance for replacement records of consumables and parts
        ② Relative accuracy record- result of analysis, relative accuracy
        ③ Consumables record- maintenance for consumables and reagent use
        ④ Record on operation management of measuring instrument – management of measuring instrument by checklist
Management purpose interval of inspection details
Daily inspection(routine inspection) maintenance of normal operation once per week

1. Check operation condition of measuring instrument

2. check consumables

3. Cleaning and replacement of simple parts
Regular inspection(close examination) maintenance of its performance, Trouble precaution more than once per month

1. Adjustment of zero point, controlling span

2. Check consumables

3. Check channel section

4. Check detector
Emergency immediate action on emergency on occurrence of trouble

1. 1. Looking for trouble and simple repair

2. Finding the cause and repair
Overhaul repair and replacement of its deteriorated parts once per year

1. Disassembling and cleaning measuring instruement

2. Replacement and repair of parts

3. reassembly
  • Maintenance(daily inspection)
  • Maintenance(close examination)
