I. Brief Description of Carbonated Beverage Sampling Equipment
Water and steam sampling devices are used for thermal systems in power plants and secondary loop systems in nuclear power plants. They facilitate online chemical analysis, measurement, and network monitoring of water and steam quality. The instrument racks are centrally located to house various analytical instruments and allow for manual sampling. The devices protect against over-temperature, over-pressure, and flow interruption for the water samples entering the instruments. Additionally, a cooling water flow interruption protection system is set up to ensure the safe and reliable operation of the instruments.
Carbonated Water Sampling Device and Boiler Water Sampling Apparatus are used for sampling and cooling water for chemical testing in boiler rooms or power plants. The sampling cooler is used for heat exchange of liquids and gases at high temperatures. The water in boilers and thermal systems is usually at high temperatures, which is not convenient for sampling and testing. Therefore, cooling should be added during sampling, i.e., cooling the samples taken at the sampling point. When the cooler cools the samples, it is generally required to ensure that the flow rate is between 500-700 mL/min, and the samples can be cooled to below 30-40 degrees to meet the standard DL/T 457-91 of the People's Republic of China's power industry.
