Sampling cooler for a sample cooler principle within the boiler room or laboratory sampling soda plant cooling, boiler and heat water in the system mostly higher temperatures, and high water temperature is not easy to sample, not easy determination of the sampling should be cooling Therefore, the introduction of sampling points should sample sample cooler for cooling, the general requirements to ensure the flow when 500-700mL / min, the sample can be cooled to below 30-40 degrees taken to meet the People's Republic of China power industry DL / T 457-91 standard. Sampling conduit are made of stainless steel, carbon steel tube can not or yellow brass, in order to avoid sample is conduit metallic corrosion product in contaminated during sampling. Sample cooler is suitable for high temperature liquids and gases, and other media sampling, with a compact structure, high heat transfer efficiency, easy to clean, long life and other advantages. 3 ordering 1: sampling tube of stainless steel, carbon steel shell. 2: Sample cooling general election diameter 10,12,14,16,18mm (also specified by the user) interface and an optional welding flange, cooling water connection for DN25, external threads. 3: General Selection often: QYL-159 / 0.32, QYL-219 / 0.40 and QYL-273 / 0.54. 4: Is it necessary modular (ie, whether to stand, sinks, valves, etc.). 4 types of a sample. Sampling boiler water boiler water sample taken from a continuous outfall Drum general, the longer lead to cooler. Sampling points should be as close to the outfall Drum exit leads and try to install a sewage valve before the first lead after the drum. 2. Water Sampling Water sampling points generally located after the feed pump, high pressure before the economizer pipe, it should be in a vertical pipeline connected to a small tube pipes, water samples thus lead to sampling cooler. Water sampling tube should be located in the water after dosing sufficient mixing position. 3. Condensate sampling condensate sampling points generally located at the outlet of the condensate pump condensate water pipeline, condensate pump should not be installed in the entrance, due to the entrance of the condensate pump pressure below atmospheric pressure. 4. Hydrophobic hydrophobic general sampling in sparse sampling tank. Sampling points are usually located at a distance of about 300mm at the bottom of hydrophobic. 5 steam sample by sample cooler, it condenses into water. Steam in the steam flow sampler generally 20-30kg / h. The sample outlet tube and cooler requirements, and the same water sample.
