The water vapor sampling device is used for on-line chemical analysis, measurement and network monitoring of water vapor quality in thermal power systems of thermal power plants and secondary circuit systems of nuclear power plants. The instrument rack is equipped with various types of analytical instruments and can be manually sampled. The over-temperature and over-current protection of the sample water entering the instrument is provided, and the cooling water cut-off protection system is set to ensure the safe and reliable operation of the instrument.
The soda water sampling device boiler water sampler is used for sampling and cooling of steam and water in the boiler room or power plant, and the sampling cooler is used for medium heat exchange of liquid and gas with higher temperature. The water in the boiler and the thermal system is high in temperature, and the high water temperature is not convenient for sampling and testing. Therefore, it should be cooled during sampling. That is, when the sample of the sampling point is introduced into the sampling cooler for cooling sampling, the general requirement is to ensure the flow rate is 500- At 700mL/min, the sample can be cooled to below 30-40 degrees to meet the standards of the People's Republic of China power industry DL/T 457-91.
Second, the characteristics of the soda sampling device:
1. The instrument frame adopts the front panel form, which is compact in structure and elegant in appearance.
2. The over-temperature and over-pressure protection device is used to protect valuable instruments.
3. The rod needle type pressure reducing valve is used to continuously adjust the pressure and flow in line.
4, using a constant temperature device for constant temperature, flow-through cooler, high cooling efficiency, to ensure that the temperature of the sample water is constant at 25 ± 1 °C.
5, using cold bending and welding process, to prevent leakage of the pipeline system.
6. There are channels inside the instrument panel for easy maintenance and repair.
7, using the sample water pre-cooling technology, can extend the life of high temperature and high pressure sewage valve.
8. High-pressure backwashing filter prevents the pressure reducing valve from being clogged and can be drained and self-flushed.
