steam and water sampling and analysis system for power plant

The steam and water sampling system is mainly used for continuous sampling and testing of water vapor samples in thermal power plants and other high temperature and high pressure water vapor systems. It ensures the stable operation of thermal equipment and provides reliable samples for subsequent analysis through an accurate sampling process and a good temperature control system. This device plays an important role in ensuring the reliability of equipment operation and optimizing management, especially in ensuring the accuracy and stability of water vapor samples.

steam and water sampling and analysis system Structural components

1. Cooling and depressurizing frame: used for cooling and depressurizing the water vapor to ensure that the temperature and pressure of the sampled water vapor meet the standard requirements.
2. Manual sampling frame: Provide sampling interface for manual operation, which is convenient for staff to take samples.
3. Instrument panel rack (optional thermostat device): install and maintain relevant measuring instruments or temperature control equipment.

Working Principle

The steam and water sampling system adopts the principle of cooling down and then depressurizing to ensure that the sampled water vapor samples are collected at the appropriate temperature and pressure. By setting up the process of temperature and pressure reduction, it avoids heat loss or pressure loss of the sample during the collection process and ensures the representativeness and accuracy of the sample.

steam and water sampling and analysis system Equipment features

1. First cooling and then decompression: to ensure that the water vapor sample meets the sampling standards, to avoid changes in the sample due to excessively high temperature or pressure.
2. High-pressure valve: the imported high-pressure valve has a strong resistance to scouring, prolonging the service life.
3. Two-stage pressure protection: with two-stage pressure protection to ensure that the sample flow uniformity and system security.
4. Thermostat system: open thermostat system, can stably control the sample water temperature at 25 °C ± 1 °C, to ensure the stability of the sample.
5. Water filtration system: through the combination of coarse and fine filtration, to reduce the impact of impurities on the sampling process, maintenance is simple and convenient.
