In thermal power plants, the drum expansion indicator HPSQ150-150*150 is a vital device used to monitor the expansion of thick-walled pressure vessels such as drums during ignition and pressure boosting. It can monitor the expansion state of evaporation equipment in real time, and promptly detect deformation caused by improper ignition and pressure boosting or poor installation and maintenance, thereby preventing safety hazards such as cracks and leaks in evaporation equipment due to uneven expansion. However, during long-term use, factors such as dust and dirt may have a negative impact on the measurement accuracy of the drum expansion indicator. Today we will explore how to take effective strategies to avoid measurement errors caused by these factors.

1. Working principle and importance of drum expansion indicator HPSQ150-150*150

By measuring the expansion of the drum, the drum expansion indicator HPSQ150-150*150 provides key data to operators so that they can adjust operating parameters in time to ensure the safe operation of the equipment. This device is usually installed at a specific position of the steam drum. It senses the tiny deformation of the steam drum through internal mechanical or electronic sensors and converts it into a readable indication or signal.

In a thermal power plant, the expansion of the steam drum is directly related to the stability and safety of the entire steam system. If the steam drum cracks or leaks due to uneven expansion, it will cause the steam system to fail and may even cause serious accidents. Therefore, the accuracy and reliability of the steam drum expansion indicator are crucial.

However, during long-term use, the steam drum expansion indicator may be affected by many factors, among which dust and dirt are one of the most common problems. These contaminants may adhere to the sensor surface of the indicator, preventing it from normally sensing the expansion of the steam drum.

2. Dust and scale prevention strategies

In order to avoid the influence of dust and dirt on the measurement accuracy of the steam drum expansion indicator, a series of dust and scale prevention strategies need to be adopted. These strategies include regular cleaning, the use of protective devices, the optimization of the installation environment, and the use of advanced sensor technology.

Regular cleaning:

Develop a detailed cleaning plan, including cleaning cycles, cleaning methods, and required tools.

Use special cleaning agents or solvents to ensure that dust and dirt on the sensor surface are thoroughly removed.

During the cleaning process, be careful to avoid mechanical damage or corrosion to the sensor.

After cleaning, wipe the sensor surface with a dry, lint-free cloth to ensure that there is no residue.

Use protective devices:

Install a protective cover or dust screen in the indicator installation area to effectively block the entry of dust and dirt.

The protective device should have good sealing performance to ensure that dust and dirt cannot penetrate.

Regularly check the integrity of the protective device and replace damaged or aged parts in time.

Optimize the installation environment:

Choose a suitable installation location to avoid direct exposure of the indicator to harsh environments.

Set up appropriate ventilation facilities around the indicator to reduce temperature and humidity and reduce the deposition of dirt.

Clean and maintain the installation environment regularly to ensure that the environment is clean and dry.

Establish a monitoring and feedback mechanism:

Establish a real-time monitoring system for the drum expansion indicator to record and analyze the measurement data in a timely manner.

Set a reasonable alarm threshold to automatically issue an alarm when the measurement data deviates from the normal range.

Establish a feedback mechanism to encourage operators and maintenance personnel to report abnormal conditions of the indicator in a timely manner so that timely measures can be taken to deal with them.
