As an integral part of the power plant boiler system, the electric contact press-in electrode DJY2212-87 is mainly used to monitor the water level in the boiler, and its accuracy directly affects the safety and efficiency of the entire system. However, during long-term use, due to the influence of factors such as water quality, temperature and pressure, these electrodes are prone to scaling, resulting in a decrease in conductivity, which in turn affects the measurement accuracy and even causes safety hazards. Therefore, it is of great significance to reasonably formulate and implement the cleaning cycle to ensure the normal operation of the equipment.

1. Scaling mechanism and its impact on electrode performance

Scaling is mainly formed by the precipitation of minerals dissolved in water (such as calcium, magnesium, etc.) under high temperature and high pressure. With the increase of use time, these precipitates gradually accumulate on the surface of the water level gauge electrode DJY2212-87, hindering the direct contact between the electrode and water and reducing the conductivity. In addition, the presence of certain chemicals may also accelerate the scaling process or change the nature of the sediment, making cleaning more difficult. When the conductivity of the electrode decreases significantly, it may not only lead to inaccurate water level readings, but also cause unnecessary shutdown inspections due to misjudgment, increasing operating costs.

2. Analysis of factors affecting scaling rate

To determine a reasonable cleaning cycle, we first need to understand which factors affect the scaling rate. The main points include the following:

• • Water quality: including hardness, pH value, and whether there are corrosive or precipitation-promoting chemical components.
• • Operating conditions: such as working temperature, pressure level, etc. Generally, higher temperature and pressure will accelerate the scaling process.
• • Operation mode: Compared with intermittent operation, continuous operation is more likely to form a stable scaling layer.
• • Electrode DJY2212-87 material and structural design: Different materials have different anti-fouling capabilities, and reasonable structural design can also help reduce scaling.

3. Design method of cleaning cycle

Based on the above influencing factors, the following steps can be taken to design the cleaning cycle:

• • Preliminary evaluation: Conduct a preliminary evaluation based on historical data and field conditions to determine a rough cleaning interval. For example, in the case of poor water quality and harsh working environment, the initial setting is to clean once every three months.
• • Dynamic adjustment: After the initial setting is implemented, the working status of the electric contact electrode DJY2212-87 is regularly monitored, such as observing the trend of the output signal, to determine whether the cleaning interval needs to be shortened or extended. If the signal fluctuates frequently, it means that the current cycle is too long; otherwise, it can be appropriately extended.
• • Preventive maintenance plan: Combined with actual operating experience, a complete preventive maintenance plan is formulated, covering various measures from daily inspections to regular professional cleaning. This not only helps to detect potential problems in a timely manner, but also effectively reduces the risk of sudden failures.

4. Cleaning process optimization

It is equally important to choose a suitable cleaning method. Common cleaning methods include physical scraping, chemical cleaning, and ultrasonic cleaning. Each method has its advantages and disadvantages and needs to be flexibly selected according to the specific situation. For example, for mild scaling, simple physical cleaning can meet the requirements; for stubborn stains, chemical reagents or ultrasonic technology may be required. At the same time, care should be taken to avoid excessive cleaning that causes electrode damage.

A power plant once faced serious scaling problems during the use of DJY2212-87 electrodes, which seriously affected the safe operation of the boiler. After a series of explorations and practices, the plant finally established an effective cleaning solution: on the one hand, the cleaning frequency is adjusted in time according to the water quality test results and seasonal changes; on the other hand, an advanced online monitoring system is introduced to track the electrode status in real time to ensure that any abnormality can be responded to quickly. This move not only greatly improves the reliability of the equipment, but also significantly reduces maintenance costs.

For the scaling problem of the boiler water level gauge electrode DJY2212-87, by deeply understanding the scaling mechanism, comprehensively analyzing the influencing factors, and scientifically planning the cleaning cycle based on this, the service life and measurement accuracy of the electrode can be effectively improved, and the safe and stable operation of the boiler system can be guaranteed.
