[0002] Float type liquid level switch in thermal power plant: It is the main equipment used in thermal power plant to measure the high and low liquid level alarm of pressure vessels. Figure 3 When the liquid level in the container rises, due to the buoyancy, the float connecting rod rises with the liquid level, and then the magnet on the high liquid level switch and the magnetic metal block on the connecting rod are attracted, and the switch action triggers a high alarm; when the liquid level in the container drops, the float connecting rod drops with the liquid level, and then the magnet on the low liquid level switch and the magnetic metal block on the connecting rod stop attracting, and the switch action triggers a low alarm.

[0003] Due to the presence of some impurities in the soda system pipeline, after the equipment has been running for a long time, the float in the liquid level switch sampling pipeline becomes stuck, causing the liquid level switch to malfunction and fail to operate accurately.

This not only increases the workload of the operators, but also poses a risk of high-temperature burns and falls from heights.
