Mechanical shutdown electromagnet DF22025 plays a vital role in the safe operation of steam turbines. In an emergency, the mechanical shutdown electromagnet can start quickly, cut off the supply of high-pressure security oil, and open the oil drain port to release the high-pressure security oil, quickly close the main steam valve and the regulating steam valve, cut off the steam inlet of the unit, and ensure that the steam turbine Able to stop operation safely and quickly.

To ensure the reliability and stability of the mechanical shutdown solenoid DF22025, regular maintenance and inspections are essential. The following are some key items for maintenance and inspection of solenoid during mechanical shutdown:

First, conduct a visual inspection to check whether the electromagnet housing is cracked or damaged, and whether the connecting wires are intact and not broken or loose. This is because damage to the casing or problems with the connecting wire may affect the normal operation of the electromagnet.

Secondly, conduct electrical inspection, measure whether the pull-in voltage and release voltage of the shutdown electromagnet DF22025 meet the regulations, and check whether the insulation resistance of the electromagnet is within the allowable range. These checks can help ensure that the solenoid’s electrical performance is normal.

Next, perform a mechanical operation check, manually operate the electromagnet, and check whether its attraction and release are normal. At the same time, check whether the hook of the emergency interrupting device releases smoothly and whether the connecting rod is stuck. These checks ensure the normal operation of mechanical parts.

Inspection of worn parts is also one of the important maintenance items. Check whether the seal of the electromagnet DF22025 is worn or damaged, and whether the connecting rod and support hook are worn, and replace it if necessary. At the same time, make sure that the environment around the electromagnet is clean and free of dust, moisture or other debris to prevent problems such as short circuits.

Regular maintenance and inspection of the mechanical shutdown electromagnet can ensure its reliability and stability, reduce the possibility of failure, and ensure the normal operation of the steam turbine and personnel safety.
