With the popularization of new energy vehicles, the demand for charging piles is increasing. However, in the actual use process, various faults of charging piles are also emerging one after another. Among them, the problem of protection door lock of charging pile fault diagnosis equipment is particularly prominent. This paper will discuss the importance, common problems and solutions of the protection door lock of charging pile fault diagnosis equipment.
I. Importance
The main function of the protective door lock of the charging pile fault diagnosis equipment is to protect the internal electrical components from the external environment and play an isolation role in the event of an accident. If there is a problem with this component, it may affect the safety and stability of the whole charging pile, and even lead to the user's failure to use the charging pile normally or a safety accident. Therefore, it is very important for charging pile manufacturers and maintenance personnel to understand and master how to correctly install, check and maintain the protective door lock of charging pile fault diagnosis equipment.
Second, common problems and their solutions
1. The door lock is damaged: This is the most common problem. Usually, the damage of door locks may be caused by the wear of mechanical parts. In view of this situation, we need to replace the new door lock assembly in time to ensure its normal work.
2. Deformation of protective door: If the protective door itself has obvious deformation, it needs to be corrected before considering whether it needs to be replaced with a new one. Of course, in some extreme conditions (such as strong impact), it may also directly lead to serious damage to the protective door beyond repair; At this time, we can only choose to replace the whole protective door.
3. The sealing strip is aging and falling off: the function of the sealing strip is to isolate external dust and water vapor from entering the internal space in the closed state. Once problems (such as cracking and degumming) are found in this part, they should be repaired as soon as possible so as not to affect the overall protection effect;
4. The lock core is stuck and fails: in this case, you need to try to clean the impurities in the bolt hole and lubricate it again; If there is no obvious improvement, disassemble it further to check whether there are any problems such as foreign objects blocking the action path or spring failure, etc.; Finally, according to the actual situation, judge whether it is necessary to replace parts to complete the repair task.
Third, preventive measures
In order to avoid the above-mentioned failures, the following aspects should be strengthened in daily management:
Regularly check whether the state and functional performance of all related parts meet the standard requirements;
Pay special attention to cleaning up accumulated water and sundries before and after bad weather conditions to prevent corrosion and damage;
Enhance the staff's safety awareness and technical ability training level so as to find out the problems in time and take effective measures to eliminate them;
Reasonable planning maintenance cycle to avoid long-term negligence leading to irreversible accumulation of hidden dangers, etc ...
To sum up, as an important bridge connecting the external operation interface and the internal circuit system, the door lock of the charging pile fault diagnosis equipment plays a vital role in ensuring the charging quality of vehicles and the safety of people and property. We should fully realize that this link has far-reaching significance for the operation efficiency and reliability of the whole facility, and take active measures from various angles to reduce the failure rate and improve the service quality!
