The annual May Day has arrived

The annual May Day has arrived During the May Day holiday, our will be closed for five days. This, also known as Day, has its origins in the labor movement and is celebrated in countries around the world. The commemorates the achievements and contributions of workers. The history of the May Day holiday dates back to the late 19th century when labor activists around the world began to organize movements advocating for better working conditions, fair wages, and reduced working hours. One significant event that led to the establishment of this holiday was the Haymarket affair, which took place in Chicago, United States, in 1886. The labor movement called for a general strike on May 1st to demand an eight-hour workday. Over time, May 1st became symbolic for workers' rights, and many countries adopted it as a public holiday. In China, the May Day holiday was formally recognized in 1949 and has since been observed nationwide. It provides an opportunity for people to take a break from work, spend time with their families, and engage in leisure activities. In our company, the decision to have a five-day break during the May Day holiday is to allow our employees to rest and recharge. It is also a gesture of appreciation for their hard work and dedication throughout the year. We believe that a well-rested workforce is more productive and motivated, and this holiday serves as a way to promote work-life balance. During the May Day holiday, our company encourages employees to enjoy their time off responsibly, engage in recreational activities, or use the time for personal pursuits. We hope that this break will provide our employees with the opportunity to rejuvenate and return to work with renewed energy and enthusiasm.

Filtre PL420 ne peut pas remplacer les filtres PL421
2019-06-21

Dans le passé, le PL420 était utilisé comme premier filtre primaire pour les poutres des réservoirs de carburant. Il n'y a pas de pression. La rampe commune est sous pression et le PL420 est sous pression négative.


Avant l'apparition de la pompe à pression électronique, la coupelle transparente est très sûre, la coupelle transparente n'est pas endommagée par la pression, mais avec l'avènement de la pompe à pression électronique, les deux filtres grossiers du moteur passent de la dépression à 4 pressions positives encore plus de pression. Le gobelet transparent à l'ancienne PL420 présente un risque de fuite d'huile.


Certains constructeurs ont remplacé le PL420 sur le moteur par le PL421 sans tasse. Cependant, certains constructeurs n’ont pas envisagé ce problème. Ils ont encore chargé le PL420. (Il y a maintenant Delong) il y a des risques de conception.


Il est recommandé d'utiliser le filtre PL421 pour les modèles équipés d'une pompe électronique.
