The elevator's new standard should not be too tide
The elevator's new standard should not be too tide
2020-01-10
New elevator standard implemented yesterday The operating place must not be too tide The reporter of Yangcheng Evening News reporter Chen Qiang reported: From yesterday, the new National Standard for "Elevator Technical Conditions" came into effect, which stipulated that the elevator operation location should not be too humid. If condensation may occur on electrical equipment, measures should be taken to dehumidify it; The opening and closing time of the automatic elevator of the middle point should not exceed 3.2 seconds. According to the new standard, when the maximum temperature of the elevator operating place is 40 ℃, the relative humidity of the air must not exceed 50%, and the relative humidity can be higher at lower temperatures; the monthly average minimum temperature of the wettest month does not exceed + 25 ℃ , The monthly average maximum relative humidity of the month does not exceed 90%. For such a humidity standard, for Guangzhou, which returns to Nantian every year, will the elevator stop on wet days? The reporter learned from the Municipal Quality Supervision Bureau that current elevators have moisture-proof measures, such as: reducing humidity in the machine room by turning on a dehumidifier, air conditioner, and high-power fans in the elevator machine room; the electrical circuits in the shaft are mainly enhanced by maintenance , Manually clean up the moisture around electrical lines, and so on. According to the municipal quality supervision department, the new standard is only applicable to passenger elevators and cargo elevators, not to hydraulic elevators and sundries elevators.
The new national standard will be implemented from March 1st: the elevator opens and closes the door within 3.2 seconds

According to the new National Standard for Elevator Technical Conditions, which will be implemented on March 1, the door opening and closing time for passenger elevators should not exceed 3.2 seconds. The new standard also strictly regulates elevator noise and other aspects. At present, the provincial quality supervision department is organizing elevator production and installation enterprises to improve the corresponding equipment. The new "National Standard" stipulates that if the passenger elevator is a mid-point automatic door, the door opening and closing time should not exceed 3.2 seconds; if it is a side opening automatic door, the door opening and closing time should not exceed 3.7 seconds. At the same time, the new “National Standard” strictly distinguishes elevator noise. According to regulations, the maximum noise value of a passenger elevator with a rated speed of 2.5 meters per second or less should not exceed 55 decibels during operation; a passenger elevator with a rated speed between 2.5 and 6 meters per second, during operation The maximum internal noise value should not exceed 60 dB; during the door opening and closing process of all passenger elevators, the maximum noise value should not exceed 65 dB. The new standard specifically proposes that the elevator car should be equipped with an alarm device that is easy for passengers to identify and reach.
