1. When passengers are in the elevator, they must consciously queue up in order and avoid “fighting for fear†and overweight crowding.
2. When the passengers are on the elevator, they must check whether the elevator car is on the ground. Do not enter the elevator blindly to prevent unexpected accidents where the landing door is open and the car is not in this floor and falls into the hoistway accident.
3. When passengers enter the car, they should not use the body to prevent the elevator from closing the door or back against the security touch panel. It is also forbidden to forcibly move the closed elevator door.
4. After passengers enter the car, they must press the operation button correctly, and they must not disassemble other facilities to prevent man-made accidents.
5. When a passenger encounters a power outage or a fault occurs in the elevator car, be patient and wait for the staff to come forward. Do not panic and forcefully open the door.
6, take the elevator to follow the social morality, avoid slapstick play, spitting, litter and paper debris and other debris.
7. It is forbidden to take the elevator when there is a fire or an earthquake and when the elevator fails.
Finally, I added: No matter how urgent the time is, we must remember safety first, life only once, it is so short, and how worthy of our cherishing and nostalgia.
Mechanical Diaphragm Dosing Pump
Mechanical diaphragm dosing pump, is characterized by the mechanically driven diaphragms which have replaced the previous structure type,it's an easy operation dosing pump. Which means: the working chamber of the pump liquid end is caused from the diaphragm, the diaphragm periodic motion produces the elastic deformation, throught this deformation the diaphagm will be reciprocating motion and reach the pump quantitative dosing, the accuracy of this dosing will be + 1%. The mechanical diaphragm is for precise and accurate metering control, operation remains reliable even when the main voltage fluctuations, the character of hermetically sealed and resistant materials allow diaphragm dosing pumps to convey aggressive media with ease, which also make it convenience to used in chemical and petrochemical, pharmaceutical, cosmetic and food production industry. then the adjustment of the stroke length allows the operator to make accuracy modulation. However, there are different control types which make easy process integration.
