Elevator afraid of the fear of dirty water
We also often find that someone dumped dirty water or other liquids (such as beverages) in the elevator car, and some people clean the corridor when the water to the well within the sweep. They thought the well was empty. They do not know that there are many mechanical and electrical components installed under the top of the car, at the bottom of the car, and below the floor sill. These water or other liquids flow into the car top, the car bottom, or into the landing door mechanism, not to mention causing corrosion of these components, and, more seriously, the electrical components installed in those places. For example, many cities in the south scraped the typhoon, many elevators because the bottom of the pit water, resulting in electrical failure of the pit, so the elevator "paralyzed."In the elevator car and the floor is also arranged on the door a lot of wires and circuit boards, water will cause electrical and electrical insulation to reduce leakage occurs, so the elevator is put into operation is very dangerous, will cause the occupants of the Electric shock accident. Leakage can also cause more serious damage to the elevator control system. For example, causing the computer board burned. So if the elevator water or water wet, etc., we must suspend the elevator power supply, as soon as possible to clean up the water, dry, professional service personnel to test the circuit before put into use.
Why is the elevator afraid of garbage?
"Garbage" on the surface just a health problem, there are some people usually do not pay attention to the habit of health, habit of littering, cigarette butts. So often found in the elevator car with peel, cigarette butts, leftover food and other household waste. There are also passenger lifts used to transport building materials, as a result of which there are many construction waste in the car, such as broken bricks, cement dust and so on. These rubbish are not only hygienic to the elevator, it may cause the elevator "strike" to stop the movement. Many elevator elevators may not be aware of this, but many elevator maintenance staff on the deep feelings, they often encounter some of the maintenance of elevator failure can not run, and maintenance personnel arrived at the scene and found that the cause of failure Just because of "junk".
Elevator before the start of the door to automatically detect whether the lift is good, if the door is not completely closed, even if only a little, the elevator will not start. So a cigarette butt, a small stone can let the elevator stop does not run. Some of the elevator door anti-collision device is the use of light curtain, the infrared device, once the infrared is blocked, the elevator does not close the door to stop running, a small piece of peel or gum, or even dust can block the infrared cement.
What is more, some people to the corridor of the trash to the elevator shaft in the sweep, they do not realize that the elevator is an electromechanical equipment, like home air conditioning, television dust will affect the work of the same, many up and down the elevator electrical The switch will be dirty because of bad contact, so the elevator will be problems continue.
So in order to run the elevator is good, first of all have to run the environment is good, pay attention to health. "Protection of the elevator, to facilitate their own."
