Why are elevators afraid of water and dirt?


    Some people wonder: The elevator structure is made of metal, why is it afraid of water? We often find people dumping dirty water or other liquids (such as drinks) in the elevator car, and some people sweep the water into the shaft when cleaning the corridor. They thought the shaft was just a hollow. They don’t know that there are many mechanical parts and electrical components installed under the car top, car bottom, and landing door sill. The water or other liquids flow into the car top, car bottom or landing door mechanism, not to mention causing corrosion of these components, and more seriously, it will cause the failure of the electrical components installed in these places. For example, when there are typhoons in many cities in the south, many elevators are "paralyzed" because water enters the pit, causing the electrical appliances in the pit to fail.
 
    There are many wires and circuit boards arranged on the elevator car and landing door. Water intrusion will also cause the insulation of electrical appliances and wires to decrease, causing leakage. It is very dangerous for such an elevator to be put into operation and will cause serious injuries to the passengers. Electric shock accident. Electric leakage will also cause more serious damage to the elevator control system. For example, causing the computer board to burn out. Therefore, if water enters or gets wet in the elevator, the power supply to the elevator must be stopped, the water should be cleaned and dried as soon as possible, and professional maintenance personnel should be asked to test the circuit before it can be put into use again.
 
    Why are elevators afraid of garbage?
 
    On the surface, "garbage" is just a hygiene issue. Some people usually develop the habit of not paying attention to hygiene and are used to littering garbage and cigarette butts everywhere. Therefore, domestic waste such as peels, cigarette butts, and leftover food are often found in the elevator car. Some passenger elevators are also used to transport construction materials. As a result, there is a lot of construction waste in the car, such as broken bricks, cement dust, etc. This garbage is not only a sanitation problem for the elevator, it may cause the elevator to "go on strike" and stop running. Many people who use elevators may not be aware of this, but many elevator maintenance personnel feel it deeply. They often encounter some maintenance elevators that malfunction and cannot operate. When the maintenance personnel arrive at the scene, they discover the cause of the failure. Simply due to "trash".
 
    The elevator will automatically detect whether the elevator door is closed before starting. If the door is not completely closed, even if it is just a little bit close, the elevator will not start. So a cigarette butt or a pebble can stop the elevator from running. Some elevator door anti-collision devices use light curtains, that is, infrared devices. Once the infrared rays are blocked, the elevator will not close the door and stop running. A small piece of peel or chewing gum, or even cement dust can block the infrared rays.
 
    What's more, some people sweep the garbage on the corridor into the elevator shaft. They don't realize that the elevator is an electromechanical device. Just like the air conditioner and TV at home, too much dust will affect the work. Similarly, there are many electrical equipment going up and down the elevator. The switch will also have poor contact due to dirt, and such an elevator will have constant problems.
 
    Therefore, if you want the elevator to operate well, you must first operate in a good environment and pay attention to hygiene. "Protect the elevator and facilitate yourself."

For those who are struggling but don’t know how to start in elevator sales

Once upon a time, there were two hungry people who received a gift from an elder: a fishing rod and a basket of fresh and huge fish. One of them asked for a basket of fish, and the other asked for a fishing rod, so they parted ways. The person who got the fish used dry wood to set up a bonfire and cooked the fish on the spot. He wolfed it down, and before he could taste the aroma of the fresh fish meat, he ate up all the fish and soup in a blink of an eye. Soon, he was Starved to death next to an empty fish basket.     The other man carried the fishing rod and continued to suffer from hunger, walking hard step by step towards the seaside. But when he saw the blue ocean not far away, the last bit of strength in his body was exhausted. He could only pass away helplessly with endless regrets.
