Elevators are very, very common in our lives. Elevators need constant maintenance. As everyone knows, many people will ignore some precautions for elevator machine room maintenance. The elevator machine room is a place where maintenance personnel often stay, so everyone should pay more attention to the environment of the machine room. Next, I will introduce to you what needs to be paid attention to in the maintenance of the machine room environment of elevator maintenance knowledge?


1. No entry for idlers
The computer room should be managed by maintenance and repair personnel. Other non-professionals are not allowed to enter at will. The computer room should be locked and marked with the words "The computer room is heavily located and idlers are not allowed to enter." The equipment room must ensure that there is no possibility of rain and snow intrusion, good ventilation and heat preservation, and dehumidification should be kept clean, dry, free of dust, smoke and corrosive gases. There should be no other items except tools and equipment necessary for inspection and maintenance. Cleaning and lubrication of elevator car guide shoes. Everyone knows that the guide shoes run on the guide rails, and there is an oil cup on the guide shoes. To prevent the passenger elevator from generating frictional noise during operation, the oil cup must be regularly refueled and the guide shoes must be cleaned, and the car should be cleaned. Maintenance of elevator hall doors and car doors. Elevator failures are usually on the elevator hall door and car door, so attention should be paid to the maintenance of the hall door and car door.






2. The fire extinguisher must have
A fire extinguisher capable of extinguishing electrical fires should be installed in the machine room. When the elevator is not used for a long time, the main power switch of the machine room should be disconnected. Except for the specified elevator equipment, no sundries, water pipe type gas pipeline, etc. shall be laid in the hoistway. The hoistway should be kept clean and tidy, and there should be no tower ash and dust. The repaired elevator should be tested and inspected several times, and then put into formal operation after confirming that it is correct.


The elevator has undergone the replacement of important parts and should be tested for several times. After confirming that it is correct, put it into operation and make relevant records.



3. Precautions related to maintenance
Except for the work where the elevator car must stop at the B2, B1, and other upper floors, the daily maintenance and repair of the elevator (changing lights, repairing the buttons in the car, etc.) must be driven to the lowest floor (B3, B4) ) And then perform related operations. After the elevator is maintained, the elevator should be tested for several times to confirm that there is no abnormality before putting it into formal operation. If the elevator needs to be powered off during the maintenance work in the machine room, the corresponding power switch should be carefully confirmed and then the switch should be opened to avoid the emergency stop of the elevator caused by the wrong operation. For an elevator failure report, the maintenance worker should carefully check the elevator failure situation. To avoid the occurrence of unresolved elevator failures or magnification of the real problem.


Elevators need constant maintenance. Sometimes not only passenger elevators need to be maintained, but also the elevator's machine room needs frequent maintenance. The elevator environment is also very, very important. The machine room environment will affect some elevator storage problems. Therefore, everyone must be carefully and strictly checked every time they work, and the replacements must be replaced in advance. Only in this way can the quality of the elevator be guaranteed.
