Passenger elevator is very common in our days. Elevators need constant maintenance. We all know that, so many people will ignore some precautions for elevator machine room maintenance. The elevator machine room is the place where maintenance personnel often stay, so we should pay more attention to the environment of the machine room. Now let me introduce to us what needs to be paid attention to in the maintenance of the machine room environment of the elevator maintenance common sense?

1. No entry for idlers

The computer room should be managed by protection and maintenance 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, ensure that it is well ventilated and insulated, and the dehumidification should be clean, dry, free of dust, smoke and corrosive gases. In addition to checking and repairing all necessary things and equipment, there should be no other items. Cleaning and smoothing of elevator car guide shoes. We all know 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, it is necessary to regularly refuel the oil cup and clean the guide shoes, and the car should be cleaned. Maintenance of elevator hall doors and car doors. Elevators show faults generally on the elevator hall door and car door, so pay attention to the maintenance on the hall door and car door.

2. A fire extinguisher is necessary

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 revised elevator should be tested and checked for several times, and then put into formal operation after it is confirmed that it is correct. If

The important parts of the elevator have been replaced and should be tested for many times. Put it into operation after acknowledging that it is correct, and make relevant records.

3. Precautions related to maintenance

Except for the operations where the elevator car needs to stop at the B2, B1, and other upper floors, it is necessary to drive to the lowest floor (B3, B3, B3, B3, B3, B3, B3, B3, B3, B3, B3, B3, B3, B3, B3, B3, B3, B3, B3, B3, B3, B3, B3, B3 B4 layer) and then perform related operations. When the elevator maintenance is over, the elevators under maintenance should be tested for several times and confirmed that there is no abnormality before putting them into formal operation. If the elevator needs to be powered off during maintenance operations in the machine room, the corresponding power switch should be carefully recognized and then the switch should be opened to prevent the emergency shutdown of the elevator caused by misoperation. For the elevator fault report, the maintenance worker should carefully check the elevator fault condition. To prevent the occurrence of real problems that have not been dealt with, the elevator malfunctions again or the malfunctions expand.

Elevators need constant maintenance, so sometimes not only passenger elevators need maintenance, but also the elevator machine room needs frequent protection. The elevator environment is also very important. The machine room environment will affect some elevator storage problems. Therefore, it is necessary for us to check carefully and strictly in every homework, and we must change early. Only in this way can the quality of the elevator be ensured.
