There are several possibilities for the abnormal sound of the elevator operation
As an important means of transportation in modern buildings, elevators have brought great convenience to people's lives. However, sometimes we encounter abnormal noises when the elevator is running, which will not only affect the normal operation of the elevator, but also bring anxiety and worry to passengers. So, how many possible reasons are there for abnormal noise in elevator operation?
First of all, we need to understand the basic composition and operation principle of the elevator. The elevator is mainly composed of machine room, traction system, door system, control system and car. During the operation of the elevator, the various parts work together to lift the car through the traction of the traction rope. As a result, elevator squeaks can stem from faults or problems with these components.
Next, let's analyze the possible causes of abnormal elevator noises one by one:
1.Traction system failure: The traction system includes parts such as traction machine, traction rope and guide wheel. If these parts are worn, loose or damaged, it will cause the elevator to run abnormally. For example, loose or broken traction rope will cause the car to shake and make abnormal noises during operation.
2.Door system problems: The door system includes door motors, door drive chains and other parts. If the door motor fails or the chain is loose, it will cause the door to open and close smoothly and produce abnormal noise. In addition, improper lubricant used in the door system can also cause abnormal noises.
3.Control system problems: The elevator control system includes PLC, frequency converter and various sensors. If these parts are faulty or the signal is abnormal, it will cause the elevator to run unstable and produce abnormal noise. For example, sensor failures can cause elevators to start and stop frequently and produce abnormal noises.
4.Car problem: The car is the main area for passengers to ride, if there are foreign objects inside the car, the car bottom shock absorber is damaged or the fixing screws are loose, etc., it will cause abnormal noise in the car during operation.
5.Other reasons: In addition to the above main reasons, there are other factors that may cause abnormal noise in the elevator. For example, poor lubrication of guide rails, water seepage in the pit, foreign objects in the hoistway, etc.
To sum up, there are many possible reasons for abnormal noise in elevator operation. In order to ensure the normal operation of the elevator and the safety of passengers, we need to investigate and deal with these possible causes one by one. In the process of investigation, we can take the following measures: first, conduct a visual inspection of each part of the elevator to see if there is an obvious fault or abnormality; Secondly, the sound during the operation of the elevator is monitored and analyzed through tools such as stethoscopes; Finally, according to the inspection results, corresponding maintenance measures are taken, such as replacing parts, adjusting positions, filling lubricants, etc.
In addition to daily inspection and maintenance, we also need to regularly conduct comprehensive inspection and maintenance of the elevator to ensure its normal operation and safe use. At the same time, when taking the elevator, you should also pay attention to the operation status of the elevator, and report to the maintenance personnel in time if you find any abnormalities.
In short, abnormal noise in elevator operation is a problem that needs to be paid attention to. By understanding the basic structure and operating principle of the elevator, analyzing the possible causes, taking corresponding investigation and treatment measures, and strengthening the daily maintenance and maintenance work, we can effectively reduce the occurrence of abnormal elevator noise and ensure the comfort and safety of passengers.
