Elevator Maintenance Procedures Elevator Maintenance Notes

The elevator believes that everyone will not be unfamiliar. Because the type, use, drive, traction, and control of elevators vary widely, failures of various elevators are often not exactly the same. Periodically inspect and maintain the used elevators, eliminate the hidden troubles before they occur, take specific measures to eliminate them, and adjust the elevator's various faults. So what needs to be paid attention to elevator maintenance ? Next we will take a look and see.

What is elevator maintenance

Elevator maintenance take good care of lift The inspection, refueling, dust removal, and commissioning of safety devices for the elevator components that are in operation during the specified period. Including elevator traction wire rope non-destructive testing and lubrication maintenance.

[elevator maintenance steps]

1. After the elevator maintenance personnel arrive at the site, they should ask the elevator manager and the elevator driver about the elevator operation and fault conditions and make a record.

Second, maintenance personnel in the maintenance of elevators, maintenance, should be in front of each hall door hung "elevator maintenance, repair" signs.

Third, maintenance personnel in the elevator engine room inspection or refueling, should first cut off the main line of the elevator power supply, to confirm when no electricity can be checked and refueled.

[What should pay attention to elevator maintenance]

Mechanical components:

1. The traction machine of the elevator needs the lubrication of oil. There are two scales on the cover of the traction machine. Open the nozzle to check the oil should be in the middle of the two scales. If the oil is lower than the scale below, it means that the traction machine should be refueled. If no refueling, the elevator will run for a long time. It will not be well lubricated, resulting in the burning of elevator traction machines and motors. After the elevator has been running for a long time, the oil should be replaced in time so that the traction machine can always maintain fresh and good lubrication.

2. Elevator car guide shoe cleaning and lubrication. Everyone knows that the guide shoe runs on the guide rail and there is an oil cup on the guide shoe. To ensure that the elevator does not produce friction sound during operation, the oil cup must be regularly refueled and the guide shoe must be cleaned, and the cleanness of the car should be cleaned.

3. Maintenance of elevator hall doors and car doors. Elevator failure is generally more on the elevator hall door and car door, so pay attention to the hall door, car door maintenance. One is the refueling of the refueling area on the door's upper canopy, and it is well lubricated. The elevator will not make an unpleasant noise during operation and the opening of the door. Pay attention to the inspection of the elevator's safety touch panel or light curtain type touch panel switch wire. Because the frequency of the lift door is high, the switch wire will be damaged. This requires the maintenance personnel to check each work. Replacement must be changed in advance, do not allow users to doubt the quality of elevator products because of the door.

Electrical parts:

Electrical components are roughly divided into control panel and electrical switch of each safety circuit. It is the brain of the elevator and the central nervous system of the elevator. The start and operation of the elevator and the opening and closing of the doors are controlled by it. Therefore, it must be in daily maintenance work. It should be treated as if it were heavy. It is best not to short-circuit the elevator circuit in the control panel during work. When the elevator door system fails, someone has short-circuited the elevator door in order to make it easier to find the fault. This is very dangerous. The short-circuited door has the most accidents. why? If a person opens the hall door and extends his head inwards, then the elevator will just run up or down here, and the hall door cannot be stopped if it is short-circuited to the elevator, so the accident is very likely to happen. Therefore, we must not short circuit the safety circuit in daily maintenance work. If we must short-circuit, we must find out which safety component has a problem, which safety component needs to be short-circuited, and whether it is maintained or urgently repaired. After that, we must remove the short wiring in time.
The cleaning and lubrication described above are only for the wire rope itself. This is just one aspect of ensuring the safe use of the wire rope. In addition, the external conditions of the wire rope must be inspected, such as the surface wear of the traction sheaves and the geometry of the wheel groove, in order to ensure that the wire rope is always in good contact to reduce the friction during operation. Ensure the safe operation of the elevator.

Summary: The above are some of the notes on the maintenance of elevators by Xiao Bian. I hope to help everyone.

Brass Plated Steel Sawing Wire

Fine-gauge brass plated steel sawing wire plays an irreplaceable role in the production of solar wafers. The thickness of the silicon wafer cutting wire on the market is generally 120 microns. In order to reduce the loss of silicon blocks, fine-gauge and high-strength consumables are required as cutting accessories. According to the technology, ultra-fine specification high-strength brass plated steel sawing wire is a necessity for silicon wafer production. This Cutting wire as a consumable material is widely used in energy and utilities, aviation, equipment fields. Such as, solar wafer cutting, quartz material, monocrystalline silicon, polycrystalline silicon, etc.
