　　Let's take a look at the overall quality management standards for installing elevators in old buildings

　　The three main tasks of installing elevators in old buildings are: mastering the progress of the project, controlling the quality of the process, and caring about immediate safety. In order to ensure that these three key indicators can be successfully achieved, before entering the construction project, it is necessary to prepare the necessary (executable and weakly executable) elevator installation construction work organization plan (plan), elevator installation construction quality assurance plan and elevator installation work safety plan according to the detailed situation of the construction site. To ensure that the current project progress, quality management of each connection point during the process, and safety and real-time management methods at all times during the process can be carried out in an orderly manner.

　　The diversity of elevator products installed in old buildings is that their assembly must be completed after the construction site and the building are connected, so the product cannot be assembled in the factory and the entire equipment is shipped. One process of the product must be carried out through the assembly work on site. The quality of the assembled product directly affects the overall quality level before the product is completed. Therefore, the assembly of the home elevator plays a very important role in the supply of the product.

　　When installing elevators in old buildings, if the key stages and key components have quality defects during the installation process and are not discovered or handled in time, a large part of the details will lead to product quality problems that are difficult to remedy in the future. The installation process of key stages and key components must strictly implement the process standards of each node in the "quality assurance plan" and the above-mentioned nodes, regulations, and processes in the quality management of the installation process. The process management and inspection of the single project process or process must be carried out, and the next step or process can be carried out after the inspection of the previous process or process is qualified. The key points of the assembly of several key stages and key components that need to be paid attention to during the installation process are discussed.

　　Safety power requirements for installing elevators in old buildings during repair

　　1. When the elevator is inspected or repaired on time, the main power supply must be turned off. The elevator cannot carry people or load vehicles. At the same time, warning signs with specific contents such as "maintenance stop use", "cannot reclose", "has been repaired, cannot start" should be hung at the floor door, the control box in the car, and the control box in the main machine room. During the trial operation, a full-time staff must be in charge. Only according to the order issued by the guiding staff can the warning signs be removed or the home elevator be started.

　　2. When installing elevators in old buildings for inspection, testing, maintenance, and cleaning, the main power switch of the main machine room must be turned off to ensure safety.

　　3. When inspecting and repairing elevators, be sure to use working voltages below 36V. Therefore, the elevator room, the pit of the elevator shaft, the top of the car or the bottom of the car should be equipped with low-voltage power plugs for maintenance.

　　4. The plastic shell of all electrical equipment of home elevators should have good grounding:

　　(1) Electrical equipment, cabinets, screens, boxes, boxes, and slots should be equipped with grounding terminals that are easy to identify.

　　(2) The color of the grounding wire is yellow-green insulated cable.

　　(3) The neutral wire and the wire connector should be separated from beginning to end. (Except for home elevator electrical control systems controlled by relays).
