Elevator does not close the door or repeatedly opens and closes the door: there are debris blocking the light curtain or door contact plate at the entrance or sill.

The elevator stops on the first floor and the door does not move: the fire emergency landing function of the elevator is triggered by smoke or thermal sensors inside the building.

Deng laohai.Dragging Method&ndash& mdash; AC dual speed,Deng laohaiSightseeing elevator household use, Low speed elevators with frequency modulation and speed regulation often use AC dual speed (AC -) It changes the number of poles of the electric motor to achieve speed regulation, allowing the elevator to have a low-speed operation process before the leveling brake, while the main disadvantages are poor comfort. The straight elevator starts frequently, and the impact current during startup is too high, increasing power consumption. This type of elevator is now commonly used for freight elevators.

The elevator suddenly opens the door and does not move after leveling, but automatically resumes operation after a few minutes: The elevator (escalator) has been running for too long, and the motor overheats. To prevent burning out, the motor cools down and automatically resumes operation.

.Passengers wearing long skirts and strapping sandals when riding on the escalator should try to stand slightly in the middle of the escalator to prevent shoes and clothing from being drawn into the escalator and causing danger, and to prevent skirts or pants from getting stuck.

If there is a reserved shaft in the villa residential area, the appropriate car model can be selected by comparing the width and depth of the elevator car based on the size, width, and depth of the shaft. If there is no reserved shaft, the leveling reference position needs to be re determined.

Reduce the overall noise of the machine. Due to the absence of noise from bearings during high-speed operation of an asynchronous motor and the absence of noise from worm gear transmission, the overall noise can be reduced by 5-10db (A) Low energy consumption. From the working principle of permanent magnet synchronous motors, it can be seen that their excitation is achieved by permanent magnets and there is no need for the stator to provide additional excitation current. Therefore, the power factor of elevators can reach a very high level. At the same time, the rotor of the motor has no current and there is no problem of electronic loss. Generally, it reduces consumption by 45% -60% compared to asynchronous motors. Due to the lack of low efficiency and high energy consumption worm gear transmission pairs, passengers, and fire-fighting equipment in the event of a fire. They are used to transport frozen goods in large cold storage or refrigeration workshops. However they need to meet the requirements of sealing the door leaves and guide rails at the moving parts. Professional household elevators, villa household elevators,Deng laohaiVertical hydraulic elevator, household elevator manufacturers, and small household elevators have stable, safe, reliable, and maintenance free performance, and their technical level has reached the domestic level, Meet the advanced level of international similar products and immersion requirements

Variable cost.2. Different types of civil engineering traction elevators, screw elevators, and hydraulic elevators have different requirements for civil engineering. Common traction elevators require a certain amount of hoistway space,Deng laohaiMobile hydraulic turnover machine, which can be made of concrete, steel structure hoistways, and glass curtain walls to create sightseeing elevators; The depth of the pit should be at least 50cm or more; Additionally, there are certain requirements for the height of the top floor.

When wearing high heels, be careful not to step on the gap between the pedals, as not wearing shoes is more likely to be pinched by the toothed plate.

The braking system of the elevator is usually closed, which means it is in the braking state when there is no power, and only when it needs to be turned on, will the power turn on the brakes. So as soon as there was a power outage, the brakes closed and the elevator was braked in mid air. When the elevator descends abnormally, it is cut off

Home elevators are different from special products such as public spaces, professional home elevators, villa home elevators, home elevator manufacturers, and small home elevators. They are 20 year old brands with advantages in price and guaranteed quality. Considering the limited installation space, and small lifting height, they pursue simplicity and miniaturization in design, and the existence of computer rooms is not necessary. Long term promotion of a domestic elevator manufacturer a 20 year old brand with competitive prices and guaranteed quality!

Recommendation and consultation.Elevator does not close the door or repeatedly opens and closes the door: there are debris blocking the light curtain or door contact plate at the entrance or sill.

The elevator must be a world-renowned brand with performance in key projects worldwide or domestically.

When wearing high heels, be careful not to step on the gap between the pedals, as not wearing shoes is more likely to be pinched by the toothed plate.

The difference between home elevators and ordinary public elevators is that the focus of home elevators and ordinary public elevators is different, with some indicators significantly reduced. For example, the load capacity of home elevators does not exceed 400kg, which is much lower than that of ordinary public elevators. Home elevators do not need to consider the issue of passenger flow, and the lifting speed is slower, ensuring safety. The lifting speed is generally between 0.3 to 0.4m/s, and running smoothly.
