- Q:Raise the height of 110 meters, do the machine room elevator feasible?
- But at least the speed of at least 2.0 or more
- Q:Elevator industry, the traction machine has permanent magnet synchronous motor and permanent magnet asynchronous motor two, what is the difference between them?
- AC motor to rotate requires two conditions: first, there is an active rotating magnetic field; second, there is a magnetic field driven by this active magnetic field. In general, the rotating magnetic field from the stator winding, three-phase AC power naturally formed a rotating magnetic field. The difference between a synchronous motor and an asynchronous motor lies in the source of the rotor magnetic field. The synchronous motor requires an excitation power source, or a permanent magnet, so that the rotor always has a magnetic field that can be driven by the rotating magnetic field provided by the stator. As long as the braking torque is reasonable, the final rotor speed can always reach the stator in the rotating magnetic field speed, that is, synchronous speed. This kind of motor is synchronous motor. Asynchronous motor is simply closed end of the whole family is relatively simple. The magnetic field of the rotor is derived from the rotating magnetic field provided by the stator windings to cut the current generated by the conductor in the rotor. In other words, the induced current generated by the rotating magnetic field cutting rotor from the stator produces a second magnetic field based on the rotor, and the rotor rotates due to the interaction of the two magnetic fields. The greater the difference in speed between the rotor and the rotating magnetic field, the greater the rotor current, and the stronger the effect of the two magnetic fields. As the speed increases, the rotor current is getting smaller and smaller, but never. This creates that the rotor speed must have a certain difference from the synchronous speed to maintain the rotating magnetic field to cut the rotor conductor. To maintain the continuous rotation of the rotor. The difference between this speed and the speed of synchronous speed is the slip rate. Asynchronous motor speed never reach the synchronous speed, so called asynchronous motor
- Q:What are the embedded parts in the elevator shaft?
- Most of the embedded parts made of metal, such as: steel or cast iron, wood, plastic and other non-metallic rigid materials. The prefabricated part (prefabricated part) is a pre-installed (buried) component in the concealed project, that is, the structure of the structure when the structure is placed, for the masonry when the superstructure of the lap. To facilitate the installation of external engineering equipment base fixed.
- Q:What is the meaning of E and F in the elevator?
- E emergency stop f fire
- Q:Do you want to be next to the elevator? What is the role?
- The airway next to the elevator should be the role of the smoke in the elevator when the fire is removed
- Q:What is the elevator?
- 1, the traction system: the main function of the traction system is the output and transmission power, so that the elevator running.The traction system is mainly composed of traction wire rope, guide wheel, reverse sheave .2, the guiding system of the main function of the system is limited Car and counterweight, so that the car and the counterweight can only be moved up and down along the guide rail.The guide system consists mainly of rails, guide shoes and guide rails. 3, car car is the transport of passengers and cargo The elevator car is composed of a car frame and a car body. The main function of the door system door system is to seal the entrance of the station and the car entrance. The door system consists of the car door, the floor door , Door opener, door lock device .5, weight balance system The main function of the system is relatively balanced car weight, in the elevator work can make the car and the weight between the weight of the balance to keep within the limit, to ensure that the elevator drag The system is mainly composed of counterweight and weight compensation device. 6, electric power drag system: electric drive system function is to provide power, the implementation of elevator speed control. Electric drag system by the traction motor, power supply system, speed Feedback device, motor speed control And other components .7, electrical control system: electrical control system is the main function of the operation of the elevator control and control.The electrical control system mainly by the operating device, the location display device, control panel (cabinet), leveling device, Equipment, etc. 8, the safety protection system, the right to protect the safety of the use of the elevator to prevent all accidents that endanger personal safety caused by the speed limiter, safety gear, buffer, end station protection device.
- Q:Recently look at the norms, the definition of these places more and more blurred, has been Mongolia, please help explain, thank you! More
- Stairwell refers to the location of the entire stairs in the building, sent to the top, including stairs and stairs platform. In addition, the first floor or the ground floor from the entrance hall to the stairs of the first step so far, in this range of space belongs to the staircase hall, is in the staircase projection level plane. The front room refers to the space from the building into the front room. It is quite when you enter the hotel hall. Elevator is the scope of the elevator to run, the elevator hall is the elevator where people stand or range. The elevator room is above the elevator, and the elevator is equipped with various control boxes and other spare parts. In fact, sometimes the staircase hall and the elevator hall is in a place, there is no clear distinction, the building, as long as you know what is probably in what position, do not distinguish so clear.
- Q:1, was asked whether the elevator shaft need to have legs, I would like to ask the cow in the end is what? 2, it is the elevator shaft in the excess part, or the necessary part? 3, if it is necessary, it should be responsible for the civil construction side, or the elevator is responsible for? 4 helium fudge silhouette every child Fu Fu, if it is redundant, that the elevator shaft had a cow, and whether the impact of the installation of the elevator? Please help people as soon as possible to help me, be grateful! More
- A: 1, the ox is used to install the elevator hall door to the ground, the general design of concrete, is in the hall under the mouth of the mouth of the elevator shaft about 100mm, 150 ~ 300mm high concrete components. Such as the design is not, you can use 75 * 75 angle with the expansion of the screws fixed in the hall under the mouth of the door on the line, which is usually installed when the elevator installation team to help dry wine, but finished remember to give people a little labor Ah, it's not easy. 2, it is not redundant, must have! But it is time to appear sooner or later. Above said two do not long-winded, and there is a kind of installation is to play when the ground to play a few expansion bolts have a good welded steel bar, supporting the concrete after the template can be poured. 3, as to who is the helium scraping care of the innocence care, I do not know! Then you have to see the contract Caixing, the general order has a clear order of the elevator, there is no steel legs. 4, if there is no impact on the installation of the elevator, but the installation process has changed it. 5 where are you from?
- Q:How can an elevator stop at the floor where you want to dock? Why the general height of the error is very small, very few elevator doors open, the elevator is not the ground and the ground alignment of the situation? If the wire rope encountered thermal expansion or contraction or long harvest and make up the ancient use of the current period, will not produce the length of change? This will not make the elevator dock can not be aligned with the floor of the floor? There is no possibility of docking with the ground floor height error of tens of centimeters, people need to climb out of the situation? More
- Oh, your question is very interesting. To be honest, my unit to do the product is about this. do you know? In fact, the elevator floor positioning is not only on the rope to capture and make up the ancient cast off the rough, but also in the floor of each layer on the positioning. Also, now the general elevator electronic core board are used in the intelligent positioning system. So this problem is generally not out of the problem. Of course, do not rule out special problems, such as all blackouts and so on.
- Q:What is the elevator room
- The floor is high and the building is equipped with an elevator.
