- Q: No machine room elevator working principle
- And the general elevator a principle, that is, the host control cabinet in the shaft
- Q: How many meters are needed to build a lift?
- Residential Design Code clearly states: seven or more residential or residential entrance floor from the outdoor design of the ground height of more than 16m residential must be set up the elevator. Note: ① the bottom of the store or other space as a multi-storey residential, the entrance floor of the building from the building's outdoor design of the ground height of more than 16m must be set up the elevator; ② the bottom of the floor or storage space of multi-storey residential, The entrance floor of the household entrance from the building outside the ground height of more than 16m must be set up the elevator; ③ the top floor of a set of two layers of thermocline residential, the thermocline part of the number of layers. The height of the building floor of the building is not more than 16m, the elevator can not be the elevator; ④ the middle layer of the building has the entrance to the outdoor ground and has a fire channel, the number of layers can be calculated from the middle layer ; In addition, "Office Building Design Code" also provides: 4.1.3 five and five floors above the office building should be set up elevator.
- Q: As we all know, press the button, the elevator door will open, and each floor body has a door (Note: the door in the "floor"). But the elevator to pay for Cao Zhi 丨 pedal check boxing gnosis itself has a door? In other words, the elevator is a hexahedron or a pentahedron More
- The elevator has a car door and hall door of the points, the elevator in the hoistway running, car door closed, hall door closed, the elevator can be safe to run. But after the door, the professional point called the flat area, car doors and hall doors are open, so passengers can do the elevator out of the elevator. Hall door is passive, is driven by the car door opened, car door above the door machine used to drive the car door. The elevator is of course a hexahedron. Up and down, around, inside and outside. The so-called outside is the side of the door, this side is the door to open the side.
- Q: Elevator door in the sub-door and the difference between the two points is defined as the god of God ah? Have to answer. The
- In the middle of the door: two doors, separated from the middle, each opened to both sides of the double fold: double folding elevator door has four door panels, the elevator door to open on both sides, every two door board through the two Danchuo door arm to the equivalent
- Q: Why is the elevator in the Zifu Fu letter of the gearless traction machine do not use the upstream overspeed protection of the rope device? More
- It will not slip car!
- Q: The above questions are in the civil design code 6.8.1. But do not know what reason. More
- The building of each service area unilateral arrangement of the elevator should not be more than 4 is the civil design code 6.8.1, and civil building design specifications are also according to safety design parameters to carry out the relevant provisions of the unilateral arrangement of the elevator should not More than the main consideration of the current dynamic load may be beyond the scope of the conventional design parameters of the security range, so the provisions of the article is not appropriate words, of course, to meet the needs of the depth of the structural design of the theoretical calculation can also be designed. Architectural Design Code: The minimum technical requirements for new buildings issued by the government or the legislature are part of the building code system. Introduction: The building legal system is divided into three levels: legal, normative and standard. The law mainly deals with administrative and organizational management (including punitive measures). The specification focuses on the comprehensive technical requirements. The standard emphasizes the individual technical requirements. The distinctions between national architectural laws and regulations are not the same, as Japan incorporates some of the main elements of the architectural design code into the Building Standards Act and its Implementing Order as a subsidiary of the law; the Soviet Union included architectural design specifications in the standard Inside.
- Q: How much does the increase in the number of stops for an elevator?
- This score is a new elevator installation or an old elevator installation. If the old elevator to install the cost may be high, the room to move, all the wire rope to move. If the new elevator installation, 8-10 also about 6000, but also depends on what you need to configure. If more than 16, there is a cardinal problem. Is to double the child attack powder chatter mad Wei Wei two. hope this helps
- 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: Tangled title: the woman came home and found to be a man to track, when she walked into the elevator when the man came in. She pretending to calm the men choose the floor, when the man
- This sentence: every word is a point of information (comma-based): the first sentence, "home" does not mean "back to the home" (back home is "upstairs", this is "downstairs"); 2 women into the men with, the women get out! So must enter; 3,4,5: because it is downstairs, men positioning "two", like, on the second floor, a layer easily lead witnesses! She is three in order to advance in advance! 6: the man took the knife to the woman stabbed, the elevator door closed, the woman has been dying, "the results of a woman die! Positive solution: a woman by the end of the "three" immediately out of the elevator door to escape the product theory: the problem is the subtle nature of the use of people drop normal thinking, logical thinking! That is, the drama played! So confused you!
- Q: What are the contents of the elevator property every day?
- 1, observe the operation of the elevator every day (up and down operation, speed, open the door, leveling, etc.). Daily engine room inspection, you must check the traction machine transmission parts of the situation. 2, check the motor and traction machine gear box oil level is in line with the requirements. Check the control cabinet, power distribution cabinet and other electrical equipment terminals, with or without loose burning phenomenon. 3, check the circuit breaker, contactor with or without contact, pull the arc phenomenon. 4, check whether the grounding point meet the requirements. 5, check the speed limit to work the operation, timely refueling. The election, external election button work, whether sensitive. 6, check the safety protection device installation parameters and action test status is consistent with the standard. 7, check the car lighting and fan. Each indicator light, replace the damaged parts. 8, check the fire ladder fire function. 9, monthly inspection boots and boots lining. Check the shaft position sensor and so on. 10, the monthly inspection car roof overhaul switch and the upper and lower forced slow switch. Check and adjust the rope tension. 11, monthly cleaning room, cleaning car roof and pit health. Check the buffer oil level and reset the situation. 12, monthly inspection wells along with the cable. Check the balance chain suspension and rotation. 13, the monthly inspection room car door-related size, and make the appropriate adjustments. 14, the monthly inspection and adjustment of brake braking torque and brake shoe work conditions. 15, the monthly cleaning of the corridor chute hygiene and impurities, so that the door and car doors without blocking. 16, the monthly inspection, adjust the door and the door and the lower end of the station speed, limit switch, so that the correct location, reliable function. Elevator machine performance adjustment check, must be recorded, and archived.
