Advantages and disadvantages of elevator with inorganic room
2017-08-10
The elevator is relative to the machine room elevator is concerned, that is to say, the equipment in the engine room as far as possible on the premise of keeping the original performance miniaturization of the use of modern production technology, eliminating the room, the original room within the control cabinet, traction machine, xiansuqi to lift wells or wells at the top of the side, so cancel the traditional room. To meet customer's special requirements for height and roof.
First, the advantages of the inorganic room elevator compared with the elevator with the engine room
1, the advantages of no computer room is to save space, you can only under the host to do an overhaul platform.
2, because you do not need to have more room, the benefits of building structure and cost, which makes architects have greater flexibility and convenience in the design, to give designers more freedom at the same time, due to the cancellation of the room, for the owners, machineroomless elevator is lower than the construction cost of organic real lift the.
3, because of the particularity of some antique buildings and the overall design requirements on the roof of the elevator, must solve the problems in effective height, so the room elevator is very satisfied this kind of building, also in a scenic place, because the room on the floor from a height, and destruction of its local ethnic exoticism, if used the elevator, because do not have a separate set of elevator computer room, can effectively reduce the height of the building.
4, not easy to set up the elevator machine room places, such as hotels, hotel affiliated buildings, stone.
Two, inorganic room elevator and room elevator compared shortcomings
1 noise, vibration and limitations
No room for the placement of the popular host two: one for the host is placed above the top of the elevator hoistway, the guide wheel is connected, regardless of which way the above, the noise impact is very large, because due to the rigid connection, and the noise must be digested in the hole, plus brake the voice of the fan sound will enlarge. Therefore, the noise aspect, the inorganic room is obviously bigger than the computer room. In addition, the rigid connection of the main engine, the resonance phenomenon inevitably passed to the car and the rail, the car and the rail have a greater impact, so no room for comfort is significantly weaker than the computer room. Because of the influence of these two items, the inorganic elevator is not applicable to the high-speed trapezium above 1.75/s. In addition, due to the well support wall support is limited, so room elevator load are generally not more than 1150 kilograms, the load is too large too much bearing on the well wall, and we usually reinforced concrete thickness 200mm, masonry structure is usually 240mm, not suitable for carrying too large, so in 1.75m/s, the following 1150 kg machineroomless can replace a trapezoidal room, and large load high speed elevator, machine room elevator is obviously better than that of inorganic room elevator.
2, temperature influence
Lift the quantity of heat is relatively large, and its various electronic components under high temperature are relatively poor, and now the room elevator and machineroomless elevator adopts gearless permanent magnet synchronous machine, the permanent magnet synchronous motor temperature should not be too high, otherwise easy to cause "loss" phenomenon. Therefore, now the national standard for the temperature of the computer room, exhaust air are clearly defined. The main heating parts are in the room without host hole, because there is no corresponding cooling and ventilation facilities, resulting in the effect of the elevator machine room temperature on the mainframe and control cabinet is relatively large, especially transparent sightseeing elevator is more suited to install room elevator, elevator set heat cannot discharge cohesion. Therefore, the choice of such elevators must pay attention.
3 、 troubleshooting and personnel rescue
Inorganic room elevator maintenance and management is better than a room elevator. The elevator maintenance and debugging more trouble, because the elevator is again good also inevitably fails, without machine room elevator is installed in the beam due to the host, the host in the hoistway, if the host (motor) problem is very troublesome, so, the national standard stipulated the elevator safety window room can not additionally, no room must be added, so that the convenience and safety of rescue and repair and maintenance of the host, so in the maintenance room elevator to occupy the absolute advantage, if it is recommended to use a room space. In addition, in personnel rescue, inorganic room elevator is also very troublesome, in the event of power failure, must install emergency power supply, general elevator emergency power supply need to invest more funds.
