Design of elevator shaft:
In the villa decoration design, you should first find an elevator professional, tell the elevator professional what kind of function the elevator you want to install can achieve, can carry the ideas of several people, and then ask him to give you a design scheme.
Then tell the decoration designer these data, so that he should fully consider these factors in the design and meet these conditions. Remember, this is crucial.
2. Elevator selection:
At present, there are many elevator manufacturers in China, ranging from large to small, and there are many kinds of products. At present, there are the following important elevators for users to choose from.
a. Traction villa elevator
The traction driven elevator has counterweight, which is lifted or dropped by the traction motor in the machine room pulling the steel wire rope. One side of the steel wire rope is the elevator and one side is the counterweight. The main advantage is energy saving and high efficiency. The disadvantage is that the counterweight occupies hoistway space, so the hoistway needs to be quite small.
b. Forced traction elevator
Compared with traction elevator, its obvious disadvantages are limited lifting height, low energy consumption and high speed. However, its advantage is that it occupies a large shaft space.
c. Screw elevator
The screw elevator adopts the driving structure of nut screw, which is also an inorganic room elevator. Because of its structural safety, there is no pit, no counterweight and no lift car. Since it has a shaft and space utilization, it can be used in villas and duplex buildings. It has been popular in the European household market for nearly 40 years. (Note: the remaining villas in European and American countries are 2-story villas with relatively small single floor area, which is different from China's national conditions.)
First, the cost is low. Generally speaking, the price of installing a screw elevator is 2 to 3 times that of installing a traction elevator, and it is getting lower and lower;
Secondly, the screw elevator feels noisy because the motor rises and falls with the platform;
Third, the running speed of screw elevator is high, and the theoretical speed is 0.15m/s, that is, the lifting point in one minute is only 9m. Villas with more than three floors are not recommended;
Fourth, all parts of the elevator are imported parts, so the delivery cycle is short, usually about 6 months.
d. Hydraulic elevator
Hydraulic elevator refers to an elevator that uses the hydraulic power source to put oil pressure into the oil cylinder to make the plunger move in a straight line, and indirectly or directly make the car move through the steel wire rope.
Disadvantages: the hoistway occupies a large space and has low noise;
Advantages: high speed.
