How to choose the villa elevator

Summary: With the improvement of people's living standard, many rich people have their own villa and install home elevator inside. In the installation and purchase of home elevator, may not pay too much attention to its type, different families will have to use different kinds of villa elevator. So what are the types of home elevators? How to choose the villa elevator? The following is a small introduction to the types of home elevator and the choice of knowledge. First, what are the types of home elevator

Home elevator is mainly divided into traction elevator, screw elevator, hydraulic elevator several structures.

1, traction home elevator

Home traction elevator is divided into the traditional traction wire rope ladder and new traction steel belt ladder. The traction machine is located at the top of the shaft, and the traction wire rope/steel belt connects the car with the counterweight device through the traction sheave. A guide wheel is placed on the traction sheave so that the car and the counterweight can run normally in the shaft without touching each other. The electric motor rotates to drive the sheave, which drives the wire rope/steel belt to drive the car and the counterweight to operate relative to each other.

Advantages:

(1)Smooth operation, energy saving and environmental protection

The main machine adopts permanent magnet synchronous gearless traction machine, which has low noise and the power is only more than one kilowatt. The host is located at the top, and the noise source is farther away.

(2) Flexible structure, economic price

The traction elevator is also divided into gantry type and backpack type, platform type and car type, steel belt and steel wire rope, so it can be designed according to the actual situation on the site. The traction elevator belongs to the modern products, the production of modern relatively save a lot of cost.

Disadvantages:

(1) The requirements for civil construction are slightly higher, the top floor requires more than 2600mm, and the pit is reserved for more than 200mm.

(2) There are more manufacturers, the quality varies.

2, screw home elevator

Screw elevator adopts electric motor as the power source, the motor is connected to the nut through the belt, and the nut teeth and screw teeth between yin and Yang meshing, when the electric motor work, drive the nut in the screw movement, so as to drive the car for up and down movement. Higher safety because in fact there has been something underneath the top, even if the loss of power, free-fall decline, the screw also has to drive the motor to do a larger negative work, the decline will be very slow, so sit on this elevator will not fall, and as long as the screw can be locked to prevent the free-fall decline.

Advantages:

(1) low civil construction requirements, high space utilization

Screw elevator pit only 50mm, the top floor requirements are very low. And the screw elevator is platform type, no car wall structure, high space utilization rate.

(2) Simple structure, high safety

Screw home elevator has simple structure, fewer wearing parts and less maintenance troubles in the later stage. The structural principle of the screw elevator makes the screw elevator will not appear the phenomenon of top and bottom squatting, so the screw elevator is also the first choice of the duplex building to add an elevator.

Disadvantages:

(1) Mechanical noise

Screw elevator is a nut rotating on the screw, so the mechanical noise is bigger than other elevators, and the source of noise is closer.

(2)Slow running speed

The speed of screw elevator is only 0.15m/s, and the general traction elevator can do 0.4m/s, which is a big difference in speed.

3, hydraulic home elevator

Hydraulic elevator (hydrauliclift) rely on hydraulic drive elevator. Hydraulic elevator is through the hydraulic power source, the oil pressure into the cylinder so that the plunger for linear movement, directly or indirectly through the wire rope to make the car movement elevator. Hydraulic elevator is a product of integration of machine, electricity, electronics and hydraulics, which is composed of the following relatively independent but interconnected systems. Pumping station system, hydraulic system, guiding system, car, door system, electrical control system, safety protection system.

Advantages:

(1) Hydraulic elevator has low requirements on civil structure

Top floor height can be installed as long as there is more than 2600mm, and the pit can be satisfied with more than 100mm.

(2) Hydraulic elevator will not overspeed out of control

Disadvantages:

(1) Lack of comfort

The noise source generated by the motor and the oil pump is relatively close to each other, the operation is not smooth, and the speed regulation is adjusted by the oil volume and pressure of the pump at the pumping station, so the elevator has a jittery or sinking sensation when it is running.

(2) there will be oil leakage phenomenon

After the expiration of the service life of the cylinder piston, or the existence of wear and tear rupture, the hydraulic oil will leak into the shaft, which is easy to cause the indoor air is contaminated with oil.

Two, villa elevator how to choose

1, safety

General brand elevator must have a third party to test, after the acceptance of the professional institutions of the elevator, safe, reliable and guaranteed, can be used without fear. In addition, when choosing to purchase a villa elevator, it is important to understand the safety components of this elevator, safety configuration. Villa elevator in the necessary safety configurations are backup power supply, emergency call for help outside the telephone system, to ensure the safety of private users of the elevator.

Home elevators must be regularly maintained to confirm the safety of the elevator and whether the elevator can continue to operate and use, by the way, to repair the faults and hidden dangers found in it.

2, civil construction

Trailing elevator, screw elevator, hydraulic elevator, different types of civil construction requirements are different. The common traction elevator needs to take up a certain amount of shaft space, using the shaft made of concrete, but also can be made of steel structure shaft and glass curtain wall to create a sightseeing elevator; the depth of the pit is required to be at least 50cm; in addition, there are certain requirements for the height of the top floor.

Villa houses have a reserved shaft, you can compare the width and depth of the car according to the size of the shaft width and depth data to correspond to the selection of the appropriate car model. There is no reserved shaft can also choose the model of the elevator, according to the different models of the reserved size space needed to build a new shaft.

3, price

The total cost of installing a villa elevator includes the combination of equipment cost, civil construction cost and installation cost. When customizing a home elevator, the civil construction and installation fees are also a cost that should not be ignored. Generally speaking, the installation and civil construction fees for traction and hydraulic types account for about 15-25% of the total cost.

Villa elevator according to different grades, different configurations, different performance, imported and domestic, the price difference will be very obvious. The approximate price of different grades of home elevators can be referred to the following range.

Economic: the standard equipment price of about 10-15 million

Comfort: the standard equipment price of about 15-20 million

High-grade: the standard equipment price of about 20-25 million

This is the reference cost of the standard equipment, if there are special customization requirements for the car and the door, the cost will need to correspondingly increase from a few thousand dollars to a few thousand dollars.

4, maintenance

Ordering a home elevator, after signing a maintenance contract, the manufacturer's professional maintenance personnel need to regularly maintain the elevator, inspection. After the expiration of the free warranty period, it is also necessary to regularly do maintenance and repair of the elevator each year, this part can not be saved, is responsible for the safety of themselves and their families. Choose a regular and reliable brand can ensure that the later parts replacement and maintenance materials are original, more assured and reliable.

5, appearance and operation
