MRL DRIVING SYSTEM
SCREW DRIVING SYSTEM
HYDRAULIC DRIVING SYSTEM
With the improvement of living standards, more and more people will consider installing a home villa elevator during home renovation. There are many classifications of household elevators on the market, such as traction elevators, screw elevators, hydraulic elevators, etc., which makes the general consumers dazzled and unable to choose. Next, the editor will elaborate on the advantages and disadvantages of various elevators to help you better choose during decoration and installation.
1. Towing a home elevator. Can be subdivided into traction gantry elevator, traction strong drive elevator and traction backpack elevator
The traction gantry home elevator is a reduced version of the elevator in the residential building and office building. The counterweight and the balance principle of the car are used. The car guide rails are on both sides of the car, and the permanent magnet synchronous gearless traction host is driven by the steel wire rope. The car runs up and down. The advantages are mature technology, wide application, stable operation, low power consumption and fast speed. The disadvantage is that there is counterweight, the size occupies a large area, the same car area, the shaft should be more than the size of the counterweight.
The only difference between the traction strong drive elevator and the gantry elevator is that there is no counterweight. Only the traction host is used to force the car to move up and down. The advantage is that after the counterweight is removed, the size of the shaft is small, but the disadvantages are also obvious. The power of the host is large, generally above 4.4KW, which is about three times that of the counterweight elevator.
The difference between the traction backpack elevator and the gantry elevator is that the car guide rail is on the side of the car, similar to the nature of the student carrying a school bag. The advantage of this is that the car guide rails are no longer provided on the left and right sides of the car, which saves the size of the shaft on both sides. However, the disadvantages are also obvious, because the guide rail is only on one side, and the car will compete with the guide rail on one side due to the weight during operation. After long-term operation, it is easy to cause large wear of the guide shoe, unstable operation and abnormal noise.
2. Screw elevator
The screw elevator relies on the mutual movement between the nut and the screw to achieve the lift of the car. It has no counterweight and does not need to be pulled by the main engine. The advantage is its low weight and low load bearing requirements on the floor. It is more suitable for the installation of duplex buildings and upper-floor flats, while occupying very little space.
The disadvantages of traditional screw elevators are also obvious, and the speed is slow, and it is generally not used for elevators with more than three floors. The noise source is close to the passengers, and the noise is loud. At the same time, the car has no car wall design, which is easy to be accidentally touched and cause the elevator to stop running.
Traction home elevators generally have restrictions on the height of the bottom pit and the top floor. The S3 elevators are accurately designed by perfecting the technology. The bottom pit can be installed at a minimum of 150mm and the top floor at a minimum of 2600mm.
3. Hydraulic elevator
The hydraulic elevator is an elevator that presses the oil into the cylinder to make the plunger move linearly through the hydraulic power source, and directly or indirectly moves the car through the wire rope. According to the connection method of car and hydraulic cylinder, hydraulic elevator can be divided into two types: straight roof type and side roof type.
Many cilents think the big problem is leak of cylinder. For that, we design a kind of cylinder, which can operate for a long time. To reduce the noise from pump station, low noise pump station is designed for our hdyraulic elevator. So if you want home lift with better price and quality, maybe China safely lift is your better choice.
