The difference between three types of home villa elevator

Hydraulic home elevator

Overview: Hydraulic lift Hydraulically driven elevator. A hydraulic elevator is an elevator that uses a hydraulic power source to press oil into a cylinder to make the plunger move linearly, and directly or indirectly through the wire rope to move the car. Hydraulic elevators are mechanical, electrical, electronic, and hydraulic integrated products and consist of the following relatively independent but interrelated systems. Pumping station system, hydraulic system, guiding system, car, door system, electric control system, safety protection system.

1. Hydraulic home elevator advantages

Hydraulic elevators have low requirements for civil engineering structures. The top floor height can be installed with more than 2600mm, and the foundation pit can meet more than 100mm.

The hydraulic elevator will not run out of control due to speeding, and it is easy to achieve self-rescue. Hydraulic elevators will not be subject to top-lifting or flooding, and hydraulic elevators can use backup batteries to achieve self-rescue features.

2. The disadvantages of hydraulic home elevators

Lack of comfort

The noise sources generated by the motor and the oil pump are relatively close, and the operation is not smooth. The speed regulation is regulated by the fuel and the pressure of the pump of the pump station. Therefore, when the elevator is running, there is a feeling of jitter or sinking.

There will be oil leakage

After the service life of the cylinder piston expires, or if there is wear and tear, the hydraulic oil will leak into the well, which will easily cause the indoor air to be polluted by the oil.

Screw type home elevator

Overview: The screw-type elevator uses the motor as the power source. The motor is connected with the nut through the belt, and the yin and yang mesh between the nut teeth and the screw teeth. When the motor is working, the drive nut moves on the screw, which drives the car to move up and down. . The safety is higher because in fact there is always something to withstand, even if the power is lost, the free fall will drop, the screw will also drive the motor to do more negative work, the decline will be very slow, so the ride will not fall, and Just lock the screw to prevent free fall.

1. Screw home elevator advantages

Low civil engineering requirements and high space utilization

The screw elevator pit only needs 50mm and the top floor is very low. And screw elevator is a platform type, no car wall structure, space utilization is relatively high.

Simple structure and high safety

The screw-type home elevator has a simple structure, fewer vulnerable parts, and less customer maintenance troubles. The screw elevator structure principle does not allow the screw elevator to have the phenomenon of top-lifting and blinding, so the screw elevator is also the first choice for installing the elevator in the double-floor building.

2. Shortcomings of screw type home elevator

Mechanical noise

The screw elevator is a nut that rotates on the screw, so the mechanical noise is larger than other elevators, and the noise source is closer.

Slow operation

The speed of the screw elevator is only 0.15m/s. Generally, the traction elevator can achieve 0.4m/s, and the speed difference is relatively large.

Traction home elevator

Overview: Domestic traction ladder is divided into traditional traction rope ladder and new traction steel belt ladder. The traction machine is located at the top of the hoistway. The traction rope/steel belt connects the car and the counterweight device through the traction sheave. The guide wheel is placed on the traction machine so that the car and the counterweight run normally in the hoistway without colliding. The motor drives the traction wheel to drive the steel wire rope/steel belt to drive the car and the relative operation of the counterweight.

1. Traction home elevator advantages

Smooth operation, energy saving and environmental protection

The main machine adopts a permanent magnet synchronous gearless traction machine with low noise, and the power is generally only 1 kilowatt. The host is located at the top and the noise source is far away.

Flexible structure and economical price

Traction elevators also have gantry type and backpack type, platform type and car type, steel belt and steel wire rope. According to the actual situation of the site, design suitable solutions. Traction elevators are modern products, and the modernization of production is relatively cost-effective.

2. The drawbacks of traction type home elevators

Slightly higher civil construction requirements
