Home hydraulic elevator development trend Hydraulic elevator working principle

With the improvement of social standards, many homes will be equipped with a separate home elevator, which is more convenient to go up and down the stairs. Home elevators currently have two main types of mainstream products: machine-room-less hydraulic elevators and machine-room-free elevators. In terms of function, users can choose hand-pull semi-automatic doors and fully automatic doors with car doors. The following Xiaobian focuses on hydraulic elevators and sees the development trend of home hydraulic elevators and the working principle of hydraulic elevators.

Hydraulic elevator

Hydraulic elevators rely on hydraulically driven elevators. 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.

Hydraulic elevator development trend

Energy saving and environmental protection are the trends of various technologies in the world today. Although the hydraulic elevator is still an important ladder in elevators, it still holds a high market share in the entire elevator market, especially in developed regions in Europe and America. However, in the current popularity of “green products”, hydraulic elevators are not "Greenization", as well as the disadvantages of large installed power and severe energy consumption, have become major problems that restrict its development and application. Therefore, how to reduce the installed power and energy consumption of hydraulic elevators, realize the energy-saving and high-efficiency operation of hydraulic elevators, and make hydraulic elevators become a green product is an important direction for the development of hydraulic elevator technology.

Home hydraulic elevator features

1. Smooth operation and comfortable ride.

The elevator's power system and fuel tanks are made up of imported products as a core component. They have excellent stability during operation and can be compared to passenger lifts that are commonly used in hotels. The advanced hydraulic system can realize automatic stepless speed change, which changes with the load pressure and makes the speed curve of the elevator run smoothly, so it has good comfort when riding.

2, good security and high reliability

The hydraulic elevator is not only equipped with the safety devices of common traction elevators, but also has an emergency manual lowering valve. When the power supply fails, the car can be lowered to the nearest floor position to facilitate the manual opening of the door and the passengers can get out of the car safely. Car. In addition, the manual pump can also operate the manual pump to pump out high pressure oil in the event of a system failure, causing the car to rise to the nearest floor.

Pipeline rupture valve: When the hydraulic system pipeline ruptures and the car stall drops more than 1.3 times of the rated speed, it can automatically cut off the oil circuit and stop the car from going down;

Overloading device: When the car is overloaded, an overload signal is issued and the car stops running when overloaded;

Oil temperature protection: When the oil temperature in the oil tank reaches 70 degrees Celsius, the oil temperature protection device sends a signal and the elevator stops using it. When the oil temperature drops, the elevator can be started.

3, low noise, more suitable for home use

The hydraulic system uses a low-noise screw pump. At the same time, the pump and motor are designed as a submersible structure, which constitutes a pumping station and greatly reduces noise.

4, Villa elevator size advantages

The product has the design advantage of miniaturizing the floor and maximizing the seating area in the car.

Traction home elevators are equipped with imported high-quality gearless traction machines and advanced frequency conversion controllers, which have excellent performance in noise reduction and energy saving. This traction type home elevator also uses a machine-room-less design, requiring only 300 (mm) deep pits. Specific technical parameters and configurations are as follows:

1, load: 320 (kg).

2. Speed: 0.4 (m/s).

3, well size: 1500x1500 (mm).

4, the car (section * deep * high): 950x1100x2100 (mm).

5. Pit depth: 300 (mm).

6. Top height: 2600 (mm).

7, control mode: microcomputer, frequency control.

8, open the way: automatic doors (car door, floor door).

9, power supply: 220 (v) or 380 (v) -1.1 (kw).

Hydraulic elevator working principle

(1) Lift rises

When the start button is pressed, the solenoid valve is energized, the oil inlet opens → the reversing valve opens to the left → the speed control valve opens → the hydraulic control check valve opens → the quick-change pipe joint opens → the telescopic cylinder moves. At this time, the hydraulic cylinder pushes the station person. As the platform rises, its rise speed is adjustable;

(2) Lift falls

When the downward solenoid valve is energized, the control valve is opened, the reversing valve is turned right, and the control valve of the pilot-controlled check valve is opened. After the check valve is opened, the pressure oil of the pump returns to the tank through the relief valve. The oil in the hydraulic cylinder is opened by the quick-change pipe joint under the action of the platform's own weight → the hydraulic check valve is opened → the check valve is opened → the change valve is returned to the right position

Summary: The relevant information about the development trend of home-use hydraulic elevators and the working principle of hydraulic elevators is introduced here for everyone. I hope this article will be helpful to everyone. If you still have something you don't understand, you can leave a message to Xiaobian at the bottom.
