3-Floor Hydraulic Elevator

Many customers, when needing to install an elevator for a 3-story house, immediately think of a hydraulic home elevator . THANGMAYNIDEC will provide a detailed analysis of 3-story hydraulic elevators: their operating principles, real advantages and disadvantages, dimensions, cost, and comparison with other elevator technologies, giving you a comprehensive overview in the article below.

Features of a 3-Story Hydraulic Elevator

Among the various types of home elevators available today, the hydraulic 3-story elevator stands out, utilizing hydraulic technology with load capacities of 200kg, 250kg, 320kg, and 400kg for installation in 3-story houses or buildings. Hydraulic elevators operate using hydraulic oil pressure to raise and lower the cabin, instead of cables or screw shafts. The operating principle is based on Pascal's law.

• During upward movement: An electric motor pumps oil from the reservoir into the hydraulic cylinder. The oil creates pressure, pushing the piston upwards and pulling the cabin along with it.

• During descent: The control valve opens, allowing oil to flow from the cylinder back to the reservoir. The cabin descends gradually by its own gravity, with the speed controlled by a throttle valve. Notably, the descent phase consumes almost no electricity, saving 50% energy compared to cable-driven elevators.

Below are some advantages and disadvantages of hydraulic elevators for 3-story houses that you should consider before making a decision:

Advantages of a 3-Story Hydraulic Elevator

Three-story hydraulic elevators are a popular choice for many families due to the following advantages:

• Smooth operation: Due to its hydraulic oil-based operating mechanism, the elevator moves smoothly without jerking or vibration when starting and stopping at each floor.

• No pit required (or extremely shallow pit): Many modern hydraulic elevators have completely eliminated the pit requirement. Hydraulic cylinders can be located on the side or rear of the cabin, eliminating the need for traditional bottom dampers. This is particularly suitable for existing homes or renovated homes where breaking through the ground floor foundation is not feasible.

• Hydraulic safety mechanism: The cabin cannot fall freely. In case of power failure, the system will automatically return the cabin to the nearest floor. To return the cabin to the ground floor, simply open the manual release valve to allow the oil to drain slowly. This is a purely mechanical safety mechanism, independent of electricity.

• Energy saving: The hydraulic motor only operates when the cabin is going up. When going down, the cabin lowers by gravity, consuming almost no electricity.

Disadvantages of 3-Story Hydraulic Elevators

Despite its many advantages, hydraulic elevators also have certain limitations, as follows:

• Slower than cable/flat cable elevators: A 3-story hydraulic elevator has a speed of approximately 0.3 to 0.4 m/s (18-24 m/min), about 50% slower than a flat cable elevator (0.4-1.0 m/s). Climbing 3 floors (approximately 9m) takes about 22 to 30 seconds. The difference isn't significant for a 3-story building, but the slowness becomes more noticeable in 5-story or more buildings.

• Travel height limit: Hydraulic elevators are suitable for a maximum of 13m (approximately 4 floors). For buildings with 5 floors or more, the required pressure increases, the motor has to work harder, and its lifespan is reduced. For buildings with more than 5 floors, cable-driven elevators are a more suitable option.

• Regular maintenance of the hydraulic oil system is necessary: ​​Hydraulic oil needs to be checked and replaced every 12 to 18 months. Without maintenance, the oil will degrade, leading to unstable lifting speeds, oil leaks, and lifting noise.

• Risk of oil leaks due to poor installation: If the supplier uses low-quality oil pipes, valves, and seals, there is a risk of oil leaks after 2 to 3 years of use. Leaking hydraulic oil causes contamination, slipperiness, and affects the foundation structure. Prevention: Choose a reputable supplier with a warranty commitment for the hydraulic system.

• Noise from the pump: The pump of a hydraulic elevator is usually located next to the elevator on the bottom floor. Therefore, when the elevator is in operation, the pump will emit a loud noise that affects the shared living space of the family.

Structure and Technical Specifications of a 3-Story Hydraulic Elevator

Hydraulic elevators have different structural characteristics compared to cable-driven elevators; hydraulic elevators operate primarily based on a hydraulic oil pump system.

Structure of a 3-Story Hydraulic Elevator

A hydraulic elevator consists of the following components:

• Oil reservoir: This is where all the hydraulic oil needed for the system to operate is stored.

• Hydraulic pump: An electric motor powers the pump to draw oil from the reservoir and push it into the pipeline at high pressure.

• Control valve: This is a very important component that helps control the flow and direction of the oil. It determines the speed and smoothness of the elevator's start-up and stop-up.

• Cylinder and Piston: Oil is pumped into the cylinder at high pressure, creating the thrust for the piston, allowing the elevator cabin to rise or fall.

• Control cabinet: This unit receives floor call signals from users to smoothly control the operating cycle of the motor, pump, and valve system.
