Those elevators that are operated by oil pressure are called Jacky elevators or hydraulic elevators. In the domestic hydraulic elevator, the power unit and jack are responsible for providing the driving force. These elevators have simple and advanced types, whose simple examples consist of pistons and cylinders. These two pieces are installed exactly under the elevator cabin. After the engine rotates, the oil from inside the tank is pumped by the pump towards the elevator cylinder, and after its capacity is filled, the pressurized oil moves them up due to the force it exerts on the cabin and piston.
In general, the hydraulic lift is under the influence of the hydraulic jack and is moved by it. Of course, before the hydraulic jack, this liquid or oil is under pressure, which causes the lift cabin to rise. The word hydraulic means power generation, transmission and transformation by the same fluid under pressure. It is customary to use hydraulic elevators in many construction projects in Iran and around the world. Because the engine, pump, etc. are placed inside the machine room, such elevators do not need to install the engine room in the upper part of the shaft.
⭕️ Technical specifications of hydraulic elevator
It is natural to get detailed information about the technical specifications before implementing the hydraulic lift. Therefore, in this section, we provide you with information about the technical specifications of this type of elevator.
In general, this type of elevator has several simple parts, including the oil tank, control board, and power unit for pumping. When the movement command causes the elevator cabin to go up or down, the sensor data in this elevator determines the type of movement. Finally, adjusted forces are applied to the valves by the same data sensors that are located on each floor.
Finally, it is the liquid pressure inside the cylinders that moves the piston. Since the cabin is mounted on the piston, it moves and moves. The mechanism of hydraulic elevators is so simple, but their technical specifications are as follows.
How does a hydraulic lift (jack) work?
Hydraulic elevators are usually used in buildings that have less than 6 floors. When the elevator is going up, the motor inside the power unit rotates and transfers the oil from the tank to the cylinder. After the oil is pumped and the cylinder is filled, the jack piston is connected to the car sling due to pressure. It simply moves the elevator cabin upwards. To stop the elevator cabin on each floor, a message must be sent to the motor from the central system to prevent oil pumping.
After stopping the oil pumping, the elevator stops at each floor. In order to move the elevator car down, a message must be sent to the steering valves. The sent command opens the valve and the oil moves through the system. This causes gravity and the weight of the elevator cabin to transfer force to the elevator cylinder and jack. This is when the cylinder is emptied of oil.
For the elevator to stop moving and stop completely, an order must be issued from the central control system. This command causes the elevator valve to close and the cabin to stop.
