One of the most common users of hydraulic systems is to move heavy objects because it is easy to obtain several times by changing the level of force. I think we all have the experience of squeezing the head of the water hose and increasing the tremendous force that the water comes out.
1. Hydraulic Elevator Heart Paurionite
Pavrionite is composed of three main components, whose task is to create the required pressure and transfer it to the cabin to move the elevator.
The main components of Paurionate
Motor: The electric motor starts rotating when connected to the electricity. Pump: inside the oil, the pump is coupled to the engine and causes the oil to come out with pressure. Group of valves: High pressure oil is controlled and directed by the group of valves to the piston of the jack on which the elevator cabin is mounted. The considerable force created causes the cabin to move upwards.
Paurionite lateral components
Oil resistor: (oil heating element)
It is a heater that automatically keeps the oil temperature above 15 degrees.
It is very necessary for the system in cold regions and early morning starts.
Cooling system:
In high-traffic buildings, the continuous start of the elevator causes an increase in the temperature of the oil and a decrease in its concentration, and inaccuracy in the start and stop of the elevator. In these cases, it is necessary to use a cooling system.
Emergency solenoid valve:
Emergency solenoid valve: This valve, which is usually connected to the battery circuit in the elevator board, makes it possible to return the oil to the tank by the battery and guide the elevator down in case of power failure.
pressure switches:
Two pressure sensors are used to control the maximum and minimum pressure of the power unit.
oil thermostat oil thermostat:
When the oil temperature increases too much, this feedback sensor informs the control system to stop the elevator until the oil cools down.
2. Hydraulic jacks hydraulic jack
The jack is the mediator between the elevator cabin and the oil tank, so that the increase in pressure in the power unit enters the jack piston in a controlled manner through the group of valves and pushes it upwards, as a result, the cabin starts to move.

Types of jack
Simple jacks: whose structure is 1 stage (single stage) and are the most common in the industry, directly and indirectly to the cabin The elevator is connected.
Telescopic jacks: When the length of the path is long, the size of the jack increases and transportation and handling become difficult, therefore, telescopic jacks that are inserted into each other as radio antennas are used, 2-stage, 3-stage telescopic jacks. 4 stages are produced and the more stages they have, the more expensive they are.
1. Car Slings (Car Frames) carceling
They are a frame made of steel sheet on which the cabin room (car) is mounted and moves on the guide rails by the tap shoes.
Carslings are equipped with shoe and roller parachutes and must have sufficient strength.
1. Common components in hydraulic and tensile elevators
The main difference is that a hydraulic elevator uses a hydraulic jack and power unit to raise and lower the elevator car, while a traction elevator uses a gearbox or gearless motor with a counterweight to control the movement of the car. slow However, some components of the hydraulic and traction elevator system are the same, such as the cabin, rails, cabin and floor doors, motor and door mechanism, control panel and elevator control panels.
Common elevator parts in hydraulic and traction elevators:
elevator cabin
Floor doors and cabin doors
Steel guide rails
Control panel
Command and summon chassis
As a result, the components and parts of the hydraulic lift consist of two main parts: hydraulic jack (piston, cylinder, shaft, etc.) and power unit (including oil tank, motor, pump, valves, etc.). And some parts are the same in hydraulic and traction elevators, such as: cabin, door, steering panel and rail.
