There are different parts in elevators, each of which has a specific task. Meanwhile, non-slip movement occurs with the hydraulic power unit. Due to the importance of this piece and its application, we want to continue to explain it, so stay with Scud Lift in the rest of the content.
What is the hydraulic elevator power unit?
The most important part of the hydraulic elevator is called the hydraulic power unit, whose task is to supply power, create and control the hydraulic flow. The electric motor rotates the pump with the help of electricity and the oil pump flows in the hydraulic circuit. The oil flow is controlled and adjusted with the help of the valve block and will be directed to the jack. In this way, with the movement of the jack, the elevator cabin moves up or down.
On the way down the cabin, with the movement command, the control valve is activated to move the oil inside the jack to the tank. For this reason, we can consider the control valve, pump and motor as the main parts of the power unit. We will talk more about these parts later. Other supporting parts of Powerunit include: oil tank, connections, hoses, vibration damper, noise reducer, tank valve, oil heater, electrical box, etc.

What are the most important parts of the hydraulic power unit?
As we mentioned above, the main and important parts of the hydraulic power unit include control valves, electric motor, hydraulic pump and oil tank. There are other parts that work in the hydraulic power unit, such as: return valves, manual pumps, pressure switches, manometers, pressure control valves, blocking valves, etc.
In the following, we would like to introduce the most important parts of the hydraulic power unit.
Hydraulic elevator control valve block
The control valve plays the main role in adjusting and adjusting the oil flow in two directions, entering the jack and leaving it to raise and lower the elevator cabin. The output flow rate of the pump is constant, that’s why the presence of a control valve is necessary for the smooth start of the movement, gentle acceleration to reach the maximum speed, movement at the maximum speed, deceleration until reaching the leveling speed (slow speed) and slow stop of the elevator for the power unit. be
If there is no proper control valve, when the elevator cabin starts moving, it will be launched like a rocket, and when it stops, the passengers inside the cabin will feel an earthquake-like state due to the sudden impact. Scud lift power units with excellent and appropriate quality will prevent any danger and provide a smooth and gentle movement for the elevator.
• Screw pump
The screw pump is another important part in the hydraulic power unit. Compared to gear pumps, these types of pumps provide smooth and uniform flow and have little noise.
• Electric motor inside the oil
Among the best electric motors that are used in the power unit of hydraulic elevators are submerged electric motors (in oil). This electric motor model is used in hydraulic power units of Scud Lift.
• oil tank
Another important part of the hydraulic power unit is the oil tank or the body of the power unit, where all parts and equipment are installed inside or on it. This part is produced with iron sheets with appropriate thicknesses and they are precisely cut and bent. The holes of the oil ducts and the connections corresponding to the control valves and other accessories are modeled and done with the help of the laser machine with great precision. After welding, leak test is done and finally it is ready to use with electrostatic paint coating.
The design of this part is done in such a way that the air flow passes through it and naturally cools the hydraulic oil. In addition, the opening and closing of the tank door is easy and the connections related to the motor base can be changed and adjusted. The oil tank is equipped with a tank lid for oil charging, engine vibration damper, shock absorber and standard hydraulic connections. Scud lift with the proper design of this part increases work efficiency and increases the life of the power unit.
Here we mentioned 4 of the most important components of the hydraulic power unit. You can contact us for more information.
Important points that you should keep in mind when buying a hydraulic power unit.
When buying any type of device, you should pay attention to a series of important points so that you can make a safe and suitable purchase. To buy a hydraulic power unit, you must pay attention to the important points that we mention below.
• Checking the type and performance of hydraulic power unit components
The most important point for buying a hydraulic power unit is to pay attention to the type and performance of its components. You should ask the manufacturer for detailed information about the parts, such as their type, size, and size, so that you can buy parts that fit and harmonize with each other.
• Attention to the originality of parts
Another important point is to make sure that the parts are original and avoid buying fake parts because they do not have the necessary quality and will cause you problems in the future. The use of fake and non-original parts greatly reduces the quality of elevator movement and can cost you a lot in the long run.
• Availability of parts
You must make sure that you have the parts and spare parts you need available so that you do not face problems during the maintenance and repair of the elevator power unit.
By considering these points, you can buy a quality hydraulic power unit and experience a slip-free movement in the elevator of your choice. You can get other necessary tips and guidance from our experts at Scud Lift and order the equipment and parts needed for the hydraulic power unit from our company.
