1. The recommended working oil viscosity ranges from 29 to 74 mm²/s, with ISO VG46 anti-wear hydraulic oil being the preferred choice. The ideal operating temperature for the working oil is between -20°C and 80°C. In situations where the ambient temperature or operational conditions are cold, lower viscosity oils may be employed in larger oil cylinders to ensure smooth operation.
2. The filtration system must maintain a precision level of at least 80 microns. It's crucial to consistently monitor and manage oil contamination, keeping the oil clean at all times. Regular performance checks and necessary fine filtration processes should be carried out, and old working oil should be replaced with fresh supplies when needed.
3. During installation, ensure the alignment of the piston rod joint with the cylinder head and the direction of the ears or intermediate hinge shafts. Straightness of the piston rod must be maintained throughout its movement to avoid rigid interference or unnecessary damage.
4. After installing the large oil cylinder on the main machinery, conduct operational tests to verify there are no leaks in the oil outlet pipe or the guide sleeve. Lubricate the bearing parts of the ears and the intermediate hinge shafts.
5. In the event of oil leakage or other malfunctions, apply hydraulic pressure to shift the piston to either end of the cylinder before disassembly. Efforts should be made to avoid rough handling such as knocking or sudden drops during this process.
6. Prior to disassembly, first loosen the relief valve to reduce hydraulic circuit pressure to zero. Disconnect the power supply and cease the operation of the hydraulic equipment. Once the oil port pipelines are loosened, block the ports using oil plugs.
7. Do not use the piston rod as a grounding point to prevent electric shock risks.

Aluminum alloy casement window is a common type of window with the following characteristics:
1. Structural characteristics
Frame
The frame is made of aluminum alloy profiles, which have the advantages of light weight, high strength and corrosion resistance. Its cross-sectional shape is diverse and can be selected according to different design requirements and stress conditions to ensure the stability of the window.
Opening method
The window sash is connected to the window frame through hinges and can be opened outward or inward. The outward opening type does not occupy indoor space and has a wide field of vision, but has higher requirements for the sealing and safety of the window; the inward opening type is convenient for cleaning the outside of the window, but it will occupy a certain amount of indoor space.
2. Performance characteristics
Good sealing
When the casement window is closed, the window sash fits tightly with the window frame, and with high-quality sealing strips, it can effectively prevent rain, dust and noise from entering the room. Its sealing performance is better than that of sliding windows, which can better maintain the indoor environmental quality.
Good ventilation
The opening angle can be adjusted according to needs to achieve good ventilation effect. Some casement windows can also be equipped with limit devices to control the opening angle to ensure safety while achieving ventilation.
Strong security
Hardware accessories such as hinges and locks can provide better security. If the outward-opening casement window adopts a multi-point lock system, it can effectively prevent the window sash from being pried open by external force; the inward-opening casement window is easy to operate indoors, and the safety can also be enhanced by adding guardrails.
3. Aesthetics and durability
Aesthetics
Aluminum alloy profiles can be subjected to a variety of surface treatments, such as anodizing, powder coating, fluorocarbon coating, etc., which can present different colors and textures, and can match various architectural styles to enhance the overall aesthetics of the building.
Durability
Aluminum alloy itself has good corrosion resistance and is not easy to rust. With proper maintenance, its service life is long. However, the quality of hardware accessories has a greater impact on the overall durability of the window. High-quality hardware accessories can ensure the long-term and stable use of the window.
