1. The optimal operating viscosity for the working oil ranges between 29 to 74 mm²/s, with ISO VG46 anti-wear hydraulic oil being the recommended choice. The ideal working oil temperature spans from -20°C to 80°C. In cases where the ambient or operating temperatures are lower, it may be advisable to use oils of reduced viscosity, especially for larger oil cylinders.
2. The filtration system within the hydraulic setup must maintain a minimum accuracy of 80 microns. Strict measures must be taken to manage oil contamination, ensuring the oil remains pristine. Regular checks on oil performance are essential, along with periodic fine filtration processes and timely replacement of fresh working oil.
3. During assembly, ensure the piston rod's joint aligns correctly with the cylinder head, the ears (or intermediate pivot shaft). The entire piston rod should remain straight throughout its extension and retraction movements, preventing any rigid interference or unintended damage.
4. Once the large oil cylinder has been mounted onto the main machinery, operational testing should include a thorough inspection of the oil outlet pipe and guide sleeve for leaks. Additionally, lubrication of the bearing parts at the ear and intermediate hinge shaft is crucial.
5. In instances of oil leakage or other malfunctions, hydraulic pressure should be applied to shift the piston to one end of the cylinder before disassembly. Efforts should be made to avoid any improper hammering or sudden drops during this process.
6. Prior to disassembly, first, release the overflow valve to bring the hydraulic circuit pressure down to zero. Cut off the power supply and halt the hydraulic device’s operation. After loosening the oil port pipelines, block the ports using oil plugs.
7. Avoid using the piston rod as a grounding point to prevent electric shocks.

In addition to these technical guidelines, it’s also important to consider environmental factors when handling hydraulic systems. Extreme weather conditions can affect both the performance and lifespan of hydraulic components. Regular maintenance checks should not only focus on mechanical aspects but also consider how external conditions might impact the system. Furthermore, training operators thoroughly on best practices can significantly enhance safety and efficiency. Investing in high-quality materials and components is another way to ensure long-term reliability and performance.
Aluminum single hung window is a relatively new type of window. Here is a detailed introduction about it:
Structure and opening method:
Structure: Aluminum single hung window is mainly composed of aluminum alloy frame and window sash. Its frame structure is strong and can withstand large weight and pressure to ensure the stability and safety of the window.
Opening method: The window sash is opened and closed by pulling in the vertical direction. This opening method is different from traditional sliding windows or casement windows. It does not occupy the horizontal space indoors or outdoors and is particularly suitable for installation in locations with limited space, such as kitchens, bathrooms, narrow corridors, etc.
Advantages:
Good ventilation:Aluminum single hung windows can be opened to a large extent, so that indoor and outdoor air can circulate fully, effectively improving the indoor ventilation effect. In addition, some aluminum single hung windows can also realize multi-sash linkage to further increase the ventilation area.
Wide field of vision: Due to the particularity of its opening method, aluminum single hung windows will not be blocked by window frames like casement windows when opened, which can provide a wider field of vision and make the indoor space more transparent and bright.
High safety: When the window sash is closed, it fits tightly with the window frame, and with high-quality sealing strips, it can effectively prevent rain, dust, wind and sand from entering the room. At the same time, some aluminum single hung windows are also equipped with safety locks and other devices to enhance the anti-theft performance of the windows.
Easy to clean: The window sash can be tilted inward or outward, which is convenient for users to clean the inside and outside of the window, solving the problem of difficult cleaning of high-rise windows.
