A. When refueling the hydraulic system, it is essential to filter and fill the hydraulic oil properly. The refueling tools must be thoroughly cleaned to avoid contamination. It is important not to remove the filter at the tank filler port in an attempt to speed up the process, as this can introduce contaminants into the system. Personnel involved in refueling should wear clean gloves and work clothes to prevent solid particles and fibers from entering the oil.
B. During dismantling, carefully remove the hydraulic oil tank cover, filter cover, test port, and hydraulic hoses, ensuring that dust does not enter the exposed oil channels. The work area must be completely clean before opening any components. Before removing the tank cap, clean the surrounding area. After unscrewing the cap, check and remove any debris that may have accumulated in the joint—never use water to flush the area, as this could allow moisture to enter the tank. Ensure the cap opens smoothly after cleaning. If wiping materials or hammers are needed, choose those that do not shed fibers and use hammers with rubber-coated striking surfaces. All hydraulic components and hoses should be carefully cleaned before assembly using high-pressure air. Always install genuine, well-packaged filter cartridges; even if the cartridge appears intact, a damaged internal package may mean it is not clean. Clean the filter during oil changes and wipe the inside of the filter housing with a suitable cloth before installing the new element.
C. For hydraulic system cleaning, only use the same type of hydraulic oil that is currently in the system. Maintain the oil temperature between 45°C and 80°C to ensure effective cleaning. Use a high flow rate to remove as many impurities as possible from the system. The system must be cleaned at least three times. After each cleaning, drain all the hot oil from the system. Once the cleaning process is complete, inspect and clean the filter, then replace it with a new one. This ensures the system remains free of contaminants and operates efficiently.
Concertina Barbed Wire
Concertina Barbed Wire, also known as Razor Wire, is a type of barbed wire that is formed in large coils which can be expanded like a concertina. It is designed with sharp edges or points arranged at intervals along the strand(s). This type of wire is used to form barriers or fences for security purposes, often used in military or prison settings.
The concertina design allows the wire to be compacted during storage and transport, and then expanded and installed with ease. It is highly effective as a deterrent and physical barrier due to its sharp blades which can cause serious injury to those trying to cross it. It is often used in combination with other types of fencing to create a high level of security.
Concertina wire is a type of barbed wire or razor wire that is formed in large coils which can be expanded like a concertina. It is used to form military-style wire obstacles.
1. Concertina Barbed Wire: This is a type of barbed wire that is coiled and can be expanded like a concertina. It is designed to create an obstacle that is difficult to overcome. It is often used in military settings or for high-security areas.
2. Concertina Razor Wire: This is similar to barbed wire but has razor-sharp blades instead of barbs. It is designed to cause serious harm to anyone trying to climb over or through it.
3. Concertina Wire Fencing: This is a type of fencing that uses concertina wire. It is often used for security purposes, particularly in prisons, military bases, and other high-risk areas.
4. Concertina Wire: This is a general term that can refer to either concertina barbed wire or concertina razor wire. It is named for its ability to be expanded and contracted like a concertina, which makes it easy to transport and install.
