A. During refueling, the hydraulic oil must be filtered and properly filled. The refueling tools should be thoroughly cleaned to avoid contamination. It is not recommended to remove the filter at the tank filler port in an attempt to speed up the process, as this can introduce dirt and debris into the system. Personnel involved in refueling should wear clean gloves and work clothes to prevent solid or fiber contaminants from entering the oil. This ensures the integrity of the hydraulic system and prolongs its service life.
B. When disassembling components such as the hydraulic oil tank cover, filter cover, test port, and hydraulic lines, it's essential to protect the system from dust exposure. The dismantling area must be fully cleaned before opening any parts. Before removing the tank cap, clean the surrounding area to eliminate any dirt or debris. After unscrewing the cap, carefully remove any remaining particles from the joint—never use water for flushing, as it could lead to moisture entering the tank. Ensure that the cap opens smoothly after cleaning. If wiping materials or hammers are needed, choose those that do not shed fibers and use a hammer with a rubber-covered striking surface to avoid damaging components. All hydraulic parts and hoses should be thoroughly cleaned before being reassembled using high-pressure air. Always use genuine, well-packaged filter cartridges; even if the cartridge appears undamaged, a compromised inner packaging may mean it's not clean. Clean the filter during oil changes, and before installing a new filter element, wipe the inside of the filter housing with a suitable material to ensure no contaminants remain.
C. When cleaning the hydraulic system, always use the same type of hydraulic oil that is already in the system. The oil temperature should be maintained between 45°C and 80°C to ensure effective cleaning. A high flow rate is recommended to flush out as many impurities as possible. The system should be cleaned a minimum of three times. After each cleaning session, drain all the hot oil from the system. Once the cleaning is complete, inspect and clean the filter, then replace it with a new one. This thorough approach helps maintain the cleanliness and efficiency of the hydraulic system over time.
Welded Wire Mesh Fence
Welded WIRE MESH fence is a type of fencing made from steel wires arranged in a grid or mesh pattern. This type of fence is known for its strength and durability, making it an ideal choice for high-security areas. The wires are welded at each intersection to increase the fence's strength and resistance.
A welded wire fence, on the other hand, is a more general term that can refer to any fence made from welded wire, regardless of the specific pattern or design. This can include everything from simple garden fences to heavy-duty security fences.
PVC coated wire mesh is a type of welded wire fence that has been coated with a layer of polyvinyl chloride (PVC) for added durability and resistance to the elements. This coating can also give the fence a more attractive, finished look and can be available in a variety of colors.
Welded mesh fencing is a versatile and popular choice for both residential and commercial fencing applications. It is typically used for security, to keep out unwanted visitors, or to contain pets or livestock. The strength and durability of welded mesh make it a reliable choice for these applications, and its relatively low cost and easy installation make it a practical choice as well.
