When checking the slide wire, check whether there is any looseness and disengagement at each joint of 6 meters. When checking the conductive device, check whether the movable part is flexible, whether the tension spring is fatigued, and the brush wears. These conditions above the trolley line will affect the conductive properties of the slide wire and the tracking performance of the conductive device. If problems occur, adjustments should be made in time.
During the renovation of holiday equipment, the conductive device is pulled out of the catheter and the brush roller of the conductive device is inspected for wear. If the brush is less than the specified effective length, it must be promptly replaced. When the guide roller is deformed seriously, it must be replaced to maintain the conductive device. Run normally and brush well and check the cause.
Safety slides In all parts, brushes are the only parts that normally wear out.
For severely corrosive gas environments, the corrosion of brackets, hangers, and retractors must be checked; and measures should be taken to apply anti-rust materials. Use the place where the trolley wire is used, such as when performing infrastructure. Do not impact, pressurize the power transmission conduits, or press the weights on the power transmission conduits.
Prevent deformation and cracking of power transmission conduits, affect their use, and cause safety accidents. After the infrastructure is completed, the infrastructure waste on the power transmission conduit should be immediately removed.
During normal maintenance, workers are not allowed to step on the power transmission conduit or its support to prevent damage to the flatness of the entire line and accidents.
Cementing Plug also called wiper plug is a rubber plug used to separate the drilling mud from other fluids. There are two types of cementing plugs, bottom plug and top plug. Non-rotating type and common type are two options for customers. We provide non-rotating type plugs that have locking teeth on both the top and bottom plugs and float collars, allowing the plugs to lock together during drill-out.
Conventional Bottom and Top Cementing Plug (Wiper Plug) is manufactured with graded rubber that is fused onto a composite or aluminum core. Top cementing plug can be used when a dual plug system is not required and bottom cementing plug can be used when a dual plug system is required.
