The cleanliness of the oil plays a crucial role. In order to improve the cleanliness of the oil inside the lubricating pipeline after installation, it is necessary to control from the following aspects and strictly check:
Cold cutting methods, such as saw and cutting machine, are used to avoid the use of flame cutting. The cold cutting processing surface is smooth and the pipeline is clean, which can greatly reduce the possibility of impurities such as burr produced by the welding of the pipeline.
Pipeline welding, the pipeline welding method uses argon arc as the base, electric welding covering welding method, adopting this method has many advantages: argon arc welding because in the welding process constantly send argon gas, protect the welding material from the air oxygen contact, so as to prevent the oxidation of the welding material. In argon arc welding, proper welding wire, welding process parameters and good gas protection can make the root get good penetration, and the penetration is uniform, the surface is smooth and neat, and there are no defects such as welding nodulation, incomplete penetration and sag, which are easy to produce in general electrode arc welding. Because the weld does not produce welding slag, welding tumor and other impurities, greatly reduce the difficulty of later washing.
