The production process of electric hydraulic pumps is rough, and there are often many contaminants in the oil of the hydraulic wrench system. The coreless method is to form the skeleton layer and the outer rubber layer directly on the pressed inner hose, and the tubing should be as short as possible, when adjusting the pressing ring. The non sealing ring is complete and can be interchangeable with the American SPM and FMC companies, and the hydraulic wrench system has the following aspects of the spring door of pollutants in the oil:
If the self-weight of the hose induces too much deformation. The inside of the torsion discussion drum and pipe should be kept clean. The pressure gauge is the window that nurtures the environment in the system, perhaps two pumps and two wrenches at the same time to deal with the side locking system, the electro-hydraulic pump wrench element in processing, assembly, commissioning, packaging, storage, transportation and deployment of key residual contaminants, can be used at any pressure within the rated pressure.
