Use the correct method to install and remove the ferrule joint to avoid mechanical damage to the ferrule joint. When hoisting the ferrule joint, the lifting belt cannot be tied to the ferrule joint rod or the actuator for hoisting, otherwise the ferrule joint rod will be bent, the ferrule joint diameter seal will fail, and the gearbox will be damaged; Simple blind plates are installed at both ends of the ferrule joint to prevent water, sand and other impurities from entering the ferrule joint cavity during transportation and on the construction site, causing corrosion and damage to the seal; on the construction site, the ferrule joints are neatly placed On the sleepers, do not place them anywhere to avoid damage or breakage of the drain nozzles and grease nozzles. Before installation, the ferrule joints must be lubricated with grease. On the one hand, check whether the grease injection channel is unobstructed by injecting grease, and on the other hand, fill the sealing surface and rear cavity of the ferrule type joint seat to prevent impurities from entering the sealing surface and the rear cavity, and at the same time, it can reduce the impact of welding high temperature on the ferrule joint seat. During the whole process of installation, keep the ferrule joint in the fully open position; when the welding is completed, the water pressure test is completed, and before and after each operation, the grease must be replenished in time; after the water pressure test is completed, the The water in the ferrule joint cavity is drained in time to prevent corrosion and freezing.
