Different ways to connect the piston cylinder head structure and its assembly process are different.

Different ways to connect the piston cylinder head structure and its assembly process are differentflanged cylinder. When the cylinder bore hole chamfer at the end without eating bumps, piston surface has been coated with  Hydraulic adapters oil, and concentric with the piston inside the cylinder bore, the piston assembly can be loaded. Head static sealing incision should be coated backing grease or industrial vaseline, and to ensure that the backing does not pop dislocation, according to the specified torque and evenly symmetrical sturdy cylinder head bolts.Neckar-bonded head. When assembling the cylinder bore surface of the card must be filled keyway, round cylinder bore surface to ensure no card group, piston seal is not damaged, commonly used in two waysFactory jobs or in the case of conditions should be processed three snap ring, with its filled card keyway, the piston and the cylinder head to be guided into the cylinder barrel after the suit, and then three snap ring out, and then load the card key. Needed to be reset before loading the guide sleeve head positioning ring, retainer and other pieces.Or no processing at the construction site conditions, asbestos can cut a strip (width keyways and the card), with its groove fill card are the same as described above. This method is fast, convenient, and can guarantee the quality of  threaded connection head. Since the cylinder bore is internally threaded end easy on the seal damage, it must be processed when assembling a thin opening guide sleeve, with its fixed on the piston head, the piston inside the cylinder into a smooth, both to protect the seal pieces, but also improve the quality of assembly Generally: Just follow the above process seriously seals and hydraulic cylinder assembly, you can make the hydraulic cylinder seal failure due to greatly reduce the frequency to ensure reliable operation of construction machinery.
