Ship Watertight Door Hydraulic Cylinder

Ship Watertight Door Hydraulic Cylinder

Description

Ship watertight door hydraulic cylinder uses seamless tube, selects different tube thickness according to work pressure, the cylinder has the feature of high precision of bore size, light weight, simple structure, various connection method, constant low speed and stable cushioning function, normal work pressure 7~ 14Mpa, widely used for machine, light industry textile, plastic injection agriculture machine.

Main Parts of Hydraulic Cylinder

1. Cylinder barrel

The main function of the cylinder body is to hold cylinder pressure. The cylinder barrel is mostly made from a seamless tube. The cylinder barrel is ground and honed internally with a typical surface finish of 4 to 16 microinch. The piston reciprocates in the cylinder.

2. Cylinder head

The main function of the head is to enclose the pressure chamber from the other end. The head contains an integrated rod sealing arrangement or the option to accept a seal gland. The head is connected to the body by means of threading, bolts, or tie rod. A static seal is used in between head and barrel.

3. Cylinder base or cap

The main function of the cap is to enclose the pressure chamber at one end. The cap is connected to the body by means of welding, threading, bolts, or tie rod. Caps also perform as cylinder mounting components. Cap size is determined based on the bending stress. A static seal is used in between cap and barrel (except welded construction).

4. Piston

The main function of the piston is to separate the pressure zones inside the barrel. The piston is machined with grooves to fit elastomeric or metal seals and bearing elements. These seals can be single acting or double acting. The difference in pressure between the two sides of the piston causes the cylinder to extend and retract. The piston is attached with the piston rod by means of threads, bolts, or nuts to transfer the linear motion.
