drukcilinders

Drukcilinders is a Dutch term with two main meanings, depending on the context. In hydraulics and pneumatics, a drukcilinder (pressure cylinder) is a device that converts fluid pressure into linear motion. It consists of a cylinder barrel, a piston with a rod, seals, and end caps, with ports for fluid entry and exit. They can be single-acting, using pressure on one side, or double-acting, using pressure on both sides to create movement. Variants include telescopic and welded or tie-rod designs. Operating pressures, bore size, and stroke length determine the force and displacement produced. Materials commonly used are steel, stainless steel, or aluminium. Applications include industrial automation, clamping, lifting, and actuation in machinery. Maintenance focuses on seals, lubrication, leak prevention, and proper alignment and mounting.

In printing technology, drukcilinders refer to the cylinders that carry ink and transfer it to the substrate in a press. In offset printing, there are several types: plate cylinders, which hold the printing plate; blanket cylinders, which transfer ink from the plate to a rubber blanket; and impression cylinders, which press the paper against the blanket to receive the ink. The term can also apply to other printing systems where cylindrical components are involved in ink transfer. Key considerations for printing cylinders include surface finish, wear resistance, precise alignment, and compatibility with ink viscosity and dampening systems.

Overall, the meaning of drukcilinders depends on the industry. In engineering, it denotes a pressure-driven actuator, while in printing, it denotes cylinders involved in ink transfer.
