Compact and Powerful Hydraulic Actuators

As the name suggests, the hydraulic power unit, based on Pascal’s law of dynamics is the main driving component in a hydraulic system. It consists of a motor, a reservoir and a hydraulic pump. Their synchronised action even in a mini hydraulic power unit generates ample power to stir up motion and drive the hydraulic ram. This space saving vertical style device is designed for quiet and leak-free operation.

These power units generate power as per the pressure exerted on a specific area. With a wide range of applications, these are designed depending on the ultimate utility and manufactured. To illustrate this aspect, the Delhi NCR based Dantal Hydraulics is one of the leading Indian companies engaged in the development and fabrication of such silent and leak-free operation power units. Apart from customised applications, the Mini Compact Power Packs produced by this company are extensively used in systems like – Read more

Components & Specifications of Hydraulic Cylinder

What are hydraulic cylinders?

A hydraulics cylinder is a mechanical actuator that generates force created by a compressed liquid locked in a cylindrical vessel. They are a variety of application of such cylinders as these are used in manufacturing machines, construction machines and garbage dump trucks. The fluid of these cylinders is an oil-based lubricant to facilitate the back and forth movement of the barrel. The barrel exerts pressure on the fluid generating force that is ten times greater than the force exerted on the fluid.

What are the different parts and variants of hydraulic cylinders?

A standard hydraulic cylinder can be broadly divided into three parts. First is the barrel itself, second is the base or the cap and lastly the end of the cylinder. The role of barrel is to keep the pressure of the cylinder intact. The further classification of the parts may be listed as piston, piston rod, and seal gland. The role of Piston is to maintain the back and forth movement inside the barrel, it also varies the pressure inside the barrel. The piston rod is a hard piece of chrome attached to the piston that is connected with the cylinder adjoining the end of the rod.

The seal gland is prefixed at the top of the cylinder and prevents leakage of the compressed oil keeping the pressure of the barrel as it is. A mini hydraulic power unit will include all these basic parts. Different types of cylinders employ the type of parts with different operating pressure. On the basis of the components and its specifications, the hydraulic cylinder is classified as Multistage, Telescopic, Ram and cable cylinders.
