What are some common causes of cylinder failure?

Side loading – Side loading is caused from the cylinder being misaligned which creates an unusual force on the piston rod. A side load of enough magnitude can result in tube scoring, piston rod and rod bearing wear, and seal failure. Contaminated Fluid – Contaminated fluid can cause premature rod seal failure. Abrasive particles in…

What is the difference between double acting and single acting cylinders?

Double-Acting – have a port at each end, supplied with hydraulic fluid for both the retraction and extension. Single-Acting – hydraulic fluid enters through a port at one end of the cylinder, which extends the rod by means of area difference. An external force or gravity returns the piston rod.

What Power Pack is right for me?

Hydraulic power units are used for a broad range of applications from operating control valves in the outback of Australia to raising parking barriers in Siberia. To match this range of applications there are an equally large range of hydraulic systems and products. Whether you are designing, specifying, manufacturing or purchasing a hydraulic power pack…

Which Hydraulic Oil should I use in my power pack?

There are a wide range of choices over an even wider range of budgets, but the right hydraulic oil will prolong your machine life and reduce your overall running costs.

Do I need a Hydraulic Cooler for my power pack?

A design decision to fit a hydraulic oil cooler like this can only be made with a full assessment of how much heat is going to be put into the oil and how much of that heat can the system dissipate without the oil overheating.

How does a variable displacement hydraulic pump work?

The displacement, or amount of fluid pumped per revolution of the pump’s input shaft can be varied while the pump is running. Many variable displacement pumps are “reversible”, meaning that they can act as a hydraulic motor and convert fluid energy into mechanical energy.

What is the function of the pump?

A pump produces liquid movement or flow: it does not generate pressure. It produces the flow necessary for the development of pressure which is a function of resistance to fluid flow in the system.

What is the hydraulic pump?

A hydraulic pump is a mechanical device that converts mechanical power into hydraulic energy. It generates flow with enough power to overcome pressure induced by the load.

How does a simple hydraulic system work?

The science behind hydraulics is called Pascal’s principle. Essentially, because the liquid in the pipe is incompressible, the pressure must stay constant all the way through it, even when you’re pushing it hard at one end or the other. Now pressure is defined as the force acting per unit of area.

What is the hydraulic motor?

A hydraulic motor is a mechanical actuator that converts hydraulic pressure and flow into torque and angular displacement (rotation). The hydraulic motor is the rotary counterpart of the hydraulic cylinder.
