Hydraulic Cylinder Seals Failure ben lee
We investigate the main reasons hydraulic cylinder seal failure including degradation from heat and incorrect material usage.

How do I interpret DC motor performance curves? ben lee
DC motor selection understanding the duty required by the application, comparing to the performance of each motor-pump. Two main performance graphs, Motor-pump, Motor Ratings.

What oil reservoir size should I specify ? ben lee
The widespread use of the “three times flow” rule of thumb serves well but current pressures on space, economics and environmental issues warrant a closer examination of this rule.

Do I need a Hydraulic Cooler for my power pack? ben lee
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.

Which battery cable size should I use? ben lee
When connecting a DC hydraulic power pack to the battery it is important to get the cable sizing correct. The battery cable will carry high currents and they must be sized to minimise voltage drops. When a DC powerpack is running at full load currents up to 300 amps can be required.

Which Hydraulic Oil should I use in my power pack? ben lee
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.

What Power Pack is right for me? ben lee
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 there are several pointers that will narrow down this range.

Hydraulic Power-Pack Basic ben lee
Primary drive sources could be direct current from a vehicle battery (DC),alternating current ( AC) from single or 3 phase motor, internal combustion engine or an air motor. These dictate the hydraulic power delivered to the oil and therefore control the flow and pressure limits.
