Twin hydraulic cylinder on agricultural equipment. Will they work as you hoped? There are a few ways of controlling multiple cylinders in different applications. If you simply connect them up, there is every chance they won’t work or not as expected. Before jumping directly to flow dividers and position sensors, is there a simpler [...]
How do I pressure test my composite overwrapped pressure vessels or COPV? Can a Micropac® PTR-A programmable hydrostatic pressure cycle tester provide effective testing at low cost? Composites have been a massive growth area in the last few decades. Some applications are designing and manufacturing massively strong structures at a low mass that was [...]
Why are composites the future for so many pressure vessels? Composite pressure vessels can offer such enormous benefits over metallic pressure vessels. There is some serious engineering in them. Why are composites so successful for the right application? Think composite and focus on strength, low mass and freedom from corrosion. Composites have brought to [...]
Why is “country of smelting” suddenly so important? Smelting produces the raw material billet for steel or aluminium for further processing. Steel is shown. A rolling mill or extrusion press will produce the material that your material supplier buys. A steel rolling mill is shown. Why you need [...]
When do I have to use a double acting hydraulic cylinder and why? Sometimes, a double acting hydraulic cylinder circuit is the only way to achieve your requirements. What are basic design considerations? Single versus double acting cylinders. Sometimes your design needs push and pull. The single acting configuration is left and double [...]
How do you use a single acting hydraulic cylinder cheaply, effectively and safely? We are fans of single acting hydraulic cylinders if they work for your application. Read how. We would always start by asking whether we can use a single acting cylinder. Without a doubt, there are key reasons for using one if [...]
Four decades of experience have told us what is important to customers. For Professionals specifying hydraulic equipment, hand pumps are important. It must be reliable in an emergency, capable of handling specific fluids, and resistant to your operating environment. Let’s run through the design philosophy on a Micropac pump. Why do we recommend the [...]
High quality potable water from the tap is something we take for granted. Lots of people in the world don’t have this luxury. Image thanks to CV Water Consultancy. What is potable water and what should a designer know about working with it? What is potable water? Potable water is drinking water suitable for [...]
Why was the Tangye Hydrapak such a great concept hydraulic hand pump and why have today’s Hydrapak, HMP, MHX and PSP hand pumps all evolved that original design so well? An old Hydrapak product brochure. The Tangye Hydrapak was the original pump back in the 1960’s. It was a trailblazer. That classic unit [...]
Our Micropac MW pumps are often piped into systems rather than supplied on a reservoir with suction tube already in place. What suction tube is right, which is wrong, and how long can a suction tube be? This is a basic question, but not commonly asked. Maybe hydraulic engineers get on with it from [...]
