Horses For Courses: When NOT To Reach For A Hydraulic Solution

hyd_dwgOne of our members who recently downloaded and read my “6 Costly Mistakes…” report, is contemplating a change from electro-mechanical drive to hydraulic:

“I am just starting to work with hydraulics and so I’m trying NOT to make mistake #8 (not getting an education in hydraulics). We are a small manufacturing company that produces honey extracting equipment, and we are looking to make our machinery quieter.

We use several linear actuators on our equipment which consist of instant reverse or gear motors and acme threaded rods. They have a lot of bearings that have a habit of making a lot continue reading »

Hydraulic Equipment Operating Costs: The Go-To-Guy vs The Bean Counter

hydraulic oil drumIn a previous blog post I discussed how being engaged and caring about what you’re doing often has a cost associated with it. The odd sleepless night and premature grayness come to mind. But if you think you’ve got more than your fair share hydraulic headaches, this story may put them into perspective:

“I am a maintenance planner at a large coal mine in Canada. I relate to most of the issues you discuss in each blog post. I truly believe that one has to treat hydraulic oil properly from the getgo and filter it to keep it clean while continue reading »

Hydraulic Control Response: How Fast Is ‘Fast’?

Hydraulic Solenoid Valve (Bosch Rexroth)At a seminar I attended on CAN-bus control systems (CAN is a protocol for the transmission and processing of control and sensor information over a ‘bus’ cable on automotive and mobile equipment) the presenter was asked:

“Because only one signal at a time can be sent over the bus, when used to control multiple, fast-response hydraulic valves, could the necessary prioritising and queueing of the control signals cause a delay in the response of the system?”

To this the presenter replied: “How fast is fast?” And considering fast is a relative term, it needed clarification. Indeed, when it comes to … continue reading »
