When Higher Hydraulic Pressure Means Higher Maintenance Costs

Hydraulic Pressure IncreaseIn most hydraulic applications there are essentially two ways to get the required power output: high flow at (relatively) low pressure; and low flow at high pressure. This is because power is a product of flow and pressure; increase pressure and you can reduce flow proportionately but still get the same power output. For example, 100 liters/min at 200 bar … Read more

6 Silent Killers of Hydraulic Machines

Hydraulic Maint Handbook

1. Abrasive wear is the scuffing and scoring of a lubricated surface. It can be further divided into two-body abrasion and three-body abrasion. Two-body abrasion occurs when two lubricated surfaces come into direct contact with each other–usually as a result of loss of the lubricating oil film. Three-body abrasion occurs when the clearance between two lubricated surfaces is bridged by … Read more

The Simple Test You Need To Do Before Switching Hydraulic Oils

hydraulic oil drumThe issues which can arise when switching brand and/or type of hydraulic oil, is a question I get a lot. And the crux of this problem, is:
1. You can never completely drain ALL of the original oil out of the hydraulic system; and therefore:
2. There WILL be some mixing of the original and the new oil, so how … Read more
