Leaks generally rank number one in the list of most common maintenance issues with hydraulic equipment. And leaking hydraulic connections are often accepted as an inherent characteristic of hydraulic machines. While this may have been true 40 years ago, advances in sealing technology and the development of reliable connection systems means that today, leak-free hydraulic systems are very much achievable.
Reliable Connections. Ideally, leak-free reliability begins at the design stage, when the type of hydraulic connection is selected for port, tube-end and hose-end connections.
Ports – Connectors that incorporate an elastomeric seal such as UN-O-Ring, BSPP and SAE 4-bolt flange offer the highest seal reliability.… continue reading »
The price of oil sure is defying gravity at the moment. But unless you’re the owner of a lot of poorly maintained (read: leaky) hydraulic equipment, the price of gas and diesel is likely hurting your wallet more than the price of hydraulic oil. Regardless, you sure don’t want to be shelling out for any more of it than you have to.
Ed Bailey, Bison Steel Inc., got and read The Hydraulic Maintenance Handbook and used the know-how within to deal with water contamination in a hydraulic shear. The oil capacity of the hydraulic tank was 300 gallons (1136 litres).
