Dry Running Pumps: What is it and Why is it Harmful?
August 18th, 2019Hydraulic oils transmit and amplify actuator-controlled forces. They deliver those kinetic energies to mobile vehicle pistons and crane booms. In addition to that principal function, the fluid also cools and lubricates the fast-moving machine assemblies inside a hydraulic system. Hydraulic pumps, because they’re participants in this balanced fluid conveyance process, should never run dry. Regrettably, […]
Criteria for Hydraulic Filter Selection
August 4th, 2019When choosing a hydraulic filter, the fluid sieving architecture is expected to satisfy a long list of performance requirements. There’s a brief pause while product parameters are pored over. With all possible selection criteria reservations finally settled, the contamination blocking component is installed. Two separate system stages have been reviewed during this process. First came […]
The Importance of Oil Coolers in Hydraulic Systems
July 15th, 2019Whenever possible, complex hydraulic systems utilize hassle-free support systems. Take oil coolers, which are designed to prevent hydraulic fluids from overheating. While it’s true that cleverly engineered parts and superbly fabricated mechanisms help keep system oils temperature-controlled, such impeccably designed assemblies come with high price tags attached. Taking the route that doesn’t incur such high […]
Understanding the Functions of Manifold Valves in Hydraulic Systems
July 3rd, 2019Whatever the circuit type, be it electrical or hydraulic, the interconnecting lines in that circuit can’t work without control elements. Switches and transistors take up this duty in voltage-regulated circuits. In hydraulic/pneumatic applications, valves take their place. This is fluid control technology, not electric current, but the ruling principles are similar. For valves, pressures and […]
Understanding Pressure Compensation in Hydraulic Systems
June 19th, 2019Pressure compensation systems operate a little like feedback-based electronic systems. That’s not exactly a surprise, not when hydraulics circuits can become every bit as complex as any electronically based wiring. At any rate, the similarities are there for everyone to observe. When an output change occurs, a fraction of that change is sent back to […]
