Reduced downtime for hydraulics through the right fitting choice begins by the fitting's type, thread standard and fitting material with the operational pressure, the vibration profiles and fluid compatibility, not just fittings that fit the port. The majority of unplanned downtime in the hydraulic system trace back to leaks at fittings due to thread mismatches, improper tension, or fittings with a rating lower than the maximum system pressure. A careful selection process during both the designing and MRO stage can prevent the majority of these issues before they make it to the floor of the shop.

How to reduce hydraulic downtime through better fitting selection?
What is fluid power in a hydraulic system?
The term "fluid power" refers to the process that transmits and controls energy using a pressurized fluid that is typically hydraulic oil that is moving through a closed system of valves, pumps, hoses, and cylinders. In a hydraulic system fluid power transforms electrical energy to hydraulic power through the pump and then transforms it to mechanical energy via the actuator, which allows the small force input to create a greater output force.

Why do hydraulic systems overheat — And how can a heat exchanger fix it?
The system's temperature rises when heat produced by pressure drops friction, inefficiency, and friction (relief valve pump dumping, worn-out pumps, lines that are not sized correctly, or contamination of the fluid) outpaces the system's capability to dissipate the heat through the reservoir as well as ambient air.

Can hydraulic hose failures be predicted using sensors or condition monitoring?
Yes. Hydraulic hose problems can be identified with significant precision using a combination of pressure sensors as well as vibration analysis, temperature monitoring, and monitoring of fluid condition, especially when coupled with visual inspection of the cover and maintenance record.

How do you diagnose internal leakage in hydraulic motors?
Internal leakage within a hydraulic motor is detected by measuring the flow of the case drain at load, looking for the possibility of a decrease in output speed or torque at constant pressure, and then comparing volumetric efficiency with the benchmark of the manufacturer. A flow test of the case can be the best way to test for determining excessive flow that is returning to the tank via the drain line of the case
What is the ideal operating temperature for hydraulic fluid?
The optimal operating temperature for the majority of hydraulic fluids is between 100degF and 130°F (38degC between 54 and 38degC) and an upper safe limit of between 140degF and 160degF (60degC to 70degC) dependent on the type of fluid used and the seal materials employed. If you run below this temperature range, it causes an inefficient response and inadequate lubrication.

Varnish formation in hydraulic systems: causes and mitigation
The formation of varnish in hydraulic systems happens in the process of thermally degrading and oxidizing the molecules of hydraulic fluid, polymerizing to form sticky insoluble deposits that cling to the surfaces of internal components. In contrast to sludge, varnish forms an extremely thin, hard, lacquer-like layer that is formed in fluids that are clean and clear, which makes it difficult to discern by routine inspection of fluids. Varnish is deposited on spools of valves and orifices of servo valves along with bearings,
