Heat-resistant hydraulic oil. If the temperature of oil is increased it has a lower viscosity, meaning the oil will flow easier. This increases the risk of leaking of the loss of the oil's properties. In the event that the system is exposed to high temperatures additives are added to the oil in order to maintain a viscosity suitable for the

Get a quoteOne cause of hot spots in the oil is microdieseling, which is the implosion of entrained air bubbles when the oil passes through a high-pressure pump in the hydraulic circuit. This creates a local oil temperature in excess of 1,000°C (more than 1,800°F), which releases more than enough heat to cause oil molecules to …
Get a quoteFeb 15, 2012 · The widely used rule of thumb is that for every 18 degrees F increase in temperature, the life of the oil is cut in half. Still, it is common for high temperatures to be recommended in paper mill applications. The reasons include better water-shedding ability, lower foaming tendency, better air release, improved particle settling rate, better drain back flows and more rapid vaporization of water.

Get a quotewhere ignition sources are present. When hydraulic oil is released under pressure, it often results in an atomized spray or mist of oil droplets that may extend as far as 10 m from the break (Bowen & Shirvill, 1994). The oil spray can be ignited readily by hot surfaces, such as heated or molten metal, electric heaters, open flames or welding arcs.

Get a quoteHydraulic fluid temperatures above 180°F (82°C) damage most seal compounds and accelerate degradation of the oil. While the operation of any hydraulic system at temperatures above 180°F should be avoided, fluid temperature is too high when viscosity falls below the optimum value for the hydraulic system's components.

Get a quoteJul 19, 2019 · The climate and the high ambient temperature of the operation cause the oil temperature to rise. The viscosity of the selected oil is wrong, the resistance of the viscosity is large, and the viscosity is too small, so the leakage will increase. In both cases, the temperature rise can be caused.
