How to Avoid Dieseling in Hydraulic Cylinders

Dieseling is a standard drawback in hydraulic cylinders that can behave as an actual killer to your system. This happens as air is entrained into the high-pressure fluid and creates a flammable mixture that would ignite upon contact with any of the hot surfaces in the cylinder. This ignition can cause high parts attrition on your hydraulic cylinders and in some cases lead to catastrophic failures if not repaired. In order to avoid severe dieseling and maximize the functionality of your hydraulic system, it is important for you to start implementing effective prevention techniques.

Hydraulic System: Basic Theory

To be able to prevent dieseling from your hydraulic cylinders the proper way, you must understand at least a bit of how these systems work. A hydraulic system operates through the use of fluid (liquids) which act as a channel to convey power from one point to another. The pump pressurizes the fluid and pushes it through hydraulic lines a actuator such as a cylinder to convert pressure into mechanical force. The actuator is what moves everything and this includes exerting force to move loads, or carry out mechanical work.

Diesel is the form of combustion that happens when there is a ton of air trapped in with liquid and gets compressed to high pressures, leaving combustibles behind. This compressed air can ignite and cause extensive damage when it hits the hot surfaces within the cylinder.

How to recognize and avoid hydraulic cylinder dieseling

This is due to the contamination of fluid which is one of the principal factors causing dieseling in hydraulic cylinder organs. Dirt, debris and other particles can seep into the hydraulic system as a result of which air is trapped within fluid. To avoid this risk, it is essential to you clean fluid and also keep proper filtration practices.

Elevated Fluid Temperature: High fluid temperatures can also be a cause of dieseling in hydraulic cylinders. Thus, dieseling is much more likely if the fluid temperature exceeds the flash point of oil. This is to prevent a situation like this by keeping your hydraulic system properly cooled and using fluids that can stand up to high temperatures.

Some Common Causes of Dieseling in Hydraulic Cylinders : High System Pressure - The most common source leading to dieseling is over-pressuring the system. Dieseling occurs when the system pressure gets too high that air becomes trapped in the fluid. To avoid this problem, make sure that your hydraulic system has the appropriate design and installation required to withstand these pressure levels.

Air leakage Air leakages inside hydraulic system can also cause dieseling in the cylinders As ambient air worms its way into the system, it's compressed and eventually bubbles right out with rest of our new explosive mixture. Carefully seal and maintain all fittings, connections on your hydraulic system to avoid this from happening.

Clean Fluid: To reduce the potential for dieseling, use clean fluid and avoid contamination through routine filter replacement. Keep the fluid fresh and check for contamination periodically.

Keep It Cool-Diesel fueling results from insufficient system cooling. Use an outside warm exchanger or perhaps cool liquid loop your complete system.

Maintain System Pressure: Always ensure that the pressure of your hydraulic system is kept within optimal levels. Too much pressure can cause air to be locked in the system causing dieseling.

This ensures that you find and secure all hydraulic fittings & connections to help prevent dieseling. Check for leaks and remedy promptly.

Do not diele: This is the point where if theres air trapped in the system even after clearing it with a hydraulic reservoir. Make sure the reservoir has enough air and is sized for your system.

4) Install Check Valves: Keep air from sneaking back into your hydraulic system by placing check valves at strategic points. These valves help to avoid air infiltration and possible problems.

Use Anti-Foaming Additives: Use the anti-foaming additives as per installation instructions in order to prevent air from being trapped inside of your hydraulic fluid which will consequently stop dieseling.

Routine System Checks: Maintaining a hydraulic system is no easy job, you need to constantly check if your machine works just fine or it needs some corrective maintenance. Inspect for leaks and all fluid levels, quality of fluids; confirm installation or replacement wear parts according to manufacturer specifications/reset reminder lineup.

Guidance from Hydraulic Cylinder and Dieseling Pros

Regular Maintenance: Hydraulic cylinder dieseling can be prevented by maintaining them correctly. Perform regular inspections, and correct any issues as early on to avoid more expensive problems down the line.

Best type of Lubrication: Right lubricant is vital for improved performance from your hydraulic cylinders. Use lubricant of the appropriate type and amount for your system, ensuring it is applied properly.

Cleanliness:** Keeping your hydraulic system clean is vital to the life of it, suppressing foreign debris. Filters can be blocked by debris and dirt leading to leaks as well dieseling in your cylinders.

Upgrade Your Hydraulic System Pumps, Valves and Cylinders: Upgrading to improved hydraulic system components will lead to a boost in your hydraulic system then this would improve the production. We say this because all we have seen these days are upgrades on the drawing board were not even something identified and studied by some hydraulic experts to determined how it would fall in accordance with your system.

To wrap up, dieseling in hydraulic cylinders is something you do not want your system to suffer from. By practising these proven prevention techniques, learning about hydraulic system basics with your power unit supplier and carefully looking after the upkeep of your hydraulics you can help prevent dieseling thus ensuring that it continues to run smoothly.
