Hydraulic oil water contamination poses a significant threat to the performance and longevity of hydraulic jacks.

Water can infiltrate hydraulic fluid through various sources, such as atmospheric humidity or improper storage practices, and its presence can have detrimental effects on the functionality of your equipment.

Several adverse consequences of water contamination to your hydraulic oil include:

Reduced Lubrication: Water contamination diminishes the lubricating properties of hydraulic fluid, leading to increased friction and wear on the moving components of the hydraulic jack.

Corrosion: Water contamination accelerates the oxidation process within the hydraulic system, compromising the structural integrity of hydraulic components.

Sludge Formation: Water contamination can cause the formation of sludge or emulsions within the hydraulic fluid, resulting in blockages and restrictions within the hydraulic system. Sludge buildup can impair the flow of hydraulic oil and inhibit the proper operation of the hydraulic jack.

2. Solving Contaminants Problems

To effectively manage and mitigate hydraulic oil contamination issues, here are solutions to address them:

2.1 Built-in Contaminants:

• Flushing: Before commissioning new hydraulic systems or installing new components, perform a thorough flush of the hydraulic system to remove built-in contaminants.

• Filtration: Install high-quality filtration systems to capture residual contaminants during operation and prevent them from circulating in the hydraulic fluid.

• Use of Clean Components: Source hydraulic components from reputable manufacturers that adhere to stringent cleanliness standards during production to minimise built-in contamination.

2.2 Generated Contaminants:

• Regular Maintenance: Implement a proactive maintenance schedule to monitor and address wear-related contamination issues promptly.

• Correct Fluid Selection: Ensure the use of the correct hydraulic fluid with appropriate viscosity and additives to minimise wear and abrasion.

• Component Inspection: Regularly inspect hydraulic components for signs of wear or damage that could contribute to generated contamination, and replace worn parts as necessary.

2.3 Air Contamination:

• Sealing: Seal hydraulic systems effectively to minimise air ingress during operation. Use seals and gaskets designed to withstand pressure differentials and prevent air leaks.

• System Design: Optimise hydraulic system design to minimise cavitation and aeration, which can introduce air into the hydraulic fluid.

2.4 Water Contamination:

• Storage Practices: Store hydraulic fluid in sealed containers in a clean, dry environment to prevent water ingress. Ensure containers are tightly sealed and protected from moisture.

• Desiccant Breathers: Install desiccant breathers on hydraulic reservoirs to remove moisture vapour from incoming air and prevent water contamination.

• Periodic Fluid Analysis: Conduct regular fluid analysis to detect water contamination early and take corrective action before it causes damage to hydraulic components.
