At US Hydraulics, our focus on hydraulic systems, particularly hydraulic cylinder repair, is driven by industry needs and a commitment to quality service. A properly functioning hydraulic system improves construction, mining, or industrial performance. Here are ten steps we follow to diagnose issues in hydraulic systems before proceeding with repairs:

Visual Inspection

Begin the hydraulic cylinder repair process with a thorough visual inspection for any external signs of wear or damage. Check for misalignment, corrosion, or any evident physical damages that could affect the system’s operation. Identifying early signs of wear, damage, or contamination is key to maintaining the integrity of the hydraulic system and preventing further deterioration or potential failures. Our technicians utilize advanced tools like the Large Capacity Test Stand to keep your hydraulic cylinders in peak performance.

Listen for Unusual Noises

Hydraulic systems typically operate smoothly with little noise. Listen for abnormal sounds like knocking, grinding, or squeaking, indicating aeration or cavitation problems. 

Aeration in hydraulics can cause damage to many parts, including the pistons and the gears. It can also degrade the oil and hydraulic fluid. Diagnostic tools will allow technicians to find where the air is trapped to fix it.

When addressing cavitation due to insufficient fluid, we utilize the ProKing PA 50 lathe, which aids in precise identification and effective resolution. By finding where the issue lies, technicians can repair the hydraulics and add more fluid to the system.

Identify and Address Leaks

Inspect hydraulic systems for fluid leaks; external leaks often manifest as visible drips, whereas internal leaks might be less apparent. US Hydraulics uses diagnostic tools like high-pressure testing equipment and the ProKing PA 50 lathe to identify and address external and internal leaks, protecting your system from potential damage and providing optimal performance.

Check Hydraulic Fluid Quality

Evaluate the hydraulic fluid for signs of contamination or degradation. Contaminated fluid can cause overheating and system damage. Our team identifies contamination types like dirt, water, and chemical impurities. Each contamination type presents challenges, potentially leading to increased wear or system failure. We apply practical techniques, including system flushing, filtering, and fluid replacement, to manage these issues effectively and maintain your system’s optimal performance.

Assess Temperature and Overheating

Monitor the system’s temperature, as overheating can indicate issues like contaminated fluid, blockages, or mechanical faults. At US Hydraulics, our team uses multiple diagnostic methods and tools, such as thermal imaging cameras and temperature gauges, to identify the cause of overheating. This allows us to assess whether your hydraulic system operates within safe temperature ranges, typically below 180°F, preventing damage and maintaining efficiency.

Evaluate System Response

Test the system’s response time to identify issues with fluid levels, air bubbles, or worn components. Utilizing our Large Capacity Test Stand with 100-horsepower capability, US Hydraulics conducts precision testing to measure torque and system responsiveness. This testing identifies issues and guides us in applying corrective measures to enhance the system’s performance and reliability.

Inspect Motor Function

Inspect the hydraulic system for wear or malfunction that could impact its efficiency. US Hydraulics’ knowledge of single and multi-stage units, including hydrostatic drivers, pistons, vanes, gears, screw styles, and rotating groups, directly informs our motor function inspection process. Utilizing our 100-horsepower Test Bench, we measure torque, which diagnoses the performance of hydraulic components. This approach is fundamental to our hydraulic repair and maintenance services, making sure that each system operates effectively.

Review Valve Operation and Calibration

Valves can play a key role in controlling hydraulic systems. At US Hydraulics, our specialized tools, like the ProKing PA 50, allow us to check the calibration and test the valves. These tools facilitate accurate adjustments to allow valves to operate efficiently. By fixing the valves and calibration, we can enhance the functionality and reliability of your system.

Analyze System Pressure and Flow

Use a pressure gauge and a flow meter to assess your hydraulic system’s pressure and flow of hydraulic fluid. These tools help measure the hydraulic fluid’s force and rate of movement within the system. Consistent readings aligned with the system’s specifications indicate a healthy system. However, deviations from these norms can signal potential issues. Advanced diagnostic tools, including the 100 Horsepower Large Capacity Test Stand, can help us diagnose and address discrepancies in pressure and flow.

Consult With Hydraulic Experts

Addressing complex hydraulic challenges like system overloads, unusual noises, or persistent leaks requires specialized knowledge. US Hydraulics offers expertise in identifying and resolving these issues with advanced equipment. This equipment, including the Hydraulic Cylinder Repair Bench, enhances system performance and durability.
