TC Middle Trunnion Type Light Rod Hydraulic Cylinder Parameter:

TC Middle Trunnion Type Light Rod Hydraulic Cylinder Usage Method:

Installation: Select an appropriate installation position based on application requirements. Ensure that the middle trunnons are aligned with the load and system requirements. Secure the cylinder using the recommended bolts and ensure proper alignment for the best performance.

Hydraulic Connection: Connect the hydraulic hose to the cylinder to ensure a tight connection without leakage. During installation, follow the manufacturer’s torque specification guidelines to maintain the integrity of the hydraulic system.

System Integration: The cylinder is integrated into the hydraulic system and aligned with other components according to system requirements. Refer to the manufacturer’s guidelines and system schematics for proper installation.

Operation: Hydraulic pressure is applied to the system while adhering to industry standard safety protocols. The TC cylinder features an intermediate trunnion design that effectively converts liquid pressure into precise linear motion, providing reliable control for various applications.

TC Middle Trunnion Type Light Rod Hydraulic Cylinder Maintenance:

Regular maintenance is essential to ensure the longevity and optimal performance of the TC Middle trunnion-type light rod hydraulic cylinder. Consider the following maintenance guidelines:

  • Visual Inspection: Check the cylinder regularly for signs of leakage, damage, or wear. Pay close attention to the overall condition of seals, bearings, and cylinders. Replace worn or damaged parts promptly.
  • Lubrication: Follow the manufacturer’s recommendations for lubrication intervals and use appropriate lubricants. Proper lubrication minimizes friction, reduces wear, and ensures smooth operation.
  • Cleaning: Clean cylinders by removing dirt, debris, and contaminants. Use a non-abrasive cleaning agent and not use too much force during cleaning to avoid damaging vital components.
  • Seal Inspection: Check seals regularly for leakage or deterioration. Replace worn or damaged seals to maintain optimal performance and prevent potential system failures.
  • System Calibration: Periodically check cylinder performance, stroke length, speed, and accuracy. The system is calibrated as necessary to ensure accurate and consistent operation.

How To Bleed A Hydraulic Cylinder Without Bleeder Valve?

Bleeding a light rod hydraulic cylinder without a bleeder valve can be more challenging, but it is still possible. Here’s a step-by-step guide on how to bleed a hydraulic cylinder without a bleeder valve:

  1. Prepare the Necessary Tools: Before starting the bleeding process, gather the following tools: a wrench or socket set, a container to catch hydraulic fluid, and a clean cloth or rag.
  2. Position the Cylinder: Ensure that the hydraulic cylinder is safe and stable. Use clamps or fixtures to secure it and prevent accidental movement during bleeding if necessary.
  3. Locate the Highest Point: Identify the highest point on the hydraulic cylinder. This is the point where air tends to accumulate. It is usually near the cylinder’s end or the piston rod’s top.
  4. Loosen the Fittings: Using a wrench or socket set, carefully loosen the fitting or connection at the highest point of the cylinder. Ensure that the fitting is only loosened enough to allow air to escape and not to cause hydraulic fluid leakage.
  5. Slowly Extend the Cylinder: Activate the hydraulic system to extend the cylinder slowly. This action helps push the air bubbles towards the open fitting and allows them to escape.
  6. Monitor Fluid Flow: Pay close attention to the hydraulic fluid flow as the cylinder extends. Look for any air bubbles or foam in the fluid. Allow the liquid to flow until you observe a consistent and smooth flow without air bubbles.
  7. Tighten the Fitting: When confident that all the air has been bled from the cylinder, carefully tighten the fitting or connection at the highest point. Make sure it is adequately secured to prevent any hydraulic fluid leakage.
  8. Repeat the Process: If multiple cylinders exist in the hydraulic system or other high points where air might have collected, repeat steps 4 to 7 for each cylinder or high end.
  9. Check for Proper Operation: After bleeding the cylinder, test its operation to ensure it functions correctly. Activate the hydraulic system and observe the cylinder’s movement for irregularities or air-related issues. If any problems persist, consider contacting a hydraulic system professional for further assistance.
