FB Rear Flange Type Heavy Rod Hydraulic Cylinder Usage Method:

Mounting: First, securely install the FA front flanged heavy rod hydraulic cylinder into position using the appropriate mounting brackets or fixtures. Ensure proper alignment and stability during installation to prevent any misalignment or stress in the cylinders.

Hydraulic System Integration: Follow manufacturer’s instructions and guidelines to connect hydraulic lines to cylinder ports. The cylinder is integrated into the hydraulic system by connecting it to a suitable pump or power unit. Ensure cylinder specifications and operating requirements are met.

Control and Operation: The control valve in the hydraulic system is used to regulate the flow of hydraulic oil into and out of the cylinder. Adjust the control Settings according to the desired linear motion and force output. Test the movement of the cylinder to verify its function and responsiveness.

FB Rear Flange Type Heavy Rod Hydraulic Cylinder Maintenance:

To ensure optimal performance and longevity of the FB Rear Flange Type Heavy Rod Hydraulic Cylinder, regular maintenance is crucial. Here are some maintenance tips to follow:

Regular Inspection: Perform routine inspections to identify any signs of wear, damage or leaks. Check cylinder blocks, piston rods, seals and other components for abnormalities. Resolve any issues promptly to prevent further injury or operational inefficiencies.

Lubrication: Apply the recommended lubricant to the moving parts of the cylinder, including tie rods and seals. Regular lubrication minimizes friction, reduces wear and ensures smooth operation. Use the appropriate lubricant type according to the manufacturer’s lubrication interval guidelines.

Seal Replacement: If seals are found to be deteriorating or leaking, replace seals with genuine parts approved by the manufacturer. Damaged or worn seals can compromise the performance of the cylinder and can lead to leakage of hydraulic oil.

Cleaning: Remove dirt, debris and other contaminants and keep cylinders clean. Before reassembling, use a non-abrasive cleaner and make sure all parts are completely dry. Regular cleaning promotes optimal performance and prevents premature wear or damage.

How To Replace Seals In A Hydraulic Cylinder?

Replacing seals in a hydraulic cylinder requires careful attention and proper procedure to ensure successful replacement. Here’s a step-by-step guide on how to replace seals in a hydraulic cylinder:

  1. Safety Precautions: Before starting any maintenance work, take appropriate safety precautions. Ensure the hydraulic system is depressurized and the equipment is adequately supported and secured. Wear protective gloves and safety glasses to protect yourself from any potential hazards.
  2. Cylinder Removal: Depending on the specific hydraulic system and cylinder design, you may need to remove the hydraulic cylinder from its mounting location. Follow the manufacturer’s instructions or consult the equipment manual for the proper procedure to remove the cylinder.
  3. Cylinder Disassembly: Once the hydraulic cylinder is removed, carefully disassemble it to access the seals. Typically, hydraulic cylinders consist of a cylinder barrel, piston, piston rod, and various seals. Follow these steps:a. Remove the Cylinder Head: Unscrew or unbolt the cylinder head from the barrel, exposing the piston and piston rod.b. Remove the Piston: Gently slide the piston out of the cylinder barrel. Be cautious to avoid damaging the piston or the cylinder walls.c. Remove the Old Seals: Identify the seals that need to be replaced, such as piston seals, rod seals, or wiper seals. Use appropriate tools, such as seal removal picks or hooks, to remove the old seals from their grooves. Take note of the seal orientation for proper installation of the new seals.
  4. Seal Preparation: Inspect the new seals for any defects or damage before installing them. Ensure that you have the correct replacement seals that match the specifications of the original ones. Apply a thin film of hydraulic oil or seal lubricant to the new seals to facilitate proper installation and reduce friction.
  5. Seal Installation:a. Piston Seals: Start by installing the new piston seals. Carefully position the seals into their grooves, ensuring they sit flush and are not twisted. Use a seal installation tool or soft-faced mallet to press the seals into place gently. Ensure that the seals are evenly seated and properly aligned.b. Rod Seals and Wiper Seals: Move on to installing the rod and wiper seals. Again, position the seals correctly in their grooves, ensuring they are not twisted. Apply gentle pressure using a seal installation tool or a mallet to secure the seals.
  6. Reassembly: Once all the new seals are installed, reassemble the hydraulic cylinder. Follow these steps:a. Reinstall the Piston: Carefully slide the piston back into the cylinder barrel, ensuring it moves freely without any obstruction. Align any retention mechanisms, such as snap rings or circlips, as necessary.b. Reattach the Cylinder Head: Place the cylinder head back onto the cylinder barrel and secure it with screws or bolts. Ensure proper tightening according to the manufacturer’s specifications.
  7. Cylinder Installation: If you removed the hydraulic cylinder from its mounting location, reinstall it following the appropriate procedure. Ensure proper alignment and connection to the hydraulic system, including the lines and fittings.
  8. Testing and Inspection: Test its functionality once the hydraulic cylinder is reinstalled. Gradually pressurize the system and check for any leaks, abnormal noises, or improper operation. Conduct a thorough inspection to ensure the seals are performing as intended.
