Introduction
Welded hydraulic cylinders play a remarkable role in the generation of energy. They transform the fluid force into linear work and help optimize work efficiency.
Whether pressing or pushing, heavy-duty tasks can degrade the functionality of the hydraulic cylinders. They need the repair and timely assessment.
That is where you have to come up with the rebuilding ideas. How can you rebuild a welded hydraulic cylinder? If not, this guide is for you. We will discuss rebuilding a welded hydraulic cylinder and enjoying a flawless performance.
Why should you rebuild a welded hydraulic cylinder?
Rebuilding can be a good idea because it comes with tons of benefits. All those benefits are related more to savings and offer hassle-free functionality.
Let’s see why you should think of rebuilding!!
Cost efficiency
Do you want to buy a new hydraulic cylinder? Buying a new one can be more expensive than repairing the current one. So, it saves costs and decreases the overall budget.
Reduced downtime
Purchasing the new tools comes with the hassles of visiting the place and waiting for the installation. On the other hand, repairs occur on the site and provide better access.
Sustainability
Recycling and reuse of different components is always an eco-friendly idea. It is because of the positive impact on the environment.
Signs that show the rebuilding of welded hydraulic cylinders
It is not always repairing you who should go with the rebuilding. There are a few signs you should look for before thinking of rebuilding.
Leaking hydraulic fluid
Closely assess the various components of the hydraulic cylinders. See the fittings. Can you observe any leakage of the hydraulic fluid? If yes, it is time to go for the rebuilding.
Decreased performance
Decreased performance is a clear-cut sign of the hydraulic cylinder wearing. It can also prompt the hydraulic cylinder rebuild and repair for efficient functionality.
Abnormal sounds
Can you hear the excessive sounds? Excessive knocking and grinding are other signs that you must go for the repair of your hydraulic cylinders.
Physical damage
Bent rods and barrels are physical signs to observe. If you find any signs, get ready to do real-time tasks here.
Tools and materials needed for rebuilding
Before you start rebuilding, it is better to prepare your tools.
So, what tools do you need? Here is the comprehensive list.
- Chaves de boca. These help tighten up the fittings. Sometimes, you can help remove bolts and fittings.
- Hydraulic Seal Kit. This kit has all the replacement seals and O-rings. Ensure they match the specifications of the hydraulic cylinder.
- Cylinder Repair Bench. A secure place to work on the cylinder.
- Alicate para anéis de pressão. They help remove retaining rings.
- Pry Bars and Screwdrivers are premium tools for the disassembly of different components.
- Torquímetro. For precise reassembly, torque wrenches stand out as premium tools.
- Suprimentos de limpeza. Rags, solvents, and brushes are ideal for cleaning your hydraulic cylinders.
- Ferramentas de medição. Calipers or micrometers give accurate readings for your measurements.
- Grinder or Cutting Torch. They are impactful for the elimination of welded end caps.
- Fluido hidráulico is the magic fluid that delivers vital power. Refill the system with hydraulic fluid after rebuilding.
Step-by-step Instructions to rebuild a welded hydraulic cylinder
Rebuilding a welded hydraulic cylinder is not challenging if you know the step-by-step guide. Let’s explore the various steps here.
Step 1: Prepare workspace
Have all your tools ready. Prepare your safety kit with goggles, gloves, and other components.
Choose a stable surface for work. Check if you have all the replacement components.
Step 2: Drain hydraulic fluid
Disassembly can cause the spillage of the hydraulic fluids. Therefore, drain it. Open and disassemble all the hoses and fittings to drain all the hydraulic fluid from different components.
Step 3: Disassemble Parts
Real work starts now! Disassembly of the different components tests your skills. You can consider:
Cut the welds
Cut the weldings. Use the cutting torch while saving the end caps. Reduce the damage by thoroughly cutting the components.
Remove rod
Remove the rod and piston out of the barrel. Avoid any damage during the sliding activities.
Disassemble rod
Now, you can remove all the components thoroughly. Piston, rod, and seals. Remove all the parts. Use snap ring pliers for this job.
Scrutinize components
Now, look at all the components. Can you see the signs of wear and tear? If yes, it is time for repair and a timely approach.
Step 4: Clean Hydraulic System
You should assess all the hydraulic cylinder components. Scratches, dents, and cracks are prominent in the hydraulic cylinders. Also, check the piston for wear and tear.
Step 5: Replace Seals and O-rings
Seals and O-rings are often the culprit for most of your wearing tasks. For example, their wearing and improper functionality can leak the fluids and damage other components. Behind the decreased performance of hydraulic cylinders are also crucial components.
So, replacing the old and worn-out seals with the newer ones is better. Use the seal kit and install the newer seals and rings. Recheck for the leakage of fluid. Verify the fundamental working mechanisms.
Step 6: Reassemble
Once you have removed and cleaned parts, it is time for reassembly. You can reassemble by:
- Install rod assembly. Prepare the piston and gland to attach it to the rod.
- Insert the rod into the barrel. Slide the rod into the barrel.
- Secure end caps. Weld the end caps and secure all the components.
Step 7: Test System
Congrats! You have done a great job! It is time for the final hit— test the system. Inspect components and check the functionality.
