Introduction
Do you have single-acting hydraulic cylinders? What happens if the air traps into the cylinder? The result is straightforward— entrapment of air causes the failure of the cylinder.
Sometimes, it fails to provide sufficient power.
At times, it fails to provide any power. Therefore, bleeding the single-acting hydraulic cylinder is an essential maintenance task that promises seamless power generation. But how do you bleed the hydraulic cylinder?
If it is your question, this guide is for you. We have added detailed tools, materials, and tips to ensure the safe bleeding of the hydraulic cylinders.
What is a single-acting hydraulic cylinder?
A single-acting hydraulic cylinder is one of the most common options for operating in one direction. It extends under the hydraulic pressure and has a spring or gravity to retract through the external force.
Such hydraulic cylinders are ideal for various activities, such as lifting or pushing.
Here are the crucial characteristics of single-acting hydraulic cylinders.
- One fluid port. Since it is single-acting, only one port allows the fluid flow and helps create the power.
- Return mechanism. External forces or gravity can retract the piston.
- Air entrapment risks are higher in such hydraulic cylinders because of how they act.
Why do you need to bleed the single-acting hydraulic cylinders?
Trapped air is a risky deal that comes with the reduced performance of the hydraulic cylinders. Here are a few more reasons to understand why you should bleed the hydraulic cylinders.
Elevated heating
Since the air is trapped, there is more chance for heating. The overheating can cause the functional impairment of the system. It also damages the different components of the single-acting hydraulic cylinders.
Reduced Performance
A single-acting hydraulic cylinder depends more on fluid flow. What if your flow gets down? Air entrapment causes the air pockets. It leads to the diminished movement of the cylinder and decreased performance.
Inconsistent operations
The air causes the unequal distribution of the force. There is no effective retraction and extension of the hydraulic cylinders. It leads to inconsistent performance.
Component wear outs
You might not believe it, but the seals can break easily when the air is trapped in the system. This leads to the wear out of various components and the short lifespan of hydraulic cylinders.
Materials and Tools needed for the bleeding
You need various tools and materials to bleed the hydraulic cylinders. These include:
- Wrench set to set the bleed screws and optimize them.
- Fluido idraulico should match the specifications of the hydraulic cylinder.
- Bleed valves to maintain the airflow and bleed the cylinder.
- The catch pan catches the air bubbles and helps remove the fluid.
- Clean rags can eliminate the fluid and maintain cleanliness.
- Protective gear can offer endless safety to consumers.
Step by Step Instructions to bleed single hydraulic cylinders
Do you want to bleed the hydraulic cylinder and don’t know how? Relax! We have added step-by-step instructions with tips and tricks.
Let’s shower light on all aspects.
Step 1: Evaluate and Position the Cylinder
Before you start your job, it is time to evaluate the cylinder. You can check:
- If there is any leak in the connection or hoses.
- The cylinder has proper fittings.
- Fluid levels are normal in the hydraulic cylinder.
Now is the position of the hydraulic cylinder. You can select a stable area to place your hydraulic cylinder. Turn off the machine if connected and stabilize the position of the hydraulic cylinder.
Step 2: Check the fluid reservoir
Remember, the bleeding can consume some fluids. Having appropriate fluid levels is a good idea. However, if you think there is more space for the hydraulic fluid, feel free to add it.
Step 3: Open Bleed Screw
A bleed screw or valve can help eliminate all the air and bubbles through it. Do you have the bleed screw available on your hydraulic cylinder?
There must be a hose fitting. Try that one for the opening of the hydraulic cylinders. It leads to better clearing of the air.
When opening the bleed screw, you must place the catch pan. It will help catch the bubbles and clean up the air.
Step 4: Operate Cylinder
Most times, opening the screw valves doesn’t remove all the air. So, is there any solution to remove it? Yes, you can manually operate the hydraulic cylinders.
Extend and retract the cylinder and observe the air and fluid bubbles removal. You can trace the air removal or fluid by the bubbles. If bubbles are escaping, it means your efforts are successful.
Do this until all the air is eliminated from the hydraulic cylinders.
Step 5: Tighten Bleed Screw
Have the air bubbles blown out of the hydraulic fluid? Only the clear comes without the air bubbles. It shows there have been no more bubbles.
Tighten up the screws efficiently and enjoy the next-level performance. Remember to avoid the overtightening.
Step 6: Test
Have you followed all the steps and successfully removed the air? It is time to test the hydraulic cylinder.
You can look for the following signs.
- There are no interruptions to the hydraulic cylinder functionality.
- No noisy and irregular sound is coming out of the hydraulic cylinder.
- Observe any irregular behavior due to trapped air.
Now, there are two options.
- If the operations of the hydraulic cylinders are consistent and efficient, move ahead. You can fix it for further usage.
- If the operations of hydraulic cylinders are interrupted and facing some air entrapment until now, go to the rebleed. Repeat the process until there is no air trapped in the hydraulic cylinder.
