Hydraulic Seals For Improving The Performance Of Hydraulic Cylinders

Hydraulic Seals For Improving The Performance Of Hydraulic Cylinders

Hydraulic cylinders are commonly known for their reliability subject to some conditions. However, the extended functionality of the cylinders is based on how it was manufactured. According to researchers, the hydraulic cylinder is made using excellent manufacturing processes that function well for an extended period without any downtime. However, this will only happen if the hydraulic cylinders are subjected to regular checks and maintenance. You, however, need to be aware that the hydraulic system is complicated, and it needs support more often.

The hydraulic seal is the most significant component of hydraulic cylinders. Therefore, the function of the

Hydraulic and pneumatic seals

is, preventing leakage from the cylinder. Doing this rules the seals out effectively, and there is no need for replacing the damaged cylinder. Besides, the seals keep unique materials like dirt, metallic chips, moisture, and weld flash from getting into ten hydraulic systems.

Checking For Bent Rod And Correcting

Bent rods are not common in the case of hydraulic cylinder systems because they are only formed from a design flaw. The causes of the bent rod may include insufficient rod diameter of irregular mounting arrangement. It may also occur because of poor quality material used during the manufacture of the hydraulic cylinder system. Thus, if the bent rod is not detected earlier enough, it may lead to damage to the entire system in the long run. It is necessary to check the rod of the hydraulic cylinder more often to improve the performance of Hydraulic cylinder piston seals.

The Ballooning Of Cylinder Tube

The pressure of the hydraulic cylinder has a more significant impact on cylinder tube ballooning. The ballooned tube leads the way for braking of the seal and leakage of the fluid. Therefore if the problem is not solved, it will lead to the dropping of the efficiency of the hydraulic cylinder. This is why the hydraulic cylinder tubes should be checked regularly to ensure the maximum efficiency of the operation.

Checking The Bearing Area

This is also another efficiency maintenance step that should be taken to promote the long life of the seal. When there is an insufficient bearing area, there will be a considerable load on Hydraulic cylinder piston seals. The load is likely to be high than what the seal can withstand. Therefore, in the long run, the seal will fail, and this leads to a complete replacement of the whole sealing system. To avoid this and ensure the sealing performance is up to standards, you should check for any abnormalities and correcting them as soon as possible.

Checking The Surface Finish Of The Rod

There is a specific roughness requirement for the rod. When the surface is rough, there are chances that the fluid will leak. Therefore for a smooth surface, it is essential to lower the life of the seal. This means checking the surface regularly and ensuring it is up to standard. Maintaining and periodically check of these parts will promote long growth and maximum efficiency of the hydraulic cylinders.

In case the hydraulic cylinder fails, here are some steps that you to take in repairing it using hydraulic seals.

 Step 1 Dis-assembly

You need to take the cylinder off from the machines, open the cover of the cylinder, and remove the piston from the cylinder. Then loosen the inner valves to reduce the pressure and slide the piston shaft out from the cylinder.

Step 2 Inspections: 

This is an essential step in hydraulic cylinder repair. You are required to do a visual inspection to determine the problem if the cylinder bore is scratched off the piston shafts is bent. Then you need to find a professional hydraulic cylinder repair. You can find one by visiting

to direct you to the experts. When the seals are ruptured, they lead to an excessive leak of hydraulic fluid.

Step 3 Re-pack The Seals: 

Using DZ Ding Zing Hydraulic Seals and the repacking instructions dislodge the old seal from its position and fix the new one in the same place. In this stage of repair, you are required to lubricate the seals with oil and gently slide the piston back to its position.

Overall, it is vital to ensure the valves are loosed for easy placing of the piston. Before you attach the cylinder, you should check for leakage as well as the condition of the hydraulic hoses.
