Hydraulic Valve Block 35-220L Flow Aluminum Cast Ductile Iron Steel Hydraulic Valve Aluminum Processing Service

Manifold blockage is a common problem in hydraulic systems and requires careful handling. Here are some steps to deal with it:

Identify the problem:

Observe whether the system pressure drops, the flow rate decreases, or the system does not work properly.

Determine whether a single manifold is blocked or the entire system is blocked.

Shutdown inspection:

Stop the system operation when it is safe.

Disconnect the power and pressure source to ensure that no pressure remains in the manifold.

Disassembly inspection:

Remove the blocked manifold or related components.

Inspect the inside of the manifold for foreign matter, sediment or damage.

Clear the blockage:

Use compressed air, a soft brush, a special cleaning tool or a solvent to clean the blockage.

If the blockage is hard or difficult to remove, mechanical methods such as a drill or grinding head may be required.

Check the filter system:

Check whether the filter in the system is blocked or damaged, and replace it if necessary.

Ensure that the cleanliness of the oil meets the system requirements.

Check the oil:

Check whether the hydraulic oil is contaminated or deteriorated, and replace it with new oil if necessary.

Ensure that the type and grade of the oil meet the system requirements.

Check components:

Check whether the valves, sensors and other components connected to the manifold are working properly and whether there is any damage.

Flush the system:

Before reassembling the manifold, it may be necessary to flush the system to remove residual contaminants.

Reassemble:

Clean and check all seals and connections to ensure that they are intact.

Reassemble the manifold and system to ensure that all connections are correct and tightened.

Test run:

After the system is reassembled, perform a test run to check if there is still blockage.

Monitor system pressure and flow to ensure that it returns to normal.

Record and prevention:

Record the cause and treatment process of the blockage for future prevention and rapid response.

Consider taking measures to prevent future blockages, such as improving the filtration system, regularly changing the oil, and strengthening daily maintenance.

When dealing with manifold blockage problems, be sure to follow safe operating procedures, use appropriate personal protective equipment, and seek professional help when necessary. Improper handling methods may cause system damage or safety accidents.
