BE FAMILIARIZED WITH THE HYDRAULIC VALVES USED

First, you need to be familiarized with the type of hydraulic valve in the system as they consist of different parts and you need to know how to disassemble, and assemble them. Once you have disassembled the hydraulic valve you need to check for the different parts if they are worn-out for instance the o-rings. Moreover, you need to remember to always maintain cleanliness while working with valves and keep them free of dirt.

Remove the old o-rings, burrs, and nicks of the different parts found within the valve to make sure they are smooth and not penetrated by the fluids. You may find that some parts work together with others. If any burrs are present, this may cause contamination or friction on the different parts. All sliding and moving parts need to be smooth.

Clean all disassembled parts, dry them properly, and replace the o-rings before assembling. Inspect the plunger seats and the body of the valve for wear and tear. Do thorough inspections not missing worn-out parts.

Make sure to inspect the hydraulic valve springs and tapered portion of the pin making sure they are not used up making sure they last to the next maintenance schedule. Provide lubrication to the different parts to prevent friction and have them functioning properly. Assemble all parts of the hydraulic valve with care or if you are not sure on how to do this rather call in one of A-Tech’s Hydraulic technicians to come and assist you.

Keep maintaining your hydraulic system to keep it working for a long time. If you are not sure on how to take care of your hydraulic system – A-Tech Hydraulics Services is standing by to help you with all your hydraulic needs.

Hydraulic Solutions for Fluid Monitoring in Hydraulic Test Stands

One major aspect overlooked in routinely servo/hydraulic-based test systems is the fluid status. Many of A-Tech Hydraulics customers knows how to monitor flow, temperature, and pressure, but do not consider testing the fluid itself, possibly one of the most important feature associated with the test data.

Many customers normally have effort with stand-to-stand confirmation, which in many occasions is the cause of test fluid and not the process or test components itself.  Water concentrations, fluid contamination, viscosity, and temperature all affect in general testing results and system response.

By controlling these variables with some easy to follow hydraulic solutions, you can get reliable test results while getting longer life from your testing equipment.

Fluid contagion

One of the main culprits connected with poor stand-to-stand validation and system response issues is fluid contamination. Inadequate monitoring and the use of dirty oil, or presuming that the fluids being uncontaminated by the hydraulic systems, filtration may be source of all your problems.

Is clean actually dirt free? Many maintenance teams do not grasp that “new oil” is in fact “new dirty oil.” Most new oils, unless ordered to a particular contagious level, is filtered to approximately 35-micron level. Without proper cleaning, adding new oil is simply contaminating your existing oil.

The only hydraulic solution to this problem is to document your fluid conditions and monitor the contagion levels. This you can do through on-bench in-line or offline testing. With a reasonably priced in-line monitoring structure you are informed of the present fluid conditions, fluid trending conditions, and able to label each tested part with the existing fluid test contagion levels through the data acquisition system.

By monitoring contagion, you are able to catch potential fluid problems and notify your technicians or us before it influences the result of your test.
