Safety Measures to Take Before Beginning Installation
Shut down the hydraulics: Before you start, make sure the hydraulics are shut down. This eliminates the risk of accidental start-up, which could result in serious injury.
Clear the Work Area: Remove any obstructions from the work area. A clutter-free space is not only easier to work in, it is also safer.
Pro Tips for Increased Safety
Pressure Relief: Before starting any work, relieve the hydraulic pressure in the system. This is critical to prevent accidental leakage of hot, pressurized fluids.
Check for leaks: Use a piece of board or cardboard to check hoses for pinhole leaks. Do not use your hands, as hydraulic fluid can be injected into the skin and cause serious complications.
Correct Connections: Ensure that compatible high and low-pressure components are used. Mismatched components can cause ruptures and leaks.
Preparing the Hose
Before considering fittings and connections, start with the hoses themselves. Proper preparation is the cornerstone of a successful hydraulic installation. So how do you do it? Let’s take an in-depth look.
Properly measure and cut hydraulic hoses
Use a tape measure: The first step is to measure the hose. Grab a tape measure, determine the desired length, and mark it. Remember, it’s best to measure twice and then cut.
Use a hose cutter: After measuring, it’s time to cut. Use a specialized hydraulic hose cutter to make a clean cut. This will ensure a better seal and a stronger fit.
Tips to ensure a clean cut for an optimal fit
Clean the hose: Before you start cutting, wipe down the hose to make sure it is free of dirt and debris. An unclean hose can affect the integrity of the joint.
Double-check measurements: It may sound obvious, but always double-check measurements before cutting. A small mistake here could lead to a bigger problem.
Hose preparation considerations
Consider hose expansion: Hydraulic hoses can expand or contract due to pressure and temperature. Be sure to take these changes into account when taking measurements.
Check manufacturer’s requirements: Different manufacturers have different measurement standards. Always check with the manufacturer to avoid wasting scrap.
Assembling reusable fittings onto hydraulic hoses is a task that requires precision and attention to detail. While the steps may seem simple, each one plays a vital role in ensuring a safe and efficient hydraulic system. Let’s take a closer look at the importance of each step and some best practices.
Insertion of fittings
Slip fitting: Secure the reusable fitting and insert it into the hose. If there is resistance to insertion, use a little pre-prepared lubricant.
Check the fit: Make sure the fitting slides in smoothly while maintaining a tight fit. Looseness can lead to leaks, while tightness can make it difficult to secure properly.
Tighten by hand
Start by hand: Initially tighten the fitting by hand. You want to align the threads and make sure they do not deflect. (The threads are left-handed, so remember to rotate them to the left.)
Feel the resistance: When tightening by hand, you will feel some resistance. This is a good indication that the threads are engaging properly.
Double-check: Before moving on to the next step, double-check to make sure the fitting is securely hand-tightened.
Grab your wrench: Select an adjustable wrench that fits the size of the fitting.
Turn carefully: Start turning the wrench slowly, making sure not to over-tighten. Over-tightening can cause the hose to distort or even strip the threads, compromising the integrity of the connection.
Final Check: After tightening the fitting, do a quick check to make sure it’s secure. Look for any signs of misalignment or gaps that could indicate a problem.
How to tighten the fitting correctly
Use an adjustable wrench: Take the adjustable wrench and place it on the reusable fitting. Turn the wrench until the fitting feels tight. At this point it is tight enough to form a seal, but not so tight as to damage the hose or fitting.
Common mistakes to avoid
Overtightening: This is the most common mistake and can lead to a host of problems, including leaks and even cracked joints. Always follow the manufacturer’s torque specifications, if available.
Misalignment: Make sure hoses and fittings are perfectly aligned before tightening. Misalignment can lead to improper sealing and potential leaks.
Pro Tips for Safe Installation
Marking Technique: Use a marker to draw a line on the nut and extend it across the adapter. This helps you measure how tight the fitting is.
Check and recheck: After fixing, it’s a good idea to double-check. Make sure there are no gaps or misalignments.
After assembling the hydraulic coupler, you are not done yet. The next critical step is to test the installation. This will ensure that the fitting is secure, leak-free, and ready to go.
Leak and Flow Test Procedure
Turn on the hydraulic system: The first step is to start the hydraulic system. This allows you to monitor pressure levels and ensure that the system is operating properly.
Check for leaks: Once the system is turned on, carefully inspect the fittings and surrounding area. If leaks are found, they will need to be rechecked or reinstalled.
Solutions to Problems
Retighten fittings: If the problem is not serious, then you can fix minor leaks with a simple adjustment.
Replace the hose: If the leak persists, then you’ll need to find out where the leak is occurring in your hydraulic system, and then you’ll need to replace the hose or fitting with a new one.
Use a calibrated gauge: Always use a gauge that has been calibrated within the last 12 months. This ensures accurate readings.
Follow an approved test program: Always perform tests under controlled conditions and record the results. This not only ensures safety but also helps with future troubleshooting.
Hydrostatic vs. barometric testing: Hydrostatic testing uses water as the test medium, while barometric testing uses air or a non-flammable gas. The choice between the two depends on your specific needs and system design.
Maintenance and Troubleshooting
With hydraulic systems, proper maintenance ensures that reusable hydraulic hose fittings last longer and perform better. Let’s take an in-depth look at some maintenance tips that can save you time and money in the long run.
