Hazards of Hydraulic Hoses and Hose Leaks
Maybe you won't believe it, the hydraulic hose assembly and connections are not designed to leak or leak, but they still miss it. If there are leaks in them, then there is a mistake. Leaks in high-pressure hydraulic lines are not only an arbitrary mess, they are also dangerous. Leaks can pose a slip, fall and fire hazard and pollute the environment. Leaks can cause skin burns in the body, as well as liquids can penetrate the skin with high pressure.
The most common causes of leaks in hoses are abrasions, abrasions, and improper assembly. If you are working with hydraulic hoses, you need to be able to know the problems that may occur in advance, to prevent them and to have the skills to fix them.
Preventing Problems:
It is imperative that the hoses are of the correct length and diameter in order to prevent abrasions. Make sure that the hoses are used with the hanger, support and latch materials intended to be used by the machine manufacturers. If the initially existing wear protectors are missing, they must be replaced. Do not ignore any damage to the outer layer. Such damage can cause the braid system, which provides the pressure resistance of the hose, to rust by being moistened with water; Rusting, on the other hand, can cause the hose to become inoperable.
Mistakes in the Detection and Elimination of Leaks:
What happens if a leak is detected in the connections? Do you find a wrench and tighten the connection one more tooth? This overtightening can lead to a larger leak or even the connection becoming inoperable.
Do not use your hand to locate the leak. Instead, you can make use of a piece of cardboard or wood. Hydraulic fluid is hot and can burn your skin. Due to the leakage as large as a pinhole, the liquid can be injected under your skin with pressure, causing poisoning and infection, posing a great danger to your life and limbs. There have been such cases.
Leak Test:
Before the test is performed, turn off the machine and reduce the hydraulic pressure of the system. If the hose slips off the fittings or the connections break under pressure, severe injuries and fires can occur due to the sudden release of hot hydraulic oil. Leaks usually occur due to improper installation and damage to the system.
Pay particular attention to the following:
- Both ends are clean from the inside and outside, and there is no physical damage,
- The use of new gaskets, clean and lubricated without connection,
- so that the seals and sleeves are not destroyed, metal fatigue, excessively tightened, so as not to cause cracks,
- Connections to luminaires are generally compatible with each other. However, there are so many different connectors that they can sometimes be almost compatible, but not quite.
It is very important that the hose ends are properly assembled. If the pressurized hoses break free from the connections, they bounce back like a whip with great force, causing a large amount of hot hydraulic oil to disperse into the environment. The reasons for leakage in the fixture connections; We can count it as not tightening the groove teeth sufficiently, not cutting the hose thoroughly and cleanly, and not fitting the root connections into the hose sufficiently.
If you are installing the hoses yourself, make sure that the clamping mounting cheeks used are not worn. If the sidewalls of some clamping machines are worn, the tightened section may remain loose.
Screw type clamps should not be used in pressurized hydraulic systems. People who work with any type of fluid communication piping system know that clean, painstaking workmanship is required to prevent dangerous leaks.
If you see a leak, report it immediately. If your job is to repair such leaks, do so carefully and safely.
