Now you should clean new hydraulic rubber hoses!

Now you should clean new hydraulic rubber hoses!

Seeing this title, I think you already have a big question mark in your heart? Is the new hydraulic rubber hose not a clean hydraulic rubber hose? Then I will tell you now, of course not! Even hose that looks clean can have plenty of dirt and contaminants inside. Next,let us reveal the puzzle.

Comparatively little has been said about the importance of cleaning hydraulic lines. The idea that “new” equals “clean” is a big misconception. In fact, very few hose manufacturing facilities incorporate any type of cleaning methods in their fabrication processes.

On the contrary , a great deal of time and attention has been placed on the importance of keeping hydraulic oil clean. As a result, a vast number of studies and articles have been written on oil filtration. Anyone worth his or her now knows that oil needs to be clean to obtain optimum equipment performance. But do you know what happens to clean oil after it passes through dirty hydraulic rubber hose? It's dirty now!

After factory produce hydraulic rubber hose, need to clean the hose. If you are a large company that has a lot of hydraulic machinery and a lot of highly trained hydraulic individuals, you know how important it is to have clean hydraulic oil. One of the sources of hydraulic contamination is from ingression. Ingression happens anywhere where it’s added to the system through just plain dirt dropping in your reservoir, from steel filings or from anywhere outside the system. You don’t want to be additive to that if you’re doing hydraulic hose assembly.

For example:

1.Cutting a hose into smaller lengths for hose assembly generates rubber dust in the tube.

2.Crimping causes “flashing” of small metal shards to break off into the line.

3.Leaving a finished hose unsealed allows air-born dust and grime to enter the line. (Or, worse, the hose gets thrown into the back of a dirty truck during transportation to the job site.)

4.By the time the finished product is installed onto the equipment, the amount of contamination build-up has been sufficient to ruin even the cleanest oil. Hydraulic tubing can be just as bad: bending, flaring, and deburring all leave both visible and microscopic particles inside the line that can effectively destroy precision parts on equipment.

You need to clean the hose, so that the particles from cutting and skiving and crimping—the entire assembly process—doesn’t add to the contamination of the system, especially if you’re trying to adhere to a particular ISO code of cleanliness. You need to use only approved cleaning apparatus, and there are a couple of companies out there that do it. After you clean the hose, you must immediately cap the hose to protect from environmental contamination. They may go in a shipping area, or they maybe go to an area on a machine integrator where they build the machine where there’s grinding and welding, you want these hoses laying around with the ends open or everything just falls right into it, so then you’ll cap it.

Some cleaning apparatuses use foam pellets that are fired through the hose, picking up all the contamination. The idea is to fire this in both directions. Typically, you fire it after the hydraulic hose assembly is manufactured. Shoot it out the other end, and then cap it. This protects it from any ingress contamination, and then you have yourself a complete hose.

Today I wouldn’t buy a new hydraulic line without getting it cleaned . Cleaning or flushing hydraulic lines is critical to keeping your machines contamination-free. And cleaning your hose can be as simple as using pneumatics to shoot a special projectile through the hose to collect debris and contaminants. Your systems are too important not to do this.
