5. Thread the face plate, with the nozzle containing the projectile, onto the base of the gun. Make sure the threads are fully engaged and tighten the face plate hand-tight, to seal the face plate to the base of the gun.
Thread Face-Plate Into Locked Position
Containing the projectile that comes out of the hose is important to prevent personal injury. Projectiles and contamination, expelled during the cleaning process, can cause personal injury.
6. Make sure the exit end of the hose is inside a container that will prevent it from being forcefully ejected, causing possible injury.
Use A Container To Catch Projectile It is important to recover the used projectile, so it can be analyzed to determine the condition and cleanliness of the hose.7. Place the nozzle firmly against the end of the hose or fitting, making a tight seal. It is important to obtain an air tight seal.
Place Nozzle Firmly Against End Of Hose Or Fitting8. Depress the trigger, making sure it remains depressed until the projectile emerges from the other end of the hose. If the trigger is released prior to the projectile emerging, it will remain in the hose until the trigger is depressed again.9. A projectile should be fired from both ends of the hose or tube. Repeat until the necessary cleanliness is achieved. After connectors are attached, a projectile should then be fired through the assembly to make sure that any possible contamination introduced during assembly (lubricants, rubber, etc.) is removed. Repeat until the necessary cleanliness is achieved. Research has defined four standard hose cleaning procedures for the hydraulics industry. To obtain the desired cleanliness levels, the following procedures are recommended.Projectiles
Path
To clean a system successfully, be careful to identify all intersections, changes in bore size, and obstructions due to control valves, pumps, and monitoring equipment.Hose length does not matter (with a suitable air supply volume), a projectile can travel up to 1,000 m (3,000 ft). The number of bends or coils in the hydraulic system is not a factor in the distance the projectile will travel. Even lines crossing at right angles are not a problem. However, the hose must have both ends open to the atmosphere at the same time.It is, however necessary to consider the projectile's path in a complex system. It may travel through partially restricted hoses, connectors, and open ball valves. In some installations, it will be necessary to isolate the system into separate sections. Also, any branch hose coming from the main line must be capped.The illustration below provides a few examples of path selection.
Select Best Path For Projectile. If more than one path is available, cap one of the paths.Storage and Disposal
New projectiles should be stored in boxes so they are not exposed to direct sunlight or fluorescent light since they can cause discoloration.Used projectiles must be disposed of properly.Hose Cleaning Projectiles
