A demonstration of how simple it is to perfectly clean tubes
intended for hydraulic use, where the tolerated internal
contamination level is extremely low.
In the second part of the video it is shown how, more
generally, it is also possible to internally degrease the tube
by combining the mechanical action of the projectile with the
chemistry by soaking the projectile in a suitable liquid.
If needed, instead of degreasing, it is possible to wet the
projectile with hydraulic oil to lubricate the inside of the
pipe.
A video-guide that shows the ideal procedure to check and
clean hydraulics hoses.
The first thing to do is to check the quality of the coil, a
shot in the tens or even hundreds of meters of a new roll
requires a few seconds and allows to verify whether the inner
rubber wall of the hose is well vulcanized or if it tends to
lose particles continuously. Done this, the danger of contamination comes from the cutting
stage, where particles of different sizes are generated, which
is important to remove before moving on to crimping. The hoses can be cleaned even if they have been already
crimped, but when there is the possibility, we recommend to
perform this operation before mounting the fittings.
The PYPLOK weldless fitting solution (distributed in Italy by
Hexafluid s.r.l.), shown in this video, shows how the
combination with the ALKA Pro-Clean system is ideal to obtain
the best possible cleaning results from processing residues.
The fact that no wastes are created with the welding operation
allows the projectiles to carry out the removal of the
residues of the cutting and dust with great efficiency,
obtaining in a short time a pipeline suitable for use in the
most demanding fields.
The
hydraulic revamping operation at Eredi Gnutti S.p.A.,
carried out by System Fluid s.r.l., provided for the
complete replacement of the hydraulic piping of a Mino
LQ65 mill for copper, brass and bronze. Gusmeri
Automazione, authorized distributor Bosch Rexroth,
provided a new low pressure power unit and new valve
banks, as well as being involved in the revamping of the
high pressure power unit.
The
new lines are made with a WalformPlus system to avoid
excessive waste production resulting from the welding
process and to minimize the presence of machining residues
inside the circuit. The
traditional oil flushing has been replaced entirely by a
mechanical cleaning carried out using the ALKA Pro-Clean
system, with which all the residual particles and
contaminations were removed in a few hours, while
connecting the pipes, thus guaranteeing an immediate start-up
without any issue.
An example of cleaning a series of 130mm flanged pipes
for hydraulic use.
The interconnection of the individual segments does not affect
the ability of the projectile to travel the entire line.
The operation allows the removal of metal chips, various
processing residues and extremely dangerous welding residues.
A demonstration of how you can clean and degrease the pipes
for hydraulic cylinders. A simple, effective and faster way
than the manual cleaning with the ramrod.
With the ramrod the cylinder takes several minutes and the
level of cleanliness depends on the skills of the operator, but
you can never reach the level of cleanliness achieved manually
with our projectiles that always guarantee an optimal outcome.
To clean a cylinder you need only a few seconds, with the
great advantage of significant cost savings in manpower. It's important to wet the projectile with the suitable liquid
degreaser! In this case, you see a pipe having an internal diameter of 80
mm, but also larger diameters, i.e. 150 mm, can be cleaned.
A demonstration of how you can clean the hydraulic pipes
supplying a power hydraulic unit belonging to a new plant. In
this case, there were approx. 20 shaped, welded and connected
tubes of different diameters, with an approx. length of 30
meters each.
A simple, efficient, fast and very low cost cleaning
alternative compared to oil flushing which would require many
hours of work.
With our system you can eliminated hazardous waste particles
that remain attached to the inner wall of the piping, but
could detach after days or months of oil flushing during
ordinary work.
