5-5. Manifold Piping
Manifold piping should be worked with being careful on
the following matter.
(1) Manifold piping (1/2) is required that piping of
transverse direction is performed after starting
stand-up piping (1-2m) from lubrication unit. Piping
of transverse direction should give a slope of 2/100
～5/100.
・Before starting piping work, confirm the position of
branch-out, Fog-Nozzles and etc.
・When connecting piping to the lubrication unit, take
care not to jam the seal materials and dust into
the piping.
(2) Before starting piping work, piping should be
washed in pipe cleaning water and blow air to
remove dirt and scale. Flushing by compressed air
after piping work is also necessary.
(3) Piping should have the smooth inside and should
lessen use of pipe bends or pipe fittings as much as possible.
(If the flow of air becomes turbulent flow in piping, oil quantity condensed inside piping will
increase).
(4) The main manifold piping from the Micron-Lub lubrication unit to the machine to be lubricated is
preferably made of non-corrosive 1/2 pipe for gases. A
slope of 2/100～5/100 on the main manifold should be
provided descending toward the lubrication unit, and
avoid having a down loop in the course of the manifold
piping.
(5) Branch piping that distributes fog to each lubricating
point should be obtained from upper side of the main
manifold piping. Joints for branch piping should not
project inside of the main manifold piping.
(6) Install oil drainage equipment at the lowest place of
down looped piping and at bottom of standing-up
piping. Accumulated drain would be easily expelled.
(7) Check points for Fog-Nozzles.
・Type and lubricating capacity (Nozzle size).
・Installed position and the number of Fog-Nozzles.
・A distance from the tip of Fog-Nozzle to the parts to be lubricated.
・Provision of a vent port with sufficient vent, and protective method to oil contamination of
surroundings.
