•
Check frequently all structural parts and rotating parts (shaft, bearing, leading
screw, worm gear reducer, planetary reducer and cycloid pinwheel reducer). Resolve
the problem in time if there’s any.
k) Overhaul of Antenna Pedestal ( the equipment should be stopped, once every three years)
•
Check if all parts and components are damaged. Replace the damaged one in time if
there’s any.
•
Clean, derust and oil all moving parts to guarantee flexible movement.
•
Clean and adjust the axis, bearing, leading screw, worm gear reducer, planetary
reducer and cycloid pinwheel reducer. Replace the damaged or nearly damaged
component in time and apply enough lubricant (the lubricant grease is MnS2 EP lithium
grease, the oil is high-grade heavy-duty gear oil) at the same time to ensure flexible
movement. The lubricant grease and oil should be filled as described in (q). The grease
and oil must be filled sufficiently, missing and inadequacy will cause serious results and
the moving parts will be damaged in short time.
•
Painting: spray paint in an all-round way once every three years. Clean the original
lacquer coat before painting, then paint it with zinc chromate primer as required
(once to twice) and white polyurethane enamel (twice to three times as required).
l) There’re two levels of moving speed of the antenna: fast and slow. The fast level is used
for antenna section changing, stowing and satellite searching and the slow level for
tracking satellite in normal operation.
m) In case of natural disasters such as windstorm and earthquake, check the equipment
constantly and replace the damaged parts and components in time.
n) When the wind speed has reached the speed to stow the antenna, if extremely strong wind
above Grade 10 is forecast (consider the wind speed at that time according to the
forecast), rotate the antenna 2 hours in advance to the stowing position facing the sky.
o) The leading screw cover is used to protect the leading screw. If damaged, repair or
replace it immediately.
p) Check the shaft, bearing, leading screw, worm gear reducer, planetary reducer and cycloid
pinwheel reducer once every three months and apply lubricant (the grease is MnS2 EP
lithium grease, the oil is high-grade heavy-duty gear oil) at the same time to ensure
flexible movement. The method is:
•
Apply lubricant grease to the AZ and EL reducer box. Take down the organic
glass plate from the box, then fill up with mushy lubricant mixed by MnS2 EP lithium
