as follows:
Use spindle prints to determine lowest point where
a.
oil may collect.
Drill a 0.562 inch (14.29 mm) hole in relief valve
b.
location.
Tap hole to 3/8-18 NPT.
c.
Install relief valve in tapped hole.
d.
2.2.4.2
Approximately 1 gallon (3.785 liters) of oil will drain from
the relief valve for every 200 hours of spindle operation.
A drain line should be connected to the outlet of the
relief valve to direct the drainage to a safe collection
point.
2.2.5
Divider Valve Installation
2.2.5.1
Divider valves are used on both SG-1 and SG-2 sys tems
to provide the required amount of lubricant to bearings
or nozzles. Divider valves should be mounted vertically
with inlet up and on a flat surface in an accessible area.
Locate the valve in such a manner that tubing used to
connect the valve to the bearings or nozzle is kept to a
minimum length. Divider valves have four 0.281 inch
(7.14 mm) holes for mounting with 1/4-20 or 6 mm
screws. The holes are hori zontally spaced 1.75 inches
(44.45 mm) apart. Vertical spac ing of mounting holes
varies with the number of divider valve sections. Use all
mounting holes to ensure the valve is secure.
2.2.5.2
In some applications more than a single divider valve
may be used. Divider valves which are supplied lubricant
directly from the pump or header line are referred to
as mas ter or primary divider valves. Divider valves
which receive lubricant from a primary divider valve are
referred to as sec ondary divider valves. Installation is
identical for all divider valves. Generally, divider valves
supplying Spindl-Gard com ponents are primary divider
valves. Secondary valves are usually designed to provide
lubricant to terminating bearing points on the system.
Cycle switches or proximity switches can be installed
on each secondary divider valve assembly for expanded
monitoring and ease of troubleshooting.
2.2.6
Pump Package and Header Installation
2.2.6.1
For all systems, the pump package should be securely
mounted in an accessible location. Enough clear ance
should be present to allow personnel to refill the reser-
voir without removal of any components.
2.2.6.2
For systems which use a pump-fed header, the header
line should be angled slightly upward from the pump
to assist in bleeding operations (see Figure 2-5). It is
recom mended that a needle valve be located at the
highest point of the header line to allow for easier air
bleeding.
2.2.7
Pneumatic Control Package Installation
2.2.7.1
The air requirements for spray nozzles are 15 psi (1
bar) with 40 ºF (4.4 ºC) dew point. Air must be filtered
to 5 microns to avoid contamination. Each spray nozzle
utilizes 0.6 scfm (17 sclm) of air.
2.2.7.2
Air preparation packages should be mounted as close as
possible to their corresponding components in order to
minimize air line lengths. Excessive air line length could
result in pressure drop and erratic operation.
