The air resource triple-assy XFRU403 is composed by filter, pressure release, oil
atomizing as shown by A
、B、C in the assembly drawing.
A- Adjusting screw is used to adjust the oil amount
B- Filling aperture bolt. When oiling, cut off the air source first, then screw off the B, after
oil adding, tighten the B, and ensure the seal.
C- For handwheel of pressure adjustment, normal stepless adjusting range is of
0.1~0.6.When adjusting the pressure, first, push the C upward vertically to the required
pressure, then press down it directly to lock the handwheel C in order to keep the
pressure stable. Manual reversing valve P is connected with air source triple-assy,
chamber A is connected with the inlet hole of single-way throttle, chamber B
connected with the small control cave of the cylinder, and R is connected with the
deafener.
Compressed air comes into the manual reversing valve through the triple-assy, then goes
into the single-way throttle through chamber A to push the cylinder tightening the
workpiece slowly, and the tightening speed is adjusted by the single-way throttle. The air
in the small cylinder goes into the deafener through the manual reversing valve, then
exhausted out.
When the position of the manual reversing valve is changed over, the air comes into the
small cave of the cylinder through the manual valve Chamber B, the cylinder moves to the
right quickly to release the tailstock.
The air in the big chamber comes into the manual reversing valve through the single-way
valve of the single-way throttle, and exhausted out through the deafener to finish the
action of tightening and releasing.
 Matters needing attention
The oil used for oil atomizer (the air-source element) must be very clean and be added
in time.
The convenience of adding oil should be considered when fitting the pipe.
The oil shouldn’t be filled too much, and otherwise, the effect of air pressure will be
lost.
The nylon pipe without burr should be inserted into the rabbet and put it to the end to
reach the requirement of connection and seal.
When the air pipe is removed, press in the connecting clip set with the thumb, and then
push out the air pipe slightly.
