PRINCIPLE:
Oil intensifier works
on the same principle as that of a hydropneumatic double acting
intensifier. The power source is low pressure oil instead of pneumatic
power.
ADVANTAGES:
Oil intensifier
gives a high pressure output without the oil heating problem.
It uses low pressure oil as the power source and achieves intensification
by static pressure conversion.
Versions:
Two models are available with
intensification ratios 4 and 6. If the oil output of an intensifier
is sufficient for clamping- elements, the circuit as shown in
fig. 1 can be used. If the oil requirement of clamping-elements
is more than the output of an intensifier, then the prefill circuit
can be used as shown in fig. 2. By removing the make-up oil bottle,
the same port is used for prefilling.
Leakage compensation:
For fig. no. 1, make-up oil
bottle works in the same way as in hydropneumatic intensifier.
For fig. no. 2, prefilling circuit takes care of the leakage compensation,
and hence the make-up oil bottle is not required.
