goes through a mechanical trap condenser before
entering the atmosphere. The condensed liquid will be let out manually.
3.5 The vacuum valves used are of high vacuum pneumatic ones.
3.6 intelligent digital magnetic resistance vacuum meter, and absolute pressure
3.7 electrical contact vacuum meter, electrical contact pressure gauge.
3.8 circulation water tank, pump, valves and pipeline.

indicating the whole processing process. Store them in the form of time-pressure
and parameter curve on the computer hard disk. Keep records for a long time.
They can be inquired and printed at any time, and output user information in the
form of table (impregnation process parameters, time, operator number,
part number, etc.).

occurs, it can be switched to manual operation. When vacuum degree or pressure
exists in the tank, the hydraulic system doesn’t work when the operator closes
the tank cover.
10.12 It has necessary mechanical and electrical interlocking and alarm functions.
Prevent overpressure and artificial wrong operation.
