PM-150M - PTA system for manual surfacing |
|
|
The PM-150M system is designed
for manual PTA surfacing of different parts to hardface
and protect them against wear corrosion, cavitation
etc.
The PTA torch operates only with plasma transferred
arc which burns between a non-melting tungsten electrode
and work piece.
It is possible to deposit Fe-, Ni-, and Co- based
alloys on working and faceplate surfaces.
Pure argon is used as a working gas. There is an
optional ability to use a gas mix (argon + 5% hydrogen)
for the shielding improvement. The operating conditions
of the system (argon or gas mix usage) assigns by
operator with the aid of the PLC.
PM-150M system designed on mobile truck.
PM-150M system especially effective for surfacing of complicated curvilinear
surfaces in handicraft job-shop industry, machinery
parts renewal or new one production.

The control system of PM-150M designed on a PLC.
Due to availability of the PLC it is possible to use PM-150M as an automatic system.
For this purpose additional machine PTA torches are provided.
PM-150M PTA system adapted for hardfacing of diesel valves with using of PP-7 PTA torch
At the photo you can see the PM-150M adapted for hardfacing of diesel valves in automatic mode.
The PTA torch with mechanical oscillator is installed on stand with capability of vertical moving.
Length travel of the PTA torch is provided by the oscillator carriage in range of
100 mm.
It is possible to hardface with this equipment faceplate, cylindrical and conical surfaces of different outsize parts.
Control all mechanisms is provided from one remote-control station.
