Vacuum Testing Unit
60,000 - 80,000 Per Piece
The molten sample is kept under vacuum for about 2 minutes, and residual gas inside the sample is indicated on the upper surface of the sample as well as very prominently indicated as blow holes when the sample is cut/machined. The size & the number of blow holes will depend on the gas content of the sample. Technical Details Vacuum Pump – A high vacuum pump, driven by a 0.5hp single phase motor. Vacuum Regulator – From feedback received from various users, it was found that various alloys require different level of vacuum. This can regulate the vacuum from 500 to -760mmHg (Effective range for vacuum sampling normally is between -630 and -760mmHg). Control Panel – Over- load protection for the motor is provided. Various LED indicators are mounted on the panel. The vacuum indication is thru a digital display & vacuum sensing is done by a vacuum (pressure) transmitter. Vacuum Chamber – The main component of this machine, so designed as to withstand high vacuum as well as to attain vacuum merely on closing the lid without any clamping required. The spherical chamber comprises of two hemispheres of SS -304. Each hemisphere is of a single piece.
