Vacuum Oil Quenching Furnace Sold

A device that passes heat from a cold body to a high-temperature water through a medium. The heat pump device can make the medium (the cold medium) phase change and become lower than the cold reservoir, thus spontaneously absorb the heat of the cold reservoir. After returning to the compressor, the medium is compressed into high temperature (higher than the high temperature water) and the high pressure gas, which will spontaneously heat up to the hot reservoir. The heat transfer from a cold reservoir to a hot reservoir is realized.

When an uncondensable gas is produced inside the vacuum oil quenching furnace, the pressure increases, which is known as vacuum destruction. The influence of the non-condensable gas generated inside the vacuum oil quenching furnace is serious. When no non-condensable gas volume content of 0.2%, thermal efficiency is lower 20 ~ 30%, the water temperature increase will not come, reduces the boiler output, so the operation of the vacuum oil quenching furnace, must take no non-condensable gas extraction.

For gas quenching furnace, suit to deal with a higher hardenability materials of small (e.g., 35 crmnsi small) and high hardenability of material artifacts, oil quenching furnace application than the former is relatively wide, the highest because of high pressure gas cooling rate is smaller than the cooling speed of quench oil a lot; But the operation and maintenance of gas quenching furnace are simple compared with the latter.
