Working Principle of Heat Treatment Vacuum Furnace


Vacuum furnaces are industrial furnaces heated by electrothermal elements in the near vacuum state. They are mainly used in ceramic firing, vacuum smelting and degassing annealing of electrovacuum parts.
The working principle of vacuum furnace of heat treatment equipment is to form a low-pressure environment with little air by extracting vacuum, and then to produce steam by boiling water at low pressure (below atmospheric pressure). The principle of heat output by condensation heat transfer of steam and water works.
Vacuum Furnace for Heat Treatment Equipment
Compared with other types of furnaces, vacuum furnaces have several distinct advantages:
(1) The environment will not be polluted and there is no need to treat the three wastes.
(2) Due to the use of high-quality insulation materials to make insulation walls and barriers, energy consumption is low and energy saving effect is remarkable;
(3) High accuracy of temperature control.

Reasons for Axis Breakage of Water Ring Vacuum Pump and Corresponding Measures

图片
Axis Breakage of Water Ring Vacuum Pump: After 2 years of use, water ring vacuum pump will present the phenomenon of excessive noise, excessive starting current, remarkable decrease in pumping capacity and vacuum degree. It is found that the scale inside the pump body is severe after the technical staff of our company disassembled and inspected. The reason for scaling is that the water contains calcium, magnesium and other carbonate substances. When the pump is heated and heated, its solubility decreases, and molecule-bound deposits form scales. What measures should be adopted to avoid axle breakage? Water ring vacuum pump Through the analysis of the causes of shaft breakage of water ring pump, the following corresponding measures are adopted. 1. Revamping the original process equipment to reduce the content of impurities in acetylene gas trap: At the same time, the large well water of water ring vacuum pump is changed into circulating water to reduce the hardness of wat
