Heat treatment vacuum furnaces and atmosphere furnaces must be vacuum pumped. What kind of vacuum pump is most suitable? Industrial furnaces recommend the most suitable vacuum pump according to the actual production situation.
During the use of heat treatment vacuum furnace, according to the requirements of heat treatment vacuum furnace, the vacuum degree ranges from – 0.1Mpa to several Pa. The belt drive bipolar rotary vane vacuum pump is the most economical and economical one in actual production. If strict noise control is required, a direct-connected rotary vane vacuum pump can be used. Two-stage rotary vane vacuum pump and Roots vacuum pump can be used to form a unit when the vacuum degree of vacuum furnace is high. Very few vacuum pumps are required to be in series with diffusion vacuum pumps.

size
Vacuum pump size selection: heat treatment vacuum furnace vacuum pump size can refer to the extraction rate and furnace tank size to choose the appropriate size of the vacuum pump, because the vacuum furnace vacuum to meet the requirements of vacuum time usually do not require special requirements, size selection range is large.
Vacuum pump of heat treatment vacuum furnace is a two-stage oil seal mechanical vacuum pump. It is the basic equipment used to extract gas from sealed container to obtain vacuum. It is suitable for electronic, refrigeration, electric light source, chemical industry, hospital, bottle gall, packaging, dehydration, drying and other industries. But it can not be used to extract explosive, corrosive to metals, chemical reaction to vacuum oil and gas with particles and dust, nor can it be used as a conveying pump and compression pump.
