Vacuum pump for heat treatment vacuum furnace

What kind of vacuum pump is most suitable for heat treatment vacuum furnaces and atmosphere furnaces that require vacuum pumping? The most suitable vacuum pump for Chengchi Industrial Furnace is recommended based on the actual production situation.

During the use of the heat treatment vacuum furnace, according to the requirements of the heat treatment vacuum furnace, the vacuum degree ranges from -0.1Mpa to several pascals. In actual production, the use of belt driven bipolar rotary vane vacuum pumps is the most economical and practical. If strict noise control is required, a direct connected rotary vane vacuum pump can be used. When a high vacuum degree is required for a vacuum furnace, a two-stage rotary vane vacuum pump combined with a Roots vacuum pump can be used to form a unit. Very few require a vacuum degree that can be connected in series with a diffusion vacuum pump.

Vacuum pump size selection: The size of the vacuum pump for the heat treatment vacuum furnace can be selected based on the pumping rate and the size of the furnace tank. As the time required for the vacuum furnace to reach the required vacuum degree is usually not subject to special requirements, the range of size selection is relatively large.

The vacuum pump system for heat treatment vacuum furnaces is a two-stage oil sealed mechanical vacuum pump. It is a basic equipment used to seal containers and extract gases to obtain vacuum. It is suitable for industries such as electronics, refrigeration, electric light sources, chemical engineering, hospitals, bottle packaging, packaging, dehydration, and drying. (However, it cannot be used to remove explosive gases with high oxygen content, corrosive to metals, chemically reactive with vacuum oil, and gases with particles or dust, nor can it be used as a conveying pump or compression pump).
