The difference of three vacuum systems of vacuum tube furnace

Vacuum tube furnace energy - saving ceramic fiber material and double - layer shell structure, with high lifting and cooling speed and low energy consumption. The outer temperature can be reduced to normal temperature and the inner cavity temperature can be evenly distributed. High quality heating element, long service life. The following is a series of Shanghai Guier machinery to introduce the three vacuum tube furnace vacuum system of the relevant knowledge of the difference.

Vacuum tube furnace

Since there are many types of vacuum tube furnace, and each vacuum system of vacuum tube furnace has different requirements, so as far as the vacuum degree is concerned, there are three systems: low vacuum, medium vacuum and high vacuum. The differences between the three vacuum systems are described in detail.

1. Low vacuum system

The low vacuum system of the vacuum tube furnace is suitable for the vacuum tube furnace with the planned vacuum degree in 2-1333PA, such as the pre-pumped low vacuum well furnace, mostly oil seal rotary mechanical pump as the main pump.

2. Medium vacuum system

The medium vacuum system is suitable for the vacuum tube furnace with the planned vacuum degree of 3x10 -- 1.333Pa. The medium vacuum system is widely used in the vacuum tube furnace and generally consists of a two-stage vacuum pump unit. Primary pump rotary mechanical pump or valve type mechanical pump, the main pump for mechanical booster pump or oil booster pump.

3. High vacuum system

The high vacuum system is suitable for the vacuum tube furnace with 6.6x10 -- 1.333x10 pa program, such as vacuum annealing furnace and vacuum brazing furnace. Generally composed of three vacuum pump unit, main pump generally choose oil lax pump, ion pump, primary pump is mostly choose rotary machinery or sliding valve mechanical pump.

Vacuum tube furnaces are of periodic operation type. For laboratory, industrial and mining enterprises, scientific research units for element analysis and determination and general small steel pieces quenching, annealing, tempering and electronic ceramics and other new materials.
