The vacuum tube furnace is no longer regenerated, and the basic style is the transitional working style. General industrial enterprises, laboratories, research institutes, etc. use vacuum vacuum ovens for annealing, quenching and tempering of small steel parts for heating.
Vacuum tube furnaces are general, but the vacuum system cannot be short. Generally, the vacuum system of the vacuum tube furnace should be equipped with: quickly pump the vacuum of the vacuum tube furnace to the regulatory requirements, and can clean the steel parts and Various gases released by the internal components of the furnace, and the vacuum unit has a small footprint, safe and reliable operation, and three requirements for short operation.
Since there are many types of vacuum tube furnaces, and each has different requirements for the vacuum system of vacuum tube furnaces, in terms of vacuum degree, there are three systems of low vacuum, medium vacuum and high vacuum. Let's talk about the differences between these three ultrafiltration devices in detail below.
1. Low vacuum system
The low cooling system of the vacuum tube furnace is suitable for vacuum tube furnaces with a superheat degree of 2—1333Pa. For example, the pre-pumped low vacuum pit furnaces mostly use tubing joint rotary mechanicalpumps as the main pump.
2. Medium vacuum system
The medium vacuum system is suitable for vacuum tube furnaces with a vacuum degree of 3x10—1.333Pa. The medium vacuum system is widely used in vacuum tube furnaces, and generally consists of a multi-stage vacuum pump unit. The primary pump is mostly a rotary mechanical pump or a sliding valve mechanical pump, and the main pump is a mechanical booster pump or an oil booster pump.
3. High vacuum system
The high vacuum system is suitable for vacuum tube furnaces with a vacuum degree of 6.6x10—1.333x10Pa, such as vacuum sintering furnaces and vacuum sintering furnaces. It is generally composed of a three-stage vacuum pump unit. The main pump is generally an oil dispersion pump, an ion pump, and the primary pump is mostly a rotating machinery or a sliding valve mechanical pump.
Do we know something about the ultrafiltration device of the vacuum tube furnace? We can take a look at it, and then choose the appropriate vacuum system based on our supply and demand.
