Vacuum oven high temperature drying oven

---

The vacuum furnace parts and components are composed of main engine, furnace chamber, electric heating device, sealed furnace shell, vacuum system, power supply system, temperature control system and transportation vehicle outside the furnace. Today we will talk about the high temperature system of vacuum high temperature drying oven.

Welding is a major process in the high temperature system production, in order to ensure that the weld does not leak after welding, in addition to the request of skilled workers to carry out welding, improve the quality of welding, reasonable planning of welding structure is also very important. Therefore, the welding structure should avoid the open space of accumulated dirt in the welding seam at high temperature, otherwise it will be difficult to clean the formation, and will also become the gas source of slow air discharge. When the weld appears dead space, it is not easy to find the slot in the system leak detection.

Multiple flanges are connected between the components of the high temperature system. The flange is welded to the pipe. Since it is easy to cause flange deformation during welding, it is currently used in China to process the flange after welding, so as to meet the requirements of size and roughness, and to ensure that the two flanges are sealed firmly when connecting.

Cut the exterior air vent. The higher the surface roughness of the components and the inner wall of the shell is, the better. Electroplating polishing, oxidation treatment, etc. The inner wall roughness at high temperature is usually 6.3/ ~ 3.2/; The inner wall roughness at medium to high temperature is at 12.5/ push. At high temperatures the inner wall roughness is required to be polished to a very shiny appearance. Special attention should be paid to: the appearance of rusty metal is very bad for leisure!

The organization of the measurement control seat on the high temperature system should follow the following criteria:

A. do not place measurement controls in areas with a high number of sealing surfaces. Because each sealing surface can not ensure that no leakage, sealing surface gathering place, must be a simple leakage of the local, measurement value may be banned.

B. It is necessary to ensure high temperature cleaning when the inner wall of the regulation is all over the place. Otherwise it will form a measurement ban.

C. The regulation should be as close to the measured area as possible to reduce measurement errors.

The water jacket structure on the shell of the vacuum furnace high greenhouse, to ensure the flow of water unobstructed, can not let the local water form part of the phenomenon of overheating, so in and out of the direction of the water pipe to a up, set the water layer.
