Purpose and function of vacuum pumping in tubular furnace

Tube furnace is mainly used in metallurgy, glass, heat treatment, lithium anode and cathode materials, new energy, abrasives and other industries, measuring materials under certain temperature conditions of professional equipment. The furnace structure is simple, the operation is easy, the control is convenient, and the continuous production can be realized.

The tubular furnaces are all new type electric furnaces with high performance and energy saving, which are developed by the international Xian technology. There are a variety of tubular furnaces, such as single tube, double tube, horizontal, openable, vertical, single temperature zone, double temperature zone, three temperature zone, etc. It is mainly used for experiments and small batch production in Colleges and universities, scientific research institutes, industrial and mining enterprises, etc. The utility model has the advantages of safety and reliability, simple operation, high temperature control accuracy, good heat preservation effect, wide temperature range, high furnace temperature uniformity, many temperature zones, optional atmosphere, vacuum furnace type, etc.

Let's talk about the purpose and function of tube furnace vacuum pumping?

In order to improve the precision of vacuumizing, we first summarize the purpose and function of vacuumizing in the lower tube furnace. First, the purpose of vacuumizing is to reduce the air inside the tube furnace and make the test material out of an oxygen-free environment, so as to eliminate the redox reaction of the test material.

Why is vacuum low? Why can't the experiment reach the ideal state?

There are several problems in low vacuum degree;

First, the vacuum pump is aging, and the original vacuum degree is low;

Second, the vacuum pipeline is aging, the pipeline leaks, and the interface position leaks;

Third, the sealing ring of the tubular furnace is aging and the installation method is not correct.

The solution is as follows: first, replace the aging pipeline and sealing ring, and check whether there is air leakage at the interface position. In particular, many manufacturers use the quick connect air pipe interface which fails to meet the requirements of vacuumizing, which causes invisible air leakage and is not easy to check. Secondly, apply vacuum silicone grease on the sealing ring to improve the sealing performance of the sealing ring position, and focus on the sealing effect of the sealing ring installed at the flange position.
