Vacuum furnace and vacuum thermos cup


Stainless steel vacuum cup has made great progress in China since the reform and development, especially in the past decade. Our company has developed more than 50 series of vacuum cups and pots, hundreds of varieties, is still in constant development, production, variety with each passing day.
Vacuum cups are simply divided into tailless vacuum cups (or holistic vacuum cups) with tailed vacuum cups according to their production methods. The tail vacuum cup is obtained by vacuum exhaust platform, similar to glass thermos bottle and large electronic tube. On the vacuum exhaust platform, vacuum cup is inserted (bottom of the vacuum cup is welded with exhaust copper pipe). When the vacuum is less than 2 *E23Pa, the copper pipe is cut and polished with hydraulic clamps, and then the following processes are carried out: painting, gluing, electrolysis, polishing, pressing and packing.
The tailless vacuum cup is formed in a vacuum brazing furnace by vacuum pumping, vacuum brazing, then cooling out, electrolysis, polishing, packaging and other processes (see Figure 2).
The length of holding time of vacuum cup depends on the structure of the cup and the thickness of the material.
The vacuum cup with large capacity and small caliber has a longer holding time, while the vacuum cup with large caliber has a shorter holding time.
The longer the material is, the longer the holding time is, but the cup body is easily damaged and deformed, which affects the service life.
3. The outer layer of metal film and copper plating inside the vacuum cup can also increase the degree of thermal insulation.
The service life of the vacuum cup also depends on the cleaning of the inner layer of the cup and the time of evacuation. The most important thing is the structure of the vacuum furnace. Nowadays, there are four kinds of vacuum equipments used in society, i.e. vacuum exhaust table and vacuum brazing furnace. The two category is the tail vacuum exhaust desk; another type of brazing furnace. The brazing furnace type is divided into single chamber, multi chamber, increasing pumping speed and multi chamber.

Reasons and Solutions for Fragile Belt of Roots Blower

1. Reasons for easily broken belt of Roots blower: 1. First of all, consider the high speed and high temperature of Roots blower. 2. The distance between the head and motor of Roots blower is too large and the belt is tight. 3. The belt does not match the V groove of the pulley, so it can not withstand the load fracture after wearing. 4. Active pulley and driven pulley are not parallel, resulting in serious friction between belt and groove on one side, and can not bear load fracture after wear. 5. Heavy load, long-term overload operation of belt is easy to break. 6. Roots fan nose and motor pulley are not concentric, different axes. 7. Belt quality problems. 2. Measures to prevent the belt of Roots blower from breaking. 1. Roots blower must start without load before running. After starting, it should be loaded. After running, it can generally avoid triangular belt breaking. 2. The pulley between the motor and the fan should be parallel, which is a key point. If not para
