Rotary plate vacuum pump in chemical catalysis industry


Application of rotary vane vacuum pump in chemical catalysis industry
Adsorption and desorption tests are commonly used in chemical catalytic characterization, which generally need to be analyzed in a high vacuum environment. Rotary vane vacuum pump is widely used in chemical catalysis industry.
Catalytic chemistry has a profound influence on the development and progress of human society. More than 80% of the traditional chemical processes are related to catalytic action. In recent years, the role and status of catalytic chemistry have been further evaluated with the attention of human beings to energy, environment and health. Therefore, it is necessary to master some knowledge about catalysts and catalytic processes.
Chemical adsorption apparatus is an important instrument for dynamic temperature programmed research, it can be the catalyst for TPD, TPO, TPR, TPS, TPSR research, in order to the product of the generated in the process of temperature programmed a detailed qualitative quantitative analysis (i.e., in order to distinguish and detect the kinds of escaping gas), often need and online mass spectrometry. Tpd-ms, as a new on-line analytical method, can be used in the analysis of the components and contents of desorption efflorescent gases. Punnock rotary vane vacuum pump has been widely used in the field of chemical catalysis.
Rotary vacuum pump research and development, production and provide perfect vacuum system solutions, has been serving the world's top 500 enterprises and well-known Chinese universities and laboratories, products sold throughout the country, is currently China's application in the aerospace field, pharmaceutical, medical, nuclear industry leading brand.

Reasons and Solutions for Fragile Belt of Roots Blower

图片
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
