What are the uses of vacuum pumps?

Everyone may have heard of the vacuum pump, but they are not very familiar with it. Some people even don't know what the vacuum pump is. The vacuum pump works efficiently and stably. The function of the vacuum pump is to remove gas molecules from the vacuum chamber and reduce the gas in the vacuum chamber. Pressure to make it reach the required vacuum degree.

Effective Countermeasures to Improve the Sealing Performance of Screw Vacuum Pump

Effective Countermeasures to Improve the Sealing Performance of Screw Vacuum Pump

Screw vacuum pump has become one of the important equipment in the field of machinery manufacturing, automobile and other fields with its own advantages of low noise and energy saving, and plays an active role in improving work efficiency. However, due to many factors, the sealing performance of screw vacuum pump is poor, which directly affects the ability of screw vacuum pump. It is of positive significance to strengthen the research on the factors affecting the sealing performance of screw vacuum pump.

Requirements to be followed when selecting vacuum pump oil

Requirements to be followed when selecting vacuum pump oil

The pump oil in the vacuum pump accessories should have a suitable viscosity, which can make the vacuum pump start quickly at low temperature, and the pump oil can have good sealing performance at high temperature, and the pump oil has a low temperature rise. Does not contain light volatile components, reduce the use of the process of vacuum pump oil return rate.

Zhixuan Technology | The secret of cost reduction and efficiency increase in small shed farming turns out to be it...

Shrimp farming in a small shed is an efficient production model. Shed shrimp using circulating aquaculture technology, can save water resources, reduce environmental pollution. At the same time, controlling the light, temperature, water quality and other environmental conditions in the small shed can accelerate the growth rate of shrimp and improve the yield and quality.

Vacuum pumps are widely used in the coating industry and coating equipment.

Vacuum coating technology is an important branch of vacuum application technology, which has been widely used in optics, electronics, energy development, physical and chemical instruments, construction machinery, packaging, civil products, surface science and scientific research and other fields. The main methods used in vacuum coating are evaporation plating, sputtering plating, ion plating, beam deposition plating and molecular beam epitaxy. In addition, there is a chemical vapor deposition method. If the purpose of vacuum coating is to change the physical and chemical properties of the surface of the material, this technology is an important part of vacuum surface treatment technology.

Technological innovation is the key to the core competitiveness

Technological innovation is the key to the core competitiveness

After the harvest of fruits and vegetables, life is not over, there is still respiration, that is, to absorb oxygen, carbon dioxide and water. In the process of metabolism, a large amount of respiratory heat is produced, so that nutrients are continuously consumed and a large amount of water is lost. As a result, fruits and vegetables wither, change color and soften, and reduce vitamins, resulting in deterioration and loss of commodity value. The only way to weaken the respiratory intensity of fruits and vegetables is to quickly reduce the temperature of fruits and vegetables to reduce their respiratory heat. Low temperature can not only inhibit the growth and reproduction of microorganisms, but also inhibit the activity of enzymes in food, delay the change of chemical composition in fruits and vegetables, and maintain the nutritional value and color, aroma and taste quality of food. The quality of fruits and vegetables can be improved by proper treatment after picking. Vacuum pre-cooling is considered to be an effective method to slow down the ripening of fruits and vegetables after picking and to ensure food quality.
