What causes the temperature of Puxu vacuum pumps to rise excessively??
Recently, Germany's Dr.-Ing. K. Busch GmbH has launched its new R 5 series vacuum pumps to the public for the first time. These vacuum pumps are suitable for various types of packaging equipment, from small machines to large rolling machines, significantly reducing the time required for the packaging process.

The new Busch R 5 vacuum pump achieves higher vacuum levels, reducing packaging time and increasing its suction capacity by 50% compared to the original scroll vacuum pump. Busch currently offers a range of suction capacities from 25 to 1600 cubic meters per hour.

Rotary vane vacuum pumps are the most commonly used vacuum pumps in domestic industrial applications, with a broad range of applications across various industries, especially in vacuum packaging. In fact, vacuum packaging technology in China only began to take root in the 1940s. The advent of plastic films greatly accelerated the overall development of the vacuum packaging industry in our country. Today, to better meet market demand, the technology of vacuum packaging machinery is advancing, particularly driven by the rapid development of the food industry, leading to the intelligent and high-speed development of vacuum packaging equipment in China.
Scroll vacuum pumps can remove dry gases from sealed containers, and with an attached gas trap, they can also remove a certain amount of condensable gases. However, they are not suitable for removing gases with high oxygen content, corrosive to metals, reactive with pump oil, or containing particulate dust. The relationship between the pumping speed of the scroll vacuum pump and the inlet pressure is specified as follows: at an inlet pressure of 1333 Pa, 1.33 Pa, and 1.33×10-1 Pa, the pumping speed values must not be less than 95%, 50%, and 20% respectively of the pump's nominal pumping speed.
In fact, the application of domestic vacuum packaging technology extends far beyond the food industry. Lately, with the widespread use of vacuum bags, the industry has successfully expanded into fields such as electronics, fibers, automotive, and oil, thanks to its strong protective, isolating, and airtight properties, opening up a broader space for further development across the entire sector.
China's vacuum packaging technology continues to advance,迎来 another sunny day for scroll vacuum pumps.
