What causes the vacuum pump motor to run hot?

1. The motor has high power, large operating current, and generates a lot of heat. 2. The fan speed is low, resulting in low air pressure and airflow. 3. The fan has fewer blades, producing a smaller amount of airflow.

Does air cause lubricating oil to deteriorate?

The lubrication system is a key part of various machinery and vehicles, and one of the maintenance essentials is to avoid introducing impurities. We usually pay attention to contaminants such as dust, particulate impurities, and moisture, but often overlook air. Air does affect the performance of lubricating oil. Although lubricating oil inevitably comes into contact with air, air mixed into the lubricating oil—such as foam on the oil surface or bubbles trapped inside the oil—can negatively impact lubrication. Generally, lubricating oil slowly oxidizes (reacts with oxygen) after exposure to air, but this process is relatively slow, unavoidable, and normal. However, if air enters inside the lubricating oil, it can cause significant problems.

Rotary vane vacuum pumps: operation and maintenance—summarized perfectly!

A vacuum pump refers to a device or equipment that uses mechanical, physical, chemical, or physico-chemical methods to evacuate a container and obtain a vacuum. Simply put, a vacuum pump is a device that improves, generates, and maintains a vacuum within a certain enclosed space using various methods. With the development of vacuum applications, many types of vacuum pumps have been developed, with pumping speeds ranging from a few tenths of a liter per second to hundreds of thousands or millions of liters per second. As vacuum technology's application pressure range requirements in production and scientific research fields become increasingly broad, most systems require a combination of several types of vacuum pumps working together to meet the demands of production and scientific research processes. Because the working pressure range involved in vacuum applications is very wide, no single type of vacuum pump can fully suit all working pressure ranges. Different types of vacuum pumps must be used according to different working pressure ranges and requirements. For convenience and the needs of various vacuum processes, different vacuum pumps are sometimes combined according to their performance requirements and applied as a unit.

Vacuum helps preserve food.

There are many ways to extend the shelf life of food. Among the oldest methods—smoking and pickling—one crucial step has always been drying, a technique that has been used for centuries before modern innovations like freezing, high-temperature cooking, or vacuum packaging. Today, advanced freeze-drying technology represents an improved version of traditional drying methods, using sublimation to preserve food quality over even longer periods. This process is only possible thanks to cutting-edge vacuum technology, as freeze-dried foods must be processed under vacuum conditions. FrostX’s compact freeze-dryer is perfectly suited for bakeries and restaurants, capable of freeze-drying a wide variety of fruits, vegetables, herbs, mushrooms, meats, and even ready-to-eat meals.

Vacuum assistance boosts production efficiency

Balkan cheese, Kashkaval cheese, and baked cheese—delicious varieties crafted daily by the Crailsheim-Dinkelsbühl Dairy Company, which processes 427,000 liters of raw milk to create its signature cheeses. Meanwhile, Busch vacuum systems ensure faster cycle times and more reliable production. In the production facility in Crailsheim, Baden-Württemberg, long "white ribbons" of cheese continuously glide past as workers expertly place the white cheese blocks into three adjacent cheese vats. Before the process moves on to vacuum sealing and cutting, each package is adorned with a layer of colorful foil. Meanwhile, a robot is busy assembling cardboard boxes, carefully using vacuum grippers to delicately position the freshly wrapped cheese pieces inside. Once packaged, these cheeses are labeled with either major brand names or store-exclusive labels—and then shipped off to supermarkets and discount stores across Germany for retail distribution.

Vacuum-assisted enhancement for a superior cooking experience

De Groene Olifant has expanded its range of dishes with the help of a benchtop packaging machine powered by a Busch R5 oil-lubricated rotary vane vacuum pump. The device enables vacuum low-temperature cooking and instant marination, while also reducing marination time and enhancing food preservation through optimized packaging.
