Saburo: Hey, Mitsuwa Man. I read a book the other day that had a "time machine" in it. Do pumps and time have any relation? Mitsuwa Man: That's a good question! Of course, pumps and time are very deeply related. Saburo: But a pump is a machine that moves water, right? How is it related to time? Mitsuwa Man: First of all, a pump requires energy to operate. That energy is supplied by motors or engines, but what's important is how much water is moved in a certain "time." This is called "flow rate." *For more details, you can view the related links.

Saburo: Mitsuwa Man, I learned about "centrifugal force" at school, but does this have anything to do with pumps? Mitsuwa Man: Good question! Actually, centrifugal force is one of the important principles of pumps, especially centrifugal spiral pumps. A centrifugal pump works by a component called an impeller rotating and pushing the liquid out. Saburo: What does an impeller look like? Mitsuwa Man: An impeller looks like the blades of a fan, kind of like a small windmill. By rotating, it sucks in the liquid and pushes it out. Then, that liquid passes through the pump, gradually losing speed and converting into pressure. *For more detailed information, you can view the related links.

In the manufacturing industry, a quiet wave of transformation is currently sweeping in. This time, I will talk about ABB (Asea Brown Boveri), a company headquartered in northern Switzerland, and its advanced initiatives, as well as the future of the manufacturing industry as seen from there. ABB was founded over 100 years ago in 1891. It is a large company with 140,000 employees that has been manufacturing industrial equipment made of iron. Since 1954, it has started producing large components known as circuit breakers, and now it boasts a 70% market share as a top company. This traditional manufacturing company is now undergoing transformation. *For more details, you can view the blog through the related links.

In industrial plants and manufacturing sites, various types of water are used. Among them, there are "liquids that will solidify if not constantly stirred" and "liquids that need to be continuously mixed to prevent components from settling." In such cases, stirrers are often used, but many people seem to face challenges such as "high electricity costs" and "the need for regular maintenance, which increases costs." Therefore, this time we will introduce a method that may reduce costs. *For detailed content of the column, please refer to the related link.

Saburo: Ah~. Golden Week is over. It's a long wait until the next summer vacation~. Mitsuwa Man: When the holidays are fun, it can also make you feel a bit down. June is the rainy season, so it might be a time when you feel a bit gloomy because of all the rain. Saburo: I see! There's also the rainy season! I don't like that~... Oh, can't we send the rain somewhere with a pump?! Mitsuwa Man: That's a good idea! While we can't stop the rain, pumps are used to send rainwater to other places after it falls. It's designed to flow naturally from the gutters on the road to specific locations, but pumps are used to adjust the amount of water collected in those areas. If we leave it alone, the rainwater would overflow. *For more details, you can view the related links. For more information, please refer to the PDF materials or feel free to contact us.*

Saburo: Hey Mitsuwa Man, recently Mom has been saying "I need to go on a diet," but what is a diet? Mitsuwa Man: A diet means reducing body weight. People go on diets to maintain their health, and specifically, it often involves making adjustments to diet and exercise. Saburo: Oh, I see. Does the pump do something like a diet too? Mitsuwa Man: Actually, it does! While the term diet strongly implies reducing weight, it ultimately also means using energy efficiently. So, the pump is doing something similar to a diet in the sense of using energy efficiently rather than just reducing the weight of the machine. *For more details, you can view the related links.
