The Vacuum Pump – How It Works and What To Look For
To retail or buy a vacuum pump , you’ll need to decide which type makes the most sense for your situation. A rotary pump generally produces the highest vacuum while a linear pump produces the lowest vacuum. The highest vacuum is created by replacing the air inside the chamber of your pump with a high-speed fan. More specifically, these pumps are popular for drawing blood into a syringe. This feature allows the volume of blood to be replaced much faster than other pumps which have slower rotational speeds (like the household dust collectors mentioned previously). Since low vacuum is important for removing blood from a vein, a pump with a high rotation speed is usually required to accomplish this. However, in vehicles (such as ambulances) or in medical chambers, a high-pitched, screaming fan may actually create more vacuum. Because of this reason, a supplemental fan is used to create a vacuum at higher speeds in order to achieve the same result as a faster pump. What this accomplishes i
