The closed container is evacuated by a micro vacuum pump, and a tube is taken from the container to pump water. This method of indirect pumping with a micro vacuum pump is common. What factors will affect the speed of pumping?
First, the pumping speed of the pump, that is, the flow rate. This factor is well understood. The faster the pump draws, the faster the container creates a vacuum and the faster the water can flow into the container.
Second, the vacuum of the pump. The better the vacuum of the pump, the less gas remaining in the closed container, the thinner the gas, the greater the difference in air pressure between the container and the external environment, the greater the pressure on the water and the faster the flow. This is easily overlooked by most people.
Third, the size of the container. The larger the container, the slower the vacuum is formed, and the longer the vacuum is reached, the slower the water absorption rate.
Mainly the above three factors restrict the indirect pumping speed. There are of course other factors, such as the length of the tubing, the size of the bore, the resistance of the gas path and the fluid path components, etc., but these factors are generally fixed.
It is easy to be misunderstood by many people. It is thought that the container must be disconnected from the external water source. First, let the closed container form a vacuum and then open the water inlet pipe to pump water. In fact, it is not necessary to do this unless the container is large, the flow rate and vacuum of the vacuum pump. Very low. Our test found that for containers below 3 liters, with our VMC6005 and PK5008 pumps, almost every time the pump is energized, water begins to flow into the container. (ZX20110117)

Red Ginseng is widely used in daily life. It can be sliced in the mouth for a while, chewed, brewed tea, swallowed after grinding, or swallowed.
Fried soup, stew. Among them, chewing is the simplest way to take it. Cut red ginseng into thin slices and take 2-3 slices and 3 grams or so in your mouth for a moment. Chew them carefully when saliva is abundant in your mouth. Or tea, cut red ginseng into thin slices, take 2 - 3 grams in a bowl or cup, add boiling water to brew, cover for 5 minutes, then take, chew and swallow the ginseng slices several times. When used at the end of grinding, the ginseng is ground into fine powder and swallowed every day. The dosage of red ginseng in this method is less, depending on the individual's physique, generally 1-1.5 grams per time.
