Abstract
The invention discloses a buoyancy experimental facility for physics teaching. The buoyancy experimental facility for physics teaching includes a liquid storage barrel and two charge pumps, wherein a liquid adding opening is arranged at the middle position of the top surface at the upper end of the liquid storage barrel; a movable plate is arranged on the liquid adding opening and is used for controlling opening and closing of the liquid adding opening; the two charge pumps are respectively arranged at two sides of the top surface of the liquid storage barrel; the lower ends of the charge pumps are fixed on the top surface of the liquid storage barrel through a fixing base; a ball float is arranged in the liquid storage barrel; the upper end part of the ball float is connected with the charge pumps through a flexible pipe; liquid storage tanks are respectively arranged beside the two charge pumps; the two liquid storage tanks are internally provided with materials with different concentration; scale marks are arranged on the liquid storage barrel; and the middle part of the soft tube is provided with a segment of telescopic structure. As two charge pumps are arranged on the liquid storage barrel and the liquid storage tanks are respectively arranged beside the two charge pumps, the buoyancy experimental facility for physics teaching can perform contrast experiments aiming at different situations at the same time, thus simplifying the experimental process; and as the liquid adding opening is arranged at the top surface of the liquid storage barrel and the length of the liquid adding opening is greater than the width of the ball float, an operator is convenient to take and put the ball float and can clean and change the ball float at regular intervals.
