Pascal Ball Junior high School Physics Experiment Equipment Student Teaching aid Teaching aid Instrument

Purpose: This product is mainly used for middle school physics demonstration liquid to pressure transmission. Structure: At one end of the round tube, there is a metal sphere in the center of the chamber, and there are ten gas nozzles in different directions on the sphere. A piston is installed in the tube. The piston is composed of an oil-resistant rubber ring. The piston rod extends out of the cover and is equipped with a handle. Use: Unscrew the hollow ball, immerse the round slip into the water, lift the piston to absorb water under the round slip, fill the hollow ball with water, and spin the ball onto the cylinder in the water, and then lift the entire instrument out of the water and slowly press it down The piston and water are sprayed from the small holes of the nozzle to all directions, indicating that the liquid can transmit the pressure received in all directions. After the experiment, the instrument should be disassembled and wiped clean, assembled and preserved after air-drying, and the metal parts should be coated with a little lubricating oil to prevent corrosion., Manufacturer: ASumPio
