Method and principle of use:1. When using, assemble the instrument according to the figure, shake the handle up and down, if it is not flexible, apply a little lubricating oil on the piston ring.2. Then add water about two-thirds of the depth of the sink into the sink, shake the handle, and the water is continuously pumped up and out of the water outlet.principle:When the piston moves upward from the lower fulcrum, due to atmospheric pressure, the water in the tank is sucked into the cylinder through the water inlet valve. After the piston reaches the upper fulcrum, the water absorption stops. Then, the piston moves from top to bottom. Under the action, the water inlet valve is closed, the water outlet valve is opened, and the water enters the upper part of the cylinder through the small hole of the piston. When the piston moves to the lower fulcrum and then moves up, the water inlet valve opens, sucking water, and the outlet valve closes at the same time. Water overflows from the spout.Maintenance and precautions1. Do not contact plastic products with organic solvents to avoid damage.2. After use, it should be cleaned and dried and stored properly to prevent the metal parts from rusting.

• Purpose: Pump model is used for middle school physics teaching demonstration and group experiment. It is mainly used to explain the structure and principle of suction or water trap.
• Principle: When the piston moves upward from the lower fulcrum, due to the effect of atmospheric pressure, the water in the water tank is sucked into the cylinder through the water inlet valve. After the piston reaches the upper fulcrum, the water absorption stops and the stopper moves from the top to the bottom. Under the action of pressure, the water inlet valve is closed, the water outlet valve is opened, and water enters the upper part of the cylinder through the small hole of the piston. Wh
• Use: Assemble the instrument as shown in the figure, without shaking the handle. If it is not flexible, apply a little oil to the piston ring, and then add about two-thirds of the depth of the water tank to the water tank and shake the handle. It was continuously pumped up and out of the spout.
