Embodiment Construction

[0025]The technical solutions in the present invention will be further described below with reference to the accompanying drawings and examples.

[0026]Such asFigure 1-8As shown, the embodiment of the present invention proposes a multifunctional pump principle teaching presentation device, including water tank 10, water pump model, channel 11 and water pipe 7, water in the water tank 10 can flow into the water pump model through channel 11, and in the water pump Water can be returned to the water tank 10 through the water pipe 7. When the device is used, the water in the water tank 10 can enter into the water pump model through the channel 11, and the water in the water pump model can be reflowed to the water tank 10 through the water pipe 7 to achieve the action of the presentation.

[0027]Such asFigure 8 As shown in the schematic diagram of the reciprocating pump, the water pump model includes a pump main body 100, a second shutter plate 101, a third shutter plate 102, a piston 103, a...

Abstract

The invention provides a multifunctional pump principle teaching demonstration device. The device comprises a water tank, a water pump model, a channel and water pipes, water in the water tank can flow into the water pump model through the channel; water in the water pump can return to the water tank through the water pipe; the water pump model comprises a pump main body, a second flashboard, a third flashboard, a piston, a pull rod and a fixed plate; a glass plate is fixedly connected to the pump main body; a second flashboard and a third flashboard are arranged in the pump main body; the third flashboard is located above the second flashboard, the piston is located between the second flashboard and the third flashboard, the pull rod is fixedly connected to the piston, a fixing plate is further fixedly connected in the pump body, the water tank is placed on a mounting plate, the channel is formed in the mounting plate, and the water in the water tank can flow into the pump body through the channel. In the implementation process, a user can conveniently demonstrate the pump principle, and the user can conveniently assemble and disassemble the pump main body.

Description

Technical field[0001]The present invention relates to the field of teaching demonstrations, and more particularly to a multi-functional pump principle teaching presentation device.Background technique[0002]There are many kinds of reciprocating pumps, and the reciprocating pump has a very important role in people's daily lives, but the reciprocating pump on the market is large, and due to cost, the reciprocating pump is generally made of steel components, so When teaching demonstrations, people are difficult to accurately demonstrate the principles of complex pumps, and increase the difficulty of users.[0003]The working principle of the reciprocating pump is that when the pump is used, the pressure is poor, thereby inhaling the water into the pump main body. When the pressure is different, the water in the pump main body will be launched, so reciprocated use Thus water improves water.Inventive content[0004]In the prior art, the present invention provides a multi-function pump princip...
