introduction：The rotation principle of the motor is based on Flemings left hand rule，When a wire is placed in a magnetic field，If the wire is running current，The wire will cut the magnetic field lines causing the wire to move。 An electric current enters the coil and creates a magnetic field，Using the magnetic effects of electric currents，A device for continuous rotation of an electromagnet in a fixed magnet，Electrical energy can be converted into mechanical energy。 Power is generated by interaction with a permanent magnet or a magnetic field generated by another set of coils Dc motorThe principle is that the stator does not move，The rotor moves in the direction of the force generated by the interaction。 The AC motor is the stator winding coil through alternating current，Generate a rotating magnetic field，A rotating magnetic field attracts the rotor together for rotating motion the basic construction of a DC motor includes“armature”、“Field magnet”、“Collector ring”、“Electric brush”。 armature:Multiple coils can be wound aro

introduction：A pneumatic conveying device that uses the static pressure of air to press or suck a container containing material in a pipe。1861years﹐The post Office in London built the first practical line of container piping。thereafter﹐In Berlin﹑Paris﹑Cities such as Vienna and Munich have also built such conveying devices﹐For post office﹑bank﹑Hospitals and libraries carry mail﹑Summons and sample。Because the transport container is small﹐In the shape of a small bucket﹐This conveying device is also known as the air delivery bucket。After solving technical problems such as the impact of large containers when they stop and the manufacture of pipes﹐Federal Germany1964A pipe with a diameter of 450millimeter﹑The container is equipped with running wheels at both ends﹑Conveying distance is2200The utility line of the pressure feed type pipeline conveying device。70age﹐The Soviet Union﹑The United States and Japan have also built large container-type pipeline transportation devices。This conveyer has low operating costs﹐Safe and reliable

introduction：There are many flow meters used to measure the flow of dirty water and clean water on large diameter pipes，But each has its own strengths and weaknesses。In measurement，Some flow meters are wound by debris because of the moving part，As a result, its accuracy decreases，Cant even use。Some are covered by debris due to a certain use element inside the instrument，Normal sending of messages is affected，Some are affected by scale，At the same time, the flowmeter of the large pipe is too heavy，Installation and transportation are extremely inconvenient，And its expensive.，energy-intensive，meanwhile，Some current meter users are not easy to master the use and maintenance technology，Difficult to popularize。The plug-in ultrasonic flowmeter and electromagnetic flow calculation solve these problems well。
