introduction：leserSafety valve price The safety valve is in a normally closed state under the action of external force，When the medium pressure in the equipment or pipe rises beyond the specified value，A special valve that prevents the pressure of the medium in the pipe or equipment from exceeding specified values by discharging the medium outside the system。Safety valves belong to automatic valves，Mainly used in boilers、Pressure vessels and pipes，Control pressure does not exceed the specified value，It plays an important role in protecting personal safety and equipment operation。The injection safety valve must be tested before it can be used。

introduction：Three-phase induction motor(Triple-phase asynchronous motor)Its by simultaneous access380VThree-phase AC power supply（Phase difference120The degree of）A type of electric motor supplied with electricity，Due to three-phase asynchronous motorsThe rotor rotates the magnetic field in the same direction as the stator、Different speed into rotation，There is a slip，So its called three-phase asynchronous motor。 When the motors three-phase stator winding After the three phase symmetrical alternating current，Will create a rotating magnetic field，The rotating magnetic field cuts the rotor windings，Thus an induced current is generated in the rotor winding（The rotor winding is a closed path），The rotor conductor carrying current will generate electromagnetic force under the action of stator rotating magnetic field，Thus forming electromagnetic torque on the motor shaft，Drive motor rotation，And the direction of the motor rotation is the same as that of the rotating magnetic field.

introduction：smcSolenoid valve principle SMCThe solenoid valve has a closed chamber，Through holes are opened at different positions，Each hole leads to a different pipe，In the middle of the chamber is the valve，On both sides are two electromagnets，The magnet coil on which the valve body is energized will be attracted to which side，Different discharge holes are blocked or leaked by controlling the movement of the valve body，The oil inlet hole is always open，The hydraulic fluid goes into the different drain lines，The piston of the cylinder is then pushed by the pressure of the oil，The piston in turn drives the rod，The piston rod drives the mechanism。In this way, mechanical motion is controlled by controlling the current of the electromagnet。

introduction：Synchronous motor，And induction machine（Asynchronous motor）The same is a commonly used AC motor[1] 。Synchronous motor is the heart of power system，It is a set of rotation and rest、Electromagnetic changes are integrated with mechanical motion，A component that converts electrical and mechanical energy，Its dynamic performance is very complex，Moreover, its dynamic performance has great influence on the dynamic performance of the whole power system。The characteristic is：Steady running time，There is a constant relationship between the speed of the rotor and the frequency of the gridn=ns=60f/p，amongfGrid frequency，pIs the number of poles of the motor，nsCalled synchronous speed。If the frequency of the grid is constant，The speed of the synchronous motor in steady state is constant and has nothing to do with the size of the load。Synchronous motor is divided into synchronous generator and synchronous motor。The alternators in modern power plants are mainly synchronous generators。
