introduction:Rotary cylinder The rotating cylinder is mainly composed of an air guide head、Cylinder block、Piston and piston rod composition。When the rotary cylinder is working,External forces drive the cylinder、Cylinder head and air deflector turn,The piston and piston rod can only be used for reciprocating linear motion,And the external nozzle of the air guide head,immobile。With the continuous rapid development of automation machinery industry,More and more industries and different enterprises are using rodless cylinders,There are also more and more enterprises in the rodless cylinder industry to develop and grow。

introduction:Parker rodless cylinder With the continuous rapid development of rodless cylinders,More and more industries and different enterprises are using rodless cylinders,There are also more and more enterprises in the rodless cylinder industry to develop and grow。Parker rodless cylinder refers to the use of pistons directly or indirectly connected to the external actuator,And make it follow the piston to achieve reciprocating movement of the cylinder。The big advantage of this type of cylinder is that it saves installation space,Divided into magnetic couple rodless cylinder(Magnetic cylinder)With mechanical rodless cylinders。Each transmission component has its own transmission principle,The transmission principle determines his method of use and working environment,The following Feng Ye Xiaobian will take you to understand the principle of Parker rodless cylinder。

introduction:On maintenance,We should keep the air fresh,If its humid air,Or not clean,The consequences are serious。The moist gas decomposes into hydrogen,Oxygen mixture,That would create post-fracture insulation between the contact points,In severe cases, it can cause an arc chamber explosion。It makes the insulation less strong,A condition in which the surface gradually produces electrical discharge,So you cant touch it,In case of electric shock,The consequences can be imagined,So its better to be cautious。In addition,The pipes become clogged when they are being painted,The circuit will fail or even freeze。These are all caused by unclean air,Grossly inconsistent,so,The air should always be kept clean。

introduction:Reactive power not only increases line loss and equipment heating,More importantly, the reduction of power factor leads to the reduction of the active power of the grid,A large amount of reactive energy is consumed in the line,The equipment is used inefficiently,Serious waste,After using variable frequency speed regulating device,Due to the role of the internal filter capacitor of the inverter,Thus reducing reactive power loss,The active power of the grid is increased。

introduction:Circuit breakerGenerally by the contact system、Arc-extinguishing system、Operating mechanism、trip、Shell composition。 When short-circuited,Heavy current(normal10to12times)The generated magnetic field overcomes the reaction of the spring, Trip pull operation mechanism action,Instantaneous switch trip。When overloaded,Increase of current,Heat increase,The bimetal sheet deforms to a certain extent to push the mechanism action(Higher current,The shorter the action time)。 They have electronic ones now,Use the transformer to collect the current of each phase,Compare with the set value,The microprocessor sends a signal when the current is abnormal,Make the electronic trip drive the operation mechanism。

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,Because the rotor and stator of the three-phase asynchronous motor rotate the magnetic field in the same direction、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. When a conductor cuts a line of f
