Gas sensors are mainly used to detect a specific gas，Measure whether the gas is present near the sensor，Or in the air near the sensor。therefore，In the security system，Gas sensors are often indispensable。These sensors can provide flammability for security systems、Information on flammable and toxic gases，And the oxygen consumption in the area，Carbon dioxide ratio。
smcWorking principle of solenoid valve Solenoid valves are industrial equipment controlled by electromagnetism，It is a basic element of automation used to control fluids，actuator，Not limited to hydraulics、pneumatic。SMCIt is an industrial control component commonly used in the automation industry. How much do you know about its working principle？The following Xiaobian will take you to understandsmcWorking principle of solenoid valve：
Relay working principle wiring diagram Relays are often used in the automation industry as industrial control components，The following Xiaobian will take you to understand its working principle and wiring diagram。 Working principle：
TIMKENCylindrical roller bearingsDesigned for high radial loads or even with eccentricity、Improper lubrication、There is impurity、Very high speed or very high stress environment。 Compared to other forms of roller bearings，Cylindrical bearings can carry high radial loads，There are three basic types，To meet various application requirements。 TIMKENSingle row cylindrical bearing： Single row cylindrical bearings with cages are available in six different designs，Various inner and outer ring configurations meet different application requirements。 TIMKENDouble row cylindrical bearings： Double row cylindrical bearings have higher radial load capacity than traditional single row bearings。 TIMKENFour row cylindrical bearings： Four row cylindrical bearings have extremely high radial load capacity，But no thrust load capacity。This type of bearing is mostly used in roll neck applications in the metal rolling industry。
Vector control time，The current is divided into excitation current and torque current，If only the excitation current is given and no torque current is given，Electric machineWill not change，But magnetic moment current is also AC current，Three phases in the motor can also form a rotating magnetic field，Why isnt the motor running，Very contradictory。 The excitation current and torque current are given under the synchronous coordinate system（synchronizationdqshaft）。Synchronous coordinate system= Rotor speed+Slip rate。If you dont torque，So the slip is zero。The rotating magnetic field rotates at the same speed as the rotor，No torque output。If the rotor doesnt turn，At this time, the rotating magnetic field generated in the motor is not non-rotating，Zero frequency。Once rotating the magnetic field and rotor different speeds，And that forms the slip rate，The rotor will have torque。merely，Now the torque current cant be zero。
Neumans cylinder installation diagram Newmans cylinders are made of cylinder barrels、End cover、piston、Piston rod and seal components, etc，A cylindrical metal part that guides the piston to move in a straight line in a cylinder。The following Xiaobian takes you to look at the Neumans cylinder installation diagram。
Omron programmable controller Omron programmable controller for shortPCorPLCIt is an electronic system for numerical operation，Specifically designed for use in industrial environments。It uses a memory that can be programmed，Used to store logical operations and sequence control during execution、timing、Instructions for counting and arithmetic operations，And through digital or analog input(I)Sum output(O)port，Control various types of machinery or production processes。
Our linear precision positioning slidesStepper motor or servo motor as the power source，High precision configurationACME、Ball screw or tooth synchronous belt、High rigidity aluminum alloy profile body and high speed and high precision double guide rail（Or four rails）Equal composition。With high rigidity，High precision，High speed，Economic and durable characteristics，Dust and fall-proof material，And small in size、Light weight，Large load capacity，Quick response，Assembly and replacement of motor and other components are simple and convenient，Easy to install。It is designed with two or four rails，The load capacity and anti-overturning moment of the sliding table are greatly improved，Extremely rigid。All guide rails are rolling friction，High speed，Good accuracy，High sensitivity，Long service life，Roller guide rail can be selected according to different requirements、Ball rectangular guide、Roller guide、Linear ball bearing guide or engineering plastic sliding sleeve guide。Special plain bearings are used，We can increase th
Wound rotor motorIn principle, it is equivalent to an ordinary asynchronous motor，There are structural differences，So there are distributed windings on the rotor。If the winding on the rotor is shorted at the collector ring，This motor（In usage）Its just an ordinary cage asynchronous motor。 The use of winding asynchronous motors，It is generally in some occasions that require large starting torque，Like a crane（crane）。Its principle is to change the resistance of the rotor winding，To change the slip rate of the asynchronous motor，To change the torque of the motor。Its stator is directly connected to the three-phase AC power supply，The rotor windings are generally connected in series to a variable resistor with a certain resistance value。When the motor starts，The resistance value of the variable resistor is a large value，After the boot is complete，By adjusting the resistance value，Finally, the resistance value is zero。
Parker cylinder size Parker cylinder is a cylindrical metal machine that guides the piston to move in a straight line in the cylinder。Air in the engine cylinder expands to convert thermal energy into mechanical energy；The gas in the compressor cylinder is compressed by the piston and the pressure is increased。The specifications selected for each device are also different，The following Xiaobian will take you to understand the Parker cylinder size chart。
