Working principle of double acting cylinder The switching action of the double acting cylinder is driven by the air source；Vent open，Vent close，Hold the air in place；Double acting cylinder A cylindrical metal part that guides the piston through a straight reciprocating motion 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。I believe that many people do not know the working principle of the double acting cylinder, in fact, it is similar to the working principle of the cylinder，The following Feng Ye Xiaobian will take you to see the picture to understand。
Linear moduleIt is a linear transmission device，There are two main ways。One is composed of ball screw and linear guide rail，The other is composed of synchronous belt and synchronous belt wheel。It has a wide range of use，Easy to install，High precision，It is accepted by the majority of users！It eliminates the need to create its own linear motion mechanism。 Linear module（ linear unite）It is a general term for devices that can achieve linear motion in the field of automation industry，Also known as positioning module。Linear modules can be considered as mechanical engineers through the transformation of machinery and mechanical development，Share experiences and exchange knowledge with each other，The result is a universally used intellectual product。
one、Precautions for use： 1. Do not touch the sliding seat during product operation and maintain a safe working range。 2. Ball screwWhen the product is used vertically【Zshaft】In order to prevent items from falling, it is recommended that the motor be equipped with a brake device；Gear belt drives are not recommended for vertical use【Zshaft】。 3. Resonance may occur when the effective stroke is too large，The greater the travel, the greater the speed should be reduced。 two、oiling： 1) Lubrication is essential when using linear module slides，If not fully lubricated，The friction resistance during operation will increase and may become the main reason for shortening the product life，The lubrication methods are roughly divided into manual lubrication and automatic forced lubrication，Depending on the operating speed of the system’Use the environment and other requirements to make appropriate choices 2) The frequency of lubricating oil feeding varies according to the conditions of use and the environment，General situati
By frequency converterThe operation of driving synchronous motor is accomplished by starting with excitation。 Working principle： Before the frequency converter outputs voltage to the stator of synchronous motor，Firstly, a certain exciting current is passed through the exciting device to the exciting winding of the synchronous motor，The inverter then outputs the appropriate voltage to the armature winding of the synchronous motor，Starting motor。 The Angle between the armature voltage vector of the synchronous motor and the magnetic pole position of the rotor must be within a certain range，If its not within that range，Synchronous motor may cause the system to be out of step。Before the motor starts，The Angle is arbitrary，So you have to control the Angle to this range，The motor can gradually enter a stable synchronous operation state。Through this phenomenon，We can determine that the biggest obstacle when the frequency converter is applied to the synchronous motor is the start synchronizing stage。
Servo motorAllows control of speed，The position accuracy is very accurate，The voltage signal can be converted into torque and speed to drive the control object。Servo motor rotor speed is controlled by input signal，And can react quickly，In the automatic control system，Used as an executive element，And has a small electromechanical time constant、High linearity、Starting voltage and other characteristics，The received electrical signal can be converted into angular displacement or angular speed output on the motor shaft。Divided into DC and AC servo motor two categories，Its main characteristics are，When the signal voltage is zero, there is no rotation，The speed decreases at a constant rate as the torque increases。 Working principle： 1、Servo system（servo mechanism）Is to make the objects position、orientation、An output controlled quantity such as state can follow an input target（Or value）The automatic control system of arbitrary changes。Servo mainly relies on pulse positioning，Basically you can think of it this way，Se
Optical fiber connector development With the continuous development of domestic telecommunications，Optical fiber communication has stepped into the practical stage，And the scope of application is more and more wide。Optical fiber connector，It is removable between optical fibers（Events）Connected device，It precisely joins the two ends of the optical fiber，So that the output light energy of the transmitting fiber can be coupled to the receiving fiber to the maximum extent，The influence on the system caused by its involvement in the optical link is minimized，This is the basic requirement of optical fiber connectors。The development process mainly includes the following2Point problem，The following Feng Ye Xiaobian will take you to understand。
Deep groove ball bearingSuitable for high speed or even very high speed operation，And very durable.，No frequent maintenance required。The friction coefficient of this kind of bearing is small，Limit speed height，Varied in size range and form，Application in precision instrumentation、Low noise motor、CARS、Motorcycle and general machinery industries，It is a kind of bearing widely used in the machinery industry。Mainly bear radial load，It can also withstand a certain amount of axial load。 Timken ball bearings are designed specifically for aviation applications to withstand radial forces、thrust、torque、Reverse thrust or combined load。We offer two basic Conrad constructs：HKandHD。In addition，Timken also offers two angular contact configurations：HAandHT。Bearings are available in single bearing unit form or in preload kit form。 Size range：10mmto600 mmOutside diameter
Variable frequency motorIt means under standard environmental conditions，In order to100%Rated load in10%~100%Continuous operation within the rated speed range，A motor whose temperature rise does not exceed the allowable value of the motors calibration。 With the rapid development of power electronic technology and new semiconductor devices ,Ac speed regulation technology has been continuously improved and improved ,Gradually improve the frequency converter with its good output waveform、The excellent performance/price ratio is widely used in AC machines。 Such as: A large electric motor used in rolling steel in a steel mill、Small roller table motor、Traction motors for railway and urban rail transit、Elevator motor、Lifting motor for container lifting equipment、Motors for pumps and fans、compressor、Electric motors for household appliances have successively used AC variable frequency speed regulating motors ,Good results have been obtained。The use of AC variable frequency speed regulating motor has obvious advan

The difference between solid state relays and ordinary relays There are two types of relays. One is an electromagnetic relay（General relay）Another is a solid-state relay，There are many different differences between the two，Below, Feng Yes Xiaobian will take you to understand the difference between solid state relays and ordinary relays： 1、Structural distinction：Electromagnetic relays work by the suction between the magnet core and the armature generated by the circuit in the input circuit；Solid state relays use electronic components to perform their functions without mechanical moving components，Inputs and outputs are isolated。
