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。
What kinds of optical fiber connectors are there With the continuous rapid development of optical fiber connectors，More and more industries and different enterprises have used fiber optic connectors，There are also more and more enterprises in the fiber optic connector industry to develop and grow。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。To a certain extent，Optical fiber connectors affect the reliability and performance of optical transmission systems。
Linear slidePrecautions for use： 1. Do not touch the sliding seat during product operation and maintain a safe working range。 2. When the ball screw 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。
Back in the early 1990s，The concept of Maiudi double-sided synchronous belt has been gradually formed。At that time，Both by design ，The technical conditions are not enough to develop the conditions of double-sided teeth，However, some customers in special areas have proposed the idea of using such synchronization belts。in
SynchroflexThe specific cause of motor overheating caused by synchronous belt wheel
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。
This paper briefly introduces the influence of machining surface quality of bearing seat on fatigue strength。Damage to metal workpieces，It usually starts at the surface layer。Properties of mechanical workpieces，Especially its reliability and durability，To a great extent depends on the quality of the surface layer of the workpiece。Bearing housing is no exception，The machining surface quality of bearing seat was studied，It is to master the law of the influence of various technological factors on the quality of the machined surface in the machining process，And use these laws to control the processing process，Finally achieve the purpose of improving the surface quality of the workpiece and improving the performance of the product。
Solid-state relay420 v Solid-state relay，Is made of microelectronic circuits，Discrete electronic device，A contactless switch composed of power electronic power devices。The isolation device is used to realize the isolation between the control end and the load end。The input of a solid-state relay uses a tiny control signal，Achieves direct drive high current load。
nachiRadial ball bearing specification table nachiThe radial ball bearing is a universal design，Able to withstand loads of different sizes in high-speed motion。This type of rolling bearing is composed of a complete set of precision ball and cage and an inner and outer ring。The standard radial ball bearing has a deep groove structure,It can withstand radial loads and small axial loads from any upward direction.Radial ball bearings with large load capacity mainly bear radial loads。 Bearing size representation
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。
