relay（English name：relay）。It is an electrical control element，Is when the input quantity（Excitation quantity）When the changes meet the specified requirements，An appliance that causes a predetermined step change in a controlled quantity in an electrical output circuit。It has a control system（Also known as input loop）And the controlled system（Also known as output loop）The interaction between。It is usually used in automatic control circuits，It actually uses a small current to control the operation of a large current“Automatic switch”。Therefore, it plays an automatic regulation in the circuit、Security protection、Conversion circuit, etc。
TIMKENCylindrical roller bearingsIts a bearing，It is characterized by large radial bearing capacity，The application is large and medium-sized motor、Rolling stock 。 Bearing classification： TIMKENCylindrical roller bearings are designed 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。 1.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。 2.TIMKENDouble row cylindrical bearings： Double row cylindrical bearings have higher radial load capacity than traditional single row bearings。 3.TIMKENFour row cylindrical bearings： Four row cylindrical bearings have extremely high radial load capacity，But no thrust
There are many possible cases of abnormal motor noise。electrically：Electric machinePhase loss，Rotor broken bar，Rotor sweeping。Mechanical aspect：Bearing oil shortage，End cap wear，Wind blade mill cover。Today, lets briefly analyze the reasons for the abnormal sound of the bicycle motor and the elimination methods！ 1、Fault cause： ①The motor internal bearing clearance is large。 ②Motor rotor bore sweeping。 ③Magnetic steel loosening、Fall off。 ④Internal axial movement of motor。 ⑤Brush motor commutator surface oxidation、ablation、Oil contamination、uneven、The commutator is loose。 ⑥The brush holder is loose、The brush holder is not right。
Industrial connector picture Industrial connectors are specifically designed to build a robust Ethernet connection in harsh environments，Tougher than previous connectors、stronger、More resilient。This new interface is widely believed to be“Industrial connector”，Its applications are not limited to manufacturing。The connectors are designed to withstand harsh industrial environments。The following Xiaobian will take you to see the industrial connector picture。
Linear module is a linear transmission device，There are two main ways。One is ball screwAnd 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。
Whats the Norman root like Root mother，It is a connecting pipe，Used for locking through wire connectors or other pipe fittings。Other names：Lock nut、Lock nut、A surname。The following Xiaobian will take you to see what the Norman building root mother is like。
Norman Tower root mother picture complete The Norman frame is designed to provide adjustment capability for spindle and other rotating machinery elements、Preload and fixed bearing。These nuts precisely set the bearings preload，It can withstand axial loads very firmly without loosening。Because the inner thread face of the nut is completely fitted to the male thread，These nuts can bear very high loads。Below, Feng Yes small edition will take you to browse the Norman floor root mother picture！
Xiaobian did not find the relevant knowledge about this series of products for a long time，Here to give you the popularization of inverter motor knowledge！ Asynchronous motorWhen the slip rate does not change much，Speed is proportional to frequency，It can be seen that changing the frequency of the power supply can change the speed of the asynchronous motor。In frequency control，Always want the main flux to remain constant。If the main magnetic flux is greater than the normal operating magnetic flux，The magnetic circuit is supersaturated and the excitation current increases，Power factor reduction；If the main magnetic flux is less than the normal operating magnetic flux，The motor torque decreases。 Working principle： Standardized motor test stands by test power supply、Electrical parameter test system、Test measurement and control system、Motor test and control report software, etc。 The test bench is driven by two test power sources respectively，One runs as an electric motor，One runs as a generator；Stati
pilzSafety relay specification PILZA safety relay is a combination of several relays and circuits，In order to complement each others abnormal defects，Complete function of relay with correct and low error operation，The lower the error and failure value，The following Xiaobian will take you to understandpilzSafety relay specification。
Working principle of safety relay A safety relay is a combination of several relays and circuits，In order to complement each others abnormal defects，Complete function of relay with correct and low error operation，The lower the error and failure value，The higher the safety factor，Therefore, it is necessary to design a variety of safety relays to protect different grades of machinery，The main objective is to protect machine operators who are exposed to different levels of risk。
