Knowledge points that automation equipment maintenance personnel should master

　　With the development of science and technology, the equipment used in all walks of life is becoming more and more advanced, and tends to be automated and intelligent. When people enjoy the convenience brought by automation equipment and intelligent equipment, it adds a lot of difficulty to the maintenance personnel of automation and intelligent equipment. If the equipment maintenance personnel do not keep pace with the times and fail to learn new technologies and knowledge in time There will be many difficulties when maintaining equipment. As an automation equipment and intelligent equipment maintainer, you need to learn and master those knowledge.

　　1. Electrical components and electronic components

　　Electrical components are an important part of automation equipment and intelligent equipment. To repair malfunctioning automation equipment, you must first be able to identify various electrical components and electronic components used in automation equipment, including:

　　Electrical components include: various types of button switches, limit switches, various types of relays, various types of contactors, various types of motors, frequency converters, touch screens, PLCs, servo drives, circuit boards, various types of sensors, etc.

　　Electronic components include: resistors, capacitors, inductors, transformers, diodes, triodes, field effect transistors, thyristors, integrated circuits, micro relays, solid state relays, etc.

　　2. Instruments

　　After we have mastered all kinds of electrical components and electronic components used in automation equipment and intelligent equipment, we will also use instrumentation to detect and judge the quality of various electrical and electronic components, and we can use instrumentation to check and judge automation equipment and intelligent equipment. Whether the working state of the circuit in the chemical equipment is normal, the instruments and meters that need to be used are: pointer multimeter, digital multimeter, clamp meter, capacitance meter, megohmmeter, thermal imager, oscilloscope, signal generator, programmer, integrated circuit test Instruments and other instruments.

　　3. Tool usage class

　　When repairing automation equipment and intelligent equipment, it is necessary to use some necessary maintenance tools, so that we can carry out the maintenance work smoothly, so that the equipment maintenance work can achieve twice the result with half the effort, and skillfully use the following tools: electric soldering iron, hot air table, micrometer, caliper, Feeler gauge, level, electric pen, wrench, screwdriver, vise, hacksaw, hoist, hand drill, impact drill, bench drill, grinder, cutting machine, electric welding machine, etc.

　　4. Circuit class

　　In the maintenance of automation equipment and intelligent equipment, first of all, we must be able to detect and determine whether the cause of the failure is caused by the mechanical part or the electrical part. Many maintenance personnel in this part of the circuit feel a little complicated, and even feel that they have no way to start. In terms of electrical circuits and electronic circuits, they should focus on mastering the following knowledge points: basic knowledge of electrical circuits and electronic circuits, methods of reading electrical schematic diagrams, reading engineering, The method of mechanical drawing, motor jog, forward rotation, forward and reverse rotation control circuit, single chip hardware circuit, motor star-delta control circuit, inverter operation control circuit, touch screen, PLC, inverter combined control circuit, etc.

　　5. Software

　　In automation equipment and intelligent equipment, many equipments use touch screen, PLC, inverter, servo driver, circuit board and other components, and software parts are used in these components. If you want to become a top automation equipment, intelligent If you are a master of chemical equipment maintenance, it is necessary to master some software usage methods. Mastering the usage methods of the following software will be of great help to your maintenance work: the use of Siemens PLC programming software, the use of Mitsubishi PLC programming software, the use of AB -Use of PLC programming software, use of Delta PLC programming software, use of touch screen configuration software, use of Siemens, Schneider, Yaskawa, Danfoss, ABB and other brands of inverter parameter setting software, use of CAD drawing software, electronic drawing software The use of Altium Designer software, the use of microcontroller programming software, etc.

　　6. Machinery

　　Knowledge points to be mastered in mechanical aspects of automation equipment and intelligent equipment, adjustment methods of chain drive and belt drive, disassembly and installation of bearings in mechanical equipment, adjustment method of clearance fit of various components of mechanical equipment, precautions for installation and maintenance of mechanical equipment , Disassembly and assembly precautions of mechanical equipment parts, etc.

　　7. Troubleshooting

　　When automation equipment and intelligent equipment fail, if maintenance personnel want to quickly and quickly find out the cause of the failure, they must understand the failure mechanism, failure characteristics, failure judgment methods, maintenance ideas, and maintenance steps of automation equipment and intelligent equipment. Etc., the mechanism of equipment failure, the phenomenon and characteristics of common equipment mechanical failure, the phenomenon and characteristics of common equipment electrical failure, the method of judging the fault location of equipment failure, the ideas and specific steps of equipment electrical failure maintenance, etc.

　　The above content is some knowledge points that Guangdong Shenzhen Guanshentai Technology Automation needs to master for an automation equipment and intelligent equipment maintenance engineer. If friends can master the above knowledge points, when the equipment under our jurisdiction fails, it will not be repaired. More difficult.
