Fault diagnosis technology of hot-press based on case reasoning

Through adjustment, the processing procedures of entering, rising, heating, vacuum, film pressure, film stripping and falling can be completed automatically. It is mainly powered by oil pressure and compressed air, so it is necessary to have enough air pressure and air volume. The frame is made of steel plates, and the overall structure is reasonable. The two worktables can be recycled or used separately. The vacuum hot press manufacturer is a kind of electrical and mechanical connection equipment that heats two parts coated with flux in advance to a temperature sufficient to melt and flow the solder, and forms a * * * between the parts and the solder after curing. The heating rate can be selected according to different products. The titanium alloy indenter of Guangzhou hot press ensures the average temperature, rapid temperature rise and long service life. The pressure head is specially designed to be horizontally adjustable to ensure the average pressure of the components. Temperature numerical control, clear and precise. Equipped with digital pressure gauge, the pressure range can be preset. When there are some faults in the hydraulic control system management, input the equipment fault handling information through a personal computer interface. The system needs to form a fault case keyword according to the provided faults and the information society, and then use the search case library to retrieve whether there can be the same or similar cases with the fault cases to be diagnosed. If a perfectly matched case is retrieved, it will directly affect the generation of different fault diagnosis conclusions. When the diagnosis conclusion is not satisfactory, we need to match the similar cases in the case base according to the initial failure symptoms according to the environmental conditions of the learning task , continue to search, and then calculate the similarity between the case to be diagnosed and the target case, select the most similar case company according to the size of the similarity for comparative analysis and verification, and make corresponding policy adjustments to the case base according to the final results of the students. If no similar cases can be retrieved, the cause of the failure shall be found according to the actual use, → new cases shall be generated and stored in the case database. (2) System service function
The fault diagnosis expert system can simulate the fault diagnosis of marine hydraulic system by artificial experts. Its diagnosis process includes obtaining basic fault information and fault symptoms, inferring fault causes, drawing fault conclusions and putting forward fault management schemes. It has the functions of fault diagnosis, fault handling, fault analysis, education and training. ① Fault diagnosis and fault diagnosis is to find the target case base according to the fault information and case reasoning mechanism of the hydraulic system, and finally find the fault source through analysis, elimination and verification.
