1. First, it is clear whether the working conditions and peripheral environment of the gas-liquid turbocharging cylinder are normal. First, it is clear whether the mechanical part of the equipment or the electrical control part of the equipment, or the fault of the air liquid supercharger itself, and check the conditions of the pressurized cylinder of the gas liquid to meet the requirements of the normal operation.
2, regional judgment based on the fault phenomena and characteristics to determine the area related to the fault, gradually reduce the range of the fault, detection of the element in this area, analysis of the causes, and finally find out the specific location of the fault.
3. A comprehensive analysis of the types of malfunctions. In order to avoid blindness, in order to avoid blindness, a comprehensive analysis and logical judgment must be carried out according to the basic principle of the system to reduce the gradual approximation of the suspect and find out the fault location.
4, fault diagnosis is based on operation records and certain system parameters. It is the scientific basis for the establishment of system operation record, which is the scientific basis for the prevention, discovery and treatment of faults; the establishment of the breakdown analysis table of the equipment operation is a summary of the use of experience, which helps to make a quick judgment on the failure phenomenon, and has certain detection means to make accurate quantitative analysis of the fault.
5. When the cause of the possible failure is verified, it usually starts from the most likely cause of failure or the most easily tested place. This can reduce the load and increase the speed of diagnosis.
