There are several techniques to be noticed in the process of failure maintenance:
First, before the repair should be before and after careful observation and investigation of the failure of various phenomena, especially to the operator a detailed understanding of the failure process and background, the maintenance work is a complex project, in did not fully understand the fault, and accurate judgement of the fault qualitative, not rashly maintenance.
Second, before specific maintenance work, as a engaged in the use of veterinary ultrasound machine farms and technical personnel should first become familiar with the working principle of the machine and the specific circuit structure, so that
Helps to understand the failure of the nature of the failure to understand the performance of the various phenomena, thereby improving the quality of maintenance.
Third, before the specific maintenance, should also be familiar with the main function of B ultrasound instruments and the various functions related to the operation. In this way, it is helpful to compress the fault range and find the fault position of the instrument and shorten the maintenance time from the mutual relations between the various functions and various functions.
Fourth, the power part is one of the multiple parts of the ultrasonic fault, because the power consumption is large, the temperature is high, so the failure rate is high. The form of the power supply fault is also varied, which is often expressed as a part of the whole system or system. The instrument can not work properly because of the interference of the power supply part. In most cases, it should be the first to check the work of the power supply is normal or not.
Fifth, the remaining parts of the ultrasonic diagnosis system, such as the circuit in plate, due to the high degree of integration of the circuit, and most of them belong to a special device, usually only do board level maintenance, in the fault diagnosis process of the search should be based on the principle of circuit,
The instrument operator describes the fault background and the fault phenomenon, the instrument shows the fault code.
The understanding and investigation, as well as other aspects of a comprehensive judgment, in order to determine the fault location.
Sixth, B ultrasound diagnosis system in the peripheral part, namely the B-ultrasonic probe is often one of the parts of the fault, but the probe is relatively straightforward, not a complex structure and relatively independent, fault diagnosis is relatively easy, as long as in routine application process, collision avoidance, practical promptly clean treatment
