Abstract：Ultrasonic equipment is a kind of medical instrument with high precision and high spatial resolution, which will produce
various kinds of failures in the process of use. Through the analysis of the common faults of mindray DC-8 ultrasonic equipment,
the maintenance ideas were discussed and the methods were summarized in this paper. Firstly, three kinds of common faults
were introduced. The first fault was the power module fault. After the device was connected to the power, the machine could not be
powered on and the machine was abnormal; The second fault was the launch plate fault. After starting up, there was a secret channel
in the image display area, which affected the image quality and clinical diagnosis; The third fault was the image interference
phenomenon caused by peripheral equipment. Then through the fault situation and error phenomenon analysis, this paper established
a set of correct troubleshooting ideas. The method can effectively solve the fault problem, improve the use efficiency of equipment.
