If the high voltage generator fails, what measures shall we take to repair it?

The main component of the X-ray machine medical imaging system is the high voltage generator. When it fails, how can we eliminate it?

1 intuitive method is also known as the feeling method, that is, the use of human senses to see, hear, smell, touch and other means to determine the fault, which is similar to the Chinese traditional medicine.This method is suitable for the inspection of surface faults, such as whether the X-ray tube filament ignites, whether there is a spark or discharge in the circuit, and whether the components and connection wires are damaged or fall off.Listen for abnormal sound in the system, normal start and operation of rotating anode, abnormal high-frequency generator or ball tube, etc.Smell the smell of burning when the paste;After the power is cut off, touch some components, such as resistors, pressors, X-ray tubes by hand, and their temperature rise can be used to determine whether the circuit is normal or not.The fact shows that most of the faults can be determined by intuitionistic method and general knowledge.

2. Short connection Method When it is concluded that some control circuit should be on, but it is not on, a certain section of the circuit or some control contacts can be shorted with wires. Use this as a reference to determine the fault.This method is simple and easy, only one clamp line is needed, the fault can be detected by the method of point-by-point short circuit.

The high pressure generator is also a part of the film making machine. The 500mA medical diagnostic film machine displayed by Sinovel Imaging Equipment Co., Ltd. can be mainly used for medical units to perform photographic examination of human chest, limbs, pelvis and lumbar spine.
It has the following five advantages:
(1) Microcomputer control: liquid crystal display, easy to operate.
(2) New design of high frequency and high voltage generator: [Stable and accurate exposure conditions, lower radiation dose and reduce the production of soft rays, effectively protect patients and doctors.]
(3) Simple and convenient position display: [According to the selection of patient body shape and position, the exposure parameters are automatically set, and can be saved and modified.]
(4) New bed design: [Accurate rotation Angle, multi-angle photography, to meet the clinical needs.]
(5) Reassuring safety function: [Fault self-diagnosis function can quickly and accurately judge the fault status, and can automatically protect, display the fault code, accurate, convenient and timely.]
