X-ray machine for precision instruments, by professionals with special equipment to repair. Repair first rule out intuitive faults (such as: short, touch line, key switch, fuse, etc.), do not take apart the host and switching power supply.
1, the machine system general fault detection methods:
1.1 digital display board on the X-ray tube voltage, current display, that is, that there are rays generated, if the fluorescent screen does not light up, the general image intensifier is faulty, need to be replaced.
1.2 digital display is bright, but no X-ray tube voltage and current display, this can be judged as the power supply is normal, the fault is in the main control board or doubler, need to return to the maintenance.
1.3 The whole machine after power on the front panel has a display, but can not work properly, the work indicator does not light up, you need to check: a, check the drive board plug is firm; b, the front panel plug is firm; c, drive tube plug is firm.
1.4 After the machine is energized, the over-temperature indicator light is always on, it is necessary to check: a. Check whether the temperature of the high-voltage ray source is too high, if not high, it is necessary to check whether the base of the high-voltage ray source is firmly plugged.
1.5 The whole machine does not work after power on, need to check: a, check whether the 24V power supply is normal; b, whether there is a display on the front panel, such as abnormal need to return to the factory for maintenance; c, check the DC/DC module, abnormal need to return to the factory for maintenance.
1.6 such as enhancers, multiplier bar bad need to return to the factory with the help of production equipment to repair.
2 image adjustment methods and steps:
The whole machine should be adjusted to the minimum position of the voltage and current before the start, and then after the start of the voltage and current according to the size of the object to be fluoroscopic, thin and thick to make the appropriate adjustments until the image is clear, the reference values are as follows:
2.1, for adult limb fluoroscopy, the general adjustment of the display panel knob: current 0.5mA, voltage 65-90KV;
2.2, for adult limb fluoroscopy general adjustments to display panel knob: current 0.5mA, voltage 65-90KV.
2.2, for children limb perspective general adjustment display panel knob: current 0.3-0.5mA, voltage 45-65KV.
2.3, for other objects, according to the actual situation to adjust.
