X-ray Camera Repair - the tube no voltage.

X-ray Camera Repair - the tube no voltage.

As a rule, the smaller the X-ray Camera, the more often it breaks. X-ray Cameras are very gentle in handling. She is do not like sudden changes in temperature. After each frame, the device should cool down. She fear overload.

X-ray cameras often fail with the power supply circuit and the x-ray tube. At what, failures happen, both in low-voltage and high-voltage circuits.

Repairing high voltage circuits at 40-60kV is difficult. They are in a sealed tube - a screen in which oil is poured for insulation and cooling. To get to them, you need to disassemble the entire apparatus.

Often, high-voltage capacitors in multipliers become unusable as well as failure of the film resistors.

Film resistors are single and combined, as in the photo. The wide strip, this is a 14 k? resistor, narrow, which is zigzagged, this is a 200 M? resistor. Just at 200M, it is beaten with high voltage, charred black dots, circled in oval.

Such a defect is eliminated by stripping the resistive layer from a part of the board and in the cleared corridor, SMD resistors in series of 10-50 M? are soldered in series. One row is enough. You can also solder other types of resistors, with a tolerance of 5-10 percent, as in the photo.

Some types of resistors are shown in the photo.

Large, of the glass, is a vacuum highly stable resistor brand KVM. KVM is Composite Vacuum Megaohmic. KVM resistors are designed to work in measuring circuits where increased accuracy is required.

The process of replacing the X-Ray tube is not difficult. Describe no need.

X-Ray Tubes should be searched in the manufacturers' catalogs. Chinese pipes are better not to take.

For example, many small-sized X-ray tubes are made by the American firm Oxford Instruments. These x-ray tubes are characterized by high flux density and good spot size stability.
