WhenBlood
gas analyzer supply voltage suddenly increase and Figures in the
display disappear as well as printer problem during operation, what should we
do?
Failure a blood gas analyzer power supply voltage a sudden increase in the figures disappear on the screen. The investigation is slow melting fuse has blown. Put on the insurance to boot, sustained alarm, the display did not make the fault tips.
Maintenance: Remove all circuit boards, double-check whether the component color charred and cracked, and the measuring circuit with a multimeter and found that the exception is taken down to a single measurement. Check the Department of analog board breakdown, troubleshooting replacement.
Rush occasional moment of the power supply system, high pressure generated waves, caused by overload capacitor breakdown, because the local power energy crisis, power surge caused by line fault is more difficult to avoid. Prevention is the use of advanced power regulator device and install a regular and effective ground to minimize the harm.
Starting from the voltage increased: normal circumstances, current and voltage can be used sine wave, the anomalies current voltage change of the curve, there are two:
One is Qiufeng Bo, is characterized by a crest high and wide, contained in the energy;
The second is the sharp front wave is characterized by a crest high and narrow energy small. The first wave can be blocked by regulators or the insurance system will not cause failure; the latter wave voltage regulators and the insurance system does not recognize, resulting in the destructive effects of the first breakdown protection on the line capacitance, when re-boot then the blown fuse.
Failure two blood gas analyzers printer paper, unscrew the screws of the fixed printer with a multimeter measurement circuit and the motor part of the normal, turn the printer shaft, found gear loosening 2.carefully gear dial back test adjust the gears when the machine to the optimum position, with all-purpose adhesive fixed gear on the shaft, installed test machine can be dry.
Because the gear loose causing the printer paper, loose gear, two reasons:
One is the improper operating blood gas analyzer, such as forced tear or Wangchu pull the paper so that the gear shaft loose;
The second component of quality problems, gears and shafts with loose falling into gear prolapse, causing the printer paper. The use of a variety of imported medical equipment, printing a high failure rate, printer failures not only affect the normal work, and come at a cost to the user, it is operating properly is very important.
