The cooling fan is widely used in today's society, and all walks of life are concerned with the problem of heat dissipation. Such as electronic products, mechanical equipment, lighting stage, industrial sewage, medical equipment and so on.
Many medical devices are equipped with cooling fans, such as high-frequency electric knife, biochemical apparatus, immune instrument, blood coagulation, blood analysis instrument and so on.
Common problems are:
First, noise
Noise problems are most common in the use of cooling fans. If the noise of the cooling fan is found to be too loud during the use of medical equipment, check the bolts to see if it is loose. Also check the cooling fan impeller is loose, most of the time a cooling fan noise are and blade are the links, so once the cooling fan noise, many users will be thinking of to check the cooling fan impeller part first.
The use of heat dissipation fan and heat dissipation fan in medical device is useful for the use of high frequency electric knife, biochemical apparatus, immune instrument, blood coagulation, and blood analysis instrument.
Second, the motor does not rotate.
If medical such phenomenon in a centrifugal fan, must cut off power supply first, then check, if charged check is likely to threaten the life safety of the maintenance staff, constitute a great safety hidden trouble. In fact, as long as the power supply problem is involved in many faults of the cooling fan, the power supply must be cut off to ensure safety.
Third, bearing vibration.
The vibration of the cooling fan can cause the failure of bearing and blade damage, bolt looseness, casing and duct damage, which seriously endangers the safe operation of the fan. There are many reasons for the vibration of the cooling fan bearing, such as the ability to take appropriate measures for the analysis of different phenomena, which can often result in half the effort.
Although the fault is similar to other industries, it depends on the situation. In addition, it is necessary to pay more attention to the daily inspection and maintenance of the cooling fan. The doctor is a very sacred profession, and the equipment in hand is very important.
