The use of shaft diaspora hot fan and maintenance
Axis diaspora hot fan USES a wide range of general can be used in metallurgy, chemical industry, light industry, food, medicine and civil buildings and other places ventilated take a breath or enhance heat dissipation. If the casing, can also be used as free fan, can also be used in long exhaust pipe interval series installation, in order to improve the air pressure in the pipeline. The diaspora in shaft heat fan before use, in use, after use, we need to pay attention to what aspects, to make use of the cooling fan is better longer. Here is what these considerations.
scatter thermal fan debugging
1, the axial shaft diaspora hot fan resettlement has been completed, check the cooling fan rotation before initiating flexibility, if there is a sticky friction phenomenon blade with all hands. Check the cooling fan and the adjacent pipe for legacy things and other debris.
2, check the throttle pipe is fully open.
3, should be far away from the cooling fan.
4, start the cooling fan, check with blades to rotate logo tag, after inspection, commissioning 10 - 30 minutes to stop, look for loose phenomenon, blade vibration damping seat connected to the foundation bolt looseness or, after everything is ok, just officially launched, in operation.
shaft diaspora fan running check
shaft diaspora hot fan at run time, the main monitoring of the motor current, the current is not only the cooling load tag, and also some abnormal changes in the forecast. In addition, should often check the vibration of the motor and the cooling fan is normal, and presence of friction, abnormal noise. The parallel operation of the cooling fan should be paid attention to check whether the cooling fan running in surge condition. In normal operation, in case of the following environment should be the outage detection:
1, axis diaspora heat produce strong vibration or scratches;
2, motor current rise suddenly, and more than the rated current of the motor;
3, motor bearing temperature rise sharply.
shaft diaspora fan maintenance and storage
1, using the environment should always keep clean and tidy, cooling fan surface clean, inlet and outlet should not have the sundry, regularly remove the cooling fan and the pipe of dust and other sundry.
2, only in the cooling fan is completely under the normal operation, at the same time to ensure the power supply facilities sufficient capacity, voltage stability, it is strictly prohibited to open phase running, power supply line must be dedicated line, should not use temporary line power supply for a long time.
3, the cooling fan found in operation process, the cooling fan has a severe fever, abnormal sound, motor shell charged, the phenomenon such as switch trip, can't start, it is necessary to stop the machine immediately to check. In order to ensure safety, don't allow in the cooling fan operation for repair and maintenance should be done after commissioning for about five minutes, confirm no abnormal phenomenon to boot.
4, according to the using conditions from time to time to supplement or replace bearing grease ( Motor bearing, closed during the life period without replacing grease) , in order to ensure the cooling fan in the process of running a good lubrication, refueling times no less than 1000 hours/time closed bearings, bearing and motor oil with zl - 3 lithium base grease filling the 1/3 of bearing inner and outer ring, it is forbidden to short of oil.
5, the cooling fan should be stored in dry environment, avoid motor be affected with damp be affected with damp. When the cooling fan in open air, defensive measures. In the process of storage and handling should prevent the cooling fan knock against, so as not to damage the cooling fan.
