In order to avoid human fault caused by improper maintenance and prevent natural faults and accidents in various aspects of centrifugal fan and motor, so as to give full play to the performance of the equipment and prolong the service life of the equipment, it is necessary to strengthen the maintenance of the centrifugal fan.
Centrifugal fan maintenance personnel must pay attention to the following points:
1, only under the condition that the centrifugal fan equipment is completely normal.
2, if centrifugal fan equipment starts after maintenance, attention should be paid to whether the parts of the centrifugal fan are normal.
3. Regularly remove impurities, dirt and water from centrifugal fans and gas pipelines, and prevent rust.
4. Repair of centrifugal fan equipment is not allowed in operation.
The following points for attention in the normal operation of centrifugal fans are as follows:
1, if the flow is too large, does not meet the requirements of use, or need less traffic in a short time, the throttle device can be adjusted.
2. Periodically check the sensitivity of the thermometer and oil standard, and control the oil level of the bearing box within the prescribed allowable range.
3. During the start-up, shutdown or operation of centrifugal fans, any abnormal phenomena should be checked immediately.
4. To check and find out the small faults, we should find out the reasons in time, try to eliminate or deal with it, such as the small fault can not be eliminated, or when a big fault is found, it should be checked immediately.
5, in addition to each demolition, should be replaced with lubricating oil, should also be replaced regularly.
6, E type transmission bearing block should be checked regularly (Ji Du), cleaning and adding lubricating oil to prevent bearing burn out.
