离心风机轴承部的修理保养经常查看轴承润滑油供油情况，假如箱体呈现漏油，能够把端盖的螺栓拧紧一点，这样还不行的话，或许只好换用新的密封填料了。
During
the repair and maintenance of the bearing part of the centrifugal fan,
always check the oil supply condition of the bearing lubricating oil. If
the box shows oil leakage, tighten the bolts of the end cover a little.
If this is not enough, maybe we have to use new sealing packing.
（4）其他各配套设备的修理保养各配套设备包含电机、电动执行器、仪器、仪表等的修理保养详见各自的运用说明书。这些运用说明书都由各配套制造厂家提供，本制造厂将这些说明书随机装箱提供槽模具 一次性止血带 保定水处理设备 一次性止血带 保定空压机 北京真空泵给用户。

The repair and maintenance of other supporting equipment, including
motors, electric actuators, instruments, and meters, are detailed in
their respective operating manuals. These operating instructions are
provided by various supporting manufacturers, and our factory will
randomly box these instructions and provide them to users.
（5）.离心风机停止运用时的修理保养风机停止运用时，当环境温度低于5℃时，应将设备及管路的余水放掉，以避免冻坏设备及管路。

Repair and maintenance when the centrifugal fan is out of service When
the fan is out of service, when the ambient temperature is lower than 5
℃, the residual water of the equipment and pipeline should be discharged
to avoid freezing the equipment and pipeline.
（6）.风机长期停车寄存不用时的保养作业A、将轴承及其它首要的零部件的外表涂上防锈油以免锈蚀。B、风机转子每隔半月左右，应人工手动搬动转子旋转半圈（既180°），搬动前应在轴端作好符号，使本来上方的点，搬动转子后坐落较下方。

Maintenance work for long-term parking and storage of fans A. Apply
rust proof oil to the surface of bearings and other primary components
to prevent rusting. B. Every half month or so, the fan rotor should be
manually moved and rotated by half a turn (i.e. 180 °). Before moving, a
symbol should be placed on the shaft end to make the point originally
above sit lower after moving the rotor.
