1.离心风机拆卸前，除准备拆卸工具和材料外，对于输送气体或其他有害气体的风扇，须严密关闭进出水管的闸门，必要时应堵住盲板。如果入口和出口都是向下的，可以将水倒入下管中以进行水密阳雕刻 手套生产设备 果树反光膜 北京纯水设备 保定网站制作 排水槽模具封。要填充的水位高度应确保管道中的有害气体不会泄漏到工作场所。
1.
Before the disassembly of centrifugal fan, in addition to the
preparation of disassembly tools and materials, the gate of the inlet
and outlet pipes must be closed tightly for the fan conveying gas or
other harmful gases, and the blind plate should be blocked if necessary.
If the inlet and outlet are both downward, water can be poured into the
lower pipe for water sealing. The height of the water level to be
filled should ensure that harmful gases in the pipeline do not leak into
the workplace.
2.当拆卸润滑油离心风机的压力时，首先在冷却前释放并过滤润滑油，然后断开连接油管和阀体的法兰。
2.
When removing the pressure of the lubricating oil centrifugal fan,
first release and filter the lubricating oil before cooling, and then
disconnect the flange connecting the oil pipe and the valve body.
3.抬起上壳体或转子时保持水平位置，以免损坏机器部件。不应拆卸离心风机外壳的纵向接头。如果发送热气体的铸铁外壳被冷却，则须在外壳内部冷却后提升上壳体。
3.
When lifting the upper casing or rotor, maintain a horizontal position
to avoid damaging machine components. The longitudinal joint of
centrifugal fan housing shall not be removed. If the cast iron casing
that sends hot gas is cooled, the upper casing must be lifted after
cooling inside the casing.
4.在拆下滑动轴承之前，应测量衬套间隙和推力表面间隙。在移除密封之前应测量密封间隙。
Before
removing the sliding bearing, the clearance between the bushing and the
thrust surface should be measured. Before removing the seal, the seal
clearance should be measured.
5.拆卸时，检查拆下的部件是否有印痕。对于某些需要在不打印的情况下进行打印的零件，您须进行打印，以便更容易组装时尚修复位置。需要打印的部件包括不允许错位或定向的部件，以及影响平衡的部件，例如钥匙，盖子，衬套及其支撑环，联轴器及其销，离心式风扇的进气口，轴向流动通过可拆卸的离心风机叶片。
5.
When disassembling, check for any imprints on the removed components.
For some parts that need to be printed without printing, you need to
print them to make it easier to assemble and repair the position. The
parts to be printed include parts that are not allowed to be misplaced
or oriented, and parts that affect balance, such as keys, covers,
bushings and their support rings, couplings and their pins, air inlets
of centrifugal fans, and axial flow through removable centrifugal fan
blades.
