鐵路隧道式（shì）持續離心風機重點用於非法鐵路隧道建築通風換氣，能夠可用於鐵道鐵路（lù）隧道，山洞及非法工程和（hé）建（jiàn）築物物的建築通風換氣（qì），是其中一種超高壓力，低噪音，效率更高持續離心風機。鐵路隧（suì）道持續離心風機是其（qí）中一種較為額外的持續離心風機，重點（diǎn）用（yòng）在高速公路、鐵（tiě）道及地下鐵路等鐵路隧道的走向建築通風係統中（zhōng）。導致持續離心風機滾珠軸承持續過熱的原因有怎麽著（zhe）呢？
Tunnel centrifugal fan is mainly used for ventilation and ventilation in underground tunnels, railway tunnels, caves and underground engineering and buildings. It is a high pressure, low noise and high efficiency centrifugal fan. Tunnel centrifugal fan is a special centrifugal fan, which is mainly used in the longitudinal ventilation system of highway, railway and subway tunnels. What are the causes of overheating of centrifugal fan bearings?
1、持續離（lí）心風機主軸或主軸上的構件與滾（gǔn）珠軸承箱解放；
1. Friction between the parts of the spindle or spindle of the centrifugal fan and the bearing box;
2、發電機軸與風機軸有（yǒu）所區別心，使滾珠軸承箱內的內進行起伏滾珠軸（zhóu）承（chéng）持續別動；
2. The motor shaft is not concentric with the fan shaft, so that the inner rolling bearing in the bearing box does not move.
3、滾珠軸承箱體內進（jìn）行滑溜脂（zhī）過多；
3. Excessive grease in the bearing box;
4、滾珠軸（zhóu）承與滾珠軸承箱孔彼此之間有暇（xiá）時而適當，滾珠軸承箱的螺栓過（guò）緊或過鬆；
4. There is a gap between the bearing and the bore of the bearing box, and the bolt of the bearing box is too tight or loose.
