隧道式离心风机主要用于地下隧道通风换气,亦可用于铁路隧道,山洞及地下工程和建筑物的通风换气,是一种高压力,低噪声,高效离心风机。隧道离心风机是一种特殊的离心风机,主要用在公路、铁路及地铁等隧道的纵向通风系统中。造成离心风机轴承过热的原因有哪些呢?

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、离心风机主轴或主轴上的部件与轴承箱摩擦;

1. Friction between the parts of the spindle or spindle of the centrifugal fan and the bearing box;

2、电机轴与风机轴不同心,使轴承箱内的内滚动轴承别动;

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、轴承箱体内润滑脂过多;

3. Excessive grease in the bearing box;

4、轴承与轴承箱孔之间有间隙而松动,轴承箱的螺栓过紧或过松;

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.
