风机的维护保养
Maintenance and upkeep of fans
叶轮是风机的转动部件，其功能就是把气体通过风机运送到出气端。如，它由后盘，一个带有进口圈的直前盘和叶片组成。叶片为具有较大曲率半径的弧板叶片组成。在叶轮运转初期及所有定期检查的时候，只要一有机会，都必须检查叶轮是否可靠的固定在轴肩上，叶轮是否出现裂纹、磨损、积尘等缺陷。只要有可能，都必家庄电动伸缩门 保定桌椅 保定水处理设备 河北机械加工 保定养老院 保定防水须使叶轮保持清洁状态，并定期用钢丝刷刷去上面的 积灰和锈皮等。因为随着运行时间的加长，这些灰尘由于不可能均匀地附着在叶轮上，而造成叶轮平衡破坏，以致引起转子波动。
The impeller is a rotating component of a fan, whose function is to transport gas through the fan to the outlet end. For example, it consists of a rear disc, a straight front disc with an inlet ring, and blades. The blades are composed of curved plate blades with a larger curvature radius. At the initial stage of impeller operation and during all regular inspections, whenever there is an opportunity, it is necessary to check whether the impeller is reliably fixed on the shaft shoulder and whether there are defects such as cracks, wear, and dust accumulation on the impeller. Whenever possible, it is necessary to keep the impeller clean and regularly use a wire brush to remove any accumulated dust and rust on it. Because as the operating time increases, these dust cannot evenly adhere to the impeller, causing damage to the impeller balance and causing rotor fluctuations.
叶轮只要进行了修理，就需要对其进行再作动平衡。在作动平衡之前，必须检查所有紧定螺栓是否上紧。因为叶轮已经在不平衡状态下运行了一段时间，这些螺栓可能已经存在松动的可能。
Once the impeller is repaired, it needs to be dynamically balanced again. Before performing dynamic balancing, all fastening bolts must be checked for tightness. Because the impeller has been operating in an unbalanced state for a period of time, there may be a possibility of these bolts becoming loose.
