排烟罩是常用的排烟通风设备，风机设备在使用一段时间后会产生很多问题，发生一系列故障。客户对于排烟罩的故障很是困惑。现在厂家根据多年的设计和生产经验，总结了如下排烟罩常见机械故障：
Smoke exhaust hood is a commonly used smoke exhaust and ventilation equipment. After using the fan equipment for a period of time, many problems and a series of faults will occur. The customer is very confused about the failure of the smoke exhaust hood. Now, based on years of design and production experience, the manufacturer has summarized the following common mechanical faults of smoke exhaust hood:
1、轴承温升过高：
1. Bearing temperature rise too high:
①轴承支架座剧列振动；②润滑油脂质量不好，变质，含有灰尘粘砂污垢等杂质，轴承座联接螺栓的紧力过大或过小，轴承缺油运行；③轴与轴承安装歪斜，前后二轴轴承不同心；④轴承损坏或轴承寿命已到；⑤排烟罩轴与电机轴平衡，皮带槽错位。
① The bearing support seat vibrates in series; ② The lubricating grease is of poor quality, deteriorated, contains impurities such as dust, sand, dirt, etc., the tightening force of the connecting bolt of the bearing seat is too large or too small, and the bearing runs in lack of oil; ③ The shaft and bearing are installed askew, and the front and rear shaft bearings are not concentric; ④ The bearing is damaged or its service life has expired; ⑤ The smoke exhaust hood shaft is balanced with the motor shaft, and the belt groove is misaligned.
2、风机振动：
2. Fan vibration:
①叶轮不平衡；②叶轮螺钉松动或轮盘、叶片变形；③基础的刚度不够或不牢固；④机壳与支架轴承与支架联接螺栓松动；⑤减振器位置不当引起偏移。
① Impeller is unbalanced; ② The impeller screw is loose or the disc and blade are deformed; ③ The rigidity of the foundation is not enough or firm; ④ The connecting bolts of the housing and support bearings and supports are loose; ⑤ The center of gravity shift is caused by the improper position of the shock absorber.
3、叶轮擦亮：
3. Impeller polishing:
①叶轮不平衡或变形；②机壳或进风口与叶轮摩擦；③叶轮反转引起叶轮紧固件松动；④叶轮轴盘孔与轴松动；⑤排烟罩进出气管道安装不良。
① Impeller is unbalanced or deformed; ② The casing or air inlet rubs with the impeller; ③ Impeller rotation causes impeller fasteners to loosen; ④ The impeller shaft disc hole and shaft are loose; ⑤ The inlet and outlet pipes of smoke exhaust hood are poorly installed.
4、启动时排烟罩处有响声：
4. There is noise at the smoke exhaust hood during startup:
风轮震荡太厉害。
The wind wheel vibrates too much.
隔热板震动。
The heat shield vibrates.
电机支架脚松动导致电机震动有响声。
The loose feet of the motor support lead to the vibration and noise of the motor.
机轴上的散热风叶震荡有响声。
The cooling fan blades on the shaft vibrate and make noise.
电机转轴有响声。
The motor shaft makes a noise.
紧固风轮上的螺母，如仍不行，请更换风轮。
Tighten the nut on the wind wheel. If it still fails, replace the wind wheel.
紧固隔热板的螺丝。
Tighten the screws of the heat shield.
紧固电机支架脚螺丝。
Tighten the motor bracket foot screws.
重新调整各中片的角度及位置。
Readjust the angle and position of each middle piece.
Jinan smoke exhaust hood manufacturer suggests that the motor can be replaced at this time.
