4-72离心风机可作为一般工厂及大型建筑物的室内通风换气用，输送空气和其它不自燃的，对人体无害的，对钢材无腐蚀性的气体，气体内不许有粘性物质所含尘土及硬质颗粒物不大于150mg/m3,气体温度不得超过80℃。
4-72 centrifugal fan can be used as the indoor ventilation of general factories and large buildings to convey air and other non spontaneous combustion, harmless to human body, non corrosive gas to steel. There shall be no dust and hard particles in the gas containing viscous substances not more than 150mg / m3, and the temperature of the gas shall not exceed 80 ℃.



1、离心通风机的 维护，必须在停机、断电及有人监护的 情况下进行。风机盘管无论是空调机组还是新风机组使用和安装都较为普遍，新风机组和空调机组有所区别，但可以功能互补。建议大家安装新风机组的同时，然后每个房间内再单独安装风机盘管，这样可以做到取长补短，同时还可以达到更加节能舒适的目的。
1. The maintenance of centrifugal fan must be carried out in case of shutdown, power failure and supervision. Fan coil unit is widely used and installed in both air conditioning unit and fresh air unit. Fresh air unit and air conditioning unit are different, but they can complement each other. It is suggested that when installing the fresh air unit, then install the fan coil unit separately in each room, so that we can learn from each other's strengths and make up for the shortcomings, and at the same time achieve the purpose of more energy-saving and comfortable.

2、离心通风机启动前应检查风机及管道内有无防碍转动的 物品，如有则应先清除后方可启动。
2. Before starting up the centrifugal fan, check whether there are any objects hindering the rotation in the fan and pipeline. If there are any, remove them before starting.

3、正式使用前必须进行试机，在确保接线正确，风机（Draught Fan）无异响，电机不超载，风机叶轮旋向与标识一致的 前提下方可正式使用。
3. Before formal use, the test machine must be carried out. It can be formally used on the premise that the wiring is correct, the draught fan has no abnormal noise, the motor is not overloaded, and the rotation direction of the fan impeller is consistent with the identification.
4、不要过于频繁（frequency)的 启动与停止风机（Draught Fan），否则很容易导致电机的 烧毁。
4. Do not start and stop the draught fan too frequently, otherwise it is easy to burn the motor.



5、不要让杂物堵住电机的 散热扇进风口和电机表面的 散热齿，防止因为电机散热不良而导致电机烧毁。风机盘管空调机组负荷空调区域的热湿负荷，对空调区域的空气起到综合处理的作用，同时保证一定的新风量。空调机组通常主要是控制空调区域的温度湿度和空气质量等，空气处理过程一般比较复杂。
5. Do not let the sundries block the air inlet of the cooling fan of the motor and the cooling teeth on the surface of the motor to prevent the motor from burning due to the poor cooling of the motor. The fan coil unit loads the heat and humidity load in the air-conditioning area, which plays a role in comprehensive treatment of the air in the air-conditioning area, while ensuring a certain amount of fresh air. Air conditioning units usually control the temperature, humidity and air quality in the air-conditioning area, and the air treatment process is generally complex.

6、应定期对风机的 各零部件(电机、叶轮（指装有动叶的轮盘）、轴座、机壳进风口等)进行检查，以保证风机能随时启动，正常运转。新风换气机新风机组一般来说不承担空调区域的热湿负荷，主要功能就是送新风。当然理想状态是送风的温度和湿度恒定了，所以新风机组一般控制送风温湿度。
6. The components of the fan (motor, impeller (wheel plate with moving blades), shaft seat, air inlet of the casing, etc.) shall be inspected regularly to ensure that the fan can start at any time and operate normally. Generally speaking, the fresh air unit of the fresh air ventilator does not bear the heat and humidity load of the air conditioning area, and its main function is to supply fresh air. Of course, the ideal state is that the temperature and humidity of the air supply are constant, so the fresh air unit generally controls the temperature and humidity of the air supply.



7、为避免叶轮因动平衡遭到破坏而引起振动加剧而导致风机损坏，须每月定期对叶轮进行检查，如发现叶轮表面有积尘或油渍污垢必须清理干净，风机才能继续使用。
7. In order to avoid the damage of the fan caused by the damage of the dynamic balance of the impeller, the impeller must be inspected regularly every month. If there is dust or oil dirt on the surface of the impeller, it must be cleaned up before the fan can continue to be used.

8、4-72型离心通风机长时间不使用而重新使用时，要检查各连接部件是否牢靠，并经试运行正常方可重新使用。
8. When the 4-72 type centrifugal ventilator is not used for a long time and is reused, it is necessary to check whether the connecting parts are firm, and it can be reused only after the normal trial operation.

9、若发现风机运转过程中有异响或震动加剧，必须立即停机检查，待排除故障后，方可重新投入使用。
9. If any abnormal noise or vibration is found during the operation of the fan, it must be stopped immediately for inspection, and it can be put into use again after troubleshooting.



10、带式传动系统在使用一段时间后，皮带会变得松软，需用户定期张紧皮带。
10. After the belt drive system is used for a period of time, the belt will become soft and the user needs to tension the belt regularly.

11、轴承座的 轴端密封件工作一段时间后效果会有所降低，此时应适当调整密封调节环压紧石棉。
11. After working for a period of time, the effect of the shaft end seal of the bearing seat will be reduced. At this time, the sealing adjusting ring should be adjusted properly to compress the asbestos.
