离心风机是目前工业生产中使用非常广的通风排气设备之一,依靠输入的机械能,提高气体压力并排送气体的机械,它是一种从动的流体机械。但是受知识的影响,很多企业主往往一安装上之后,就不再理会。其实离心风机不同状态下,所能取得的效果也不相同。本文主要分享了离心风机日常操作及维护措施,以下几点给予说明:

Centrifugal fan is one of the ventilation and exhaust equipment widely used in industrial production. It is a driven fluid machinery that depends on the input mechanical energy to increase the gas pressure and discharge the gas. However, affected by knowledge, many business owners often ignore it as soon as it is installed. In fact, the effect of centrifugal fan is different under different states. This paper mainly shares the daily operation and maintenance measures of centrifugal fan, which are explained as follows:

1、风机允许全压起动或降压电动,但应注意,全压起动时的电流约为5-7倍的额定电流,降压起动转矩与电压平方成正比,当电网容量不足时,应采用降压起动。

  1. Full voltage starting or step-down electric fan is allowed, but it should be noted that the current during full voltage starting is about 5-7 times of the rated current, and the step-down starting torque is directly proportional to the square of voltage. When the power grid capacity is insufficient, step-down starting shall be adopted.

2、离心风机在试车时,应认真阅读产品说明书,检查接线方法是否同接线图相符;应认真检查供给风机电源的工作电压是不是符合要求,电源是否缺相或同相位,所配电器元件的容量是否符合要求。

2. During the commissioning of centrifugal fan, carefully read the product manual and check whether the wiring method is consistent with the wiring diagram; Carefully check whether the working voltage of the power supply to the fan meets the requirements, whether the power supply is out of phase or in the same phase, and whether the capacity of the electrical components meets the requirements.

3、试车时人数不少于两人,一人控制电源,一人观察风机运转情况,发现异常现象立即停机检查;首先检查旋转方向是否正确;风机开始运转后,应立 即检查各相运转电流是否平衡、电流是否超过额定电流;若有不正常现象,应停机检查。运转五分钟后,停机检查风机是否有异常现象,确认无异常现象再开机运 转。

3. During commissioning, the number of people shall not be less than two, one shall control the power supply and one shall observe the operation of the fan. In case of any abnormality, stop the machine for inspection immediately; First, check whether the rotation direction is correct; After the fan starts to operate, immediately check whether the operating current of each phase is balanced and whether the current exceeds the rated current; In case of abnormality, stop the machine for inspection. After five minutes of operation, shut down the fan to check whether there is any abnormality, and then start it for operation after confirming that there is no abnormality.

4、双速风机试车时,应先起动低速,检查旋转方向是否正确;起动高速时待风机静止后再启动,以防高速反向旋转,引起开关跳闸及电机受损。

4. During the commissioning of two speed fan, start the low speed fan first to check whether the rotation direction is correct; When starting the high-speed fan, start it after the fan is stationary to prevent the high-speed reverse rotation from causing switch tripping and motor damage.

5、风机达到正常转速时,应测量风机输入电流是否正常,离心风机的运行电流不能超过其额定电流。若运行电流超过其额定电流,应检查供给的电压是否正常。

5. When the fan reaches the normal speed, measure whether the input current of the fan is normal, and the operating current of the centrifugal fan shall not exceed its rated current. If the operating current exceeds its rated current, check whether the supplied voltage is normal.

风机所需电机功率是指在一定工况下,对离心风机和风机箱,进风口全开时所需功率较大。若进风口全开进行运转,则电机有损坏的危险。风机试车时将风机进口或出口管道上的阀门关闭更好,运转后将阀门渐渐开启,达到所需工况为止,并注意风机的运转电流是否超过额定电流。

The motor power required by the fan refers to the large power required for the centrifugal fan and fan case when the air inlet is fully open under certain working conditions. If the air inlet is fully open for operation, the motor is in danger of damage. During fan commissioning, it is better to close the valve on the inlet or outlet pipe of the fan. After operation, gradually open the valve until it reaches the required working condition, and pay attention to whether the operating current of the fan exceeds the rated current.
