怎样在试运行中保持离心风机电动机的效果

2018-08-19 22:00:08 常州亿创能源科技有限公司 阅读

离心风机的使用效果,需要每个组件的共同作用才能完成,只要一个组件出现了问题,那整个离心风机就可能会出现一些问题,对离心风机而言,如果一些问题能在调试中及时的发现,就可以避免很多其他的问题,尤其电动机的使用效果问题,怎样才能让电动机更好的作用于离心离心风机呢?为了能确保电动机的正常使用,我们需要在试运行的时候做好充分的保证,参与离心风机试运行的工作人员至少有两个人,这样可以让离心风机的一些突发状况得到及时的发现和良好的处理,而且也可以起到很好的预防效果,离心风机不会因为无人监测,出现问题造成严重的损失。

     启动电动机还需要注意选择恰当的启动方式,起动电机,如运转情况良好,则逐渐打开进风口调节风门,使离心风机逐渐达到正常的流量和全压,并密切关注电机电流,不得超过额定电流。试运转至规定时间(一般1小时),运行时轴承部位的均方根振动速度值不得大于6. 3mm/s.。用手或杠杆拨动转子,检查静动件之间是否有过紧或刮碰等现象,在没有这些情况下方可试转。关闭进出口调节风门或调节风阀(如合同中没有用户自备),因调节风门未关闭超电流烧毁电机的后果用户自负。对用水冷却轴承的离心风机,要检查冷却水管的供水情况是否良好,并在离心风机起动前向轴承座供应冷却水。严格检查机组的运行情况,发现有强烈的噪声或剧烈的振动,应立即停机检查原因,然后消除。

     如此一来,电动机可以得到很好的关注和保护,就可以防止一些因为电动机问题而发生的故障,在对离心风机的整体使用中,我们还要注意后期对电动机的保养和维护,只有这样才能让电动机持久的发挥良好的效果,并延长使用寿命。

The effect of centrifugal blower needs to be done by the common function of each component. As long as a component has problems, the whole centrifugal fan may have some problems. For centrifugal fan, if some problems can be found in time, it can avoid many other problems, especially electricity. How can the motor serve the centrifugal centrifugal fan better? In order to ensure the normal use of the motor, we need to make full guarantee in the trial operation. The staff involved in the centrifugal fan test run at least two people, so that some sudden conditions of the centrifugal fan can be found in time and good treatment, and it can also play a very good preventive effect. Centrifugal fans will not cause serious losses due to unmanned monitoring.

Starting motor also needs to pay attention to the selection of appropriate starting mode, starting motor, if the operation is good, then gradually open the inlet valve regulating the air inlet, so that the centrifugal fan gradually reach the normal flow and full pressure, and close attention to the motor current, not more than the rated current. The trial run to a specified time (usually 1 hours), and the mean square root vibration velocity of bearing parts should not exceed 6. 3mm/s. during operation. Use the lever or hand lever to move the rotor to check whether there is too tight or scraping and touching between the moving parts.  Shut down the inlet and outlet regulating valve or adjust the air valve (if there is no user in the contract), the user is conceited because the regulator does not shut down the overcurrent to destroy the motor. For centrifugal fans with water cooled bearings, check whether the water supply condition of the cooling water pipe is good, and provide cooling water to the bearing block before the centrifugal fan starts. Check the operation of the unit strictly and find that there is strong noise or severe vibration. Stop the machine and check the cause immediately, then eliminate it.

As a result, the motor can get very good attention and protection, can prevent some problems due to motor problems, in the overall use of centrifugal fans, we should pay attention to the maintenance and maintenance of the motor in the later period, only in this way, the motor will have a long time to play a good effect and extend the effect. Use life.
