margin-bottom: 5px;"> <span style="font-size: 16px;">离心鼓风机其进风口上的整流筒,主要是起到引导和整流这两个作用的。如果,在风机上没有这一部件的话,那么,是会影响到气流实际流通面积的,以及风机实际流量的。所以,才需要有这一部件,以便来提升风机压力和保证流量。不过,这一离心风机的附件,在小型风机上,有可能是没有的。离心式风机是可以全压或降压启动的。不过,是有一些注意事项的,当离心风机全压启动时,启动电流应为5?倍的额定电流;当其降压启动时,降压启动转矩与电压平方之间,应是为正比关系?/span></p> <h2 style="text-indent: 2em;
