一、风机使用中存在的问题

一木棋牌FENGJIZAISHIYONGGUOCHENGZHONGYOURUXIASIGEFANGMIANDEWENTI:

( 1 )风机选型不当。一是对所需要的风量与压力层层加码。出现这种现象有技术问题,有人为问题,也有现行设计规范和其它方面的问题。如一些非专业人员选择风机时缺少计算,缺乏调查分析,只靠手头已有的样本。有的设计主管人员保守求稳,计算风量、风压偏大,忽略经济性分析。更多的是管路系统设计安装质量差,维护管理水平低,难以考虑的因素多,这也给设计人员带来困难;二是风压选择过大或过小。风压选择过大将导致实际风量增大,会引起功率加大,耗能增加,初投资上升,尺寸及质量增加等一系列后果;风压选择过小会导致风量不足,不能满足生产需要。另外,电动机长期处于低负荷运转,效率低。

( 2 )风机不检测、无调节或调节不完善。很大一部分风机处于非满负荷工作,如果不进行适时必要的调节,就会造成风机、电动机低效运行,浪费能源。由于现场对风压、风量的需要不够明确,再加上缺少必要的调节,即使选择了高效风机也无济于事,即所谓高效风机低效运行。

( 3 )风机管网布置不合理。

( 4 )科学管理水平低。有相当数量的风机在现场处于无人管理或有名无实的管理状态中。有的风机长期处于不合理运行,某些现场人员只求可靠运行却不问节能与否。实际工艺生产不需要风机时,风机仍在恒速运行等等。

③按高效、节能及低噪的主次选型。通常,高效风机都称为节能风机,然而选用了高效并不等于就是节能。因为还要看实际运行的工况是否处在风机性能曲线的最高效率点附近,如果运行中工况是变化的,还要看实际工况是否全部或大部分落入风机性能曲线的高效区域中;就是同一台高效风机,若用两种不同的调节方式实现相同的目标,实际节能效果也可能差异很大。或者说,即使在同一高效风机系列中,为达到同一目标,可以存在两个或两个以上型号的风机,但在实际运行中节能效果亦大不相同,其中效率高者不一定就是节能最多的。因此,选风机时首先要确定主次。通常,对于功率大的风机要重视节能和高效,高效让位于节能;对于功率虽不大,但数量多的风机,选型时应注意高效风机;

④尽量减少沿程和局部阻力。为此,应力求使管网布置最简单,管线尽量短、管内流速低于经济流速,以减少沿程损失。另一方面,截面不宜突变。若必须扩大截面,则采取渐扩管。
