英國(guó)工業(yè)革命使人們的生活發(fā)生了翻天覆地的變化，蒸汽機(jī)的發(fā)明和應(yīng)用讓制造業(yè)和冶金行業(yè)飛速發(fā)展起來(lái)。風(fēng)機(jī)也是這些行業(yè)中*的重要設(shè)備。多年來(lái)技術(shù)人員對(duì)于風(fēng)機(jī)進(jìn)行了各種改進(jìn)更新，其目的就是要實(shí)現(xiàn)風(fēng)機(jī)使用環(huán)保，降低噪音，降低能耗的目標(biāo)。企業(yè)在挑選風(fēng)機(jī)時(shí)的側(cè)重點(diǎn)也正是技術(shù)人員要實(shí)現(xiàn)的這幾個(gè)目標(biāo)。所以在選購(gòu)風(fēng)機(jī)的時(shí)候，首先鎖定的方向就是環(huán)保機(jī)型，例如</span><strong style="font-family: "PingFang SC", Helvetica, "Microsoft YaHei", Arial, sans-serif; font-size: 16px;"><span style="color: rgb(0, 0, 0);">高壓風(fēng)機(jī)</span></strong><span style="font-family: "PingFang SC", Helvetica, "Microsoft YaHei", Arial, sans-serif; font-size: 16px; color: rgb(0, 0, 0);">。選擇機(jī)型后，就是要在操作方面多加注意，來(lái)盡量提高風(fēng)機(jī)的使用效率和使用年限。 <br /> 在本文中，我們主要來(lái)了解一下風(fēng)機(jī)在消除噪聲方面的有利措施。<br /> *，降低葉片進(jìn)口處氣流的相對(duì)加速度系數(shù)，降低風(fēng)機(jī)渦流噪聲。第二，采用合理的葉輪出口與蝸舌之間的幾何尺寸，合理的蝸舌形狀，使葉輪出口氣流與蝸舌作用的交變力及由于物面上渦旋脫落產(chǎn)生的交變力引起的氣流密度的變化減少，降低風(fēng)機(jī)的噪聲。第三，調(diào)節(jié)門(mén)配套設(shè)計(jì)時(shí)，采用合理的導(dǎo)葉數(shù)，使葉輪與進(jìn)口調(diào)節(jié)懛　共頻降低。第四，送風(fēng)機(jī)加消聲器。第五，風(fēng)機(jī)外殼加隔音包裹。<br /> 另外風(fēng)機(jī)安裝使用的過(guò)程中也有很多操作可以降低噪音。運(yùn)行中的高壓風(fēng)機(jī)，該設(shè)備馬達(dá)電流與真空度和壓力指數(shù)成正比，過(guò)高的電流會(huì)直接致使接觸器跳脫。在不發(fā)生跳脫的情況下，使用者應(yīng)該增加風(fēng)機(jī)出風(fēng)口的截面積或者在風(fēng)機(jī)吸氣側(cè)或排氣側(cè)安裝風(fēng)壓風(fēng)量調(diào)節(jié)閥這種裝置。具體操作方法如下：送風(fēng)用的入口必須加裝符合實(shí)際使用情況的過(guò)濾器，風(fēng)機(jī)設(shè)備出氣孔的總截面積應(yīng)該大于該設(shè)備出口截面積一半。若遇到水中送氣的情況，風(fēng)機(jī)的運(yùn)行時(shí)的水深壓力應(yīng)該維持在該設(shè)備型號(hào)目錄所標(biāo)注的靜壓值70%以下。風(fēng)機(jī)在加壓送氣過(guò)程中時(shí)，該設(shè)備出口溫度高于常溫10攝氏度屬于正常運(yùn)行的范圍，空氣摩擦是溫度升高的主要原因，所以應(yīng)該選用一米以上的鐵管。風(fēng)機(jī)吸風(fēng)用出口處應(yīng)該安裝消聲器，做到該設(shè)備吸入孔的總截面積大于其入口截面積二分之一以上。熟練操作對(duì)風(fēng)機(jī)過(guò)濾器的清理。輕輕旋開(kāi)設(shè)備過(guò)濾器自轉(zhuǎn)接頭，然后用空氣噴槍或者刷子除去過(guò)濾網(wǎng)上的灰塵和污垢。<br /> 看了上述內(nèi)容，對(duì)于風(fēng)機(jī)的降噪大家是不是已經(jīng)有了一定的了解呢。我公司經(jīng)營(yíng)各種類(lèi)型</span><strong style="font-family: "PingFang SC", Helvetica, "Microsoft YaHei", Arial, sans-serif; font-size:
