香蕉国产精品偷在看视频_潔凈室壓差控制方法-鄭州豫潔環(huán)?？萍加邢薰?/title> <meta name="keywords" content="河南凈化工程" /> <meta name="description" content="為了達到潔凈室內潔凈度的要求，平時(shí)需要維持一定的正壓值，對不同等級的潔凈室或潔凈區，與非潔凈區之間的靜壓差不應小于5Pa，潔凈區與室外靜壓差不應小于10Pa.維持潔凈室正壓的方法有：（1）安裝余壓閥：即在潔凈室的下風(fēng)向側的墻七安裝，預先調整余壓閥維持室內正壓值的開(kāi)啟度，通過(guò)余壓閥開(kāi)啟關(guān)閉調整維持正壓值，采用余壓閥時(shí)應注意長(cháng)期使用…"

為了達到潔凈室內潔凈度的要求，平時(shí)需要維持一定的正壓值，對不同等級的潔凈室或潔凈區，與非潔凈區之間的靜壓差不應小于5Pa，潔凈區與室外靜壓差不應小于10Pa.維持潔凈室正壓的方法有： </p> <p style="text-indent:2em;"> （1）安裝余壓閥：即在潔凈室的下風(fēng)向側的墻七安裝，預先調整余壓閥維持室內正壓值的開(kāi)啟度，通過(guò)余壓閥開(kāi)啟關(guān)閉調整維持正壓值，采用余壓閥時(shí)應注意長(cháng)期使用會(huì )關(guān)閉不嚴。 </p> <p style="text-indent:2em;"> （2）送風(fēng)量大于回風(fēng)量的方法維持室內正壓。 </p> <p style="text-indent:2em;"> （3）通過(guò)安裝在回風(fēng)口或支風(fēng)管道上的對開(kāi)式多葉調節閥來(lái)維持室內止值。這種方法簡(jiǎn)單方便，但精細度不如余壓閥高。 </p> <p style="text-indent:2em;"> （4）在回風(fēng)口處安裝空氣阻尼層，阻尼層材料有尼龍紗、尼龍篩網(wǎng)（孔眼>100目）、在堿液中浸泡過(guò)的中細孔泡沫塑料、無(wú)紡布等、即通過(guò)回風(fēng)阻尼層阻力逐漸增加而使室內正壓增加。該種方法只適用于走廊或套間回風(fēng)方式。 </p> <p style="text-indent:2em;"> （5）要求潔凈室（區）外圍護結構密封性能良好。
