工業(yè)生產(chǎn)車間的換氣次數(shù)如何計(jì)算(選擇新風(fēng)柜必備)工業(yè)生產(chǎn)車間的換氣次數(shù)參考:1.換氣次數(shù)的定義:換氣次數(shù)(次/小時(shí))=室內(nèi)總送風(fēng)量(m/h)(室內(nèi)面積(㎡)室內(nèi)的高度(m));一般環(huán)境要求換風(fēng)量為25~3次/小時(shí);密集的公共場所,要求換風(fēng)量為3~4次/小時(shí);密集且有高溫的場所或生產(chǎn)車間,要求換風(fēng)量為4~5次/小時(shí);高溫及有嚴(yán)重污染的生產(chǎn)車間,要求換風(fēng)量為5~6次/小時(shí);在較潮濕的南方地區(qū),換氣次數(shù)應(yīng)適當(dāng)增加,而較炎熱干燥的北方地方則可適當(dāng)減小換氣數(shù)。SICK C20E-105303A11 光柵

煤矸石粉碎機(jī)生產(chǎn)率的三種不同計(jì)算規(guī)律煤矸石粉碎機(jī)生產(chǎn)率指粉碎過程中煤矸石粉碎機(jī)單位時(shí)間內(nèi)處理的物料量。根據(jù)具體條件和計(jì)算目的的不同,煤矸石粉碎機(jī)生產(chǎn)率有不同的計(jì)算方法,如:按原礦計(jì)煤矸石粉碎機(jī)單位時(shí)間處理量和煤矸石粉碎機(jī)利用系數(shù);按粒級計(jì)煤矸石粉碎機(jī)利用系數(shù)。按原礦計(jì)每臺煤矸石粉碎機(jī)單位時(shí)間的處理量,又分按年計(jì)和按小時(shí)計(jì)兩種。這種方法簡便、直觀。同一選礦廠中,如果礦石性質(zhì)、給料粒度和產(chǎn)品粒度相同,可依此評價(jià)每臺煤矸石粉碎機(jī)的生產(chǎn)狀況。
