  • 壓縮機的分類有哪些？

    壓(ya)(ya)(ya)縮(suo)機(ji)(ji)(ji)按其(qi)原理可分(fen)為(wei)(wei)容積型(xing)壓(ya)(ya)(ya)縮(suo)機(ji)(ji)(ji)與速度(du)型(xing)壓(ya)(ya)(ya)縮(suo)機(ji)(ji)(ji)。容積型(xing)又分(fen)為(wei)(wei)：往(wang)復式(shi)(shi)(shi)壓(ya)(ya)(ya)縮(suo)機(ji)(ji)(ji)、回轉式(shi)(shi)(shi)壓(ya)(ya)(ya)縮(suo)機(ji)(ji)(ji)；速度(du)型(xing)壓(ya)(ya)(ya)縮(suo)機(ji)(ji)(ji)又分(fen)為(wei)(wei)：軸流式(shi)(shi)(shi)壓(ya)(ya)(ya)縮(suo)機(ji)(ji)(ji)、離心式(shi)(shi)(shi)壓(ya)(ya)(ya)縮(suo)機(ji)(ji)(ji)和混(hun)流式(shi)(shi)(shi)壓(ya)(ya)(ya)縮(suo)機(ji)(ji)(ji)。如今家(jia)用(yong)(yong)冰(bing)箱和空(kong)調器壓(ya)(ya)(ya)縮(suo)機(ji)(ji)(ji)都是容積式(shi)(shi)(shi)，其(qi)中又可分(fen)為(wei)(wei)往(wang)復式(shi)(shi)(shi)和旋(xuan)轉式(shi)(shi)(shi)。往(wang)復式(shi)(shi)(shi)壓(ya)(ya)(ya)縮(suo)機(ji)(ji)(ji)使用(yong)(yong)的(de)是活(huo)塞(sai)(sai)、曲(qu)(qu)柄、連(lian)桿機(ji)(ji)(ji)構或活(huo)塞(sai)(sai)、曲(qu)(qu)柄、滑管機(ji)(ji)(ji)構，旋(xuan)轉式(shi)(shi)(shi)使用(yong)(yong)的(de)多是滾動(dong)轉子壓(ya)(ya)(ya)縮(suo)機(ji)(ji)(ji)。在(zai)商用(yong)(yong)空(kong)調上，又多是離心式(shi)(shi)(shi)、渦旋(xuan)式(shi)(shi)(shi)、螺桿式(shi)(shi)(shi)。按應用(yong)(yong)范圍(wei)又可分(fen)為(wei)(wei)低背壓(ya)(ya)(ya)式(shi)(shi)(shi)、中背壓(ya)(ya)(ya)式(shi)(shi)(shi)、高背

  • 工業自動化的意義是什么？

    基本的(de)(de)自(zi)動(dong)化定義(yi)是(shi)使用(yong)技術代替人類勞(lao)動(dong)。這(zhe)可以在工(gong)(gong)(gong)廠(chang)(chang)或小企業(ye)中完成——規模與定義(yi)無(wu)關。在工(gong)(gong)(gong)作場(chang)所引入各種機(ji)器都(dou)是(shi)自(zi)動(dong)化的(de)(de)一種形(xing)式。如果我們(men)認為在工(gong)(gong)(gong)廠(chang)(chang)車間增加機(ji)器是(shi)機(ji)械化的(de)(de)第一步(bu)，那么(me)工(gong)(gong)(gong)業(ye)自(zi)動(dong)化就是(shi)第二步(bu)。在提高(gao)生產和工(gong)(gong)(gong)人安全方面(mian)，機(ji)器無(wu)疑是(shi)有用(yong)的(de)(de)。然而，這(zhe)些系統的(de)(de)局限性與負責(ze)操(cao)作它們(men)的(de)(de)人相匹配。例如，裝配線上(shang)的(de)(de)一臺機(ji)器需要持續的(de)(de)監(jian)督。這(zhe)是(shi)一個靜(jing)態的(de)(de)設(she)備，必須監(jian)測損壞和變化。它是(shi)不(bu)靈活的(de)(de)，通常(chang)需要持

  • 使用工業自動化的優點

    我們將(jiang)探討工(gong)(gong)(gong)業(ye)自動(dong)化(hua)的五個(ge)主要優勢:安全(quan)性、靈活(huo)性、一致(zhi)性、生產率和(he)可負擔(dan)性。你(ni)很快就(jiu)會看到，這些(xie)都是(shi)全(quan)球公司越來越依賴自動(dong)化(hua)制造的關鍵原(yuan)因。安全(quan)性工(gong)(gong)(gong)作場所(suo)的安全(quan)是(shi)所(suo)有工(gong)(gong)(gong)作場所(suo)的必要條件。然而，監控和(he)維護(hu)機(ji)(ji)器(qi)(qi)(qi)有時后會挺危險。安全(quan)籠的破損或設備故障(zhang)都很容(rong)易導致(zhi)工(gong)(gong)(gong)人受傷(shang)。工(gong)(gong)(gong)業(ye)自動(dong)化(hua)技術可以(yi)大大減少現場事故的數量。機(ji)(ji)器(qi)(qi)(qi)人配(pei)備了傳感器(qi)(qi)(qi)，可以(yi)與人類一起(qi)安全(quan)地工(gong)(gong)(gong)作，如果機(ji)(ji)器(qi)(qi)(qi)出現潛在問題，計(ji)算機(ji)(ji)可以(yi)提(ti)醒工(gong)(gong)(gong)人。這

  • 空調壓縮機的作用和工作原理

    空(kong)(kong)調壓(ya)(ya)(ya)(ya)(ya)縮(suo)(suo)機(ji)(ji)在空(kong)(kong)調制(zhi)冷(leng)(leng)(leng)劑回路中(zhong)起著壓(ya)(ya)(ya)(ya)(ya)縮(suo)(suo)和驅動制(zhi)冷(leng)(leng)(leng)劑的(de)作用。空(kong)(kong)調壓(ya)(ya)(ya)(ya)(ya)縮(suo)(suo)機(ji)(ji)一般安(an)裝在室外機(ji)(ji)中(zhong)。空(kong)(kong)調壓(ya)(ya)(ya)(ya)(ya)縮(suo)(suo)機(ji)(ji)從低壓(ya)(ya)(ya)(ya)(ya)區抽取制(zhi)冷(leng)(leng)(leng)劑，送至高壓(ya)(ya)(ya)(ya)(ya)區降溫冷(leng)(leng)(leng)凝。薄片將熱(re)量散發到空(kong)(kong)氣中(zhong)，制(zhi)冷(leng)(leng)(leng)劑也由氣態變為液態，壓(ya)(ya)(ya)(ya)(ya)力增加(jia)。壓(ya)(ya)(ya)(ya)(ya)縮(suo)(suo)機(ji)(ji)冷(leng)(leng)(leng)凝器(qi)節流裝置蒸發器(qi)加(jia)熱(re)和制(zhi)冷(leng)(leng)(leng)原理(li)相(xiang)同，即(ji)逆卡諾循環，區別(bie)于制(zhi)冷(leng)(leng)(leng)原理(li)是冷(leng)(leng)(leng)凝器(qi)和蒸發器(qi)互換，即(ji)壓(ya)(ya)(ya)(ya)(ya)縮(suo)(suo)機(ji)(ji)蒸發器(qi)節流裝置冷(leng)(leng)(leng)凝器(qi)壓(ya)(ya)(ya)(ya)(ya)縮(suo)(suo)機(ji)(ji)是制(zhi)冷(leng)(leng)(leng)系統的(de)心臟，無論是它(ta)是空(kong)(kong)調、冷(leng)(leng)(leng)庫、化學(xue)制(zhi)冷(leng)(leng)(leng)工藝等，必(bi)須(xu)要有它(ta)。空(kong)(kong)調壓(ya)(ya)(ya)(ya)(ya)縮(suo)(suo)
