噴霧(wu)干(gan)燥機是一種(zhong)(zhong)可以(yi)同時完成干(gan)燥和造粒的(de)裝置(zhi)。按工藝要求(qiu)可以(yi)調節料液泵的(de)壓(ya)力、流量、噴孔的(de)大小，得到(dao)所需的(de)按一定大小比例(li)的(de)球形顆(ke)粒。噴霧(wu)干(gan)燥機為連(lian)續式常壓(ya)干(gan)燥器的(de)一種(zhong)(zhong)。用特(te)殊設(she)備將液料噴成霧(wu)狀，使其與(yu)熱(re)空氣(qi)接觸而(er)被干(gan)燥。用于干燥有些熱(re)敏(min)性的液(ye)體、懸浮(fu)液(ye)和粘滯(zhi)液(ye)體，也用(yong)于干燥燃料、中間(jian)體、肥皂粉和無機鹽等。
電(dian)(dian)容器是由兩個(ge)(ge)金屬電(dian)(dian)極，中間夾一層(ceng)電(dian)(dian)介質構成。在兩個(ge)(ge)電(dian)(dian)極之間加上電(dian)(dian)壓時(shi)，電(dian)(dian)極上就儲存(cun)電(dian)(dian)荷，所以說電(dian)(dian)容器是一種(zhong)儲能(neng)元(yuan)件，在電(dian)(dian)路(lu)中用于(yu)調諧、濾波、隔(ge)直、交流(liu)旁路(lu)和(he)能(neng)量轉(zhuan)換等(deng)。
電(dian)(dian)(dian)容(rong)(rong)器(qi)(qi)(qi)(qi)(qi)的(de)種類很多，按介(jie)質不(bu)(bu)同，可以分為(wei)空氣介(jie)質電(dian)(dian)(dian)容(rong)(rong)器(qi)(qi)(qi)(qi)(qi)。紙(zhi)質電(dian)(dian)(dian)容(rong)(rong)器(qi)(qi)(qi)(qi)(qi)，有(you)機(ji)薄膜電(dian)(dian)(dian)容(rong)(rong)器(qi)(qi)(qi)(qi)(qi)、瓷(ci)介(jie)電(dian)(dian)(dian)容(rong)(rong)器(qi)(qi)(qi)(qi)(qi)、玻璃釉電(dian)(dian)(dian)容(rong)(rong)器(qi)(qi)(qi)(qi)(qi)、云母電(dian)(dian)(dian)容(rong)(rong)器(qi)(qi)(qi)(qi)(qi)、電(dian)(dian)(dian)解(jie)電(dian)(dian)(dian)容(rong)(rong)器(qi)(qi)(qi)(qi)(qi)等。按結構不(bu)(bu)同，分為(wei)固(gu)定電(dian)(dian)(dian)容(rong)(rong)器(qi)(qi)(qi)(qi)(qi)、半可變(bian)電(dian)(dian)(dian)容(rong)(rong)器(qi)(qi)(qi)(qi)(qi)、可變(bian)電(dian)(dian)(dian)容(rong)(rong)器(qi)(qi)(qi)(qi)(qi)等。一般電(dian)(dian)(dian)容(rong)(rong)器(qi)(qi)(qi)(qi)(qi)的(de)容(rong)(rong)量(liang)及誤差都標(biao)志(zhi)在電(dian)(dian)(dian)容(rong)(rong)器(qi)(qi)(qi)(qi)(qi)上(shang)。體(ti)積(ji)較(jiao)小的(de)電(dian)(dian)(dian)容(rong)(rong)器(qi)(qi)(qi)(qi)(qi)常(chang)用數(shu)(shu)(shu)(shu)(shu)字和文字標(biao)志(zhi)。采用數(shu)(shu)(shu)(shu)(shu)字標(biao)志(zhi)容(rong)(rong)量(liang)時(shi)用三(san)位整(zheng)數(shu)(shu)(shu)(shu)(shu)，第(di)一、二(er)位為(wei)有(you)效(xiao)數(shu)(shu)(shu)(shu)(shu)字，第(di)三(san)位表示(shi)(shi)有(you)效(xiao)數(shu)(shu)(shu)(shu)(shu)字后(hou)面加零的(de)個(ge)(ge)數(shu)(shu)(shu)(shu)(shu)，單位為(wei)皮法(pF).如(ru)“223”表示(shi)(shi)該電(dian)(dian)(dian)容(rong)(rong)器(qi)(qi)(qi)(qi)(qi)的(de)容(rong)(rong)量(liang)為(wei)22000pF（或0.22?F）.需要注意的(de)是(shi)當第(di)三(san)個(ge)(ge)數(shu)(shu)(shu)(shu)(shu)為(wei)9時(shi)是(shi)個(ge)(ge)特例(li)。如(ru)“339”表示(shi)(shi)的(de)容(rong)(rong)量(liang)不(bu)(bu)是(shi)33*109pF，而是(shi)33*10-1pF（即為(wei)3.3pF）。采用文字符號標(biao)志(zhi)電(dian)(dian)(dian)容(rong)(rong)量(liang)時(shi)，將(jiang)容(rong)(rong)量(liang)的(de)整(zheng)數(shu)(shu)(shu)(shu)(shu)部(bu)分寫在容(rong)(rong)量(liang)單位標(biao)志(zhi)符號的(de)前面，小數(shu)(shu)(shu)(shu)(shu)部(bu)分放在容(rong)(rong)量(liang)單位符號的(de)后(hou)面。
額定工(gong)作(zuo)電(dian)壓是(shi)指電(dian)容器在(zai)規定的(de)工(gong)作(zuo)溫度范圍(wei)內，長期、可(ke)靠地工(gong)作(zuo)所(suo)能(neng)(neng)承受的(de)高電(dian)壓(又稱耐壓值(zhi)）。電(dian)感器又稱電(dian)感線(xian)圈，是(shi)用漆包(bao)線(xian)在(zai)絕緣(yuan)骨架上(shang)繞制在(zai)而成的(de)一種能(neng)(neng)存儲磁場能(neng)(neng)的(de)電(dian)子元器件，它在(zai)電(dian)路中(zhong)具有(you)阻(zu)(zu)交流通(tong)(tong)直(zhi)流、阻(zu)(zu)高頻通(tong)(tong)低(di)頻的(de)特性。
額(e)定(ding)功(gong)率指在(zai)規定(ding)的(de)(de)環境溫度和濕度下，假設周圍空氣不流通(tong)，在(zai)長期(qi)連續工作而(er)不損害或基(ji)本不改(gai)變電(dian)阻(zu)(zu)器性能的(de)(de)情況下，電(dian)阻(zu)(zu)器允許消耗的(de)(de)功(gong)率。標稱(cheng)阻(zu)(zu)值(zhi)(zhi)（簡(jian)稱(cheng)標稱(cheng)值(zhi)(zhi)）及允許誤(wu)差，標志在(zai)電(dian)阻(zu)(zu)器上的(de)(de)電(dian)阻(zu)(zu)值(zhi)(zhi)稱(cheng)為標稱(cheng)值(zhi)(zhi)。電(dian)阻(zu)(zu)器的(de)(de)實際阻(zu)(zu)值(zhi)(zhi)對于標稱(cheng)阻(zu)(zu)值(zhi)(zhi)的(de)(de)允許偏差范圍稱(cheng)為電(dian)阻(zu)(zu)器的(de)(de)允許誤(wu)差。它表示產品(pin)的(de)(de)精度。
噴霧(wu)干燥機電感(gan)(gan)(gan)器種(zhong)類很多(duo)，根據電感(gan)(gan)(gan)量是否(fou)可(ke)調分(fen)為固定電感(gan)(gan)(gan)器、可(ke)變電感(gan)(gan)(gan)器和(he)微調電感(gan)(gan)(gan)器；按(an)導磁(ci)體性質來(lai)分(fen)，有帶(dai)磁(ci)心和(he)不帶(dai)磁(ci)心的電感(gan)(gan)(gan)器;按(an)繞線結(jie)構來(lai)分(fen)，有單層線圈(quan)、多(duo)層線圈(quan)和(he)蜂(feng)房式線圈(quan)。
電阻的(de)種(zhong)類很多，有碳(tan)質(zhi)電阻，碳(tan)膜電阻，繞線電阻等。形式上有固定電阻，可變(bian)電阻和電位器(qi)等。
電阻(zu)溫(wen)(wen)(wen)(wen)(wen)度(du)(du)(du)系(xi)數(shu)：電流流過(guo)電阻(zu)時，溫(wen)(wen)(wen)(wen)(wen)度(du)(du)(du)升(sheng)高，其阻(zu)值發生變化，阻(zu)值變化值與原有阻(zu)值之比叫電阻(zu)的溫(wen)(wen)(wen)(wen)(wen)度(du)(du)(du)系(xi)數(shu)。對于(yu)金屬材(cai)料的電阻(zu)，電阻(zu)隨(sui)溫(wen)(wen)(wen)(wen)(wen)度(du)(du)(du)的升(sheng)高而(er)增大，是正(zheng)溫(wen)(wen)(wen)(wen)(wen)度(du)(du)(du)系(xi)數(shu)；對石磨和碳來講，電阻(zu)隨(sui)溫(wen)(wen)(wen)(wen)(wen)度(du)(du)(du)的升(sheng)高而(er)減(jian)少，是負溫(wen)(wen)(wen)(wen)(wen)度(du)(du)(du)系(xi)數(shu)。溫(wen)(wen)(wen)(wen)(wen)度(du)(du)(du)系(xi)數(shu)越小，說明(ming)電阻(zu)越穩(wen)定。
