管式離心機的轉頭安(an)裝及保養

離心轉(zhuan)(zhuan)(zhuan)(zhuan)頭(tou)是(shi)(shi)(shi)用來(lai)擱置樣(yang)品(pin)容器的支(zhi)架(jia),有角式轉(zhuan)(zhuan)(zhuan)(zhuan)頭(tou)與(yu)甩平(ping)式轉(zhuan)(zhuan)(zhuan)(zhuan)頭(tou)兩種。角式轉(zhuan)(zhuan)(zhuan)(zhuan)頭(tou)計(ji)劃有孔(kong)穴(xue),與(yu)旋轉(zhuan)(zhuan)(zhuan)(zhuan)軸心之間(jian)的角度在之間(jian),其孔(kong)穴(xue)是(shi)(shi)(shi)用來(lai)安排樣(yang)品(pin)容器。角式轉(zhuan)(zhuan)(zhuan)(zhuan)頭(tou)在管(guan)式離心機(ji)高(gao)速旋轉(zhuan)(zhuan)(zhuan)(zhuan)時不會產(chan)生相對活(huo)動(dong)。甩平(ping)式轉(zhuan)(zhuan)(zhuan)(zhuan)頭(tou)橫臂(bei)上(shang)懸掛著個可自由活(huo)動(dong)的吊桶(tong),吊桶(tong)內安排樣(yang)品(pin)容器,1樣(yang)平(ping)常是(shi)(shi)(shi)離心試(shi)管(guan)。當啟動(dong)管(guan)式離心機(ji)后轉(zhuan)(zhuan)(zhuan)(zhuan)速到達時,吊桶(tong)從下垂狀(zhuang)態漸(jian)(jian)漸(jian)(jian)上(shang)升并(bing)與(yu)轉(zhuan)(zhuan)(zhuan)(zhuan)軸橫臂(bei)持平(ping),以是(shi)(shi)(shi)稱(cheng)為甩平(ping)式轉(zhuan)(zhuan)(zhuan)(zhuan)頭(tou)。制造轉(zhuan)(zhuan)(zhuan)(zhuan)頭(tou)的質料有鋁(lv)合金(jin)與(yu)鈦合金(jin)等,要(yao)是(shi)(shi)(shi)需(xu)(xu)求(qiu)管(guan)式離心機(ji)中低速運轉(zhuan)(zhuan)(zhuan)(zhuan),則利(li)用鋁(lv)合金(jin)轉(zhuan)(zhuan)(zhuan)(zhuan)頭(tou);要(yao)是(shi)(shi)(shi)需(xu)(xu)求(qiu)高(gao)速運轉(zhuan)(zhuan)(zhuan)(zhuan)則要(yao)利(li)用鈦合金(jin)轉(zhuan)(zhuan)(zhuan)(zhuan)頭(tou)。

管(guan)式(shi)(shi)離(li)(li)心機(ji)(ji)的轉(zhuan)頭是(shi)(shi)(shi)安置(zhi)在(zai)管(guan)式(shi)(shi)離(li)(li)心機(ji)(ji)的離(li)(li)心室內。由制(zhi)(zhi)冷(leng)機(ji)(ji)運送出(chu)的制(zhi)(zhi)冷(leng)劑對離(li)(li)心室降溫(wen),離(li)(li)心室安置(zhi)有(you)熱電(dian)偶溫(wen)度檢測器,其作用是(shi)(shi)(shi)舉行溫(wen)度控制(zhi)(zhi)。在(zai)設定的溫(wen)度范疇內,管(guan)式(shi)(shi)離(li)(li)心機(ji)(ji)高(gao)(gao)速(su)(su)事情(qing)時料(liao)液(ye)溫(wen)度始終(zhong)不會高(gao)(gao)于(yu),克制(zhi)(zhi)了藥物(wu)(wu)的生物(wu)(wu)活性的傷失(shi)。 高(gao)(gao)速(su)(su)冷(leng)凍管(guan)式(shi)(shi)離(li)(li)心機(ji)(ji)轉(zhuan)速(su)(su)可達,疏(shu)散因數,疏(shu)散成績(ji)好,是(shi)(shi)(shi)當代生物(wu)(wu)制(zhi)(zhi)藥工(gong)業廣(guang)為利用的疏(shu)散配(pei)置(zhi)。
