導熱油泵的(de)(de)抽空有兩個主要(yao)條(tiao)件,即(ji)氣(qi)(qi)蝕引(yin)起的(de)(de)抽空和(he)氣(qi)(qi)體(ti)侵(qin)入(ru)引(yin)起的(de)(de)抽空。在(zai)氣(qi)(qi)蝕的(de)(de)抽空條(tiao)件下,只要(yao)輸送介質的(de)(de)工(gong)作(zuo)壓(ya)(ya)力(li)低于(yu)工(gong)作(zuo)溫(wen)度(du)下的(de)(de)飽和(he)蒸汽壓(ya)(ya)力(li),它就會翻滾并構成(cheng)排空,而不(bu)(bu)一定(ding)都是真空。典型(xing)的(de)(de)例(li)如輕烴泵密(mi)封件被(bei)抽空。在(zai)氣(qi)(qi)體(ti)侵(qin)入(ru)的(de)(de)疏(shu)散條(tiao)件下,氣(qi)(qi)體(ti)侵(qin)入(ru)主要(yao)有以下幾(ji)條(tiao)路(lu)徑(jing)。一是內部(bu)氣(qi)(qi)體(ti)進入(ru)離心式熱油泵,如管(guan)道(dao)中(zhong)收集的(de)(de)裂解氣(qi)(qi)。另一種是外部(bu)空氣(qi)(qi)進入(ru)離心機熱油泵,主要(yao)是一個減壓(ya)(ya)系(xi)統(tong),空氣(qi)(qi)通過(guo)泵和(he)管(guan)道(dao)的(de)(de)法蘭(lan)或壓(ya)(ya)蓋進入(ru)泵內;在(zai)這種情況下,泵可(ke)以構成(cheng)負(fu)壓(ya)(ya)。但實際(ji)上,即(ji)使形(xing)成(cheng)負(fu)壓(ya)(ya),泵表(biao)(biao)面(mian)之間的(de)(de)壓(ya)(ya)差也(ye)不(bu)(bu)會超(chao)過(guo)1Kg/cm2(軸的(de)(de)直徑(jing)為Φ45~70mm)。考慮到抽空,大氣(qi)(qi)壓(ya)(ya)力(li)可(ke)以作(zuo)用在(zai)動(dong)靜環整個投影面(mian)積上,但是在(zai)具體(ti)計算之后,已知表(biao)(biao)中(zhong)的(de)(de)壓(ya)(ya)力(li)差不(bu)(bu)能大于(yu)彈簧力(li)來推(tui)開密(mi)封表(biao)(biao)面(mian)。
