  真空泵是一种利用机械或物理化学的方法对密闭容器进行抽气而获取真空的装置设备,本质上就是一种真空获取装置。真空泵是一个很大的行业,真空泵种类可谓是琳琅满目,不同的真空泵分类有不同的特点仪满足不同的使用环境和工况。今天河南J9九游会AG来为您科普真空泵种类有哪些。

真空泵分类

J9九游会AG真空泵分类

  真空(kong)泵分类(lei)可(ke)以按照三个维度(du)(du)来进(jin)行,分别是工(gong)作(zuo)原(yuan)理、真空(kong)度(du)(du)和结构特点。

  真(zhen)空(kong)(kong)(kong)泵(beng)种(zhong)(zhong)类(按(an)照工作原理):可分(fen)为气(qi)(qi)体(ti)(ti)(ti)(ti)转移式(shi)真(zhen)空(kong)(kong)(kong)泵(beng)和(he)气(qi)(qi)体(ti)(ti)(ti)(ti)捕获式(shi)真(zhen)空(kong)(kong)(kong)泵(beng)。气(qi)(qi)体(ti)(ti)(ti)(ti)转移泵(beng)是(shi)一种(zhong)(zhong)能使气(qi)(qi)体(ti)(ti)(ti)(ti)不断地吸(xi)人和(he)排(pai)出借以达到(dao)抽气(qi)(qi)目的(de)的(de)真(zhen)空(kong)(kong)(kong)泵(beng)。该种(zhong)(zhong)真(zhen)空(kong)(kong)(kong)泵(beng)有变容真(zhen)空(kong)(kong)(kong)泵(beng)和(he)动量传输泵(beng)两种(zhong)(zhong)类型(xing)。气(qi)(qi)体(ti)(ti)(ti)(ti)捕获泵(beng)是(shi)一种(zhong)(zhong)使气(qi)(qi)体(ti)(ti)(ti)(ti)分(fen)子被(bei)吸(xi)附或凝结在(zai)泵(beng)的(de)内表面(mian)上从而减小了(le)容器内气(qi)(qi)体(ti)(ti)(ti)(ti)分(fen)子数(shu)目而达到(dao)抽气(qi)(qi)目的(de)的(de)真(zhen)空(kong)(kong)(kong)泵(beng)。其(qi)中(zhong)活(huo)塞式(shi)真(zhen)空(kong)(kong)(kong)泵(beng)、旋片式(shi)真(zhen)空(kong)(kong)(kong)泵(beng)、分(fen)子真(zhen)空(kong)(kong)(kong)泵(beng)、螺(luo)杆式(shi)真(zhen)空(kong)(kong)(kong)泵(beng)、喷射真(zhen)空(kong)(kong)(kong)泵(beng)、扩散(san)泵(beng)等是(shi)几种(zhong)(zhong)有代表性的(de)泵(beng)型(xing)。

  真(zhen)(zhen)空(kong)(kong)(kong)泵(beng)(beng)种类(按照真(zhen)(zhen)空(kong)(kong)(kong)度):目前真(zhen)(zhen)空(kong)(kong)(kong)技(ji)术设计的压力范围达(da)100~10-16kPa。这么宽的压力范围除(chu)了粗(cu)真(zhen)(zhen)空(kong)(kong)(kong)和低真(zhen)(zhen)空(kong)(kong)(kong)可(ke)以用一种真(zhen)(zhen)空(kong)(kong)(kong)泵(beng)(beng)获得外,高(gao)真(zhen)(zhen)空(kong)(kong)(kong)以上的领域必须(xu)应用两(liang)种以上真(zhen)(zhen)空(kong)(kong)(kong)泵(beng)(beng)机(ji)组来完成。按照真(zhen)(zhen)空(kong)(kong)(kong)度从高(gao)/超真(zhen)(zhen)空(kong)(kong)(kong)到粗(cu)/低真(zhen)(zhen)空(kong)(kong)(kong),真(zhen)(zhen)空(kong)(kong)(kong)泵(beng)(beng)大致可(ke)分(fen)14大类:即(ji)高(gao)/超真(zhen)(zhen)空(kong)(kong)(kong)一低温泵(beng)(beng)、分(fen)子(zi)泵(beng)(beng)、溅射(she)离子(zi)泵(beng)(beng)、钛(tai)升华泵(beng)(beng)、扩散泵(beng)(beng)、中真(zhen)(zhen)空(kong)(kong)(kong)一干泵(beng)(beng)、双级旋片泵(beng)(beng)、罗茨泵(beng)(beng)、油增(zeng)压泵(beng)(beng)、水(shui)蒸气喷射(she)泵(beng)(beng)、粗(cu)/低真(zhen)(zhen)空(kong)(kong)(kong)一单级旋片泵(beng)(beng)、滑阀泵(beng)(beng)、液环泵(beng)(beng)、往复式真(zhen)(zhen)空(kong)(kong)(kong)泵(beng)(beng)。

  真(zhen)(zhen)空(kong)泵(beng)(beng)分(fen)类(lei)(按照结构特点):可(ke)分(fen)为机械式(shi)真(zhen)(zhen)空(kong)泵(beng)(beng)和射流式(shi)真(zhen)(zhen)空(kong)泵(beng)(beng)。在(zai)各种真(zhen)(zhen)空(kong)设(she)备中凡使(shi)用机械运(yun)(yun)动(dong)(转(zhuan)动(dong)或滑动(dong))不断(duan)改变泵(beng)(beng)内吸(xi)气(qi)容腔(qiang)的(de)容积(ji)而获得真(zhen)(zhen)空(kong)的(de)泵(beng)(beng)常称机械真(zhen)(zhen)空(kong)泵(beng)(beng)。机械式(shi)容积(ji)真(zhen)(zhen)空(kong)泵(beng)(beng)靠(kao)机械运(yun)(yun)动(dong)使(shi)泵(beng)(beng)腔(qiang)工作容积(ji)周期变化来实现抽气(qi)作用的(de)是(shi)机械式(shi)容积(ji)真(zhen)(zhen)空(kong)泵(beng)(beng)。属于这类(lei)泵(beng)(beng)的(de)有往复式(shi)真(zhen)(zhen)空(kong)泵(beng)(beng)、旋转(zhuan)式(shi)机械泵(beng)(beng)(包括(kuo)旋片式(shi)、螺杆式(shi)、罗茨式(shi)、液环式(shi)等)。这类(lei)泵(beng)(beng)中除机械增压泵(beng)(beng)外一般均可(ke)单独使(shi)用。

  喷(pen)(pen)射真空泵是由喷(pen)(pen)嘴、吸入(ru)室(shi)、扩(kuo)压(ya)管三部分组成。其本(ben)身没(mei)有(you)运动部件,利(li)用流体传递能量(liang)和质量(liang)。它利(li)用具有(you)一定(ding)压(ya)力的(de)(de)工作流体通过喷(pen)(pen)嘴高速喷(pen)(pen)出(chu),通过能量(liang)转换(huan)在喷(pen)(pen)嘴出(chu)口形成真空从而将被抽(chou)介(jie)质吸引出(chu)来,两股介(jie)质在扩(kuo)压(ya)管内进行混合及(ji)能量(liang)交换(huan)最(zui)后以略(lve)高于大(da)气(qi)压(ya)而排(pai)出(chu)。属于这(zhei)类泵的(de)(de)有(you)水蒸(zheng)气(qi)喷(pen)(pen)射泵、空气(qi)喷(pen)(pen)射泵、水喷(pen)(pen)射泵以及(ji)各种扩(kuo)散泵等。

  以上就是真空泵分类的介绍,我公司真空泵种类有循环水真空泵、旋片式真空泵、隔膜泵等,以上皆可搭配旋转蒸发仪和玻璃反应釜配套使用。询价请拨打电话0371-67447999。
