材质 | 不锈钢 | 驱动方式 | 气动 |
用途 | Air pumpping |
kt系列油扩散真空泵是用来获得高真空(10-2~10-5pa)的主要设备。它和阀门、水冷挡板、管道、机械真空泵等组成高真空抽气系统,可获得(10-2~10-4pa)的工作真空度。如采用液氮等冷却装置,并加以烘烤可获得超高真空(10-6pa)。该泵的特点是抽气能力大,抽速从5500l/s至120000l/s范围内可供选择它增设油观察窗,注油和放油口,泵油测温装置。kt制造采用拉伸工艺,减少焊缝,增加强度,降低放气量。加热器设有电热丝和电热板两种,可供订货时选择。它被广泛地应用在真空镀膜、真空炉、电子、化工、航空、航天、冶金、材料、生物医药、原子能、宇宙探测等高科技领域。
油扩散泵油锅中的泵油在真空中加热到沸腾温度时产生大量的油蒸汽,油蒸汽经导流管由各级喷嘴定向高速喷出。由于进气口附近被抽气体的分压强高于油蒸汽流中该气体的分压强,所以被抽气体分子不断地扩散到油蒸汽流中。油蒸汽撞击被抽气体分子,使被抽气体分子沿着蒸汽流方向高速运动,气体分子碰到泵壁又反射回来再受到蒸汽流的碰撞而重新沿着蒸汽流方向流向泵壁。经过几次碰撞后,气体分子被压缩到低真空端,再由下级喷嘴喷出的蒸汽流进行多级压缩,Zui后由前级真空泵抽出,而油蒸汽在冷却的泵壁上被冷却后又返回到油锅中重新被加热,如此循环工作。
the
oil-diffused pump is another series pump e manufactured by
our company. its main work principle described here-in as
below:
pumping
oil heated in the pump oil pot to the ebullition state ( about 230
degree centigrade) is caused with evaporation and produced a large
amount of evaporated oil liquor speedily and directionally erupted
out through nozzles.
as the
branch intensity of pressure of the evacuated air nearby the inlet
is higher than that of the evaporated oil liquor, so the molecules
of the evacuated air are continuously diffused into the evaporated
oil liquor with impact on each other caused the molecules of the
evacuated air moving rapidly along the direction of movement of the
evaporated oil current. the molecules of the evacuated air are
bounced back by cylinder wall and re-impact once again on the
evaporated oil current. after several impacts, the molecules of the
evacuated air are compressed into the lower vacuum end and emptied
out by the fore pump after several compression; whereas the
evaporated oil current cooled by cylinder wall, flows back to the
heater for re-heating. the recurrence takes place again and
again.
