水環真(zhen)空(kong)泵在使用(yong)中會(hui)(hui)產生高頻放電(dian)現象。許多人可能對這種現象了解不(bu)多,但(dan)這與我們通常所說的放電(dian)現象不(bu)同。它(ta)不(bu)僅不(bu)會(hui)(hui)導(dao)致設備故障,而且有助于設備的正常運行。
水環真空泵的(de)(de)(de)(de)高(gao)頻(pin)放(fang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)是在兩(liang)(liang)個(ge)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)極(ji)(ji)之間(jian)存(cun)在高(gao)頻(pin)交變(bian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)場(chang)時(shi)引起(qi)的(de)(de)(de)(de)放(fang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)形式。當在放(fang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)管上施加交流(liu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓時(shi),氣(qi)體中的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)子(zi)(zi)(zi)(zi)(zi)(zi)和正(zheng)離(li)(li)子(zi)(zi)(zi)(zi)(zi)(zi)將在交流(liu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)場(chang)的(de)(de)(de)(de)作用(yong)下產(chan)(chan)生(sheng)(sheng)額外(wai)的(de)(de)(de)(de)共振(zhen)(zhen)。因為(wei)正(zheng)離(li)(li)子(zi)(zi)(zi)(zi)(zi)(zi)的(de)(de)(de)(de)質量比(bi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)子(zi)(zi)(zi)(zi)(zi)(zi)的(de)(de)(de)(de)質量大(da)得(de)多,所(suo)以(yi)(yi)共振(zhen)(zhen)幅(fu)度(du)(du)(du)很小(xiao)。當頻(pin)率較(jiao)低且共振(zhen)(zhen)幅(fu)度(du)(du)(du)遠大(da)于(yu)(yu)兩(liang)(liang)個(ge)極(ji)(ji)之間(jian)的(de)(de)(de)(de)距離(li)(li)時(shi),電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)子(zi)(zi)(zi)(zi)(zi)(zi)在每個(ge)半周期內(nei)經歷(li)崩潰(kui),放(fang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)和熄滅(mie)的(de)(de)(de)(de)整個(ge)過程(cheng)。此時(shi),放(fang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)情況(kuang)與直流(liu)情況(kuang)相同。當頻(pin)率更高(gao)時(shi),諧(xie)振(zhen)(zhen)的(de)(de)(de)(de)幅(fu)度(du)(du)(du)遠小(xiao)于(yu)(yu)兩(liang)(liang)個(ge)極(ji)(ji)點(dian)之間(jian)的(de)(de)(de)(de)距離(li)(li)。隨著電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)子(zi)(zi)(zi)(zi)(zi)(zi)連(lian)續地來回移動(dong),其電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)離(li)(li)能(neng)力(li)將大(da)大(da)提高(gao)。因為(wei)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)子(zi)(zi)(zi)(zi)(zi)(zi)共振(zhen)(zhen)的(de)(de)(de)(de)幅(fu)度(du)(du)(du)小(xiao),所(suo)以(yi)(yi)進入電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)極(ji)(ji)的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)子(zi)(zi)(zi)(zi)(zi)(zi)數量將大(da)大(da)減(jian)少。這(zhe)確(que)保(bao)了氣(qi)體自持放(fang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)子(zi)(zi)(zi)(zi)(zi)(zi)將不(bu)再由(you)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)極(ji)(ji)產(chan)(chan)生(sheng)(sheng)的(de)(de)(de)(de)二(er)次(ci)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)子(zi)(zi)(zi)(zi)(zi)(zi)提供,而(er)是由(you)當電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)子(zi)(zi)(zi)(zi)(zi)(zi)來回移動(dong)時(shi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)離(li)(li)產(chan)(chan)生(sheng)(sheng)的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)子(zi)(zi)(zi)(zi)(zi)(zi)提供。此時(shi),雖然(ran)也有少量的(de)(de)(de)(de)正(zheng)離(li)(li)子(zi)(zi)(zi)(zi)(zi)(zi)和光子(zi)(zi)(zi)(zi)(zi)(zi)轟擊電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)極(ji)(ji)以(yi)(yi)產(chan)(chan)生(sheng)(sheng)二(er)次(ci)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)子(zi)(zi)(zi)(zi)(zi)(zi),但由(you)于(yu)(yu)兩(liang)(liang)個(ge)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)極(ji)(ji)的(de)(de)(de)(de)極(ji)(ji)性不(bu)斷變(bian)化(hua),所(suo)以(yi)(yi)二(er)次(ci)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)子(zi)(zi)(zi)(zi)(zi)(zi)的(de)(de)(de)(de)振(zhen)(zhen)動(dong)方向有時(shi)與電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)極(ji)(ji)的(de)(de)(de)(de)方向相同。電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)子(zi)(zi)(zi)(zi)(zi)(zi)流(liu)入電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)極(ji)(ji),有時(shi)是相反的(de)(de)(de)(de)。因此,這(zhe)不(bu)利于(yu)(yu)保(bao)證(zheng)自我維持的(de)(de)(de)(de)條件(jian)。

深圳(zhen)水(shui)環真空(kong)泵高(gao)頻(pin)放(fang)(fang)電(dian)(dian)期(qi)間的點火電(dian)(dian)壓(ya)是(shi)發(fa)生(sheng)放(fang)(fang)電(dian)(dian)時施加在(zai)電(dian)(dian)極上的交(jiao)流電(dian)(dian)勢差的幅度。該(gai)電(dian)(dian)壓(ya)的幅度低(di)于直流放(fang)(fang)電(dian)(dian)的點火電(dian)(dian)壓(ya)。高(gao)頻(pin)擊(ji)穿電(dian)(dian)場強度與氣壓(ya)有關。壓(ya)力(li)越高(gao),擊(ji)穿電(dian)(dian)場的強度越大,擊(ji)穿頻(pin)率越高(gao)。高(gao)頻(pin)放(fang)(fang)電(dian)(dian)被(bei)廣泛(fan)應用于雷(lei)達和脈沖(chong)技術中。
水(shui)環真空泵(beng)可(ke)以通過高(gao)頻放電現象形成穩(wen)定的無(wu)線電波,還(huan)可(ke)以避免(mian)靜電荷的影響。因此,它(ta)有(you)助于提高(gao)設備(bei)的工(gong)作效率(lv),使(shi)設備(bei)能夠長時間平穩(wen)運行,并減(jian)少損耗,從而可(ke)以節省能源并降(jiang)低排放效果。
