費(fèi)斯托festo脈沖電磁閥的技術(shù)
費(fèi)斯托festo脈沖電磁閥通過導(dǎo)線將電磁閥體內(nèi)線圈輸入正向脈沖信號(hào),線圈產(chǎn)生的工作磁通,使動(dòng)芯吸合,打開閥門。當(dāng)停止正向脈沖信號(hào)輸入時(shí),動(dòng)芯釋放,動(dòng)芯在彈簧力的作用下回復(fù)到初始狀態(tài),關(guān)閉閥門,另外有自保持型的,停止輸入正向脈沖或斷電后也能保持,需要輸入負(fù)向脈沖信號(hào)才能復(fù)位。費(fèi)斯托festo脈沖電磁閥的工作原理是利用電器的脈沖轉(zhuǎn)化為機(jī)械的脈動(dòng)使得脈動(dòng)氣體的強(qiáng)大能量變成動(dòng)量在短時(shí)間內(nèi)釋放產(chǎn)生巨大沖力,用plc控制其脈沖的間隔應(yīng)根據(jù)額定氣體壓力恢復(fù)時(shí)間來確定.
用途:一般安裝在主油路或減振器背壓油路中,在變速器自動(dòng)升檔及降檔的瞬間或在鎖止離合器鎖止及解除鎖止動(dòng)作開始時(shí)使油壓下降,以減少換檔和鎖止解鎖沖擊,使車輛運(yùn)行更加平衡。
其作用是控制油路中油壓的大小。
原理:
里有密閉的腔,在不同位置開有通孔,每個(gè)孔都通向不同的油管,腔中間是閥,
兩面是兩塊電磁鐵,哪面的磁鐵線圈通電閥體就會(huì)被吸引到哪邊,通過控制閥體的移動(dòng)來
檔住或漏出不同的排油的孔。
