【刨花板秸稈板設備廠家】熱(re)(re)壓(ya)(ya)(ya)機(ji)液壓(ya)(ya)(ya)系(xi)(xi)(xi)統(tong)(tong)(tong)簡介，在(zai)(zai)液壓(ya)(ya)(ya)系(xi)(xi)(xi)統(tong)(tong)(tong)方(fang)(fang)面(mian)(mian),目前的(de)(de)趨(qu)勢是越(yue)(yue)來越(yue)(yue)多(duo)(duo)地采用(yong)油(you)作介質。因它(ta)更便(bian)于(yu)(yu)操作及(ji)實現自動(dong)控制,且其各種控制元(yuan)件標準(zhun)化、系(xi)(xi)(xi)列化,供應(ying)方(fang)(fang)便(bian)。在(zai)(zai)多(duo)(duo)層壓(ya)(ya)(ya)機(ji)上近來則(ze)越(yue)(yue)來越(yue)(yue)多(duo)(duo)地采用(yong)蓄壓(ya)(ya)(ya)罐與泵(beng)聯合(he)傳動(dong)的(de)(de)形式以獲得(de)更高的(de)(de)閉(bi)合(he)速度(du)。在(zai)(zai)加(jia)熱(re)(re)系(xi)(xi)(xi)統(tong)(tong)(tong)方(fang)(fang)面(mian)(mian),各國現仍通用(yong)蒸汽加(jia)熱(re)(re),也有電(dian)加(jia)熱(re)(re)的(de)(de)方(fang)(fang)式。然而近十年來正逐(zhu)漸(jian)向(xiang)液體(過(guo)熱(re)(re)水、導熱(re)(re)油(you))加(jia)熱(re)(re)方(fang)(fang)向(xiang)發展(zhan)。它(ta)的(de)(de)優點(dian)是熱(re)(re)容(rong)量(liang)高,溫(wen)度(du)均勻,熱(re)(re)負荷波動(dong)小,易于(yu)(yu)得(de)到更高溫(wen)度(du)而管(guan)道(dao)壓(ya)(ya)(ya)力大大降(jiang)低(di),熱(re)(re)損耗少等等,因而使生產成本降(jiang)低(di)。在(zai)(zai)電(dian)加(jia)熱(re)(re)方(fang)(fang)面(mian)(mian),除用(yong)電(dian)熱(re)(re)元(yuan)件直接加(jia)熱(re)(re)外,還有用(yong)高頻加(jia)熱(re)(re)方(fang)(fang)法(fa)的(de)(de),但由于(yu)(yu)能耗不低(di)、運行成本相當高,而未見有大規模發展(zhan)的(de)(de)趨(qu)勢。
