四柱液壓機的降噪方法
四柱液壓機在使用時會(hui)產生(sheng)巨大(da)的噪音,在(zai)日常使用中(zhong)會(hui)對(dui)周(zhou)圍造成一定的影(ying)響(xiang)。那么針對(dui)這些噪音我們應該怎么辦呢?
1.選用低噪(zao)聲液壓元件(jian)
具體措施:選用低(di)噪聲(sheng)液(ye)壓(ya)泵和控制閥;降(jiang)低(di)液(ye)壓(ya)泵轉速,目標:降(jiang)低(di)單(dan)個液(ye)壓(ya)元(yuan)件(jian)的噪聲(sheng)
2.降低機械噪聲
具體措施:提高液壓機液壓泵(beng)組(zu)(zu)加工(gong)、安裝精度、采用(yong)(yong)撓性聯軸器(qi),采用(yong)(yong)無管話集成連接;采用(yong)(yong)隔振(zhen)體、防振(zhen)墊、泵(beng)進、出口使用(yong)(yong)軟管段;液壓泵(beng)組(zu)(zu)與油(you)箱(xiang)分(fen)離;油(you)箱(xiang)設加強筋;合理確定(ding)管長(chang),配(pei)置(zhi)管夾
3.降低流體噪聲
使(shi)液(ye)(ye)壓(ya)(ya)機元件(jian)及管(guan)(guan)件(jian)密封良好,防止(zhi)空氣(qi)(qi)進入液(ye)(ye)壓(ya)(ya)系統;排除已混入系統的空氣(qi)(qi);采(cai)(cai)用(yong)防噪(zao)(zao)聲(sheng)(sheng)油(you)箱結構;合理配管(guan)(guan),油(you)箱安(an)裝高(gao)于液(ye)(ye)壓(ya)(ya)泵(beng)(beng),改善泵(beng)(beng)吸油(you)系能;壓(ya)(ya)力閥(fa)逐漸降(jiang)低;增設泄油(you)節流(liu)閥(fa)或設置卸壓(ya)(ya)回路;降(jiang)低換向閥(fa)換向速度,采(cai)(cai)用(yong)直流(liu)電(dian)磁鐵;改變管(guan)(guan)道長度和管(guan)(guan)夾位置;采(cai)(cai)用(yong)蓄(xu)能器和消聲(sheng)(sheng)器隔聲(sheng)(sheng)吸聲(sheng)(sheng) ;把液(ye)(ye)壓(ya)(ya)泵(beng)(beng)或整(zheng)個(ge)液(ye)(ye)壓(ya)(ya)站罩起來,把泵(beng)(beng)侵在油(you)中,合理選用(yong)材料,阻(zu)止(zhi)噪(zao)(zao)聲(sheng)(sheng)在空氣(qi)(qi)中傳播(bo);吸收噪(zao)(zao)聲(sheng)(sheng)、減小噪(zao)(zao)聲(sheng)(sheng)。
