液壓馬達工作時産生噪聲的4個原因
1、因爲液壓系統侵入空氣時,在低壓區其體積較大,當流到高壓區時受壓縮,體積突然縮小,而當它流入低壓區時,體積突然增大,這種氣泡體積的突然改變,産生“爆炸”現象,因而産生噪聲,此現象通常稱爲“空穴”。空氣侵入液壓系統是産生噪聲的主要原因。解決問題的辦法:常常在液壓缸上設置排氣裝置,以便排氣。另外在開車后,使執行件以快速全行程往複幾次排氣,也是常用的方法:
液壓泵或液壓馬達質量不好,通常是液壓傳動中産生噪聲的主要部分。液壓泵的制造質量不好,精度不符合技術要求,壓力與流量波動大,困油現象未能很好消除,密封不好,以及軸承質量差等都是造成噪聲的主要原因。在使用中,由于液壓泵零件磨損,間隙過大,流量不足,壓力易波動,同樣也會引起噪聲。面對上述原因,一是選擇質量好的液壓泵或液壓馬達,二是加強維修和保養,例如若齒輪的齒形精度低,則應對研齒輪,滿足接觸面要求;若葉片泵有困油現象,則應修正配油盤的三角槽,消除困油;若液壓泵軸向間隙過大而輸油量不足,則應修理,使軸向間隙在允許范圍內;若液壓泵選用不對,則應更換;在工作時,液壓閥的閥芯支持在彈簧上,當其頻率與液壓泵輸油率的脈動頻率或與其它振源頻率相近時,會引起振動,産生噪聲。這時,通過改變管路系統的固有頻率,變動控制閥的位置或適當地加蓄能器,則能防振降噪。
2、溢流閥不穩定,如由于滑閥與閥孔配合不當或錐閥與閥座接觸處被污物卡住、阻尼孔堵塞、彈簧歪斜或失效等使閥芯卡住或在閥孔內移動不靈,引起系統壓力波動和噪聲。對此,應注意清洗、疏通陰尼孔;對溢流閥進行檢查,如發現有損壞,或因磨損超過規定,則應及時修理或更換。
3、換向閥調整不當,使換向閥閥芯移動太快,造成換向沖擊,因而産生噪聲與振動。在這種情況下,若換向閥是液壓換向閥,則應調整控制油路中的節流元件,使換向平穩無沖擊。
4、機械振動,如油管細長,彎頭多而未加固定,在油流通過時,特別是當流速較高時,容易引起管子抖動;電動機和液壓泵的旋轉部分不平衡,或在安裝時對中不好,或聯軸節松動等,均能産生振動和噪聲。對此應采取的措施有:較長油管應彼此分開,并與機床壁隔開,適當加設支承管夾;調整電動機和液壓泵的安裝精度;重新安裝聯軸節,保證同軸度小于0.1MM等。
