山東裝載機http://m.lcsqtax.cn/在工作3000小時之后，會出現儀表臺、駕駛室抖動現象，且抖動現象越來越嚴重，以至駕駛室、整機也產生抖動。抖動現象造成該機物料稱重不準確，無法正常使用。下面永保機械的技術人員給大家分析一下引起抖動的原因有哪些？
   
1、山東超低裝載機液壓系統采用轉向優先方式，轉向泵輸出的壓力油與工作泵輸出的壓力油合流后向工作裝置供油。工作泵只有在工作裝置動作時才承受負荷，而轉向泵不但在工作裝置動作時承受負荷，轉向時也承受負荷，因此轉向泵工作時間相對較長、磨損較大。
Shandong ultra-low-loader hydraulic steering system uses priority mode, steering pump output pressure oil pump output pressure of the working oil to the working device after merging oil. Pump only work when the work equipment to

withstand the load operation, while steering pump not only withstand the load at work means action, but also bear the load when steering, steering pump and therefore a relatively long time, wear large.
   
2、山東裝載機在優先閥閥體、閥芯、調壓彈簧和壓力油的共同作用下，EF口開啟與閉合按照一定頻率相互變換，便發生一定頻率的振動。由于該振動與儀表臺、駕駛室的固有振動頻率接近，導致儀表臺、駕駛室發生共振。
Shandong loaders under the joint action priority valve body, valve, pressure regulator spring and oil, EF mouth opening and closing transform each other according to a certain frequency, the vibration of a certain frequency will occur.Since the vibration and dashboard, close to the natural frequency of the cab, resulting in the instrument panel, cabin resonance.
   
3、山東裝載機http://m.lcsqtax.cn/如果在發生抖動時轉動轉向盤，優先閥的EF口就會關閉，轉向泵就不會通過優先閥向工作裝置液壓系統提供脈沖油液，裝載機也就不會發生抖動現象。 
If you turn the steering wheel loaders Shandong in the event of a shake, the EF port priority valve closes, it will not provide a pulse steering pump oil to the hydraulic system via priority valve, loaders will not happen jitter.
