液壓系統(tǒng)管路配置不合理實例分析

某工廠生産的設備安裝升降臺液壓系統(tǒng)如下圖所示，用雙泵雙回路控制兩個頂升液壓油缸，實現(xiàn)雙缸同時動作或單缸動作。兩個同路對應的液壓元件規(guī)格相同，管路通徑相同。

1）存在問題。液壓泵l和2同時起動，溢流閥3和4壓力不穩(wěn)定，振動且産生噪聲。

2）問題分析。試驗表明，隻有一個泵起動單缸動作時，溢流閥調整的壓力穩(wěn)定，也沒有明顯的振動和噪聲。當雙泵同時起動，即兩個溢流閥同時工作時就出現(xiàn)上述故障。

根據(jù)分析可以看出，兩個溢流閥除了有一個共同的同油管路外，并沒有其他聯(lián)系。顯然，故障原因是由于共用同一個同油管路造成的。如果總回油管路仍按單獨回路的通徑設計和選取，則必使雙泵同時供油時溢流閥回油口背壓增高。

可見，雙泵同時工作時，總回油管路沿程阻力損失大約增大2倍(層流)或4倍（紊流），即溢流閥的回油口背壓增大2倍或4倍。

從溢流閥的結構可知，溢流閥的控制油道爲內洩，即溢流閥的糊前任力油進入閥內，經阻尼孔流進控制容腔（主閥上部彈簧腔）。當壓力升高克服先導閥的調壓彈簧力時，壓力油打開先導閥閥口，油流過閥口降壓后，經閥體內洩孔道流進溢流閥的同油腔，與主閥溢出的油流彙合，經回油管路一同流回油箱。因此，溢流閥的回油管路中油流的流動狀態(tài)直接影響溢流閥的調整壓力。倘若有壓力沖擊、背壓等流體波動直接作用在先導閥上，并與先導閥彈簧力方向一緻，則控制容腔中的油液壓力也隨之增高，并隨之出現(xiàn)沖擊與波動，導緻溢流閥調整的壓力不穩(wěn)定，并易激起振動和噪聲。

3）解決方法。

A.將兩個溢流閥的回油管路分別接回油箱，避免相互干擾。

B.將合流后的總回油管路通徑加大，并將兩個溢流閥均改爲外部洩漏型，即將經過先導閥閥口的油流與主閥回油腔隔開，單獨接回油箱。

此例液壓系統(tǒng)的工作原理沒有問題，但在實際使用中卻出現(xiàn)了故障。這說明，設計時，除了應正確地選擇元件組成系統(tǒng)外，還應該合理地設計配置管路。
