          斗山220-7挖掘機常見的股章有哪些?

          日期:2023-09-25   來源:http://www.dieuhoamulti.com/
          斗山220-7挖掘機干活兒突然冒出整車無姿勢狀況,在前不久機主剛清理了液壓油濾芯,拆換了齒輪油和過濾芯后設備工作中不斷出現姿勢斷斷續續難題,不確定性何時就犯問題。
          The Doushan 220-7 excavator suddenly appeared in a state of no posture while working. Recently, the owner of the excavator had just cleaned the hydraulic oil filter element, replaced the gear oil and filter element, and the equipment continued to encounter intermittent posture problems during operation. It is uncertain when the problem will occur.
          到之后設備還多了一個常見故障,旋轉也不可以轉了。姿勢慢再再加沒法旋轉,設備一瞬間趴窩只有停產檢修。
          After that, there was another common malfunction with the device, which prevented it from rotating. The posture is slow and unable to rotate, causing the equipment to collapse in an instant and have to be shut down for maintenance.
          常見故障點剖析
          Analysis of common fault points
          1、主導鎖電源開關虛連,造成主導繼電器供電系統時斷時續。
          1. The virtual connection of the main lock power switch causes the main relay power supply system to be intermittent.

          2、主導電磁閥線圈超溫造成磁性降低,從而造成主導工作壓力油間歇性通斷。
          2. The overheating of the main solenoid valve coil causes a decrease in magnetism, resulting in intermittent on-off of the main working pressure oil.
          3、主導繼電器閥心卡屏,打開異常。
          3. The main relay valve core is stuck on the screen, and the opening is abnormal.
          4、調壓閥卡屏調壓閥過濾網阻塞,造成主導工作壓力低。
          4. The filter screen of the pressure regulating valve is blocked, causing the main working pressure to be low.
          5、LS-EPC繼電器卡屏工作中出現異常。
          5. Abnormal operation of LS-EPC relay screen.
          6、旋轉姿勢出現異常猜疑和旋轉鎖住繼電器相關。
          6. Suspicion of abnormal rotation posture and related rotation locking relay.
          常見故障清除
          Clearing common faults
          1、到當場實際操作重現挖掘機整車姿勢,挖機整個設備速度比較慢,試了一會并沒有試出無姿勢,旋轉電機不可以旋轉。檢測設備主導工作壓力,發覺主導工作壓力不穩定而且工作壓力值還稍低。開啟汽車油箱,發覺齒輪油又一些臟了,過濾芯上也有殘渣,殘渣相近碎紙。
          1. On the spot, the actual operation reproduced the posture of the excavator as a whole. The speed of the excavator's entire equipment was relatively slow, and after trying for a while, no posture was found. The rotating motor cannot rotate. Detect the dominant working pressure of the equipment and find that the dominant working pressure is unstable and the working pressure value is slightly low. When I opened the car fuel tank, I found that the gear oil was dirty again, and there was residue on the filter element, similar to shredded paper.
          2、因為主導工作壓力不穩定,拆下來自調壓閥,拆卸后清理自調壓閥燃油管和過濾網,消除碎紙殘渣。清理主導繼電器閥心,確保閥心在油路板里無卡滯。
          2. Due to unstable working pressure, remove the self regulating valve, clean the fuel pipe and filter screen of the self regulating valve after disassembly, and eliminate paper debris. Clean the main relay valve core and ensure that the valve core is not stuck in the oil circuit board.
          3、清理自調壓閥以后,主導工作壓力平穩一切正常。但姿勢還是一些慢,依據工作經驗拆卸清理LS-EPC繼電器,重裝以后,歷經檢測,挖掘機姿勢很慢狀況消退。
          3. After cleaning the self regulating valve, the main working pressure is stable and everything is normal. But the posture is still a bit slow. Based on work experience, the LS-EPC relay was disassembled and cleaned. After reinstallation, after testing, the excavator posture was slow and the condition subsided.
          4、斷掉旋轉電機主閥上排簫的先軟管,實際操作旋轉姿勢,旋轉排簫先軟管并沒有壓力油造成,這時猜疑旋轉鎖住繼電器和閥心存有常見故障,歷經查驗旋轉鎖住繼電器供電系統狀況一切正常,因此拆卸閥心,發覺閥心也是被殘渣卡死,清理后再次拼裝,試運行旋轉電機工作中一切正常。
          4. Disconnect the hose of the main valve of the rotating motor for the flute. In actual operation, there is no pressure oil causing the hose to rotate. At this time, it is suspected that there is a common fault with the rotating lock relay and valve core. After checking the power supply system of the rotating lock relay, everything is normal. Therefore, after disassembling the valve core, it is found that the valve core is also stuck by debris. After cleaning, it is reassembled and the rotating motor is running normally.
