              混凝土攪拌車系統壓力不足怎么解決?

              所屬分類:公司新聞 發布時間:2020-12-30 來源:http://www.ikpipi.com 瀏覽量:18

              攪拌車使用過程中,如果液壓系統出現故障會使攪拌車的工作性能大大降低,車主朋友們只有了解了液壓系統的故障原因并及時排出解決故障才能使攪拌車恢復正常,今天收集了有關攪拌車液壓系統壓力不足或完全無壓力的原因、診斷和排除,供車主朋友們參考學習。
              In the process of using the mixer, if the hydraulic system fails, the working performance of the mixer will be greatly reduced. Only by understanding the causes of the failure of the hydraulic system and eliminating it in time, can the mixer return to normal. Today, we collected the causes, diagnosis and troubleshooting of the insufficient or no pressure of the hydraulic system of the mixer, for the reference of the owners Learning.
              如果混凝土攪拌車出現液壓系統壓力不足或完全無壓力時,我們可以根據以下幾個方面依次進行排查:
              If there is insufficient or no pressure in the hydraulic system of the concrete mixer, we can check it in turn according to the following aspects:
              一、查看液壓泵是否能輸出液壓油。如果是新的液壓泵,無液壓油輸出,可能是泵體有鑄造缺陷(縮孔、砂眼等),使吸油腔和壓油腔相通,失去壓油能力,應及時找廠家更換。若不是新的液壓泵,無液壓油輸出,則可能是泵的轉向不對,零件磨損嚴重或損壞,及時更換。
              1、 Check whether the hydraulic pump can output hydraulic oil. If it is a new hydraulic pump and there is no hydraulic oil output, it may be that the pump body has casting defects (shrinkage cavity, sand hole, etc.), so that the oil suction cavity is connected with the oil pressure cavity and the oil pressure capacity is lost. It should be replaced by the manufacturer in time. If it is not a new hydraulic pump and there is no hydraulic oil output, it may be that the steering of the pump is not right and the parts are seriously worn or damaged, so it should be replaced in time.

              二、若液壓泵有油液輸出,查看溢流閥工作是否正常。若不正常,則可能是壓力油路中的某個閥有污物或其他原因卡住,處于回油位置,致使壓力油路與溢流回路短路,也可能是管接頭松脫,或處于壓力油路中的某些閥泄漏嚴重,或液壓缸、液壓馬達的密封損壞,嚴重泄漏。
              2、 If the hydraulic pump has oil output, check whether the relief valve works normally. If it is abnormal, it may be that one of the valves in the pressure oil circuit is stuck in the oil return position due to dirt or other reasons, resulting in a short circuit between the pressure oil circuit and the overflow circuit. It may also be that the pipe joint is loose, or some valves in the pressure oil circuit are seriously leaking, or the seals of the hydraulic cylinder and hydraulic Mada are damaged, resulting in serious leakage.
              排除方法:拆開有關閥進行清洗,檢查密封間隙的大小及各種密封裝置,密封裝置損壞應更換。
              Troubleshooting: disassemble the relevant valve for cleaning, check the size of the sealing gap and various sealing devices, and replace the damaged sealing device.
              三、若液壓泵輸出流量隨壓力升高而顯著減小,且壓力達不到規定值,則是由于液壓泵磨損后間隙增大所致。
              3、 If the output flow of the hydraulic pump decreases significantly with the increase of the pressure, and the pressure does not reach the specified value, it is due to the increase of the clearance after the wear of the hydraulic pump.
              排除方法:測定液壓泵的容積效率,即可確定該泵是否能繼續使用,對磨損嚴重的零件,應進行修配或更換。
              Elimination method: determine the volume efficiency of the hydraulic pump to determine whether the pump can continue to use, and repair or replace the worn parts.
              四、若整個液壓系統能建立正常壓力,而某些管路或液壓缸(或液壓馬達)中無壓力,則可能是由于管路、小孔或節流閥、換向閥等部位堵塞。此時,應逐段檢查壓力和有無油液通過,找出原因,加以排除。
              4、 If the whole hydraulic system can establish normal pressure, but there is no pressure in some pipelines or hydraulic cylinders (or hydraulic motors), it may be due to blockage of pipelines, orifices, throttle valves, directional valves, etc. At this time, the pressure and oil flow should be checked step by step to find out the cause and eliminate it.
