自動混凝土攪拌機出現氣壓不足問題如何處理？

1.檢查混凝土攪拌機的液壓泵是否可以輸出液壓油。對于新的液壓泵，液壓油可能不會流出，并且泵體中可能會出現鑄件缺陷（收縮，沙孔等）。由于吸油腔和液壓腔是連通的，液壓容量將耗盡，請盡早更換泵體。如果不是新的液壓泵，并且沒有液壓輸出，則泵轉向可能不正確，零件嚴重磨損或損壞，應及時更換。

1. Check whether the hydraulic pump of automatic concrete mixer can output hydraulic oil. For a new hydraulic pump, the hydraulic oil may not flow out, and casting defects (shrinkage, sand holes, etc.) may appear in the pump body. Since the oil suction chamber and the hydraulic chamber are connected, the hydraulic capacity will be exhausted. Please replace the pump body as soon as possible. If it is not a new hydraulic pump and there is no hydraulic output, the steering of the pump may be incorrect and the parts may be seriously worn or damaged, so it should be replaced in time.

2.如果自動混凝土攪拌機的液壓泵有油輸出，請檢查溢流閥是否正常工作。如果出現異常，壓力油回路的閥可能會因灰塵等原因而被卡住，并且可能處于回油位置，從而導致壓力油回路與溢流管線之間發生短路。接頭松動或液壓回路中有接頭。一些閥門泄漏嚴重，或者液壓缸和液壓馬達上的密封件損壞，導致嚴重泄漏。要卸下它，請拆卸并清洗適用的閥門，檢查密封間隙和各種密封裝置的尺寸，如果密封裝置損壞，請更換密封裝置。

2. If the hydraulic pump of concrete mixer has oil output, please check whether the relief valve works normally. If there is any abnormality, the valve of the pressure oil circuit may be stuck due to dust and other reasons, and may be in the oil return position, resulting in a short circuit between the pressure oil circuit and the overflow pipeline. Loose connector or connector in hydraulic circuit. Some valves have serious leakage, or the seals on the hydraulic cylinder and hydraulic motor are damaged, leading to serious leakage. To remove it, please remove and clean the applicable valve, check the sealing clearance and dimensions of various sealing devices, if the sealing device is damaged, please replace the sealing device.

3.如果混凝土攪拌機的液壓泵的輸出流量隨著壓力的增加而顯著下降，并且壓力未達到指定值，這是由于液壓泵磨損后的間隙增加所致。拆卸方法是測量液壓泵的容積效率，以確定泵是否仍然可以使用。嚴重磨損的零件應予以修理或更換。

3. If the output flow of the hydraulic pump of the concrete mixer 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 gap after the hydraulic pump is worn. The disassembly method is to measure the volumetric efficiency of the hydraulic pump to determine whether the pump can still be used. Severely worn parts should be repaired or replaced.

4.自動混凝土攪拌機的液壓系統可建立常壓，某些管道或液壓缸（或液壓馬達）無壓力。這可能是由于管道，小孔或節流閥，方向控制閥和其他組件的堵塞引起的。此時，必須逐步檢查油的壓力和油的存在以找出原因并。

4. The hydraulic system of automatic concrete mixer can establish normal pressure, and some pipes or hydraulic cylinders (or hydraulic motors) have no pressure. This may be caused by blockage of pipes, orifices or throttle valves, directional control valves and other components. At this time, the pressure of oil and the existence of oil must be checked step by step to find out the cause and eliminate it.

混凝土攪拌機氣壓不足處理就是這樣，希望對你有幫助。

The concrete mixer air pressure insufficient processing is like this, hoped has the help to you.
