自动混凝土搅拌机出现气压不足问题如何处理？

1.检查混凝土搅拌机的液压泵是否可以输出液压油。对于新的液压泵，液压油可能不会流出，并且泵体中可能会出现铸件缺陷（收缩，沙孔等）。由于吸油腔和液压腔是连通的，液压容量将耗尽，请尽早更换泵体。如果不是新的液压泵，并且没有液压输出，则泵转向可能不正确，零件严重磨损或损坏，应及时更换。

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.如果自动混凝土搅拌机的液压泵有油输出，请检查溢流阀是否正常工作。如果出现异常，压力油回路的阀可能会因灰尘等原因而被卡住，并且可能处于回油位置，从而导致压力油回路与溢流管线之间发生短路。接头松动或液压回路中有接头。一些阀门泄漏严重，或者液压缸和液压马达上的密封件损坏，导致严重泄漏。要卸下它，请拆卸并清洗适用的阀门，检查密封间隙和各种密封装置的尺寸，如果密封装置损坏，请更换密封装置。

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.如果混凝土搅拌机的液压泵的输出流量随着压力的增加而显着下降，并且压力未达到指定值，这是由于液压泵磨损后的间隙增加所致。拆卸方法是测量液压泵的容积效率，以确定泵是否仍然可以使用。严重磨损的零件应予以修理或更换。

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.自动混凝土搅拌机的液压系统可建立常压，某些管道或液压缸（或液压马达）无压力。这可能是由于管道，小孔或节流阀，方向控制阀和其他组件的堵塞引起的。此时，必须逐步检查油的压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.

混凝土搅拌机气压不足处理就是这样，希望对你有帮助。

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