如何自动搅拌一体机液压压力表压力不足的问题，以及如何混凝土搅拌机液压系统的问题。当自动搅拌一体液压系统的气压不足或根本没有压力时，我们可以从以下几个方面进行调查。

How to solve the problem of insufficient pressure in the hydraulic pressure gauge of automatic mixing machine and how to solve the problem of hydraulic system of concrete mixer. When the air pressure of the automatic mixing integrated hydraulic system is insufficient or there is no pressure at all, we can investigate from the following aspects.

1. 检查自动搅拌一体液压泵是否能输出液压油。如果是新液压泵，没有液压油输出，则可能是泵体有铸造缺陷(缩孔、砂孔等)，使吸油腔与油压腔接触，油压能力损失，应及时找厂家更换。如果没有新的液压泵，没有液压油输出，则可能是泵转向错误，零件磨损或损坏，及时更换。

1. Check whether the automatic mixing 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.), which makes the oil suction chamber contact with the oil pressure chamber, resulting in the loss of oil pressure capacity. It should be replaced by the manufacturer in time. If there is no new hydraulic pump and no hydraulic oil output, it may be the pump steering error, parts wear or damage, timely replacement.

2. 自动搅拌一体液压泵出油时，检查溢流阀是否工作正常。如果不正常,它可能是一个阀的压力油线灰尘或其他原因,在回油位置,导致短路之间的压力油线和溢出电路,也可以管接头松动,或在压力线一些油阀泄漏严重,或液压缸,液压马达密封损坏,严重的泄漏。方法是打开阀门进行清洗，检查密封间隙大小及各种密封装置，密封装置损坏应更换。

2. Check whether the relief valve works normally when the hydraulic pump of automatic mixing is discharging oil. If it is abnormal, it may be a valve pressure oil line dust or other reasons, in the oil return position, resulting in a short circuit between the pressure oil line and the overflow circuit, or loose pipe joints, or serious leakage of some oil valves in the pressure line, or the seal damage of hydraulic cylinder and hydraulic motor, serious leakage. The elimination method is to open the valve for cleaning, check the size of sealing clearance and various sealing devices, and replace the damaged sealing devices.

3.如果自动搅拌一体液压泵的输出流量随着压力的增大而明显减小，且压力未达到规定值，则是由于液压泵磨损后间隙增大引起的。方法是确定液压泵的容积效率，可以确定泵是否可以继续使用，对磨损严重的部件，应进行修理或更换。

3. If the output flow of the automatic mixing integrated hydraulic pump decreases obviously with the increase of pressure, and the pressure does not reach the specified value, it is caused by the increase of clearance after the hydraulic pump is worn. The elimination method is to determine the volumetric efficiency of the hydraulic pump, to determine whether the pump can continue to be used, and repair or replace the seriously worn parts.

4、自动搅拌一体的液压系统可建立正常压力，而有些管路或液压缸(或液压马达)无压力时，则可能由于管路、开孔或节流阀、换向阀等部件堵塞。这时应逐段检查油压和油液通过情况，找出原因，加以。

4. The hydraulic system of automatic mixing can establish normal pressure, but when some pipelines or hydraulic cylinders (or hydraulic motors) are not under pressure, they may be blocked by pipeline, opening or throttle valve, reversing valve and other parts. At this time, the oil pressure and oil passing through should be checked one by one to find out the causes and eliminate them.

以上是自动搅拌一体为大家介绍的自动搅拌一体压力不足的处理方法。如搅拌车内出现液压系统压力不足或根本没有压力时，可按上述方法检查，使混合器及时恢复正常状态。

The above is the automatic mixing one for everyone to introduce the automatic mixing one pressure insufficient processing method. If the hydraulic system pressure in the mixer truck is insufficient or there is no pressure at all, it can be checked and solved according to the above methods, so that the mixer can be restored to normal state in time.
