We should all know that the hydraulic system is very important for the operation of the vehicle. In the operation process of concrete mixer, if the hydraulic system fails, the operation function of the mixer will be greatly reduced. As long as the owner's friends understand the hydraulic system fault and timely troubleshooting, they can make the mixer normal. Today, Xiaobian collected the causes of insufficient or no pressure in the hydraulic system of automatic concrete mixer, and made diagnosis and elimination for the owners to learn.

显现液压体系中压力缺乏或底子不压力，咱们可以或许或许按照以下方面停止毛病解除：
If the concrete mixer shows that the pressure in the hydraulic system is insufficient or there is no pressure at all, we can carry out troubleshooting according to the following aspects:
1.查抄液压泵是不是是是可以或许或许输入液压油。若是是不液压油输入的新型液压泵，则可以或许或许是泵体存在锻造缺点（缩短，沙眼等），是以吸油腔和液压腔已毗连，并且油压丧失，应实时改换制作商。若是不是是是新的液压泵，并且不液压油输入，则可以或许或许没法准确支配泵，并且整机可以或许或许会严峻磨损或破坏。实时改换它们。
1. Check whether the hydraulic pump can output hydraulic oil. If it is a new type of hydraulic pump without hydraulic oil output, it may be that the pump body has casting defects (shrinkage, sand hole, etc.), so the oil suction chamber and hydraulic chamber have been connected, and the oil pressure is lost, the manufacturer should be replaced in time. If it is not a new hydraulic pump and there is no hydraulic oil output, the pump may not be operated correctly and parts may be severely worn or damaged. WordStr them in time.
2.若是液压泵有油输入，请查抄宁静阀是不是是是一般任务。若是很是，则可以或许或许是压力油回路中的阀因其余缘由被净化或梗阻，并且处于回油地位，致使压力油回路与溢流回路短路，或管讨论可以或许或许松动或受压。油路中的某些阀泄露严峻，或液压缸和液压马达的密封件破坏，致使严峻泄露。
2. If the hydraulic pump has oil output, please check whether the safety valve works normally. If it is abnormal, it may be that the valve in the pressure oil circuit is polluted or blocked due to other reasons and is in the oil return position, resulting in a short circuit between the pressure oil circuit and the overflow circuit, or the pipe joint may be loose or pressurized. Some valves in the oil circuit leak seriously, or the seals of hydraulic cylinder and hydraulic motor are damaged, resulting in serious leakage.
洁净方式：翻开相干阀门停止洁净，查抄密封空隙和各类密封装备的巨细。破坏的密封装备应予以改换。
Cleaning method: open the relevant valve for cleaning, check the seal clearance and the size of various sealing equipment. Damaged sealing equipment should be replaced.
3.若是液压泵的输入流量随压力的增添而光鲜明显降落，而压力未到达划定值，则是因为液压泵磨损后空隙的增添而引发的。
3. If the output flow of the hydraulic pump decreases significantly with the increase of the pressure, but the pressure does not reach the specified value, it is caused by the increase of the clearance after the wear of the hydraulic pump.
打扫方式：肯定液压泵的容积功率，以确认泵是不是是是可以或许或许持续利用。严峻磨损的整机应补缀或改换。
Cleaning method: determine the volume power of the hydraulic pump to confirm whether the pump can be used continuously. Seriously worn parts should be repaired or replaced.
4.若是打鱼注册送分
的全部液压体系可以或许或许成立一般压力，并且某些管线或液压缸（或液压马达）中不压力，则可以或许或许是因为管线，小孔或节省阀，标的目的阀等引发的。封闭此时，应一一查抄压力和油的存在，找出缘由并停止清算。
4. If the whole hydraulic system of the concrete mixer can establish normal pressure, and there is no pressure in some pipelines or hydraulic cylinders (or hydraulic motors), it may be caused by pipelines, small holes or throttle valves, directional valves, etc. At this time, check the existence of pressure and oil one by one, find out the causes and clean them up.
