装料，卸料，搅拌罐的转动等都离不开液压系统，所以液压系统对于自动搅拌车是非常重要的，很多搅拌车的车主都会遇到这样的问题，那就是液压系统的压力不足，这让车主们很是着急，那这到底是为什么呢？

Loading, unloading, and the rotation of the mixing tank are all inseparable from the hydraulic system, so the hydraulic system is very important for automatic mixer trucks. Many mixer truck owners will encounter this problem, that is, the pressure of the hydraulic system is insufficient, which makes the owners very worried. Why on earth is this?

1.查看自动上料搅拌车的液压泵是否能够输出液压油。对于新的液压泵，液压油或许不会流出，并且泵体中或许会呈现铸件缺陷（收缩，沙孔等）。由于吸入室和液压室已衔接，液压容量将耗尽，请尽快替换泵体。假如不是新的液压泵且没有液压输出，则泵转向或许不正确，零件严峻磨损或损坏，应及时替换

1. Check whether the hydraulic pump of the automatic feeding mixer can output hydraulic oil. For new hydraulic pumps, the hydraulic oil may not flow out, and casting defects (shrinkage, sand holes, etc.) may appear in the pump body. As the suction chamber and 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 pump steering may be incorrect, and the parts are severely worn or damaged, so they should be replaced in time

2.假如自动上料搅拌车的液压泵中有油，请查看溢流阀是否正常作业。假如产生异常，压力油回路的阀或许由于尘埃和其他原因而被卡住，并且有可能处于回油位置，然后导致压力油回路与溢流管线之间产生短路。

2. If there is oil in the hydraulic pump of the automatic feeding mixer, please check whether the overflow valve operates normally. In case of 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, which may cause a short circuit between the pressure oil circuit and the overflow pipeline.

接头松动或液压回路中有接头。一些阀严峻走漏，或许液压缸和液压马达上的密封件损坏，导致严峻走漏。要卸下它，请拆卸并清洗适用的阀门，查看密封空隙和各种密封设备的尺寸，假如密封设备损坏，请替换密封设备。

Loose connectors or connectors in the hydraulic circuit. Some valves leak severely. Perhaps the seals on the hydraulic cylinder and hydraulic motor are damaged, resulting in severe leakage. To remove it, disassemble and clean the applicable valve, check the sealing clearance and dimensions of various sealing devices, and replace the sealing device if it is damaged.

3.假如跟着压力的添加，移动式自动进料混合器的液压泵的输出流量明显下降，并且压力未达到指定值，这是由于液压泵磨损后的空隙添加所造成的。拆卸方法是丈量液压泵的容积功率，以确定泵是否仍然可用。严峻磨损的零件应修补或替换。

3. If the output flow of the hydraulic pump of the mobile automatic feed mixer decreases significantly with the addition of pressure, and the pressure does not reach the specified value, this is due to the gap addition after the wear of the hydraulic pump. The removal method is to measure the volume power of the hydraulic pump to determine whether the pump is still available. Parts severely worn shall be repaired or replaced.

4.自动上料搅拌车的液压体系能够树立常压，某些管道或液压缸（或液压马达）没有压力。这或许是由于管道，小孔或节流阀，方向控制阀和其他组件的阻塞引起的。此刻，必须逐渐查看油压和油的存在，以找出原因并消除。

4. The hydraulic system of the automatic feeding 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 throttles, directional control valves and other components. At this moment, the existence of oil pressure and oil must be checked gradually to find out the cause and eliminate it.
