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 if the hydraulic pump of the automatic feeding mixer truck can output hydraulic oil. For new hydraulic pumps, hydraulic oil may not flow out and casting defects (shrinkage, sand holes, etc.) may appear in the pump body. Due to the connection between the suction chamber and the hydraulic chamber, the hydraulic capacity will be depleted. 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 direction may be incorrect, and the parts may be severely worn or damaged, which should be replaced in a timely manner
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。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。
If there is oil in the hydraulic pump of the automatic feeding mixer truck, please check if the overflow valve is working properly. If an abnormality occurs, the valve of the pressure oil circuit may be stuck due to dust and other reasons, and may be in the return position, resulting in a short circuit between the pressure oil circuit and the overflow pipeline. Loose connectors or connectors in the hydraulic circuit. Some valves may have severe leaks, perhaps due to damaged seals on hydraulic cylinders and motors. To remove it, please disassemble and clean the applicable valve, check the sealing gap and the dimensions of various sealing equipment. If the sealing equipment is damaged, please replace the sealing equipment.
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。
If the output flow rate 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 caused by the addition of gaps after the hydraulic pump is worn. The disassembly method is to measure the volumetric power of the hydraulic pump to determine if the pump is still usable. Severely worn parts should 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。
The hydraulic system of the automatic feeding mixer truck can establish normal pressure, and some pipelines or hydraulic cylinders (or hydraulic motors) do not have pressure. This may be caused by blockage of pipelines, small holes or throttle valves, directional control valves, and other components. At this moment, it is necessary to gradually check the presence of oil pressure and oil to identify the cause and eliminate it.
