混凝土搅拌车液压系统中压力不足或无压力的原因

所属分类：常见问题发布时间：2022-04-15 来源：http://www.sqjituan.cn/ 浏览量：0

液压系统对于混凝土搅拌车的运行状况较为重要，在混凝土搅拌车的操作过程中，如果液压系统出现故障，则搅拌车的操作功能将大大降低。接下来讲下混凝土搅拌车液压系统中压力不足或无压力的原因，如果混凝土搅拌车显示液压系统中压力不足或根本没有压力，我们可以根据以下方面进行故障排除：

The hydraulic system is more important for the operation of the concrete mixer. In the operation process of the concrete mixer, if the hydraulic system fails, the operation function of the mixer will be greatly reduced. Next, let's talk about the reasons for insufficient or no pressure in the hydraulic system of the concrete mixer. If the concrete mixer shows insufficient or no pressure in the hydraulic system, we can troubleshoot according to the following aspects:

1，检查液压泵是否可以输出液压油。如果是没有液压油输出的新型液压泵，则可能是泵体存在铸造缺陷（收缩，沙眼等），因此吸油腔和液压腔已连接，并且油压丢失，应及时更换制造商。如果不是新的液压泵，并且没有液压油输出，则可能无法正确操纵泵，并且零件可能会严重磨损或损坏。及时更换它们。

1. Check whether the hydraulic pump can output hydraulic oil. If it is a new type of hydraulic pump without hydraulic oil output, the pump body may have casting defects (shrinkage, trachoma, 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 the parts may be severely worn or damaged. Replace them in time.

2，如果液压泵有油输出，请检查阀是否正常工作。如果异常，则可能是压力油回路中的阀因其他原因被污染或阻塞，并且处于回油位置，导致压力油回路与溢流回路短路，或者管接头可能松动或受压。油路中的某些阀泄漏严重，或者液压缸和液压马达的密封件损坏，导致严重泄漏。

2. If the hydraulic pump has oil output, please check whether the safety valve works normally. If it is abnormal, the valve in the pressure oil circuit may be contaminated or blocked for other reasons and 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 the hydraulic cylinder and hydraulic motor are damaged, resulting in serious leakage.

3，如果液压泵的输出流量随压力的增加而显着下降，而压力未达到规定值，则是由于液压泵磨损后间隙的增加而引起的。

3. If the output flow of the hydraulic pump decreases significantly 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.

4，如果混凝土搅拌车的整个液压系统能够建立正常压力，并且某些管线或液压缸（或液压马达）中没有压力，则可能是由于管线，小孔或节流阀，方向阀等引起的。封锁此时，应逐一检查压力和油的存在，找出原因并进行清理。

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 cause and clean it up.
