搅拌机一般用来给建筑工地运送混凝土的，现在的房产业很是火热，因此建筑工地上就忙的不可开交，自上料搅拌机也是马不停蹄，自上料搅拌机上液压系统用的是比较频繁的，很多自上料搅拌机会出现液压系统温度过高的现象？遇到这样的问题该怎么办呢？我们要知道是什么原因造成的，才能从根源上问题。

Mixers are generally used to deliver concrete to construction sites. Now the real estate industry is very hot, so the construction sites are busy. Self feeding mixers are also nonstop. The self feeding mixers are frequently used in the hydraulic system. Many self feeding mixers have the phenomenon of too high temperature in the hydraulic system? How to deal with such a problem? First of all, we need to know what causes it, so as to solve the problem from the root.

自上料搅拌机液压系统温度过高的原因：

Causes of high temperature in hydraulic system of self feeding mixer:

1. 液压系统泄漏严重，如果溢流阀调定压力过高，运动零件磨损过大就会使密封间隙加大，密封装置损坏，油液粘度过低等等，都会引起泄漏增加，找出故障根源就可以问题了。

1. The leakage of the hydraulic system is serious. If the set pressure of the relief valve is too high, the wear of the moving parts is too large, the sealing gap will be increased, the sealing device will be damaged, the viscosity of the oil is too low, etc., which will cause the leakage to increase. Finding out the root cause of the fault can solve the problem.

2. 液压系统散热比较差，比如油箱散热面积不足，油箱油面高度过低，这就使得油液循环过快，冷却水供应不足或风扇失灵，环境温度较高等原因，这些都会导致系统散热不良的。

2. The heat dissipation of the hydraulic system is relatively poor, such as the insufficient heat dissipation area of the oil tank, the low oil level of the oil tank, which makes the oil circulation too fast, the insufficient supply of cooling water or the failure of the fan, and the high ambient temperature, which will lead to poor heat dissipation of the system.

3. 油品的粘度过大，也会引起液压损失过大的。

3. If the viscosity of oil is too high, the hydraulic loss will be too large.

4. 液压系统卸荷回路工作不良，当搅拌机系统卸荷回路工作不良或没有卸荷回路，是搅拌机系统不需要压力时，而油液仍在溢流阀所调定的工作压力下溢回油箱，或在卸荷压力较高的情况下流回油路，此时应认真检查系统卸荷回路的工作是否正常，如果卸荷油道被脏物堵塞，或电气系统故障，引起卸荷作用的电磁阀不能工作，应及时采取措施，予以排除。

four The unloading circuit of the hydraulic system is not working well. When the unloading circuit of the mixer system is not working well or there is no unloading circuit, the oil still overflows back to the oil tank under the working pressure set by the relief valve when the mixer system does not need pressure, or flows back to the oil circuit when the unloading pressure is high. At this time, it is necessary to carefully check whether the unloading circuit of the system works normally. If the unloading oil passage is dirty If the electromagnetic valve can't work due to the blockage or electrical system fault, measures should be taken in time to eliminate it.

5. 如果以上这些故障排除后，仍然存在液压系统温度过高的问题，就有可能由于直接影响油温升高的调速方法、系统压力、液压缸及泵和马达的效率、各类阀的额定流量、管道的直径、油箱的容积及卸荷方式等问题，在液压中处理不当所造成的，应结合实际，具体分析，才能得出正确的结论。无论自上料搅拌机出现什么样的故障，一定要冷静，先找出故障的根源，这样才能快速的问题！

five If the above faults are eliminated, there is still the problem of too high temperature in the hydraulic system, which may be caused by improper handling in the hydraulic system, such as speed regulation method, system pressure, efficiency of hydraulic cylinder, pump and motor, rated flow of various valves, diameter of pipeline, volume of oil tank and unloading mode, which directly affect the oil temperature rise Analysis, in order to draw the correct conclusion. No matter what kind of fault from the feeding mixer, we must be calm, first find out the root of the fault, so as to quickly solve the problem!
