自上料搅拌车液压系统过热可能是以下一种或多种原因造成：当油中进入空气或水分，液压泵把油液转变为压力时，空气和水分就会因热量增加导致过热;液压系统内的油平面过高，油液强烈搅动，而引起过热;质量较差的油可能变稀，使外来物质漂浮或与水有亲合力，这样也会引起过热;工作时超负荷工作，也会产生热量;回油阀调整不当或未及时更换已损坏零件，也会产生热量。自上料搅拌车
The overheating of the hydraulic system of the self loading mixer truck may be caused by one or more of the following reasons: when air or water enters the oil and the hydraulic pump converts the oil into pressure, the air and water will overheat due to the increase of heat; The oil level in the hydraulic system is too high, and the oil is stirred strongly, causing overheating; Poor quality oil may become thinner, causing foreign substances to float or have affinity with water, which will also cause overheating; Working overload will also generate heat; Improper adjustment of oil return valve or failure to replace damaged parts in time will also generate heat.

自上料搅拌车液压系统过热是因为什么？
What is the reason why the hydraulic system of the self loading mixer is overheated?
当空气进入油中除引起过热外，如果被压缩的体积大约有20%是属于被溶的空气，则压力下降时便会形成泡沫。而工作液压缸在减压回油时，带泡沫的油液就会形成“海绵”的性质。此外，油中含有许多泡沫会增加总体积，将造成油箱或储油器的溢油现象。自上料搅拌车
When air enters the oil, in addition to causing overheating, if about 20% of the compressed volume belongs to dissolved air, foam will form when the pressure drops. When the working hydraulic cylinder depressurizes and returns oil, the oil with foam will form a "sponge" nature. In addition, the oil contains many foam, which will increase the total volume and cause the oil tank or oil reservoir to overflow. Self loading mixer
含有空气的工作油，在传递动力时会产生急跳的痉挛现象，含有空气的工作油，还会造成液压泵发生气穴的危险，由此而产生更大的吸力，会把更多的空气连同其他杂质都吸入系统内。因油中进入空气而产生过热，空气进入的同时也会带进灰尘，这些情况会使油很快变质。
The working oil containing air will produce jerky spasm when transmitting power. The working oil containing air will also cause the danger of cavitation of the hydraulic pump, resulting in greater suction, which will suck more air and other impurities into the system. Overheating is caused by air entering the oil, and dust will also be brought into the air at the same time. These conditions will make the oil deteriorate quickly.
