搅动车液压件的一些主要不利因素

作者:http://www.zkzsljbc.com 时间:2022-06-17

全自动搅拌车液压系统的致病因素:污染,过热,以及进入空气。三大不利因素之间存在密切联系,任何一项不利因素的出现都会导致另一项或多项问题的出现。结果表明,液压系统中95%的“致病性”因素,都是由这三个不利因素引起的。
The pathogenic factors of the hydraulic system of the automatic mixer: pollution, overheating, and entering air. There is a close relationship among the three major adverse factors, and the occurrence of any one adverse factor will lead to the emergence of another or more problems. The results show that 95% of the "pathogenic" factors in the hydraulic system are caused by these three adverse factors.
如液压零件的制造没有问题,则造成损坏的原因一般是维修不当,操作不当的原因一般较少。对搅拌车的工作环境认识不足是主要原因。若了解一些常识原理,了解引起故障的三大不利因素,就能保证长期工作状态良好。
If there is no problem with the manufacture of hydraulic parts, the damage is generally caused by improper maintenance, and the reasons for improper operation are generally less. Lack of understanding of the working environment of the mixer truck is the main reason. If you know some common sense principles and understand the three adverse factors that cause faults, you can ensure good long-term working conditions.
搅拌车工作油液进入异物变质油液中的异物,其来源有灰、砂、土等:
The working oil of the mixer truck enters the foreign matters in the deteriorated oil, and the sources include ash, sand, soil, etc
液压部件外部未清洁,未清除杂质进料带进系统,或密封圈损坏进入系统;内部清洁不干净,油箱或零件内易留有少量杂质;进料容器、器具应清洁;油液储存不当,油液加进去之前不清洁或已经变质;已变质的油会损坏零件。金属分子被破坏后悬浮在油中。  异物对工件有损伤和腐蚀作用,特别是对精加工工件而言,异物对皮管的内壁、油封圈和填充物有损伤,从而导致液压系统失效。
The outside of hydraulic components is not cleaned, impurities are not removed, and the feed is brought into the system, or the sealing ring is damaged and enters the system; The interior is not clean, and a small amount of impurities are easily left in the oil tank or parts; Feed containers and appliances shall be clean; Improper oil storage, unclean or deteriorated before adding oil; Deteriorated oil can damage parts. Metal molecules are broken and suspended in oil. The foreign matters may damage and corrode the workpiece, especially for the finished workpiece. The foreign matters may damage the inner wall, oil seal ring and filler of the leather pipe, resulting in the failure of the hydraulic system.

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。
The overheating of the hydraulic system 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 agitates strongly, causing overheating; Oil with poor quality may become thin, causing foreign substances to float or have affinity with water, which may 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.
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。
When air enters the oil, in addition to causing overheating, if about 20% of the compressed volume belongs to dissolved air, foam will be formed when the pressure drops. When the working hydraulic cylinder depressurizes and returns oil, the oil with foam will form a "sponge" property. In addition, the oil contains a lot of foam, which will increase the total volume and cause the oil tank or oil reservoir to overflow.
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 risk of cavitation of the hydraulic pump, resulting in greater suction, which will suck more air and other impurities into the system. The oil will overheat due to the air entering the oil, and the air will also bring in dust at the same time, which will quickly deteriorate the oil.
