装载机爆管可能是使用了劣质的液压管,更换液压管时一定要选择正规大品牌的产品。

The loader detonator may be the use of the inferior hydraulic pipe, the replacement of the hydraulic pipe must choose the regular large brand products.

装载机爆管可能是使用了劣质的液压管,更换液压管时一定要选择正规大品牌的产品。如果液压系统预设的压力过高会加大爆管的几率,方法是结合各种动作测试主泵产生的压力值,如果确认压力值偏大,可以将多路阀的压力适当调低一些。

The loader detonator may be the use of the inferior hydraulic pipe, the replacement of the hydraulic pipe must choose the regular large brand products. If the preset pressure of the hydraulic system is too high, it will increase the probability of bursting. The method is to test the pressure value produced by the main pump combined with various actions. If we confirm that the pressure value is too large, we can lower the pressure of the multi way valve appropriately.


如果装载机液压系统高温,也会影响液压元件的密封性,引发爆管泄露;另外高温还会使液压部件膨胀,导致阀芯、阀体卡死,形成局部高温导致爆管。如果在使用过程中添加配件店常见的68#液压油,会造成液压油性质不稳定,损坏元器件。高粘度的液压油流动性较差,会使液压系统局部产生较高的压力,易造成管路泄漏。

If the hydraulic system of the loader is at high temperature, it will also affect the sealing performance of the hydraulic components and cause the leakage of the bursting pipe. In addition, the high temperature will also cause the expansion of the hydraulic components, resulting in the valve core and the valve body stuck, causing the local high temperature to cause the tube burst. If the common 68# hydraulic oil is added to the accessories store in the process of use, it will cause the instability of the hydraulic oil properties and damage the components. The poor fluidity of high viscosity hydraulic oil will cause high pressure in the hydraulic system, and easily cause leakage of the pipeline.


如果装载机在作业时操作粗暴,巨大的冲击负荷会在液压系统中产生瞬时的冲击压力,冲击压力会导致高压油管接头与胶管的压合处过早失效漏油或爆管,大大缩短液压管的使用寿命。另外,粗暴的操作还会影响其他部件的耐久性,使机械故障频发。所以,平时操作动作一定要柔和,不做高强度、高危险性动作。

If the loader is rough in operation, the huge impact load will produce transient impact pressure in the hydraulic system. The impact pressure will lead to the premature failure of the high pressure tubing connection and the hose, premature leakage, or leakage, and greatly shorten the service life of the hydraulic pipe. In addition, the rough operation will also affect the durability of other components, so that the mechanical failure occurs frequently. Therefore, the usual operation must be soft, not high intensity, high dangerous action.


当作业工程中装载机发生了液压管爆管,由于爆管是液压管内存在较高的压力,为了避免液压油过多的流失,应先把铲斗落地,然后停机熄火,降低液压系统中的压力,减缓油液流失。如果施工场地条件所限,无法立即更换液压管时,可以采取一定了修复措施。当液压系统的压力在25-8.0MPa之间的橡胶软管破裂时,可采取粘补法:具体方法是将软管破裂处周围擦试干净;涂上“厌氧”胶、“环氧树脂”胶、“801”胶或“502”胶中的一种用胶布或布条缠绕涂胶处4-5层(每层都应涂上胶)即可起到暂时密封的作用。贵州直喷装载机小编今天就分享到这里了。

When a hydraulic tube exploded in a loader happened in operation engineering, because there was a higher pressure in the hydraulic pipe, and in order to avoid the excessive loss of hydraulic oil, the bucket should be landed first and then shut down and stalled, so as to reduce the pressure in the hydraulic system and slow down the oil loss. If the condition of the construction site is limited, the repair measures can be taken when the hydraulic pipe can not be replaced immediately. When the rubber hose between 25-8.0MPa hydraulic system pressure rupture, can take the sticking method: the specific method is ruptured hose around wipe clean; paint "anaerobic" glue ", epoxy resin glue, glue" 801 "or" 502 "glue in a cloth wrapped with tape or glue. The 4-5 layer (each layer should be coated with glue) can play the role of temporary sealing. The Guizhou direct jet loader has been shared here today.
