加长臂挖掘机夏季“三高”的预防方法

日期:2022-05-06   来源:http://www.dybocheng.com
  夏季来临,温度持续升高,给加长臂挖掘机带来的影响还是存在的,比如说“三高”,这是挖掘机夏日施工的通病,是导致故障停机的主要因素。那么加长臂挖掘机夏季“三高”的预防方法有什么呢?
  With the advent of summer, the temperature continues to rise, the impact on the extended arm excavator still exists, such as "three high", which is the common fault of excavator construction in summer, and is the main factor leading to failure and shutdown. So what are the prevention methods of the "three heights" of the extended arm excavator in summer?
  水箱温度过高俗称“开锅”。“开锅”影响发动机正常散热,继而引起发动机内零件的高温膨胀变形,例如活塞、活塞环受热膨胀卡死,同时高温加剧机油氧化,加快运动零件的磨损。其实在不破坏美观的前提下,正确使用防冻液就能有效避免开锅,防冻液的防锈、防腐蚀功能还能减缓整个冷却系统的老化,防水垢功能可防止水垢堵塞循环管道。
  The high temperature of the water tank is commonly known as "boiling pot". "Boiling pot" affects the normal heat dissipation of the engine, and then causes the high-temperature expansion deformation of parts in the engine, such as the piston and piston ring, which are heated and expanded and stuck, and the high temperature increases the oxidation of oil and speeds up the wear of moving parts. In fact, under the premise of not destroying the beauty, the correct use of antifreeze can effectively avoid boiling, antifreeze rust and corrosion function can also slow down the aging of the whole cooling system, anti-scale function can prevent scale blocking circulation pipeline.
  液压油温度过高时,油液的黏度、润滑性和耐磨性将明显下降,不仅会导致泄漏增加,各滑动部位的油膜也将被破坏,使液压元件的磨损加剧,因此夏天应选择黏度略高的液压油。当液压油温度持续增加时,各液压元件依照不同系数膨胀,也可能发生卡死故障,到时停机检修在所难免。预防液压油高温全凭日常检查保养。
  When the temperature of hydraulic oil is too high, the viscosity, lubricity and wear resistance of the oil will decrease significantly, which will not only lead to an increase in leakage, but also destroy the oil film of the sliding parts, aggravating the wear of hydraulic components. Therefore, hydraulic oil with slightly higher viscosity should be selected in summer. When the temperature of hydraulic oil continues to increase, the hydraulic components expand according to different coefficients, and the stuck fault may occur. When the time comes, shutdown and maintenance will be unavoidable. Prevention of high temperature hydraulic oil by daily inspection and maintenance.
  润滑脂温度过高,会导致润滑脂变软、附着性能降低、易于流失。此时,工作装置及回转装置会因为润滑不良导致高温、磨损、噪声等各种“幺蛾子”。
  If the temperature of the grease is too high, the grease becomes soft, reduces the adhesion performance, and is easy to be lost. At this point, the working device and rotary device will cause high temperature, wear, noise and other "unitary moths" because of poor lubrication.
  润滑脂失效的主要原因是凝胶的萎缩和基础油的蒸发损失,高温是导致润滑脂蒸发量增加、氧化变质和严重凝缩分油的罪魁祸首。因此,夏天一定要选择高温性能好的润滑脂,既要保持较高温度下的附着性能,也要保证失效过程缓慢。
  The main reason of grease failure is gel atrophy and evaporation loss of base oil. High temperature is the main culprit that leads to increase of grease evaporation, oxidation deterioration and serious condensation and separation of oil. Therefore, summer must choose high temperature performance of grease, not only to maintain the adhesion performance at a higher temperature, but also to ensure that the failure process is slow.
  加长臂挖掘机出租厂家认为,好的操作者有良好的维护习惯,比如在水温偏高时就近阴凉处怠速降温;经常检查防冻液是否缺少;经常查看风扇皮带的张力情况与疲劳度……都是保证挖掘机健康施工的良好习惯。此外,当挖掘机发动机温度过高时不要即刻熄火,防止发动机内部过热而造成拉缸事故,应怠速降温后再熄火停机。
  The elongated arm excavator rental manufacturer thinks that good operators have good maintenance habits, such as idling in the nearby shade when the water temperature is high; Check frequently for lack of antifreeze; Check the tension and fatigue of the fan belt regularly... Are good habits to ensure the healthy construction of excavators. In addition, when the engine temperature of the small excavator is too high, do not immediately flameout, to prevent the internal overheating of the engine and cause cylinder pulling accident, should idle speed cooling and then flameout stop.
