挖掘机冬季施工要注意什么?

日期:2022-01-08   来源:http://www.dybocheng.com
01为挖掘机选择合适的柴油
01 select appropriate diesel for excavator
首先冬季必须要换合适的柴油。由于温度比较低,所用柴油的黏度比较大,使得流动性变差,雾化不良,造成柴油机的动力性和经济性能下降。在冬季更好应该选择使用凝点较低的柴油,凝点更好比环境温度低5℃左右。记住在换柴油的时候,应该对燃油系统进行清洗。
First of all, we must change suitable diesel in winter. Because the temperature is relatively low and the viscosity of the diesel oil is relatively large, the fluidity becomes poor and the atomization is poor, resulting in the decline of the power and economic performance of the diesel engine. In winter, it is better to use diesel oil with low freezing point, which is about 5 ℃ lower than the ambient temperature. Remember to clean the fuel system when changing diesel.
02机油的更换保养
02 oil replacement and maintenance
其次,机油的选用和更换也需要特别的注意,冬季一般选择质量等级在CD级以上的。在东北及其它的高寒地区,冬天需要考虑更换标号较高的机油,比如10W-30标号的机油,在部分严寒地区,还会用专门的抗冻机油,还有在更换机油时,别忘记更换清洗机油滤清器。
Secondly, special attention should be paid to the selection and replacement of engine oil. In winter, the engine oil with quality grade above CD level is generally selected. In the northeast and other cold regions, it is necessary to consider changing the engine oil with higher grade in winter, such as 10W-30 engine oil. In some cold regions, special antifreeze engine oil will also be used. When changing the engine oil, don't forget to replace and clean the engine oil filter.
03冬季挖机蓄电池的保养
03 maintenance of excavator battery in winter
在冬季要特别注意对蓄电池的保养工作,冬季应该定期给蓄电池检测、充电以及调整电解液的密度,低温会使蓄电池容量下降。当检查挖机蓄电池电级接线时,若有绿色氧化物,应该用开水冲掉,吹干水分后更好喷上防护剂。冬季要对蓄电进行保暖措施,盖上棉被等衣物为蓄电池保暖,或者从机器上卸下,放置于温暖的环境下,第二天再装上。还有一点需要注意,蓄电池电解液液位太低时,要早上工作前加蒸馏水。
长臂挖掘机
Special attention shall be paid to the maintenance of the battery in winter. The battery shall be regularly tested, charged and the density of electrolyte shall be adjusted in winter. Low temperature will reduce the capacity of the battery. When checking the electric level wiring of the excavator battery, if there is green oxide, it should be washed away with boiled water. After drying the water, it is best to spray protective agent. In winter, thermal measures shall be taken for power storage. Cover clothes such as quilt to keep the battery warm, or remove it from the machine, place it in a warm environment, and then install it the next day. It should also be noted that when the electrolyte level of the battery is too low, distilled water should be added before work in the morning.
04冬季冷却系统的保养
04 maintenance of cooling system in winter
在低温条件下,需要注意对冷却系统的保养,在冬季一般会在挖掘机冷却系统中添加防冻液,加到冷却系统中的防冻液的比例应为温度时的比例。需要特别注意防冻液的更换周期比较长,一般为1-2年,冬季的时候要检查防冻液是否正常是否需要更换。
In low temperature conditions, attention should be paid to the maintenance of the cooling system. In winter, antifreeze is generally added to the excavator cooling system. The proportion of antifreeze added to the cooling system should be the proportion at the lowest temperature. Special attention should be paid to the long replacement cycle of antifreeze, generally 1-2 years. In winter, check whether the antifreeze is normal and whether it needs to be replaced.
05挖掘机玻璃的清洁保养
05 cleaning and maintenance of excavator glass
冬季温度比较低,在多数地区挖机都会处于长期放置状态,此时的挖机保养也不能忽略,应该让雨刷器离开挡风玻璃,防止冻结,在挖掘机的玻璃清洁时,喷水壶需要加入防冻液,这样水就不会结冰了。
The temperature is relatively low in winter. In most areas, the excavator will be placed for a long time. At this time, the maintenance of the excavator can not be ignored. The wiper should be kept away from the windshield to prevent freezing. When the glass of the excavator is cleaned, the spray kettle needs to add antifreeze so that the water will not freeze.
06检查空调、风扇皮带等
06 check the air conditioner, fan belt, etc
挖掘机换季保养工作有很多,虽然冬季空调不经常用,但是在冬天也要时不时检查下空调,避免长时间不使用出现的故障。此外还要检查风扇皮带、空调皮带的是否出现老化,避免皮带断裂问题出现。
There are many seasonal maintenance works for excavators. Although the air conditioner is not often used in winter, the air conditioner should be checked from time to time in winter to avoid faults caused by not using it for a long time. In addition, check whether the fan belt and air conditioning belt are aging to avoid belt fracture.
07挖掘机底盘的检查保养
07 inspection and maintenance of excavator chassis
对挖掘机底盘的螺母、螺栓、管路的检查工作,检查是否存在松动、管路泄露的情况。还需要对底盘的润滑点进行补脂润滑、脱漆喷漆防腐处理等等。
Check the nuts, bolts and pipelines of the excavator chassis for looseness and pipeline leakage. It is also necessary to carry out grease repair and lubrication, paint removal and anti-corrosion treatment for the lubrication points of the chassis.
