在冬季来临之前搅拌车需要提前准备什么?
来源:https://www.cnzkjf.com/ 日期:2021-09-22
一、冬天气温大幅度的降低,夏季用机油黏度变稠,曲轴循环阻力变大,机油流动性差,造成混凝土搅拌车活塞和缸套磨损加大。因此要改用标号低流动性好的冬季机油。在混凝土搅拌车厂家的建议更换型号为10W-30或5W-30的机油,前者在零下15度时车可以启动,后者在零下25度时可以启动。
1、 The temperature decreases greatly in winter, the viscosity of engine oil becomes thicker in summer, the circulating resistance of crankshaft becomes larger, and the fluidity of engine oil is poor, resulting in increased wear of piston and cylinder liner of concrete mixer. Therefore, use winter engine oil with low grade and good fluidity. It is recommended by the concrete mixer manufacturer to replace the engine oil of 10W-30 or 5W-30. The former can start at minus 15 degrees and the latter can start at minus 25 degrees.
二、检查防冻液
2、 Check antifreeze
加注防冻液前千万要对混凝土搅拌车发动机冷却系统进行一次认真的清洗,应使用10%的烧碱水溶液浸泡水箱一个小时,再将冲洗液排放,然后用软化水反复冲洗23次,以混凝土搅拌车发动机冷却系统中原积存的水垢,冲洗完后才能加注防冻液。同时,在加注防冻液前要检查混凝土搅拌车发动机冷却系统有无渗漏现象,并应及时排除后才能使用防冻液。
Before adding antifreeze, the engine cooling system of the concrete mixer shall be carefully cleaned. The water tank shall be soaked with 10% caustic soda solution for one hour, and then the flushing solution shall be discharged, and then repeatedly washed with softened water for 2 to 3 times to remove the scale accumulated in the cooling system of the concrete mixer engine. Antifreeze can be added only after washing. At the same time, before filling antifreeze, check whether there is leakage in the engine cooling system of concrete mixer, and remove it in time before using antifreeze.

防冻液使用中要实行定期检查。防冻液的有效期一般2年,为了减少浪费,防冻液加注后不要随意更换。但是,应对使用中的防冻液实行定期定项检查,如发现比重增大、防冻液变稠、冰点上升,以及防冻液变浊、变质、变味、发泡等应及时更换。要选择低于车使用地区较低温度10度左右并具备冬季防冻、夏季防沸、防腐、防水垢的长效型的防冻液。
Regular inspection shall be carried out during the use of antifreeze. The validity period of antifreeze is generally 2 years. In order to reduce waste, do not replace the antifreeze after filling. However, the antifreeze in use shall be inspected regularly. If the specific gravity increases, the antifreeze thickens, the freezing point rises, and the antifreeze becomes turbid, deteriorated, tastes and foamed, it shall be replaced in time. Choose a long-term antifreeze that is about 10 ℃ lower than the lower temperature in the area where the vehicle is used, and has antifreeze in winter, anti boiling, anti-corrosion and waterproof scale in summer.
三、要检查电瓶
3、 Check the battery
混凝土搅拌车蓄电池较怕低温,在冬季来临之前,须补充蓄电池的电解液,并检查存电情况,温暖天气时使用正常的蓄电池,在寒冷的气温下经常失效,故蓄电池的保养应引起司机朋友的特别重视。要看是否需添加蒸馏水,同时察看清洁电瓶的极柱,并检测电瓶液的比重,对启动无力、使用时间超过两年的电瓶建议换掉。
The battery of concrete mixer truck is afraid of low temperature. Before winter, it is necessary to supplement the electrolyte of the battery and check the power storage. The normal battery is used in warm weather and often fails in cold temperature. Therefore, the maintenance of the battery should be paid special attention to by the driver's friends. Check whether distilled water needs to be added. At the same time, check the pole column of the clean battery, and check the specific gravity of the battery liquid. It is recommended to replace the battery with weak start-up and used for more than two years.
