    装载机冬季如何保养
    发布时间:2014-5-5 17:01:21    浏览:218次

    装载机冬季保养必不可少,在装载机停止工作的期间,要提前更换相应的柴油和润滑油,那么具体的细节该怎么做呢?

    一、选择优质防冻液

    衡量防冻液主要有两个指标:一是冰点,普通型防冻液可达到—40℃,而优质防冻液能达到—60℃左右;二是沸点,防冻液至少应达到108℃。
    Antifreeze measure has two main indicators: First, freezing, ordinary type of antifreeze can reach -40 ℃, and quality antifreeze can reach -60 ℃; Second boiling point, antifreeze should reach at least 108 ℃.
    二、水泵检查
    有些设备在更换防冻液后出现机油内有防冻液的现象,这是由于水泵水封老化失效,造成防冻液通过水封进入润滑腔,最终到达油底壳内。因此更换防冻液后应密切观察机油油位。发现油位升高,应?;觳?,一般采用更换水泵水封或水泵总成方法。修复后要在机器空载怠速运转下,用新机油带走进入发动机润滑系统残留的防冻液,注意:缩短下次更换机油的间隙时间,以确保发动机润滑系统正常发挥功效。
    Some devices have appeared in the replacement of antifreeze in the antifreeze oil phenomenon, which is due to the aging of the pump seal failure resulting antifreeze into the lubrication chamber through the seal, and finally to the oil sump. So after replacing antifreeze oil level should be closely observed. Found that the oil level rises, should stop to check, generally used to replace the water pump seal or pump assembly methods. To repair the machine after idling under load, with the new oil into the engine lubrication system away residual antifreeze Note: the next oil change interval shorter time to ensure normal functioning of the engine lubrication system effectiveness.
    三、冷却系统防腐滤芯
    冷却系统防腐滤芯含有离子交换树脂、防蚀剂、镁板等添加剂,可以有效?;び泄夭考?。离子交换树脂可防止水垢的形成。防蚀剂可以在冷却液套中形成防蚀膜以防止氧化。因为镁的金属活性比铁强,冷却液中的腐蚀性离子首先与镁板发生反应,有效防止铁被腐蚀。另外防腐滤芯还能过滤铁锈、水垢和泥沙。防腐滤芯须与防冻液同期更换,而且防腐滤芯应第1000小时(发动机工作时间)更换,确保防腐滤芯起到有效?;ぷ饔?。
    Cooling system corrosion cartridge containing an ion exchange resin, a corrosion inhibitor, and other additives magnesium plate, can effectively protect the relevant member. Ion exchange resin prevents the formation of scale. Corrosion inhibitor film can be formed in the coolant jacket in order to prevent oxidation. Because magnesium metal active than iron, corrosive coolant magnesium ion reaction occurs first plate to effectively prevent corrosion of iron. Another filter can filter corrosion rust, scale and sediment. Preservative filter must be replaced with the same period in antifreeze and corrosion protection filter should first 1000 hours (engine hours) replacement to ensure corrosion protection filters play an effective role.
    四、润滑油选用
    应根据当地气温,结合润滑油的凝点、倾点和黏度选用合适的润滑油。凝点高的润滑油不能在低温下使用。相反在气温较高的地区则没有必要使用凝点低的润滑油。凝点和倾点都是润滑油低温流动性的指标,两者无原则性的性别,只是测定方法稍有不同。同一润滑油的凝点和倾点并不完全相同,一般倾点都高出凝点2--3℃。
    Should be based on the local temperature, combined with oil pour point, pour point and viscosity appropriate choice of lubricants. High pour point oil can not be used at low temperatures. At higher temperatures the opposite region is not necessary to use a low pour point oil. Pour point and the pour point is the indicator of the low temperature fluidity lubricants, there was no gender principle, only slightly different measuring methods. Same oil pour point and pour point are not identical, are generally higher pour point pour point 2 - 3 ℃.
    六、设备三漏检修
    热胀冷缩现象在液压系统、气路、水路的密封件,尤其是橡胶类O型圈、矩型圈等密封件上表现更为明显,气温持续低于0℃时,机器会出现漏油、漏气、漏水现象,特别是气温持续接近-10℃时。在设备进入冬季前要对整机三漏情况进行全面检修,排除三漏故障和隐患故障。
    Thermal expansion and contraction phenomena in the hydraulic system, gas, water seals, especially on the rubber O-ring, rectangular ring seals to become more evident, the temperature remained below 0 ℃, the machine will appear spill , leakage, water leakage, especially when temperatures consistently close to -10 ℃. In front of the whole device into the winter to conduct a comprehensive overhaul of three missing exclude leakage of hidden faults and failures.
    七、检修电气设备
    冬季老化设备多发生启动困难故障,因此前的换季保养时检查并更换老化电气线路和部件是减少启动困难一个必不可少的举措,还需彻底检查保养蓄电池。暖风设备是冬季户外作业必不可少的,因此在严冬之前应检查暖风设备工作情况,修复暖风设备。
    Winter aging equipment malfunction occurred difficult to start, so check and replace aging electrical wiring and components are essential to reduce the difficulty in starting a pre-season move when maintenance needs thorough inspection and maintenance batteries. Heating equipment is essential for outdoor work in winter, so you should check before winter heating equipment work, repairing heating equipment.
