    山东装载机配件之增压器使用时应注意什么?
    2014-6-28 10:05:31

    山东永保机械从事装载机生产及销售行业已有多年时间,在实践中积累了大量的工作经验,并得到新老客户的一致好评。由于装载机的增压器经常处于高速、高温下工作,增压器废气涡轮端的温度在700-900℃,增压器转子以几万转到二十多万转的高速旋转,因此为了保证增压器的正常工作,在使用中应注意以下几点。
    1、保持清洁
    发动机长时间高速运转后,不能立即熄火。发动机工作时,有一部分机油供给涡轮增压器转子轴承润滑和用于冷却的。正在运行的发动机突然停机后,机油压力迅速下降为零,增压器涡轮部分的高温传到中间,轴承支承壳内的热量不能迅速带走,而同时增压器转子仍在惯性作用下高速旋转。因此,发动机热机状态下如果突然停机,会引起涡轮增压器内滞留的机油过热而损坏轴承和轴.特别要防止猛轰几脚油门后突然熄火。
    After the high-speed operation of the engine for a long time, you can not turn off immediately. When the engine work, some of the oil supply turbocharger rotor bearings for lubrication and cooling. After running the engine suddenly stopped, the oil pressure to drop rapidly to zero, the high temperature reached turbocharger middle part of the heat bearing housing can not be taken away quickly, and high-speed rotation inertia turbocharger rotor while still . Therefore, if the state of the engine heat engine suddenly stopped, causing the turbocharger oil retention overheating damage the bearings and shaft. Particularly to prevent sudden flameout Meng kicks after the throttle.  
    2、经常注意检查增压器的运转情况 
    在出车前、收车后,应检查气道各管的连接情况,防止松动、脱落而造成增压器失效和空气短路进入气缸。
    In front of the bus, after closing the car, check the connections of each airway tube to prevent loosening, shedding booster failure caused by a short circuit and air into the cylinder.
    3、不能着车就走 
    发动机发动后,特别是在冬季,应让其怠速运转一段时间,以便在增压器转子高速运转之前让润滑油充分润滑轴承,所以刚启动后千万不能猛轰油门,以防损坏增压器油封。
    After the engine is started, particularly in winter, to be allowed to idle for a period of time prior to the turbocharger rotor at high speed to allow sufficient oil lubricated bearings, so do not be started immediately after the throttle Meng, to prevent damage to the turbocharger seal. 
    4、由于增压器经常处于高温下运转,它的润滑油管线因受高温作用,内部机油容易有部分的结焦,这样会造成增压器轴承的润滑不足而损坏。因此,润滑油管线在运行一段时间后要进行清洗。
    Due to high temperatures often in the turbocharger operation, due to its high temperature oil pipelines, oil prone to internal coke part, this will result in insufficient lubrication of the bearing turbocharger damage. Thus, oil pipeline after running for some time to be cleaned.  
    5、不能立即熄火 
    发动机长时间高速运转后,不能立即熄火。发动机工作时,有一部分机油供给涡轮增压器转子轴承润滑和用于冷却的。正在运行的发动机突然停机后,机油压力迅速下降为零,增压器涡轮部分的高温传到中间,轴承支承壳内的热量不能迅速带走,而同时增压器转子仍在惯性作用下高速旋转,因此,发动机热机状态下如果突然停机,会引起涡轮增压器内滞留的机油过热而损坏轴承和轴.特别要防止猛轰几脚油门后突然熄火。

When the engine work, some of the oil supply turbocharger rotor bearings for lubrication and cooling. After running the engine suddenly stopped, the oil pressure to drop rapidly to zero, the high temperature reached turbocharger middle part of the heat bearing housing can not be taken away quickly, and high-speed rotation inertia turbocharger rotor while still Therefore, if the state of the engine heat engine suddenly stopped, causing the turbocharger oil retention overheating damage to the bearings and shaft. particularly to prevent sudden flameout Meng kicks after the throttle.
