为什么加长臂挖掘机的发动机会积炭?如何处理

日期:2019-08-28   来源:
  发动机是挖掘机的动力源,如果发动机出现问题将直接影响挖掘机的正常动力。挖掘机发动机最常见的故障是软弱、高温、异常噪声、积炭等。今天和朋友一起来谈谈为什么发动机积碳故障?
  Engine is the power source of excavator, if the engine problems will directly affect the normal power of excavator. The most common faults of excavator engine are weak, high temperature, abnormal noise, carbon deposit and so on. Today, I would like to talk with my friends about why the engine carbon deposit failure?
  首先,什么是碳沉积?碳沉积是不完全燃烧的产物。发动机运行时,不饱和烯烃和胶体在油和燃料中高温不完全燃烧时会产生沉淀物,这种炭黑物质常被称为碳,碳可分为阀碳、燃烧室碳和进气管碳。
  First, what is carbon deposition? Carbon deposition is the product of incomplete combustion. When an engine is running, unsaturated olefins and colloids will produce precipitates when they are incompletely burned at high temperatures in oil and fuel. This carbon black material is often called carbon. Carbon can be divided into valve carbon, combustion chamber carbon and intake pipe carbon.

  挖掘机发动机在使用中出现的各种故障,炭素是常见的一种,无需进一步说明,下面就直接告诉大家,挖掘机发动机产生炭素的三个原因。
  Carbon is one of the common faults in the use of excavator engine. Without further explanation, I will tell you directly that there are three reasons for carbon in excavator engine.
  1. 挖掘机日常用油中杂质过多。在现实生活中,燃油是不可能完全纯净的,过滤器也有它的过滤极限。燃油中的一些小杂质在燃烧后会碳化并沉积在气缸内,从而产生积炭。
  1. There are too many impurities in the daily oil used by excavators. In real life, fuel cannot be completely pure, and filters have their filtering limits. Some small impurities in the fuel will be carbonized and deposited in the cylinder after combustion, resulting in carbon deposition.
  2. 发动机运动部件的磨损。发动机高速运行时,气缸套、气门、活塞、活塞环等由于磨损会产生杂物,杂物燃烧熔化后沉积在气缸内,导致气门积碳。
  2. Wear of engine moving parts. When the engine runs at high speed, the wear of cylinder liner, valve, piston and piston ring will produce impurities, which will deposit in the cylinder after combustion and melting, resulting in valve carbon deposition.
  3.进气不够纯净,过滤器不能完全过滤掉进入空气中的杂质。一些杂质会进入燃烧室,燃烧碳化后会发生积炭。
  3. Intake air is not pure enough, the filter can not completely filter out impurities into the air. Some impurities will enter the combustion chamber and carbon deposits will occur after combustion and carbonization.
  发动机碳排放的影响是什么?
  What is the impact of engine carbon emissions?
  1. 积碳会降低发动机的功率,导致发动机功率输出不均;它也增加了燃料消耗。
  1. Carbon deposition will reduce engine power, resulting in uneven engine power output; it also increases fuel consumption.
  2. 积炭在活塞沟槽中越来越多,会附着在活塞环上,造成活塞环变形,切割缸套、缸套等。
  2. More and more coke deposits in piston grooves will be attached to piston rings, resulting in deformation of piston rings, cutting cylinder liners, cylinder liners and so on.
  3.大量的积炭有时会堵塞喷油器,因此有必要更换喷油器。
  3. A lot of carbon deposits sometimes block the injector, so it is necessary to replace the injector.
  4. 过多的积炭会导致阀门应力不均、阀杆断裂、阀架断裂等故障。
  4. Excessive carbon deposition will lead to uneven valve stress, valve stem fracture, valve rack fracture and other faults.
  5. 燃烧室积炭严重,导致气缸爆震,低速加速产生噪声,损坏活塞和曲轴,影响挖掘机的安全。
  5. The serious carbon deposit in combustion chamber leads to cylinder detonation, low speed acceleration produces noise, damages piston and crankshaft, and affects the safety of excavator.
  如何解决固碳问题?
  How to solve the problem of carbon sequestration?
  1. 为防止积碳,请为您的挖掘机选择高品质的油和燃料,因为积碳的主要原因是燃料中的杂质,如蜡和凝胶。
  1. in order to prevent carbon deposition, please select high quality oil and fuel for your excavator, because carbon deposition is mainly caused by impurities such as wax and gels in fuel.
  2. 当发动机排碳时,朋友可以购买除碳添加剂,减少口香糖、沉积物的吸附,也是减少排碳的方法之一。
  2. When the engine exhaust carbon, friends can buy carbon removal additives to reduce the adsorption of chewing gum and sediment, which is also one of the ways to reduce carbon emissions.
  3.最直接的方法是机械抛光。您可以使用钢刷,刮板,竹子或金刚砂布抛光,清洁和积累碳。
  3. The most direct method is mechanical polishing. You can use brushes, scrapers, bamboo or emery cloth to polish, clean and accumulate carbon.
