三菱发电机组动力不足，排蓝烟的诊断与处理。
发动机在低温或小负荷时排兰烟，温度升高后变为排深灰色烟雾，且动力不足。
①进气不畅，导致增压器内机油被吸入气缸燃烧所致。
② _油底壳内机油过多，机油超过了高限位。
③气门导管进机油。
④气缸严重窜机油。
⑤增压器转子轴严重磨损，挡油环损坏，致使增压器达不到额定转速，漏机油


为什么增压器是发动机上容易出故障的总成?
因为增压器的额定工作转速在每分钟13万转以上，且处于排气歧管出口处，温度（800℃以上），进、排气压力也较大，即高温、高压、高转速，所以对增压器的润滑和冷却及密封的要求比较高。为了增压器的使用寿命，在设计上要对增压器浮动轴承的润滑和冷却，同时，在使用中要求做到：
① 发动机起动后应怠速运转3-5分钟，不要立即加负荷，以增压器的良好润滑。主要原因是增压器位于发动机的顶部，如果发动机起动后增压器立即开始高速运转，就会导致机油压力未能及时升高给增压器供油，造成增压器缺油损坏，甚至烧坏整个增压器。
② 怠速时间不宜过长，一般不超过10分钟，怠速时间过长容易造成压气机端漏油。
③ _停车前不要立即关闭发动机，应怠速3-5分钟，以使增压器转速和排气系统的温度降下来，防止发生回热—机油结焦—轴承烧损等故障。经常性的不正确使用会使增压器损坏。
④ 长期未使用的发动机（一般超过7天），或新换增压器的发动机，在使用前应在增压器的进油口加注机油，否则会因润滑不良降低寿命或损坏增压器。
⑤ 定期检查各连接部位是否有松动漏气/_漏油现象，回油管是否通畅，如有应及时排除。
⑥ 空气滤清器清洁，并按要求定期更换。
⑦ 定期更换机油/_机油滤清器。
⑧ 定期检查增压器轴的径向轴向间隙，轴向间隙应不大于0.15毫米，径向间隙为：叶轮与压壳的间隙不小于0.10毫米，否则应请人员维修，以免扩大损失。

三菱发电机组动力不足，排灰白烟的故障诊断分析如下：
发动机动力不足，排气管排灰白烟雾，一般是喷油时间过迟所致。这时不仅高速运转不良，加速不灵敏，而且温度易过高。
① 喷油提前角过小。
② 喷油器雾化不良。
③ 发动机温度过低。
④ 气缸内有水。
⑤ 柴油中有水


三菱发电机组动力不足，排浓黑烟的故障原因分析：
发动机动力不足，转速不均，排气管排浓黑烟雾的现象有两种：一种是连续排黑烟；另一种是断续排黑烟，且发动机抖震。发动机动力不足且连续排黑烟，是发动机大多数缸或所有的缸均供油量过多，燃油与空气混合比例失调，燃烧时严重缺氧，柴油燃烧不完全，悬浮游离状的碳元素随废气一同排出而形成的。若排气管是断续排黑烟，且伴有“突突”声，说明个别缸燃烧不完全。归纳原因如下
① 喷油泵调试不当，使供油量过多，燃烧不完全。
② 多数喷油器的喷射质量差。
③ 供油不正时。
④ 进气门开启高度降低、开启时间推迟，导致进气不足。
⑤ 空气滤清器滤芯过脏或空气滤清器安装有误，使空气不流畅。
⑥ 增压器的增压效能下降。
⑦ 燃油质量过差。

Matters needing attention in the assembly of Mitsubishi accessories Diesel generator

1. The equipment address of the Mitsubishi accessory motor set should be well ventilated, with satisfactory air inlet at the generator end and good air outlet at the diesel engine end. The area of the air outlet should be greater than 1.5 times the area of the water tank.
Mitsubishi accessories
2. The surrounding area of Mitsubishi accessory electric unit equipment should be kept clean, and items that can corrode gases and vapors such as acids and alkalis are strictly prohibited from being placed nearby. If conditions permit, rescue equipment should be equipped.

3. When using Mitsubishi accessory generator sets indoors, it is necessary to lead the exhaust pipe to the outdoors. The diameter of the exhaust pipe of the muffler and the elbow connecting the pipeline should not exceed three to ensure smooth smoke exhaust. The pipeline should be tilted down 5-10 degrees to avoid rainwater injection; If the exhaust pipe is straight up, a rain cover should be installed.

4. When concrete is used as the foundation, the levelness of the diesel generator set shall be measured with a level ruler when the equipment is used to fix the unit on a horizontal foundation. There shall be special shockproof pads or anchor bolts between the generator set and the foundation.

5. The generator casing should have reliable protective grounding. For generators with directly grounded neutral points, professional personnel should ground the neutral points and equip them with lightning protection devices. It is prohibited to use mains grounding equipment for direct neutral point grounding.

The bidirectional switch between the Mitsubishi accessory generator and the main power supply is very reliable to prevent reverse power transmission. The wiring reliability of the bidirectional switch needs to be checked and approved by the local power supply department.

Here are four main uses of diesel generator set.

1、 Self-contained power supply

Some power users have no network power supply, such as military camps, workstations, radar stations, etc. These places are far away from the mainland, remote pastoral areas, rural areas, and desert plateau, so they need to provide their own power supply. The so-called self provided power supply is self used power supply. In the case of low power generation, diesel generator sets are often a better choice for self provided power supply.

2、 Backup power supply

The backup power supply, also known as emergency power supply, is mainly used by some electricity consuming units, although they have relatively safe and reliable network power supply, to prevent unexpected situations such as circuit failures or temporary power outages, they still configure their own power supply for emergency power generation. It can be seen that the backup power supply is actually a self backup power supply, not used as the main power supply, but as a means of rescue in emergency situations.

3、 Alternative power supply

The role of standby power supply is to make up for the shortage of network power supply. There may be two situations. One is that the Electricity pricing of the grid is too high, and diesel generator sets are selected as the alternative power supply from the perspective of cost saving; Another type is when the power supply in the power grid is insufficient, the use of power in the grid is limited, and the power supply department has no choice but to switch and limit power everywhere. At this time, in order to ensure normal production and work, the power consumption unit needs to replace the power supply to alleviate the situation.

4、 Mobile power supply

Mobile power is a kind of power generation facility that has no fixed place of use but is used everywhere. The diesel generator set is a better choice for mobile power because of its portability, flexibility and ease of operation. Mobile power is generally designed for power vehicles, including self powered vehicles and trailer powered vehicles.

一、质量是影响的价格的一个基础数据，康明斯发电机的价格是围绕着康明斯发电机价值在上下波动的。
二、市场的需求量也是决定价格的一个因素。道理很简单，需求增多，价格增长，需求减少，价格下降。天气越来越热，用电量明显增加，自然天气也会带来康明斯发电机价格上涨。天气冷的时候，相对而言对康明斯发电机的需求会减少，那么价格就会下降。
三、市场供给量会直接影响价格。供不应求，价格上升，反之，价格降低。所以一个稳定的康明斯柴油发电机组价格需要成熟的市场控制。
