1.发电机进气温度异常升高的维修方法。
如果发电机出口空气温度和定子线圈温度没有超过规定值，发电机的输出可能不会降低，但应及时找出原因并进行调整。当超过规定值时，检查前应降低发电机的输出。

2.发电机线圈和铁芯温升异常的维修方法。
(1)如果超过规定值，应迅速降低负荷；
(2)迅速检查冷却空气温度，检查滤尘器是否堵塞；
(3)检查空冷器进出口阀门是否关闭。

3.发电机过载维修方法。
发电机允许短期过载运行，过载参数和时间按下表确定:
在过载的情况下，需要在规定时间内将负载电流降至允许值，同时监测发电机各部分温度不超标。
4.发电机三相不平衡电流超标的维修方法。
当发电机三相不平衡电流超过规定值时，要检查是否是变压器电路故障引起的，否则要降低定子电流使其不超过规定值，同时要严密监视发电机各部分的温度。当发现温度异常升高，不平衡电流增加时，应紧急停机。并网运行时，不平衡电流不超过额定值的10%，所以降低送出的有功功率，看不平衡电流是否变小。如果变小了，是外网造成的，可以维持运行，也可以断开外网。
5.发电机运行中其中一个指示表突然指示异常或消失的维修方法。

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。

柴油发电机组空气滤清器对机组起着重要的作用，需要定期更换。用户应定期清洁和更换发电机组空气滤清器滤芯，以免滤芯上粘附灰尘过多而造成进气阻力增大、发动机功率降低、油耗上升等现象。下面江苏玉柴厂家给大家介绍一下柴油发电机组空气滤清器滤芯更换方法：
1、用压缩空气将吹净附在壳体上的灰尘。
　　2、拆下空气滤清器罩盖和滤芯，报废滤芯。
　　3、用清洁覆盖物盖住空滤器壳体内通向压气器进口，防止灰尘进入进气系统。
　　4、用压缩空气将吹净空滤器壳体内部。
　　5、检查新的滤芯是否完好无损，取下压气机进口处覆盖物。
　　6、安装新的滤芯，并确保空滤器两端密封可靠;安装空滤罩盖。

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.
