柴油发电机作业无力的表现是什么？

咱们和贵州发电机小编一起来了解一下：

柴油发电机运转无力，并在各种转速下冒浓烟。这种现象主要是由于喷油雾化不充分和加油时间不正确所致。

Diesel generators run weakly and emit heavy. This is mainly due to insufficient fuel injection atomization and incorrect refueling time.

1. 喷油嘴或出油阀磨损较为严重的，滴油，雾化不好，燃烧不充分。

The fuel injection nozzle or the fuel delivery valve is  severely worn, dripping, poor atomization, and insufficient combustion.

2. 喷油嘴在汽缸盖上的安装位置不正确，使用过厚或过薄的铜垫子或铝垫圈，使喷油嘴喷射不当，燃烧不充分。

The installation position of the fuel injector on the cylinder head is not correct. The use of copper pads or aluminum washers that are too thick or too thin may cause improper injection of the fuel injector and insufficient combustion.

3. 喷油泵传动系统部件出现磨损，导致供油过迟。

The components of the fuel injection pump transmission system are worn out, causing the fuel supply to be too late.

4.没有调整燃油供应时间。

The fuel supply time has not been adjusted.

一、在转速不稳定时，柴油发动机冒烟。

When the speed is unstable, the diesel engine emits smoke.

1.不同气缸的燃油供应不一致。喷射泵及喷油嘴磨损或调整不当，易引起各缸供油不均匀。判断供油不一致的方法可以使柴油发电机空车运行。采用停缸法，轮流停一缸供油，速度计测量速度。在断气缸时，各气缸供油量一致，断气量变化应相同或很接近，若发现转速变化有较大差异，则应进行喷油泵供油量调整。

The fuel supply of different cylinders is inconsistent. The abrasion or improper adjustment of the jet pump and fuel injection nozzle can easily cause uneven fuel supply in each cylinder. The method of judging the inconsistency of fuel supply can make the diesel generator run empty. Using the cylinder stop method, one cylinder is stopped for oil supply in turn, and the speed meter is used to measure the speed. When the cylinder is broken, the fuel supply of each cylinder is the same, and the change of the cut-off volume should be the same or very close. If there is a big difference in the speed change, the fuel supply of the fuel injection pump should be adjusted.

2. 柴油供油系统油路内有水汽或漏气，也会造成喷油泵供油欠佳。

Water vapor or air leakage in the oil circuit of the diesel fuel supply system can also cause poor fuel supply from the fuel injection pump.

二、柴油发电机转速低，烟雾弥漫，但高速基本上正常。

Diesel generators have low speed and smoke, but the high speed is basically normal.

该表现为气缸漏气，在高转速时漏气少，故能基本正常工作。气体泄漏导致温度低，不容易引起火灾。柴油发电机运行过程中，如从加油口排放大量烟气，或曲轴运行部分有“吱.”的漏气声，且低速时较明显，则可判定为缸体与活塞间漏气。其他两个可能漏气的地方是气门和气缸垫。

It’s that the cylinder leaks air, and the air leaks less at high speeds, so it can basically work normally. Gas leakage causes low temperature and is not easy to cause fire. During the operation of the diesel generator, if a large amount of smoke is emitted from the fuel filler port, or there is a "squeak" air leakage sound in the crankshaft operation part, and it is obvious at low speed, it can be judged as air leakage between the cylinder block and the piston. The other two possible leaks are the valve and cylinder head gasket.

三、柴油发电机的表现功率欠佳，但空转时和供油量较少时排气口没有烟，供油量大时容易冒黑烟。

The diesel generator power is not good, but there is no smoke at the exhaust port when idling and when the fuel supply is small, and it is easy to emit black smoke when the fuel supply is large.

1.空气过滤器滤芯堵住了，造成柴油发电机进水欠佳，但功率不够。

The air filter element is blocked, causing the diesel generator to enter poor water, but the power is not enough.

2.气门间隙，导致气门开度不够，进气量欠佳。

The valve clearance is too large, resulting in insufficient valve opening and poor air intake.

3.排气管内积炭太多，排气口阻力。

Too much carbon deposits in the exhaust pipe, and the exhaust port resistance is too large.
