Diesel Generator Tech

  Since January this year, the southern region has suffered from continuous rainy weather. Improper handling of diesel generator sets during use is prone to moisture problems, especially the damping of the motors of the generator sets, which has a great impact on the life and work of the generator sets. At this time, the user must dry the damp diesel generator set . For the relevant drying method, the user can refer to the following methods: 1. Short-circuit the three-phase outlet of the stator winding and connect it firmly. 2. Adjust the resistance of the voltage regulating rheostat in the excitation circuit to the maximum value. If the resistance value is not enough, add another resistance to increase the resistance value. 3. Start the generator set , slowly increase it to the rated speed, and then slowly adjust the excitation current. The excitation current is determined according to the damp condition of the generator set, and the short-circuit current of the stator ...

 What is the emergency shutdown of silent diesel generator set with load? That is, the silent diesel generator set suddenly stops suddenly in the process of running with load. This operation is harmful to the diesel engine and is not allowed. This wrong operation will seriously affect the service life of the silent diesel generator set and should be avoided in daily operation.   Emergency shutdown with load or immediate shutdown after unloading the load suddenly, the circulation of the cooling system water stops after the silent diesel generator set is turned off, the heat dissipation level drops sharply, the heated parts are not cooled, and it is easy to cause the cylinder head, cylinder liner, cylinder block and other components overheating, causing cracks, or over-expanding the piston and getting stuck in the cylinder liner. At the same time, when the silent diesel generator set stops, there is no idling to reduce heat, which will cause insufficient oil conte...

As a user, I believe that when you purchase a diesel generator set, the generator manufacturer must have emphasized to you that you need to maintain the diesel generator set regularly, so you know why it is very important to maintain the diesel generator set regularly. Is it important? In this article, Jiangsu Starlight Electricity Equipments Co.,Ltd. will tell you the reasons for this from the engine oil. Most people don't know that engine oil can degrade over time even when the engine is not running at all. If the life expectancy is 1 year, it doesn't mean it can maintain 100% quality in a year. It started to degenerate from day one, but still reached acceptable tolerance levels after a year. Now, if you extend your service interval to 18 months, that doesn't mean your oil is half as good as new, because you've exceeded the recommended 50% change. Oil does not degrade linearly, which means it may retain its usefulness and then suddenly lose 90% of its l...

The engine of the 290kW Cummins generator set adopts the Cummins patented PT fuel system, which enables the set to have higher reliability, durability, power and fuel economy while meeting environmental emissions. So do you know what its crankshaft position sensor failure strategy is? (1) The concept of failure strategy. The so-called failure strategy is the operation mode of the electronically controlled diesel engine under the fault state. When the diesel engine is in the following conditions, the control strategy will enter the Limphome state. 1. The crankshaft position sensor is damaged or the signal circuit is open or short circuited. 2. The camshaft phase sensor is damaged or the signal circuit is open or short circuited. 3. The oil pressure sensor of the common rail is damaged or the circuit is open or short circuited. 4. The oil metering valve of the high-pressure oil pump is damaged or the drive circuit is open or short-circuited. 5. The electronic throttle sensor is d...

  Today, we will briefly introduce the problem of fault inspection of blown fuse or disconnected thermal relay when the generator set is started. Troubleshooting steps. Check whether the fuse capacity of the generator set is appropriate, if it is too small, you can change it and try again. If the fuse continues to blow, check whether the drive belt is too tight or the load is too large, whether there is a short circuit in the circuit, and whether the motor itself is short circuited or grounded. Ground fault checking method. Use a megohmmeter to measure the insulation resistance of the motor winding to ground. When the insulation resistance is lower than 0.2MΩ, it means that the winding is seriously damp and should be dried. If the resistance is zero or the calibration lamp is close to normal brightness, the phase is grounded. Winding grounding generally occurs at the outlet of the motor, the inlet hole of the power line or the winding extension slot. For the latter ca...

 What is the reason for the damage to the accessories of the diesel generator set? In the process of using diesel generator sets, due to some accessories were damaged, we often need to repair and maintenance to ensure the normal operation of diesel generator sets. As a diesel generator set manufacturer, we would like to give some advice to our customers. Sometimes it is not necessary to wait until the diesel generator set is out of operation before remembering to replace these parts. It can be based on the maintenance interval given by the diesel generator set manufacturer. I judge whether to replace some wearing parts in advance. In order to avoid sudden failure when the diesel generator set needs to be used, it will cause its own loss.   1. The parts of diesel generator set are deformed. Because when using a diesel generator set , it will cause some attachments to deform due to its own force. Especially some basic parts, such as cylinder block and cylinder head, ...

 When the diesel generator sets operation, there are may be some small faults occurs, such as oil leakage from high-pressure oil pipes. Although small faults have big hidden dangers, oil leakage will also cause economic waste. Therefore, in this article, Starlight Power Generation Equipment will introduce in detail the cause analysis of oil leakage from high pressure oil pipes of diesel generator sets and the solutions. Oil leakage occurs when the joints of the engine oil pipes are cracked or broken. Generally, the high-pressure oil pipes of the two cylinders of diesel engine I and VI are easier to break than those of other cylinders. In addition to the quality of the oil pipe itself, the main reason is that when the fuel injection pump is repaired and dismantled, the fixed high-pressure oil pipe clamp is missing or installed in an inappropriate position.  The oil leakage in the connection part of the high-pressure oil pipe may be caused by the poor sealing of the...

 Under the prerequisites of mastering the working principle, structure, adjustment and maintenance of diesel generator sets , it is also necessary to deeply understand the conditions under which the generator set operates normally and under which conditions it is prone to failure. If a fault is caused, how to analyze the cause of the fault according to the problem phenomenon, through in-depth and detailed analysis, propose the correct processing method, and quickly and accurately eliminate the fault problem. Diesel generator failure problems often show one or more unique failure problem phenomena. Different working conditions, the phenomenon of failure problems will be different. These fault phenomena are usually audible, visible, tactile or measurable in nature. All in all, the failure phenomenon has the following five aspects: 1. The function is abnormal. If the unit is not easy to start. With no load (that is, slow down or stop after loading). The speed and frequenc...
