Diesel Generator Tech

When using diesel generator sets for a long time, it is essential to know the functions of the emergency shutdown device and the alarm switch. (1) Emergency Shutdown Device of Diesel Generator Sets The emergency shutdown device of Shangchai diesel generator sets can be operated electrically, mechanically, or hydraulically. Users should be familiar with the shutdown mode and location of the shutdown device installed on their diesel generator engines, the conditions for activating various shutdown devices, and the reset steps required before restarting. The working principles of all electric shutdown devices are similar. When a certain critical operating condition occurs, a switch is activated to stop the engine. The shutdown device needs to be reset before the engine can be restarted.  The shutdown device should be inspected by the company's personnel every 1000 working hours. The engine unit staff can test the hydraulic - mechanical shutdown device every 500 working hours. Gene...

Electricity plays an important role in our daily lives and it may cause inconvenience and potential risks to us when the supply of power fails. Fortunately, emergency diesel generators can provide a reliable power supply during power shortages. To ensure the generators work smoothly in the event of a power cut, regular maintenance is essential. In this article, we will explore several important things you need to know about maintenance of your emergency diesel generator.  What is an emergency diesel generator? An emergency diesel generator is a device that is often designed to mainly run fuel oil and can supply electrical power to a facility during a blackout or emergency. These generators serve as a backup source of power when the main source of power fails. They are typically configured to start automatically when there is a power loss and assume essential facility loads until the utility power returns. Why generator maintenance is important? Regular maintenance of diesel ...

How to maintain lubricating oil system of emergency diesel generator set? 1.Select suitable engine oil for emergency diesel generator . Generally speaking, the instruction manual of each generator set specifies the type of lubricating oil used for the unit. If there is no lubricating oil specified in the manual, the lubricating oil of similar brand can be used. Never mix different brands of engine oil. 2.During the use of emergency generator set, often check the quality of lubricating oil. Check the mechanical admixture in the engine oil when the engine is hot, and pull out the engine oil scale to check. Why should the oil level be suitable? The oil level of the diesel generator set shall be checked before starting each time to ensure that the oil level is within the specified range. 1.Low oil level will causes over wear, tile burning and cylinder pulling. 2.High oil level will cause oil leaking into cylinder, combustion chamber carbon deposit, piston...

We can install generator damp proof heater and control panel moisture-proof heater on emergency diesel generator to resolve moisture problem. Because generator damp proof heater and and control panel moisture-proof heater is optional part, when users purchase, should tell the supplier. The attention on moisture-proof for diesel generator set: 1.Heating and drying shall be carried out in clean air, and the generator shall be blown clean with compressed air before drying. If the winding is seriously wet, it needs to be dried by hot air method first. After drying, dry with load to avoid insulation breakdown. When drying, we should put more thermometers in the parts of industrial diesel genset, so as to grasp the temperature of each part and reduce local overheating. Heating shall be carried out slowly to avoid insulation damage caused by sudden evaporation of moisture in the coil. 2.If the drying temperature does not reach the required temperature, it can be dried at a sli...

As an emergency backup power source, diesel generator sets are increasingly accepted and used by many industries due to its reliability, timeliness and safety. However, purchasing a suitable diesel generator set is not an easy task. If you decide to buy a emergency diesel generator , you are advised to read the below instructions before placing an order. 1. Common Enquiry A. Power supply parameters: output voltage 230V/400V, frequency 50HZ, genset speed 1500r/min. B. Automatic display and recording of operating data: including water temperature, oil pressure, speed and running hours. C. Protection device: diesel engine overspeed, start or stop failure, low oil pressure, high oil temperature, excessive cooling water temperature, generator overload, short circuit, loss of pressure and failure of the vehicle, etc, the genset will give alarm according to different conditions (including lighting, audible alarm), open and even stop automatically. D. It should...
