Diesel Generator Tech

Diesel generator sets are commonly used in a variety of sectors due to their dependable performance and high efficiency. They can be used for emergency power supply in the event of a power cut or used in places without connection to a power grid. When selecting a diesel generator for your home or business, you need to consider many factors, such as generator’s ratings. In this article, we’ll explain the three basic rating types - standby, prime, and continuous in diesel generators. ISO-8528-1:2018 defines basic generator set rating categories based on four operational categories: Emergency Standby Power (ESP), Prime Power (PRP), Continuous Power (COP) and Limited-Time Running Prime (LTP). Read on and learn the application of power ratings for engines used in generating sets. Standby Power Rating Standby Power(ESP) is used to supply emergency power when the external power supply is interrupted, such as power outages. Standby power rated generators can supply reliable electricity as t...

Cooling methods of standby diesel generator There are two common ways of cooling diesel generators, air cooling and water cooling. It is the same principle as the engine. Both use the fast-heating and highly fluid substance to take away the temperature in the environment to control the working environment temperature. Water cooling is mainly performed by a water circulation system. The water pump draws cold water into the cold water pipeline and takes away the heat through the water flow wound in the water cooling pipeline on the equipment.   Air cooling is generally installed in the generator room ventilation system, through the exchange of hot and cold air to control the indoor temperature, there are four common ventilation systems:   1). Normal ventilation system: For the ventilation of generator room, it is generally the ventilation volume of 10 to 15 times of ventilation, and only exhaust fans can be set; if there is gas for water supply and drainage, this syste...

After generator starts up, there is no voltage, the most possible reason is the generator has no magnetic field. Why is there no magnetic filed in generator? Fault phenomenon: After standby generator set idle for a long period of time, when restart, there is no AC voltage output. Measure the main output winding, and the voltage between phases is "0" or lower than "5vac". The reason: Generator has not been used for a long time, resulting in losing remanence contained in iron core. The excitation coil can't establish the proper magnetic field. At this time, the generator set runs normally but does not generate voltage. This kind of fault often occurs in new generator set, generator set stored in humid environment or generator set not used for a long time. How to deal with no magnetic field problem of generator? 1.Check the main output circuit of the generator to avoid the excitation cannot be established due to the short circuit at ...

Startup operation 1. Press the start button to start the standby generator . At the same time, pay attention to the presence of mechanical noise, abnormal vibration and so on. 2. During operation, the operator closely monitors the voltage, frequency, current, power factor, oil temperature, oil pressure, water temperature, charging current, speed and other instrument instructions and changes of generator set through the instrument. When the specified value is exceeded, timely inspection and measures should be taken, and the operation can be continued only after returning to normal. 3. The emergency stop button on the control screen panel is only used in case of emergency. After pressing the button, the generator will stop immediately and sound-light alarm will be issued at the same time. 4. After the generator runs normally, close the main switch (low-voltage air switch) of the generator set, and the generator supplies power to the electrical load. Shut down 1. Af...

Diesel generator sets can be divided into two types according to the use situation: one is based on mains power, generator set standby power supply equipment and the other is generator-based power supply equipment. To ensure that the genset is in good condition and prolong the service life of the machine, the technical maintenance system of the diesel engine must be implemented. The technical maintenance categories are divided into: First level maintenance inspection (daily or weekly) Secondary maintenance inspection (every 250 hours or one month) Level 3 maintenance inspection (every 1500 hours or half a year) The standby generator should run regularly for about 10 minutes, so as to evaporate the water in the diesel engine body and achieve moisture and corrosion protection. First level maintenance inspection 1. Check oil level. Use a diesel oil dipstick to check the oil level. In order to obtain accurate readings, the oil level should be checked when th...

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...

Electric generators are, actually the lifesavers. They are backup power sources that convert fuel supply usually propane, diesel or gasoline, into electrical energy. They are the primary sources of electrical supply during power outages. This energy is used in an external circuit. Direct current generators The dynamo was the first electrical generator capable of delivering power for industry. The dynamo uses electromagnetic induction to convert mechanical rotation into direct current through the use of a commutator. Homopolar generator A homopolar generator is a DC electrical generator comprising an electrically conductive disc or cylinder rotating in a plane perpendicular to a uniform static magnetic field. A potential difference is created between the center of the disc and the rim (or ends of the cylinder), the electrical polarity depending on the direction of rotation and the orientation of the field. MHD generator A magnetohydrodynamic generator directly...

1. Classified According to the Control Mode of Generator Set ① Manual Generator Set This type of genset is the most common type.The genset has automatic voltage and speed adjustment functions. The operator can start, close, open and stop the unit at the machine room. This type of genset is usually used as a primary or backup power source. ② Self-starting/ Auto Start Generator Set The self-starting unit is based on the manual unit and has a self-starting control system. When the mains suddenly loses power, the unit has the functions of automatic start, automatic voltage regulation, automatic frequency modulation, automatic switch switching and automatic shutdown; when the unit oil pressure is too low, the oil temperature and the cooling water temperature are too high, it can automatically make a sound. Light alarm signal; when the unit is overspeed, it can automatically stop the unit for emergency shutdown. The advantage of the automation unit is that it greatly increases ...
