Diesel Generator Tech

A DC generator is a device that converts mechanical energy into DC power. It is mainly used as a DC motor for DC motor, electrolysis, electroplating, electric smelting, charging and excitation of an alternator. The working principle of the DC generator is to change the alternating electromotive force generated in the armature coil by the commutation function of the commutator and the brush, so that it changes from the brush end to the DC electromotive force because the brush A passes through the commutation. The electromotive force drawn by the sheet is always the electromotive force in the side of the coil that cuts the N-pole magnetic field lines. Therefore, the brush A always has a positive polarity, and the same reason, the brush B always has a negative polarity. Synchronous generator, that is, an alternator with the same rotor speed as the rotating magnetic field of the stator. According to the structure, it can be divided into two types: a rotating armature and a rota...

An electric motor is an electrical machine that converts electrical energy into mechanical energy. Most electric motors operate through the interaction between the motor's magnetic field and winding currents to generate force. In certain applications, such as in regenerative braking with traction motors, electric motors can be used in reverse as generators to recover energy that might otherwise be lost as heat and friction. An electric generator operates in the reverse direction, converting mechanical energy into electrical energy. Electric generator can be divided into various type, open type, silent type, trailer type, portable type and container type, etc. Electric generator is mainly composed of diesel engine & alternator. Electric generator set is mainly composed of engine, alternator, control module, and common base. Electric generator :- Electric generator is a type of machine which converts mechanical input (energy) into electrical output (...

Synchronous generator, that is, an alternator with the same rotor speed as the rotating magnetic field of the stator. According to the structure, it can be divided into two types: a rotating armature and a rotating magnetic field. Synchronous generators are one of the most commonly used alternators. In the modern power industry, it is widely used in hydropower, thermal power, nuclear power generation and diesel power generation.A synchronous motor that operates as a generator is one of the most commonly used alternators. In the modern power industry, it is widely used in hydropower, thermal power, nuclear power generation and diesel engine. Electricity. Since the synchronous generator generally adopts DC excitation, when the single machine operates independently, the voltage of the generator can be conveniently adjusted by adjusting the excitation current. If it is integrated into the grid operation, the voltage is determined by the grid and cannot be changed. At this ...

Synchronous motor Synchronous motor is an AC motor that generates a torque by a DC-powered excitation magnetic field that interacts with a rotating magnetic field of the armature to rotate at a synchronous speed. The structure of the synchronous motor is basically the same as that of the  synchronous generator , and the rotor is also divided into a salient pole and a hidden pole. But most synchronous motors are salient. The installation form is also divided into horizontal and vertical. Induction motor An induction motor, also known as an "asynchronous motor", is a device that places a rotor in a rotating magnetic field and obtains a rotational moment under the action of a rotating magnetic field, thereby rotating the rotor. The stator is the part of the motor that does not rotate. The main task is to generate a rotating magnetic field. The rotating magnetic field is not achieved mechanically. Instead, it is connected to a pair of electromagnets by alte...

1. Fault phenomenon of diesel generator overspeed Under normal operation, the engine speed suddenly rises, so that the engine speeds up beyond the rated speed and loses control, and emits a huge roar, the exhaust pipe emits a lot of black smoke or blue smoke. 2. Cause of failure The fundamental cause of diesel engine overspeed is that diesel engine loses or changes its speed regulation characteristics. Faults of fuel injection pump and governor, such as stagnation or looseness of relevant components, will cause excessive oil supply and loss of normal speed regulation characteristics, while the combustion chamber entering additional diesel or oil will change the speed regulation characteristics of diesel engine. 1) Faults of injection pump and speed regulator A. When assembling and repairing, impact the plunger, oil outlet valve seat of fuel injection pump, too much tightening torque will cause the deformation of plunger sleeve, impurities entering into the cl...

Generating Set Control Protection System During the load operation of diesel generator, it is necessary to monitor and control the working condition of the unit at any time, report all kinds of faults accurately and timely, and automatically protect the genset can supply power safely and reliably. The electrical control and protection system of generator is generally composed of integrated controller, sensor, instrument and so on. The function of the sensor is to monitor the temperature, pressure and other signals on the diesel engine and convert these signals into current signals. At present we use more is Deep Sea DC control system. Model includes 520, 550, 560, 5110, 5220, 5510, 7310, 7320 and other controllers. DSE7320 controller is widely used in our power generators no matter it is Cummins generator, Perkins generator, Volvo generator or Chinese brand generator. If it is parallel diesel generator set, we often use DSE8610 or DSE8620 control module. The DSE731...

Engine fuel requirements Fuel: – Use high quality light diesel oil of temperature 0 or lower – Using higher temperature fuel will clog the filter to reduce power – Use higher temperature fuel to make engine starting difficult – Drain the water from the fuel filter in the hot state after shutdown – Replace filters regularly (250h) – If the fuel used is dirty, the filter will be blocked in advance. – Engine power will drop after the filter is clogged. Engine oil requirements lubricating oil: – Viscosity meets SAE 15W40 – Quality meets API CD or higher rating – Change oil and filter regularly (250h) – Must use CF4 or above oil on the plateau – The combustion condition of the engine in the plateau deteriorates, the oil pollution is very fast, and the oil life below the CF4 level is less than 250h. – Exceeding the life of the engine will result in the engine not being properly lubricated, the wear will be intensified, and early failure will o...
