Why diesel generators! You need to start a fire to have electricity

Foshan Tenghui Boiler Manufacturing Co., Ltd. is a limited liability company specializing in the design, production and installation of boilers and pressure vessels, pressure pipelines and other mechanical and electrical equipment. Contact**: 0757-86255766 The company was converted from the original Guangdong Foshan Boiler Factory.

The company now covers an area of 13,000 square meters, with a plant area of 8,500 square meters, an office building area of 1,500 square meters, and 138 employees, including 28 engineering and technical personnel. There are 38 certified welders, 15 testing personnel, 105 sets of production equipment and testing equipment. The company's main business is as follows:

1.design and production of diesel generators and gas turbine waste heat boilers; ceramic kiln, glass furnace waste heat boiler; cement kiln waste heat boiler; marine waste heat boilers; So far, more than 600 sets of various waste heat boilers have been produced

The diesel generator is used as a backup power source for the accident security section.

In the event of an accident in the event of power interruption (including unsuccessful power supply from the standby plant) during the operation of the unit, in order to ensure the safe shutdown of the unit, an accident safety section must be set up.

The main equipment of this section includes: steam turbine lubricating oil pump, top shaft oil pump, generator seal oil pump, crank, air preheater, fire detection fan, electric feed pump, auxiliary oil pump, blower lubricating oil pump, and various electric door power supplies and other important power supplies. The loss of power to each of the above devices can lead to significant losses.

The air temperature rises during compression, and the sprayed mist diesel fuel produces spontaneous combustion. Diesel engines are also called compression-ignition engines.

Detonate mist diesel with high compression ratio.

It seems that the diesel engine also has an electric lighter.

The main role of diesel generator is to be used as a backup power source, when we need to use a diesel generator, and it does not generate electricity, which is very sad, what are the reasons for the failure of diesel power generation and not power generation? Below we summarize a few common situations:1

The voltmeter of the control panel is damaged or the wiring contact is poor. This situation is generally after the normal start of the diesel generator, the voltage on the instrument sometimes does not move, it is necessary to use a multimeter to measure the U, V, W, N phase of the motor, the phase voltage between U, V, W is about 400V, and the voltage between single-phase U, V, W and N is about 230V. 2.

The air switch on the electric ball in the diesel generator is damaged: the phenomenon that occurs is that the diesel generator is normal when it starts, and it trips when the load is turned on. 3.

Diesel generator configuration of brush motor: the disadvantage of brush motor is that there is occasional degaussing, so you need to keep 1-2 pairs of carbon brushes to prevent this kind of teasing situation. 4.

The starting element is not reached: the starting element of the diesel generator refers to the speed at 1500 rpm, the frequency of 50Hz, the voltage of 400V, many users feel that the noise of the diesel generator will be very large when reaching this data value, and they will reduce the speed by themselves, resulting in the consequence that the voltage is not enough, the frequency is not enough, and the power of the diesel generator is not enough for a long time. 5.

Damage to the regulator: The function of the regulator is to adjust the excitation current according to the change of the generator load, so as to maintain the terminal voltage as a given value, and the smell of burning can be obvious. The above is our summary of the common failure reasons for diesel generators not to generate electricity, we recommend that if your diesel generator is not out of the shelf life, please contact the diesel generator manufacturer to provide guidance on the operation, try not to repair it yourself.

What is the reason why diesel generators can't afford to use electricity after generating electricity? Hello dear, <>

If the diesel generator is out of power, it can be repaired according to the following methods: 1. Wiring error: check and correct according to the line.

2. The excitation winding of the main generator or exciter is connected incorrectly, resulting in incorrect polarity; The mismatch between the polarity of the excitation current of the exciter and the polarity of the permanent magnet often occurs after the excitation winding is replaced due to wiring errors: it should be checked and corrected. 3. Breakdown short circuit of silicon rectifier components

Forward and reverse homogeneous general multimeter to check the forward and reverse resistance of the rectifier element, replace the damaged side element 4, the main generator excitation winding disconnection: use a multimeter to measure the main generator excitation winding, the resistance is infinite, should be connected to the excitation line beam noisy circuit 5, the main generator or exciter windings have a serious short circuit armature winding short circuit, generally obvious overheating. If the excitation winding is short-circuited, the DC resistance value can be used to determine and replace the damaged winding.

Hello dear, I'm glad to answer for you. The failure of a 50 kW diesel generator to generate electricity may be caused by the following reasons:1

Fuel problems: If the diesel quality is not good or the oil circuit is blocked, it will lead to problems such as insufficient combustion and blocked injectors, which will affect the normal operation of the diesel generator. 2.

Electrical problems: If the electrical circuit is faulty, the connection is not tight, etc., it will also cause the generator to not work properly. 3.

Mechanical problems: If there is a mechanical failure in the diesel engine, such as damage to the crankshaft, connecting rod, piston and other components, it will also cause the motor to not work properly. For the above problems, you can troubleshoot the high cavity through the following steps:

1.Check whether the fuel system and air supply system of the diesel engine are normal, such as whether the oil pump, oil nozzle, fuel injector, air filter and other parts are in normal operation and smooth. 2.

Check whether the circuits and electrical appliances of the generator are normal, such as whether the preheating circuit, ignition coil and faulty lights of the generator are normal. 3.Check the mechanical parts of the diesel generator, such as the crankshaft, connecting rods, pistons, etc., for damage, etc.

Why is the electricity emitted by the gasoline generator on fire, but how to deal with it to become a fire and a zero?

Why is the electricity emitted by the gasoline generator on fire, but how to deal with it to become a fire and a zero? Hello dear, you want to go with the circuit! Then just ground any of these wires (zero) them!

If only the line of fire will light up! The two output wires of the portable generator are not grounded at one end! There is no such thing as a line of fire and a line of zero!
