How to install diesel generator set?

1. The installation site must be well ventilated. There should be sufficient air inlets at the generator end and good air outlets at the diesel engine end. The air outlet area should be more than 1.5 times larger than the water tank area.

2. The area around the installation site should be kept clean, and items that can generate corrosive gases and vapors such as acid and alkaline should be avoided nearby. Fire extinguishing devices should be equipped where possible.

3. If used indoors, the smoke exhaust pipe must be connected to the outdoors. The diameter of the pipe must be ≥ the diameter of the smoke outlet pipe of the silencer. The connected pipe should not have more than 3 elbows to ensure The smoke exhaust should be smooth, and the pipe should be tilted downward 5-10 degrees to avoid rainwater injection; if the exhaust pipe is installed vertically upward, a rainproof cover must be installed.

4. Basic use When installing concrete, a level must be used to measure its level during installation to ensure that the unit is fixed on a level foundation. There should be special anti-vibration pads or anchor bolts between the unit and the foundation.

5. The unit shell must have reliable protective grounding. For generators that require a neutral point to be directly grounded, the neutral point must be grounded by professionals and equipped with lightning protection devices. It is strictly prohibited to use commercial power generators. The electrical grounding device conducts the neutral point to be directly grounded.

6. The two-way switch between the generator and the mains must be very reliable to prevent reverse power transmission. The wiring reliability of the two-way switch must be inspected and approved by the local power supply department.

7. The wiring of the starting battery must be firm.

First, when Weichai generators are used indoors, the smoke exhaust pipe must be led to the outside. The diameter of the pipe must be the diameter of the smoke outlet pipe of the silencer. The number of elbows in the pipe should not exceed 3. To ensure smooth flow of smoke exhaust, the pipe should be tilted downward by 5-10 degrees to avoid rainwater injection. If the exhaust pipe is installed vertically upward, a rainproof cover must be installed. In order to improve the output power of the diesel generator set, when the cylinder capacity and number are certain, only by forcing more air into the cylinder to fully burn the fuel in the cylinder can the average effective pressure of the unit be increased. Currently, diesel generator sets use turbochargers. The compressor has strict requirements on the exhaust of the diesel generator set. Once the exhaust is not smooth or the exhaust gas speed does not meet the requirements, the air entering the cylinder decreases, which will cause the load capacity of the diesel generator set to decrease.

Second, the area around Weichai generators should be kept clean, and items that can produce acidic, alkaline and other corrosive gases and steam should be avoided nearby. Fire extinguishing devices should be equipped where possible.

Third, the installation site must be well ventilated. There should be sufficient air inlets at the Weichai generator end and good air outlets at the diesel generator end. The air outlet area should be more than 1.5 times larger than the water tank area; the air inlet is not smooth or does not meet the requirements, and less air enters the cylinder, which will cause insufficient fuel in the cylinder, produce carbon deposits, and affect the load capacity of the diesel generator set. ; Similarly, if the exhaust pipe does not meet the requirements and the oxygen content of the air in the engine room is reduced, it will also cause insufficient fuel in the cylinder, produce carbon deposits, and affect the load capacity of the diesel generator set.

Fourth, when the foundation is made of concrete,During installation, a level ruler must be used to measure the levelness, so that the unit can be fixed on a level foundation. There should be special anti-vibration pads or anchor bolts between the unit and the foundation.

Fifth, the unit shell must have reliable protective grounding. For generators that need to have a neutral point directly grounded, the neutral grounding must be carried out by professionals and equipped with lightning protection devices. It is strictly prohibited to use commercial The electrical grounding device conducts the neutral point to be directly grounded.

Sixth, the two-way switch between the generator and the mains must be very reliable to prevent power transmission. The wiring reliability of the two-way switch needs to be inspected and confirmed by the local power supply department.

If the air intake volume is taken directly from the basement, it can be taken directly from the basement.

Generators convert other forms of energy into electrical energy. Mechanical equipment, which is driven by a water turbine, steam turbine, diesel engine or other power machinery, converts the energy generated by water flow, air flow, fuel combustion or atomic nuclear fission into mechanical energy and transmits it to the generator, which is then converted into electrical energy. Generators are widely used in industrial and agricultural production, national defense, science and technology and daily life.

Generators come in many forms, but their working principles are all based on the law of electromagnetic induction and the law of electromagnetic force. Therefore, the general principle of its construction is: use appropriate magnetic and electrically conductive materials to form magnetic circuits and circuits that conduct electromagnetic induction with each other to generate electromagnetic power and achieve the purpose of energy conversion.

Diesel generator

The diesel engine drives the generator to run, converting the energy of diesel into electrical energy. In the diesel engine cylinder, the clean air filtered by the air filter is fully mixed with the high-pressure atomized diesel fuel injected from the injector. Under the upward squeeze of the piston, the volume shrinks and the temperature rises rapidly, reaching the ignition point of the diesel fuel. The diesel is ignited, the mixed gas burns violently, expands rapidly in volume, and pushes the piston downward, which is called 'work'.
